Not all kids’ laptops are Chromebooks, but all Chromebooks are good for kids. These cloud-based devices have security features that most antivirus software can’t even achieve — plus, they’re usually ultra-portable and super cute. Here are the best ones for kids of all ages.

The assumption that Chromebooks are specifically kids laptops makes sense. They’re typically smaller and more lightweight than traditional laptops, and can hold up well against drops or spills. They usually don’t have fast processors, 4K screens, or many other high-end specs that kids just don’t need, which slashes the price big time.

But there’s a more serious aspect that makes Chromebooks a no-brainer for cautious parents: They’re some of the most secure devices on the market. On top of traditional “stranger danger” worries, parents are likely concerned about their family’s data getting into the wrong hands.

Actually, parent or not, every paranoid internet user should have a Chromebook. Don’t @ us. 

The most obvious reason is that Chromebooks are cloud-based. Almost anything you do is automatically backed up on Google Drive, so you won’t lose all of your files if your Chromebook breaks — or if your kid forgets to save a school paper. Updates are automatic as well.

Google’s Chrome OS is a hardcore bodyguard in itself. Every web page or Chrome app runs its own sandbox, essentially ensuring that other parts of the computer won’t be compromised even if that page gets hacked or “infected.” However, a Chromebook probably won’t get a virus: Most malware is designed for Windows or Mac and ignore Google’s OS (for now). If something sketchy were to happen, the threat can be wiped out by closing the page or reverting to factory settings. These security features are a huge part of why nearly three out of every five machines in schools use Chrome OS.

Monitoring kids’ usage on the cloud can’t be done with downloadable parental control software. The easiest way to set limits is to take advantage of your router’s parental control features (Google Nest and Eero are great) or invest in a filter for your home network, like Circle with Disney. These let you manage things like screen time and blocked sites on every device connected to your home WiFi. Upon setup, it’s suggested that parents be the first person to create an account. The first account to log in is seen as the “owner” of the Chromebook, and the owner is who gets to control the settings on other accounts.

How to choose the right Chromebook for your kid

Some Chromebooks are lightweight and some are bricks. Younger kids will probably do better with compact laptops with military-grade durability that can handle a drop from the table.

Storage isn’t a huge deal when most everything is stored in the cloud. (Google Drive comes with 15GB for free.) However, if your kid will be downloading something like textbooks, you might consider a Chromebook with more storage or with an SD card slot to expand storage. Most have 32GB, basic models have 16GB, and nicer models stretch to 64GB.

If your kid uses Microsoft Office for school, you’ll need a Chromebook that can run Android apps from the Google Play Store. Most are Android-compatible, but some fumble with non-Chrome apps.

Chromebooks for entertainment versus Chromebooks for actual work

No one is buying a Chromebook to use power-sucking software like Photoshop. That means that Chromebooks don’t need a lot of RAM, which is what determines how many tasks your computer can keep track of at once. But even with the draining apps reserved for MacBooks out of the picture, Chromebooks still aren’t one-size-fits-all when it comes to daily tasks. When is it time to bypass the average Chromebook 4GB RAM for 8GB or 16GB?

Kids using a Chromebook primarily for media consumption — streaming Disney+ or Youtube, playing games, or using light educational programs — could easily scoot by with 4GB, which is more than capable enough to handle anything that’s not super involved when it comes to data or graphics.

Bumping up to a beast like the Google Pixelbook Go or Slate and their 8 or 16GB RAM is the wise move if your kid is regularly using the Chromebook for more than entertainment purposes. We’re talking demanding programs like statistics software or storage of huge textbooks — any heavy-duty stuff outside of the Microsoft Word or Google Docs realm. Bigger workloads require more RAM to allow the computer to operate smoothly and avoid the ominous frozen screen. Such desktop-esque models are also more likely to have juicier displays and processors, more versatile ports and memory card slots, and backlit keyboards.

