"C2PA's Content Credentials are a tamper-evident, cryptographically signed digital manifest providing verifiable provenance for digital content such as images, videos, or audio files. The metadata type, according to Adobe, serves as a "digital nutrition label," giving information about the creator, how it was made, and if it was generated using artificial intelligence (AI)."
""The Pixel Camera app achieved Assurance Level 2, the highest security rating currently defined by the C2PA Conformance Program," Google's Android Security and C2PA Core teams said. "Assurance Level 2 for a mobile app is currently only possible on the Android platform." "Pixel 10 phones support on-device trusted time-stamps, which ensures images captured with your native camera app can be trusted after the certificate expires, even if they were captured when your device was offline.""
Pixel Camera and Google Photos on Pixel 10 include C2PA Content Credentials to verify origin and history of images, videos, and audio using tamper-evident, cryptographically signed manifests. Content Credentials function as a digital nutrition label that records creator information, how content was made, and whether artificial intelligence was used. The Pixel Camera app achieved Assurance Level 2 under the C2PA Conformance Program, a mobile-app security tier currently only possible on Android. Pixel 10 supports on-device trusted timestamps so captures remain trustworthy after certificate expiration even when taken offline. The implementation uses Google Tensor G5, Titan M2, hardware-backed Android security, and Android Key Attestation to ensure device authenticity while preserving non-personal provenance data.
