PhotoGuard, created by researchers at MIT, alters photos in ways that are imperceptible to us but stops AI systems from tinkering with them.

What happens if you take a picture of the screen with your phone? Not ideal in terms of quality but I’m willing to bet it would work as a stupid easy bypass.

What I’d like to see is an image format that is digitally signed by default so that modifications can be flagged and the source can be verified. Yeah people could modify them for malicious use cases (I don’t think it will be possible to ever prevent that unfortunately) but at least we’d know that it wasn’t the original. This doesn’t work for cases where people want to be anonymous but for things like social media selfies and posts where people are visible it could be helpful in preventing people spreading deepfakes and claiming they’re real.

A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.