Here are the best Chromebooks for kids in 2021:

Boots up in 10 seconds or less • Super lightweight • Compact keyboard for small hands • Comes with a free one-year trial of Google One • One of the only decent Chromebook tablets on the market

Only one port (USB-C) • No headphone jack

A surprisingly capable Chromebook for the price that’s safe to carry around.

Lenovo Chromebook Duet

Lenovo’s true detachable Chromebook has impressive specs for its price, and you don’t need to buy a separate keyboard.

  • Battery life:
    10 hours
  • Weight:
    2.03 pounds total (0.99 pounds without keyboard)
  • Display:
    1920 x 1200
  • RAM:
  • Storage:
If it feels like someone’s always hogging the family desktop, it wouldn’t hurt to grab a laptop specifically for homework time. Enter: the , a remarkably lightweight 2-in-1 laptop with a solid general-purpose processor, a built-in kickstand, and a compact, detachable keyboard that’s perfect for small hands. (Many laptop-tablet hybrids don’t come with their own keyboards — see: the and its separate — making the Chromebook Duet a stellar value at under $300.) Its 10.1-inch touchscreen display is also compatible with Universal Stylus Initiative (USI) pens for drawing and doodling, but you’ll have to buy one of those separately. 
The really great thing about the Chromebook Duet is that it comes with a free one-year trial of Google One on top of 128GB of internal memory. (That alone is a ton of storage for a Chromebook.) That’ll get you an additional 100GB of cloud storage for assignments, essays, study guides, and notes. 

SSD over eMMC storage • Acer VertiView display is super sharp • 3:2 aspect ratio looks stunning

No stylus included, but is compatible with some separate pens • Not super lightweight

Acer Chromebook Spin 713

glorious hi-res with unique aspect ratio that blows competitiors out of the water

  • Weight:
    3.02 pounds
  • Display:
    2256 x 1504

Of the million 2-in-1 iterations with near-indistinguishable differences the Chromebook market has to offer, tech publishers have been able to agree that one beats the rest: Acer’s Chromebook Spin 713. 
This particular Spin model sets itself apart with a rare 3:2 aspect ratio (a small layout change known as a productivity boost) and crisp VertiView display, which makes colors pop and tiny words legible. A laptop over three pounds might be a struggle for some youngsters, but it’s an expected weight jump for 13.5-inch screen.
The of an included stylus is annoying for a price point like this. But it hasn’t been enough to squash the internet’s love for this Chromebook, especially because it is technically compatible with a few USI pens. 

Great with Android apps • Terrific battery life • A breeze to carry around • Keys are well-spaced and comfortable • Great choice for internet safety while studying abroad

Touchscreen with no 360-degree hinge is odd

Google found a way to revamp the Pixelbook by adding a faster processor and *really* satisfying keyboard.

Google Pixelbook Go

Arguably the best bang for your buck on the market, the Pixelbook Go is lightweight and a total powerhouse.

  • Battery life:
    Up to 12 hours
  • Weight:
    2.2 pounds
  • Display:
    1920 x 1080 touchscreen
  • RAM:
  • Storage:
    64GB eMMC
The world has its share of Chromebook non-believers. The sluggish plastic ones aren’t changing any minds, but Google’s Pixelbook Go will. Under the hood, features like an 8th gen i5 processor (the same CPU that powers the 2018 MacBook Air) and up to 16 GB of RAM give the Pixelbook Go significantly more oomph than casual Chromebooks.
The Samsung Galaxy Chromebook is the only sensible competition here. But let’s be real: kids (and most adults) don’t need that 4K screen or that much power, especially for Samsung’s $1,000 price tag. The Pixelbook Go is certainly beastly enough for school projects and running multiple energy-sucking apps at once.
Google opted out of the 360-degree hinge, but tech bloggers agree that the traditional notebook design feels sturdier and more professional. The rounded corners and muted colors scream ~maturity.~

Frequently on sale for $349.99 • Selfie camera • Built-in battery-free stylus • Two USB ports and a microSD slot • New Intel processor offers speed boost

Too expensive when it’s not on sale • Keyboard isn’t backlit • No HDMI

It’s compact and comes with a stylus that never needs to charge, so kids are set while traveling.

