en.Wedoany.com Reported - Google has announced the release of Credentio, an open-source C++ library designed for C2PA (Coalition for Content Provenance and Authenticity) content credentials.

Credentio was released on August 13, with its code hosted in the mediaprovenance repository. Its API is designed to run locally within developers' applications, eliminating the need to send media files to cloud servers for verification, thereby circumventing limitations related to privacy, latency, bandwidth, and file size.

The library supports C2PA specification versions 2.2 and 2.4. According to Google, the same codebase already powers nearly 40 different C2PA-compliant Google products, covering images, videos, audio files, and documents in multiple file formats, with cumulative assets generated reaching tens of billions.

Google states that when using Credentio, media files do not need to be sent back to Google or any external verification endpoint, achieving zero bandwidth overhead while also delivering instant verification results and complete data privacy. Since the verification process is performed locally, external data transmission is entirely eliminated, verification latency is minimized, and responses are immediate even in high-throughput workflows, while the media content itself always remains within the local environment.

Credentio is primarily aimed at developers who need to build high-performance, enterprise-grade C2PA verifier products. According to Google, the library has a small memory footprint, making it suitable for integration into resource-constrained client applications, server-side pipelines, or high-performance edge software.
