Brevis officially launches Brevis Vera, a ZK-based media verification tool

Brevis has officially launched Brevis Vera, a zero-knowledge-based tool for verifying media authenticity, the company announced today. The service, first released in demo form in March, is now fully operational and open to the public. Through the tool, users can upload photos with C2PA signatures, edit them, and then download a cryptographic proof file verifying that all edits are linked to the original image. The proofs are generated using Brevis's zkVM-based system, Pico Prism 2.0, and can be verified by anyone directly in a web browser along with the image. According to the Brevis team, Vera addresses the challenge of media authenticity by adopting a provenance approach that tracks the history of creation and edits, rather than relying on AI to detect AI-generated content.