Samsung Chromebook Plus V2

The included battery-free pen will be a game changer for school and creative projects alike.

  • Battery life:
    9.5 hours
  • Weight:
    2.98 pounds
  • Display:
    1920 x 1200
  • RAM:
    4 GB
  • Storage:
    32GB eMMC
Foldable Chromebooks with stylus support are solid outlets for creativity. There’s just something fun about paperless writing or drawing, whether that’s designing in Adobe or highlighting a virtual textbook. Not only does Samsung’s Chromebook Plus V2 support styluses — it comes with one that never needs to be charged.
The second generation of Samsung’s budget 2-in-1 Chromebook ain’t no Galaxy Chromebook, but it’s a hell of a value for its price range. A new Intel processor gives it an edge over the original, but it keeps the same aluminum clamshell design and sturdy 360-degree hinges.

Spill-resistant keyboard • Sturdy build with rubber bumpers • 2-in-1 touchscreen adds fun flare • Safe and easy to throw in a backpack • Headphone jack

Dinky touchpad • Display isn’t FHD

Dell’s sturdy 2-in-1 nails the kid-ready checklist with drop and spill resistance.

Dell Chromebook 11 3100

A flippable touchscreen puts a fun, modern touch on Dell’s durable little laptop.

  • Battery life:
    10 hours
  • Weight:
    2.85 pounds
  • Display:
    1366 x 768
  • RAM:
    4 GB
  • Storage:
    32 GB
Handing a device to a kid is like watching a drop or spill flash before your eyes. Designed to withstand the rigors of daily life in the classroom, at home, and in between, this 2-in-1 Dell Chromebook nails the kid-ready trifecta: rugged, affordable, and ready for streaming. Its lack of curb appeal is supplemented with 360-degree hinges to switch to tent mode or table mode — automatically more fun.
At just over 11 inches wide and less than three pounds, the 3100 can be carried safely in little arms or little backpacks. The sturdy chassis is supported by rubber bumpers for absorbing shock and a spill-resistant keyboard that can handle 12 ounces of liquid.

Audio is surprisingly clear • Can handle multiple tabs without lagging • Lightweight and grip-able • Supports Android apps • Often on sale for under $200

No HDMI, SD card slot, or USB-C • Screen is dim and washed out • Not much storage

Web browsing and educational apps are probably the extent here, but battery life makes up for it.

HP Chromebook 11

There’s not much power under the hood, but this little guy will surprise you with how it handles tabs and online games.

  • Battery life:
    Up to 12.5 hours
  • Weight:
    2.3 pounds
  • Display:
    1366 x 768, non-touchscreen
  • RAM:
  • Storage:
    16GB eMMC
Kids are expensive even before they ask for a computer. If you’re looking for a decent Chromebook that won’t make you pay extra for specs your kid won’t even notice, the HP Chromebook 11 is a classic choice. 
This fun little laptop packs a punch for its size and price. It boots up quickly, plays audio loudly and clearly, and the keyboard isn’t cramped. Laptop Mag’s reviewer was able to open 16 tabs (including YouTube) before load times started staggering. The biggest advantage to basic devices is that the batteries are troupers. You could probably get away with not charging it for a day or two.
Important ports like HDMI and an SD card slot are lacking on top of the underwhelming processor. The CPU should have enough juice to cast videos to the TV via Chromecast, though.

