About Encypher. Proof of who signed it, carried in the work.
We wrote the C2PAC2PA: The Coalition for Content Provenance and Authenticity: the group that publishes the open standard for content labels. standard for labeling text. Our label shows who made a piece of work, whether AI helped, and whether it changed. Anyone can check it, free.
Why we built it.
- Work gets copied, quoted and fed to AI every day. The name of the person who made it rarely goes along.
- 400+ companies, like Adobe, Google, OpenAI and the BBC, are members of the C2PA. It sets the open standard for content labels.
- Text had no way to carry a label, so we wrote one: the standard for unstructured textUnstructured text: Text with no file around it, such as an article body, a post or a chat reply, so there is no container to hold a label.. Now we build the tools that sign and check it.
