Succinct launches the iPhone app Zcam, enabling encrypted signature verification for photos and videos.

According to Cointelegraph, cryptography firm Succinct has launched Zcam, an iPhone camera app that enables real-time cryptographic signing of photos and videos upon capture, thereby verifying content authenticity and reducing risks associated with AI-generated or tampered content. The app hashes the original image data and signs it using a key generated within Apple’s Secure Enclave, then embeds the signature, capture metadata, and attestation information into the file in accordance with the C2PA standard. Succinct states that Zcam can be applied in scenarios such as journalism, insurance claims, and identity verification; however, its SDK has not yet undergone security audit and is not production-ready.
