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.

'Woke tech' and 'the new slave power': Conservatives gather for Vegas summit

An agenda for the event, hosted by the Claremont Institute, listed speakers including U.S. CTO Michael Kratsios and Texas Attorney General Ken Paxton.

Conservative investors, political operatives, right-wing writers and Trump administration officials are quietly meeting in Las Vegas this weekend to discuss topics including China, "woke tech" and "the new slave power," according to four people who were invited to attend or speak at the event as well as a copy of the agenda obtained by Protocol.

The so-called "Digital Statecraft Summit" was organized by the Claremont Institute, a conservative think tank that says its mission is to "restore the principles of the American Founding to their rightful, preeminent authority in our national life." A list of speakers for the event includes a combination of past and current government officials as well as a who's who of far-right provocateurs. One speaker, conservative legal scholar John Eastman, rallied the president's supporters at a White House event before the Capitol Hill riot earlier this month. Some others have been associated with racist ideologies.
