Sony has launched a major expansion of its Camera Authenticity Solution, introducing video verification technology designed to ensure the integrity of visual content used in news production. The update extends Sony’s digital signature and verification system—previously limited to still images — to support video, offering a new layer of transparency for media organizations.
The solution verifies that footage originates from an actual camera rather than being created or altered by AI. It uses proprietary metadata and 3D depth information from Sony cameras to confirm the authenticity of recorded subjects. A new trim function allows users to verify specific segments of video without breaking authenticity signatures, improving efficiency for large media files.
Sony’s Ci Media Cloud platform now also supports C2PA-compliant signature display, enabling journalists and editors to confirm the provenance of both still and moving images directly within their workflow.
The video verification capability will be available as a paid service requiring a digital signature license installed on compatible Sony cameras. Following the PXW-Z300 — introduced earlier this year as the first authenticity-ready video camera — support now extends to the Alpha 1 II, Alpha 9 III, and Cinema Line FX3 and FX30 models. The Alpha 7R V, Alpha 7 IV, and Alpha 1 will gain support in late 2025, followed by the Alpha 7S III in 2026.
Sony developed the system in line with standards set by the Coalition for Content Provenance and Authenticity (C2PA), of which it is a steering committee member. The company has also collaborated with the BBC’s Research & Development Department to validate the technology in professional environments.
By extending its Camera Authenticity Solution to video, Sony aims to provide newsrooms and broadcasters with verifiable proof of origin for visual content, addressing growing industry concerns over deepfakes and synthetic media.
