Is that photo real?
There's a new way to answer that question. Leica's M11-P, announced in late October, is the world's first camera with support for content credentials, an encryption technology that protects the authenticity of photos taken by the camera. The metadata system can track a photo from shutter snap to publication, logging every change made along the way.
"In the last few years it's become easier to manipulate pictures digitally. Photographers can do it, and when the photos are out on the Web, other people can do it," says award-winning photographer David Butow. "I think that puts in jeopardy the strength of photography, the sense that it's a true representation of what someone saw."
In 2019, Adobe, The New York Times, and Twitter partnered to solve that problem by founding the Content Authority Initiative (CAI) in November. (Twitter left CAI after Elon Musk purchased the company.) CAI, which now boasts over 200 partners, gave itself the difficult task of finding a "long-term, holistic solution" for verifying the authenticity of photos. In 2021 it joined with another initiative called Project Origin to form the Coalition for Content Provenance and Authenticity (C2PA).
