A phone chip might help solve the deepfake problem

A new approach to fighting deepfakes aims to flip the problem on its head: Instead of trying to spot what's fake, a startup called Truepic aims to use smartphone chips to prove what's real.


So far, most attempts to deal with deepfakes have been about detection. But Sherif Hanna, VP of R&D at Truepic, thinks that approach has "systematic issues." Any deepfake detector will be used to train a new generative adversarial network to out-forge the detector. "You're forever stuck in this arms race," Hanna said.

Instead, Truepic thinks images should be signed as authentic at the time they're taken, with accompanying location metadata. Social networks could then use that information to confirm accuracy — and take a closer look at images without that data.

Today, Truepic announced that it's partnered with Qualcomm to enable image authentication on a Snapdragon chip. The technology, Qualcomm VP Manvinder Singh said, enables an image to be captured securely from the camera sensor and moved into the Trust Zone Execution Environment to do the processing and add metadata. By using security features typically reserved for payments and facial authentication, "there is no way for any software running on the device ... to manipulate [the image metadata] in any way," Hanna said.

If you take a screenshot of the camera viewfinder, it turns up black. "The Android operating system literally does not see these pixels at all," Hanna explained.

The partnership with Qualcomm, whose chips are in around a third of the world's new smartphones, could help the technology get the widespread traction. Images produced by the tech are compliant with the Content Authenticity Initiative's standards, so social media platforms should be able to easily act on the metadata. At first, though, Hanna is moving forward slowly. "We don't want to foist a new technology on users before they're comfortable with it," he said, pointing to some of Big Tech's recent missteps. Rather than being the default option, he thinks it should be offered as a distinct "Secure" mode in camera apps.

That decision ultimately comes down to phone manufacturers, who now have to decide whether they want to enable the technology at all. It sounds like they might, though. "Initial discussions [with OEMs] have been pretty exciting," Singh said, with Hanna suggesting that the first partnerships will be announced soon. The team is also working on improving the technology, he said, with video a priority.

After a year and a half of living and working through a pandemic, it's no surprise that employees are sending out stress signals at record rates. According to a 2021 study by Indeed, 52% of employees today say they feel burnt out. Over half of employees report working longer hours, and a quarter say they're unable to unplug from work.

The continued swell of reported burnout is a concerning trend for employers everywhere. Not only does it harm mental health and well-being, but it can also impact absenteeism, employee retention and — between the drain on morale and high turnover — your company culture.

Crisis management is one thing, but how do you permanently lower the temperature so your teams can recover sustainably? Companies around the world are now taking larger steps to curb burnout, with industry leaders like LinkedIn, Hootsuite and Bumble shutting down their offices for a full week to allow all employees extra time off. The CEO of Okta, worried about burnout, asked all employees to email him their vacation plans in 2021.

Facebook wants to be like Snapchat

Facebook is looking to make posts disappear, Google wants to make traffic reports more accurate, and more patents from Big Tech.

Facebook has ephemeral posts on its mind.

Welcome to another week of Big Tech patents. Google wants to make traffic reports more accurate, Amazon wants to make voice assistants more intelligent, Microsoft wants to make scheduling meetings more convenient, and a ton more.

As always, remember that the big tech companies file all kinds of crazy patents for things, and though most never amount to anything, some end up defining the future

Protocol | China

China’s edtech crackdown isn’t what you think. Here’s why.

It's part of an attempt to fix education inequality and address a looming demographic crisis.

In the past decade, China's private tutoring market has expanded rapidly as it's been digitized and bolstered by capital.

Beijing's strike against the private tutoring and ed tech industry has rattled the market and led observers to try to answer one big question: What is Beijing trying to achieve?

Sweeping policy guidelines issued by the Central Committee of the Chinese Communist Party on July 24 and the State Council now mandate that existing private tutoring companies register as nonprofit organizations. Extracurricular tutoring companies will be banned from going public. Online tutoring agencies will be subject to regulatory approval.

It’s soul-destroying and it uses DRM, therefore Peloton is tech

"I mean, the pedals go around if you turn off all the tech, but Peloton isn't selling a pedaling product."

Is this tech? Or is it just a bike with a screen?

One of the breakout hits from the pandemic, besides Taylor Swift's "Folklore," has been Peloton. With upwards of 5.4 million members as of March and nearly $1.3 billion in revenue that quarter, a lot of people are turning in their gym memberships for a bike or a treadmill and a slick-looking app.

But here at Protocol, it's that slick-looking app, plus all the tech that goes into it, that matters. And that's where things got really heated during our chat this week. Is Peloton tech? Or is it just a bike with a giant tablet on it? Can all bikes be tech with a little elbow grease?