Garmin Fenix 6 Pro Solar: A maximalist watch for hardcore, data-loving athletes and explorers https://jimmyspost.com/garmin-fenix-6-pro-solar-a-maximalist-watch-for-hardcore-data-loving-athletes-and-explorers https://jimmyspost.com/garmin-fenix-6-pro-solar-a-maximalist-watch-for-hardcore-data-loving-athletes-and-explorers#respond Mon, 10 May 2021 09:12:41 +0000 https://jimmyspost.com/garmin-fenix-6-pro-solar-a-maximalist-watch-for-hardcore-data-loving-athletes-and-explorers

Built-in solar charging • Top-of-the-line activity tracking and mapping • Battery saving mode

Heavy device • Heart rate monitor isn’t reliable • Significant investment

The Garmin Fenix 6 Pro Solar caters to extreme, niche, and data-driven athletes and adventurers.

Before I tried out the Fenix 6 Pro Solar, all I knew is that it’s one of Garmin’s more maximalist models that’s “tested to U.S. military standards for thermal, shock and water resistance” and priced at $799.99. 

Admittedly that description sounded a little excessive for my purposes as most of my activity comes in the form of running. But I was curious about how user-friendly and useful in general its many features would be.

And it delivers to the military standards — but it’s a great fitness wearable for athletes or adventurers who obsess over data, tracking, mapping, and more. 

The setup process for the Fenix 6 was very similar to that of the Forerunner 945 (and presumably, most other Garmin watches). Having gone through the process recently and already familiarized myself with the Garmin Connect and Garmin Connect IQ apps, the Fenix 6 went even quicker. It was mostly a matter of pairing the partially charged watch with my app and getting the data fields the way I wanted them. The Fenix 6 definitely benefited from being second to test, but it goes to show that anyone with relatively recent Garmin experience will have no problem getting these watches up and running in a matter of minutes.

A battery with built-in solar charging means fewer charge days

A defining feature of the Fenix 6 Pro Solar is the solar component: built-in solar charging, which has the potential to add life to an already long-lasting battery. Depending on how long you’re outside and how sunny it is, you can add up to 2 days of battery life in smartwatch mode (up to 16 days) and 4 hours in GPS mode (up to 40 hours). I have to admit that it was fun to keep an eye on the solar intensity whenever I was outside, and I got away with charging the watch just once in two weeks.

Depending on how long you’re outside and how sunny it is, you can add up to 2 days of battery life in smartwatch mode.

Those battery bumps are nice, but where the solar power really kicks in is the battery saver mode. Without solar, using the battery saver will extend the smartwatch life up to 48 days, and with solar, that number skyrockets to 80 days (nearly 3 months!). I didn’t use the watch long enough to verify either the 48- or 80-day claim, but based on my trial period, I don’t doubt it. Just be sure that if you’re going for the solar version of the Fenix 6, you live and train somewhere sunny enough to make it worth it. Also, know that some features — like using the pulse oximeter and streaming music — will still drain your battery quickly if you aren’t careful.

Fenix 6 is a hefty watch — and can weigh you down at first

In terms of aesthetics, the Fenix 6 definitely leans toward the rugged end of the spectrum. It’s not an attempt at a sleek fashion-meets-function watch, which I appreciate, because it looks exactly as I think a “premium multisport GPS watch” should look: durable, substantial, and full of adventure tools. It also has a nice-sized color display, both a little larger and a little higher resolution than the Forerunner 945 (but honestly a little hard to notice unless you’re comparing them side-by-side).

Side-by-side comparison of Garmin Fenix 6 Pro Solar and Garmin Forerunner 945. Spoiler: It’s hefty.

Fenix 6 is a whopper of a watch.

Fenix 6 is a whopper of a watch.

Size-wise, though, there’s no sugarcoating it: the Fenix 6 is a whopper of a watch. If I thought the Forerunner 945 wasn’t small wrist-friendly, this watch takes that statement to a new level. Although both of them occupy the same amount of space on a wrist, the Fenix 6 is noticeably thicker (15.1 mm versus 13.7 mm) and significantly heavier (85 g for the steel version of the Fenix 6 versus 50 g for the Forerunner 945).

