What’s being done to combat deepfakes? AI’s are being trained on fakes to make them easier to identify. They look for things like subtle patterns of irregular pixels, tone modulation in voice, and blood flow through the skin for example. FakeCatcher, developed by Intel, looks for subtle biometric data in the pixels of a video that makes us human. Sentinel, another deepfake identifier, is trained to examine facial expressions, blinking
patterns, audio manipulation, and natural language processing. New deepfake detectors are being announced daily.
Digital watermarking, another software technique, embeds information about the source of an image, video or audio, and lets software track the source to make sure it’s being used and attributed properly. Unlike the watermarks you see stamped on images at sites like Getty and Shutterstock, these are invisible digital watermarks that usually come in the form of
embedded code and typically use stenographic techniques and extraction algorithms to track the asset.
Not saying that all digital identities are bad things, either. There’s a lot to be said about owning your digital identity and using it as a source of royalties and income. Say Tom Hanks really wants to do a film, a video, an animated voice film and a TV commercial at the same time. Hand (Human and Digital) has created a system for registering and verifying digital likenesses, and tracking their monetization. Only big talent agencies and celebs will afford it at first, but it’ll trickle down to us mere mortals eventually.
But software isn’t the only solution. Regulations and technical standards play their part. Governments are enacting regulations surrounding deepfakes. (HInt: The US is lagging behind the UK, EU, China and Singapore.) The Coalition for Content Provenance and Authenticity (C2PA) is an industry group of heavy hitters, including Adobe and Microsoft, that’s addressing the prevalence of misleading information online through
the development of technical standards for certifying the source and history (or provenance) of media content.
TikTok, YouTube and Meta are all beginning to require some sort of labeling of AI content. Fearing election deepfakes, OpenAI launched a new deepfake detector for disinformation researchers, designed to help identify fake content generated by its own DALL·E 2
image generator.
Once again, technology forces us to play cops and robbers, Like computer viruses before it, it’s unlikely there will be one silver bullet to solve the deepfake problem but a suite of solutions working together may help control the damage. |
