Google releases Credentio open-source C++ library for content provenance

Google has released Credentio, an open-source C++ library designed for the local validation of C2PA (Coalition for Content Provenance and Authenticity) Content Credentials. The library supports C2PA specification versions 2.2 and 2.4.

By enabling validation to occur locally within developer applications, Credentio eliminates the need to transmit media files to cloud servers or external endpoints. This approach is intended to improve data privacy, reduce latency, and minimize bandwidth and file size limitations. The tool is designed for high-throughput workflows and features a small memory footprint, making it suitable for resource-constrained client applications, server pipelines, or edge software.

Google stated that this code has already powered nearly 40 of its own C2PA-enabled products, managing tens of billions of assets including images, videos, audio, and documents. While the current focus is on validating existing credentials, Google plans to expand the library to support the creation and embedding of Content Credentials as the C2PA specification evolves.