Wearing it, I actually felt a little lopsided while running—especially for the first mile of any run, and whenever I ran uphill. I had my husband take it on a spin for comparison, and even though he’s a much larger human than I am, he agrees: the weight is a little distracting until you adjust to it. Granted, I probably would have gotten used to it over time, but had I tried the Fenix 6 on in a store, the heft would have been a non-starter.

The heart rate monitor is unreliable

Just like the Forerunner 945, the heart rate monitor inside the Fenix 6 is too unreliable to be useful. Wrist-based heart rate trackers are suspect to begin with, and they become even more so when the watch doesn’t make a great seal with the user’s skin (i.e., a big watch on a small hand). Even when I cinched the Fenix 6 strap so tight that it pinched me, my heart rate readings were still way off, so I eventually stopped even checking them. For what it’s worth, my larger-wristed husband thought his readings seemed more accurate.

If you care about having accurate heart rate data, simply purchase a chest strap heart rate monitor, sync it to your watch and app, and know that what you’re seeing is much closer to reality than anything you’ll get from a wrist strap.

Fenix 6 excels at activity tracking outdoors, but not inside

Knowing that Garmin specializes in GPS technology, it’s no surprise that that is where the Fenix 6 really shines. With personal stake in the running tracker, that’s where I spent most of my time, and I was consistently impressed with both the experience and accuracy. I trusted the data (current pace, average pace, elevation change, and such) as much or more than any GPS watch I’ve used before. It’s also worth mentioning that the mapping capacity of the Fenix 6 is quite advanced, detailed enough to turn even questionable navigators such as myself into confident pathfinders.

Beyond running, the Fenix 6 tracks dozens of other activities that range from the ordinary (various cycling, swimming, running, and cross-training modes, plus hiking, strength training, and several snow sport options) to the less common (indoor climbing, kayaking, and indoor track running) to the obscure (ultra-running, surfing, jumpmaster, tactical, and boating, to name some that aren’t offered by the Forerunner 945). Admittedly, the two activities I had to look up are unlikely to be ones I’ll ever engage in; jumpmaster is for experienced skydivers, and tactical tracks the user’s location and elevation changes and displays current coordinates. 

Maps and data from an outdoor run.

Maps and data from an outdoor run.

Besides the treadmill running tracker, which was both inaccurate and pretty pointless in my opinion, all of the activity modes I tried did a fine-to-great job. However, I got much more out of those that I did outside while covering ground (like walking and running) than those done inside while staying in place (like using an elliptical or stationary bike). The purpose of tracking those, I suppose, is to offer the watch a complete picture of your exercise so you can keep track, and so it can offer you (questionable, at best) estimates of your fitness level and recovery needs.

So many bells and whistles

Given the significant overlap of features with the Forerunner 945 — these watches have way more similarities than differences — here’s a quick rundown of some that are unique to the Fenix 6 Pro Solar:


The Fenix 6 allows you to transfer music from your personal library to your watch, or to stream music and download playlists from Spotify or Deezer, provided that you’re a premium subscriber. One perk of the Fenix 6 is its extra music storage capacity: up to 2,000 songs, versus 1,000 with the Forerunner 945.

The Garmin Fenix 6 Pro Solar was clearly intended for hardcore athletes and adventurers.

Expedition Mode

In addition to the battery saver mode, Fenix 6 users have the option of going into Expedition mode to extend their battery life on multi-day outings. You can still record your activity in this mode, but your watch goes into low power mode, turns off all sensors and accessories, and collects GPS track points just once every hour (although you can add more points as you go if you wish.)

Workout animations 

With the on-screen workout animation feature, the Fenix 6 allows you to do workout classes wherever you are. The watch comes loaded with several yoga, pilates, cardio, and strength workouts, and the Garmin Connect App has more you can download, too. Simply choose your workout in whichever activity category it falls under, press “start,” and follow along as an animated instructor guides you through your class of choice.

