Brevis image provenance tool Brevis Vera is now open, introducing zero-knowledge proofs in image provenance.
Foresight News reports that zero-knowledge proof infrastructure project Brevis has officially launched its image provenance tool, Brevis Vera, which is now open to all users. Users can take pictures with C2PA-compatible cameras or smartphones, perform editing operations such as cropping, exposure, and color adjustments in Vera, and then generate a zero-knowledge proof file that any third party can independently verify in a browser, thus fully proving the source and processing chain of the image without disclosing the original media or editing process privacy.
Brevis Vera was introduced this March as an interactive concept demo; the newly launched full version integrates zero-knowledge proof mechanisms into the C2PA protocol stack. It is designed to serve as a complementary primitive that existing editing tools such as Adobe Photoshop can adopt, rather than as a competing substitute.
