Sony is extending its verification technology to a broader lineup of cameras.
The initiative marks the next step in providing news organisations with the industry’s first camera authenticity solution compatible with video, including compliance with the C2PA standard.
C2PA, the Coalition for Content Provenance and Authenticity, is an organisation that develops open standards and technical specifications for the provenance and authenticity of digital content.
Sony is also announcing the next stage of its Camera Authenticity Solution: The system now allows the verification of video in addition to still images. The paid service will initially be provided to news organisations. Beyond verifying that video content was captured by an actual camera and not generated by AI or another means, the system uses proprietary metadata including 3D depth information from the camera to accurately confirm that videos depict real subjects. Additionally, a trim function enables quick verification of specific video segments while preserving authenticity signatures, making it efficient for large video files.
To use the signature function in cameras, a digital signature license and its installation on Sony-compatible cameras are required. Sony will provide digital signature licenses for video, which are required for using the camera’s signature function.
Alongside this, Sony’s cloud-based collaboration platform, Ci Media Cloud, will now display C2PA-compliant digital signature information, enhancing content authenticity for news.
After introducing the PXW-Z300, the world’s first authenticity-ready camera for video this summer, Sony’s Alpha 1 II, Alpha 9 III, Cinema Line FX3 and FX30 will from now on support the recording of C2PA compliant provenance information directly into video files. The interchangeable-lens cameras Alpha 7R V, Alpha 7 IV, Alpha 1 are scheduled to be supported from November 2025 or later, and the Alpha 7S III is scheduled to be supported from 2026 onwards.