On-screen workout animation feature was mediocre.

On-screen workout animation feature was mediocre.

While it’s a nice idea, in theory, the yoga and ab workouts I tried were too stop-and-start to be very effective. I was constantly looking at my watch to see what I was supposed to be doing, and it seemed that as soon as I caught on to one exercise, a string of beeps had started that indicated it was almost time to move on. I suppose if you repeat the same class several times, you can probably get into a better flow. But personally, I’d probably stick to my own routines or follow along with a live or YouTube instructor.

Water depth 

If you regularly find yourself diving into deep waters, the Fenix 6 may be a good choice for you. Its water rating of 10 ATM means it can withstand pressures equivalent to a depth of 100 meters (twice as deep as the Forerunner 945).

Ski resort maps

Frequent skiers are in for a treat, with the 2,000 ski resort maps from around the world that come loaded onto the Fenix 6. The maps show run names and are color-coded by difficulty so skiers never have to wonder where they are or what their next move should be.

MTB grit and flow 

Mountain bike enthusiasts can get more detailed with their data while in MTB mode, which includes grit (overall difficulty rating of a mountain bike ride) and flow (how well a rider maintains speed during a particular ride).  And yes, I absolutely had to look up both definitions.

Worth the high price tag?

The Garmin Fenix 6 Pro Solar was clearly intended for hardcore athletes and adventurers. In addition to the standard smartwatch features of today that include weather, altitude, heart rate, wallet, notifications, and music, it goes beyond in a few distinct areas. 

This model excels in the mapping and activity tracking departments (as Garmin does), offers more than one way to extend battery on long-haul treks (battery saver mode and expedition tracking), and offers features (like MTB Grit and Flow and Jumpmaster) that apply to just a tiny subset of thrill-seekers. If you’re in the military or are an extreme athlete, and data matters to you, you’re probably a good candidate for the Fenix 6 Pro Solar.

That said, most people — myself included — will consider this watch overkill. Its weight alone is a personal deal-breaker, and most of the features that make it unique among smartwatches don’t apply to me since I don’t surf, skydive, deep-dive, mountain bike, or regularly embark on days-long excursions. The $800 price tag can’t be ignored either, especially for those of us who wouldn’t capitalize on all the watch has to offer.

In my mind, the perfect Garmin Fenix 6 Pro Solar user is a large-wristed individual who loves off-road adventures, participates in a wide array of sports and activities (some of them rather obscure), regularly goes hiking or exploring for days at a time, and has never met a metric he or she didn’t like.

Security Threat: Falsified Satellite Images in Deepfake Geography https://jimmyspost.com/security-threat-falsified-satellite-images-in-deepfake-geography https://jimmyspost.com/security-threat-falsified-satellite-images-in-deepfake-geography#respond Mon, 10 May 2021 07:46:37 +0000 https://jimmyspost.com/?p=3022  


Scientists who have identified a potential national security threat from incorrect geography, for example in incorrect satellite imagery, are investigating ways to identify it and take countermeasures. (Image credit: Getty Images)

Deepfake is a portmanteau of “deep learning” and “fake” and refers to a synthetic medium in which a person in an existing image or video is usually replaced by the likeness of another person. Deepfakes use machine learning and AI techniques to manipulate visual and acoustic content with a high potential for deception.

Geographic deepfakes can corrupt satellite imagery, which could pose a national security threat. Scientists at the University of Washington (UW) are investigating this in hopes of finding ways to spot fake satellite images and warn of their dangers.


Bo Zhao, Assistant Professor of Geography, University of Washington

“These are not just Photoshopping things. This makes data look incredibly realistic, ”he explained Bo Zhao, Assistant Professor of Geography at the UW and lead author of the study, in one Press release from the University of Washington. The study was published in the journal on April 21 Cartography and geographic information science. “The techniques are already there. We’re just trying to show the possibility of using the same techniques and developing a coping strategy for them, ”Zhao explained.

