ONVIF Introduces Media Signing Add-on to Authenticate Surveillance Video
ONVIF, a global standardization initiative for IP-based physical security products, has introduced a Release Candidate for its Media Signing Add-on. This new standard aims to establish the origin and integrity of surveillance video through cryptographic signing at the point of creation. The specification is expected to be finalized by the end of 2026. The add-on addresses the growing concern over the authenticity of digital video, especially with the rise of advanced manipulation techniques and AI-generated content. It provides a standardized, technical method to verify if a video file has been altered or if it originated from the claimed device. This development does not render existing surveillance practices obsolete but adds a crucial layer of verification, particularly for footage that may be used as evidence in investigations, insurance claims, or legal proceedings. The add-on currently applies to live H.264 and H.265 video, with potential future support for audio. It is designed to work in conjunctio...
