The massification of generative AI has intensified concerns regarding the authenticity of digital content. This is especially true for news reporting and broadcasting. With that in mind, Sony is expanding its verification technology with a solution designed to confirm the integrity and origin of video.
This initiative provides professionals with the means to verify content recorded on specific Sony cameras. The solution implements the C2PA (Coalition for Content Provenance and Authenticity) standard, an open framework designed to establish the provenance of digital content. Sony is a member of the C2PA steering committee and integrates its standards directly into its video workflow.
Sony extends Camera Authenticity solution to video to combat AI deepfakes
The process begins with the camera itself. Users must install a paid digital signature license on a supported Sony camera. Once installed, the camera attaches a digital signature and metadata to the video file during recording. This signature allows a dedicated verification site to confirm two key facts: that the content originated from a specific Sony camera and whether the file has been manipulated since its capture.
The technology incorporates an additional layer of verification. Where supported, the system can utilize 3D depth information captured by the camera to increase the accuracy of the verification. This mechanism helps confirm that the video content was recorded of actual, existing subjects.
Tailored for news workflows
The verification process is designed to integrate into the fast-paced news environment. For broadcasters dealing with large video files, a “trim function” allows them to quickly extract and verify specific segments of the footage while maintaining the digital signature. This process notably reduces the time necessary for authentication. Furthermore, Sony’s cloud platform for video production, Ci Media Cloud, will display the C2PA-compliant digital signature information.
Sony is rolling out the new video verification capability to a list of professional models. The list includes the Alpha 1 II, Alpha 9 III, FX3, FX30, and the latest PXW-Z300. Sony plans to continue expanding support to more interchangeable-lens and professional camera models throughout 2026. The Alpha 7R V, Alpha 7 IV, Alpha 1 models will arrive in November 2025 or later. Lastly, the Alpha7S III cameras will have to wait until 2026.