Fake locations and other inaccuracies have been part of map creation since ancient times as real places are translated into map form. However, some inaccuracies in maps are created by map manufacturers to prevent copyright infringement.

The director of the National Geospatial Intelligence Agency sounds the alarm

With the proliferation of geographic information systems, Google Earth, and other satellite imaging systems, spoofing is highly sophisticated and risky. The director of the federal agency responsible for geospatial intelligence, the National Geospatial Intelligence Agency (NGA), sounded the alarm at an industry conference in 2019.

“We are currently facing a security environment that is more complex, interconnected, and volatile than it has been in the recent past. In this environment, we have to do things differently if we are to navigate it successfully,” he said . Robert Sharp, according to a report by SpaceNews.

To investigate how satellite images can be forged, Zhao and his team at WU used an AI framework that was used to manipulate other types of digital files. When applied to the field of mapping, the algorithm essentially learns the properties of satellite imagery from an urban area and then creates a deepfake image by transferring the properties of the learned satellite imagery features to another base map. The researchers used a generative machine learning framework in the opposing network to achieve this.

The researchers combined maps and satellite imagery from three cities – Tacoma, Seattle, and Beijing – to compare features and create new images of a city based on the features of the other two cities. The untrained eye could have difficulty telling the differences between real and fake, the researchers found. The researchers examined color histograms, as well as frequency, texture, contrast, and spatial domains to identify the forgeries.

Simulated satellite imagery can serve a legitimate purpose, such as showing how an area has been affected by climate change over time. If there are no images for a period of time, filling in the gaps to provide perspective can provide perspective. The simulations must be marked as such.

Researchers hope to learn how to spot fake images and help geographers develop data literacy tools, much like fact-checking. As technology advances, this study aims to promote a more holistic understanding of geographic data and information so that we can demystify the question of the absolute reliability of satellite imagery or other geospatial data, Zhao explained. “We also want to develop a more forward-looking thinking to take countermeasures such as fact-checking if necessary,” he said.

In an interview with The edge Zhao said the aim of his study was “to demystify the function of absolute reliability of satellite imagery and to raise public awareness of the possible influence of deep falsified geography.” He stated that while deepfakes are widespread in other areas, his article is likely the first to touch the subject in geography.

“While many GIS [geographic information system] Practitioners have celebrated the technical benefits of deep learning and other types of AI for geographic problem solving. Few have publicly recognized or criticized the potential threats from deep fake to the field of geography or beyond, ”the authors say.

US Army researchers are also working on counterfeit detection


Professor C.-C. Jay Kuo, professor of electrical engineering and information technology at the University of Southern California

US Army researchers are also working on a deepfake detection method. Researchers at the US Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory, are working with Professor CC Jay Kuo’s research group at the University of Southern California to investigate the threat deepfakes pose to our society and national security publication from the US Army Research Laboratory (ARL).

Your work will be featured in the newspaper with the title “DefakeHop: A lightweight, high-performance deepfake detector. ” This will be presented at the IEEE International Conference on Multimedia and Expo 2021 in July.

ARL researchers Dr. Suya You and Dr. Shuowen (Sean) Hu found that most of the cutting-edge deep fake video detection and media forensics methods are based on deep learning, which has weaknesses in terms of robustness, scalability, and portability.

“With the advancement of generative neural networks, AI-driven deepfakes have advanced so rapidly that there is a lack of reliable techniques to detect and defend them,” they explained. “We urgently need an alternative paradigm that can understand the mechanism behind the amazing power of deepfakes and develop effective defense solutions with solid theoretical support.”

Based on their experiences with machine learning, signal analysis and computer vision, the researchers developed a new theory and a new mathematical framework, which they call successive subspace learning (SSL) as an innovative neural network architecture. SSL is DefakeHop’s key innovation, according to the researchers.

