TechFlow news: On May 20, according to official announcements, Brevis Vera—the media authenticity verification tool launched by Brevis, a ZK-powered intelligent verifiable computing platform—has now been fully opened to the public.
According to the introduction, users can capture images using any camera or smartphone supporting C2PA. C2PA enables devices to cryptographically sign media content at the moment of capture, binding the content to the hardware and generating tamper-proof provenance metadata.
After uploading an image to Brevis Vera, users may perform editing operations. Leveraging the Brevis Pico zkVM, every editing step is traceable and verifiable. Upon publishing, users receive two files: (1) the edited image (in PNG format); and (2) a proof file (in .bvproof format), which records the original signature and every editing operation. This ensures end-to-end privacy protection for both the original media and the editing process, while enabling anyone to verify—directly via a web browser—that the image was genuinely captured by the hardware device, underwent only permitted edits, and contains no hidden or added content.
Brevis Vera represents a significant milestone in Brevis’s mission to build “the world’s best ZK technology.” By shifting the challenge of media authenticity verification from “detection” to “provenance,” Brevis Vera overcomes the latency inherent in traditional AI-based detection methods, delivering more efficient and trustworthy verification. Over the coming weeks, several professional photographers specializing in nature, wildlife, and portraiture will publish their captured, edited, and proofed works using Brevis Vera—and share their perspectives on verifiable image provenance through a series of podcasts and dialogues.