“SSL is an entirely new mathematical framework for neural network architecture that was developed from signal transformation theory,” said Kuo. “It’s radically different from the traditional approach. It is very suitable for high-dimensional data with short-, medium- and long-range covariance structures. SSL is a complete, data-driven, unattended framework that provides a brand new tool for image processing and understanding tasks like facial biometrics. “

Read the source articles and information in a Press release from the University of Washington, in the journal Cartography and geographic information science, an account of SpaceNews,a publication from the US Army Research Laboratory and in the article entitled “DefakeHop: A lightweight, high-performance deepfake detector. “

UMN Graduates Intentionally Insert buggy Patches into Linux https://jimmyspost.com/umn-graduates-intentionally-insert-buggy-patches-into-linux https://jimmyspost.com/umn-graduates-intentionally-insert-buggy-patches-into-linux#respond Mon, 10 May 2021 07:42:47 +0000 https://jimmyspost.com/?p=2952  

The Linux kernel community and the University of Minnesota (UMN) are under fire. Thanks to an ill-thought-out Linux security project, two UMN graduate students tried to intentionally insert buggy patches into Linux. Greg Croha-Hartman, the well-respected Linux kernel maintainer for the Linux stable branch, responded by banning not only him, but any UMN-connected developers from contributing to the Linux kernel. Now, UMN has addressed the concerns of the Linux kernel developer community. And, in a message Linux Kernel Mailing List (LKML), To Linux Foundation Technical Advisory Board (TAB) And volunteer Senior Linux kernel retainers and developers have reported on everything they found When he closely scrutinized UMN academics.

First things first: 435 commits coming from UMN-connected developers were re-reviewed. “The vast majority of the reviewed commits were found to be correct.” Of the rest, 39 commitments were incorrect and needed fixing; 25 was already decided later; 12 Now it does not matter; 9 were created before the convict research group came into existence and one commit was removed at the request of its author.

Five deliberately corrupt changes were presented to LKML. “These changes were introduced using two fake identities, which is against documented requirements for how to contribute code to the Linux kernel. The university has allowed researchers to use fake identities if they agree.”Certificate of origin, ‘A legal statement about the work being presented. “

However, contrary to what the researchers, QC Wu and Aditya Paki, and their graduate advisors, Kangji Lu, claimed to be an assistant professor in the UMN computer science and engineering department paper “On the feasibility of introducing stealth in open-source software via the Hypocrit Commit, “Aka” Hypocrite Commits “TAB, stated in clear detail that” all patch submissions that were invalid were caught or ignored by Linux kernel developers and maintainers. Our patch-review processes were intended when confronted with these malicious patches. “

Nevertheless, although no new attacks were found, the kernel developers felt that this was to be heavily reviewed. As Croha-Hartmann told me, “We absolutely should have.” This is because there was also a possibility, no matter how small, that the program intentionally placed corrupt code.

Meanwhile, UMN responded favorably to most requests from the Linux Foundation TAB. Later de UMN gave full disclosure to the Linux community about who and how to conduct the Hypocrite Commits project.

Looking ahead, the Linux community wants to work with UMN again if the school “improves the quality of the changes that are proposed to be included in the kernel.”

On Linux side, TAB members wrote: “TAB, working with researchers, explaining best practices for all research groups to follow when working with kernels (and open-source projects in general) Will create a document. “

Specifically, with UMN, since trust has been lost, TAB asks that UMN, as many companies and other research organizations do:

Designate a set of experienced internal developers to review proposed internal changes and provide feedback before those changes are publicly presented. This review captures obvious mistakes and considers the need to repeatedly remind developers of primary practices such as adherence to standards and thoroughly test standards. This is the result of a high-quality patch stream that will encounter fewer problems in the kernel community.

Until that is done, “patches from UMN will continue to find a chilly reception.”
