C2PA Video 
Signature Service

C2PA signature management for a video stream is more complex and demanding than for a document or an image, and EZDRM has architected its new Video Signature Service in a manner that makes it highly scalable and very low latency. Operating in conjunction with the recently introduced EZDRM Provenance Signature Vault, EZDRM is demonstrating how the value of C2PA can be effectively applied to live event video, offering a range of security benefits to both providers and consumers.

Like other EZDRM microservice offerings, the Video Signature Service is meticulously designed to seamlessly integrate with existing streaming workflows. This service facilitates comprehensive traceability of streaming content by securely managing C2PA content attribution data for large-scale service deployments. Importantly, in a market where, for example, sports-related content is a significant revenue driver for streaming services, EZDRM is offering thought leadership in the application of C2PA to live streaming integrity, and providing a testbed for the approach that C2PA is taking in its standardization efforts.

By leveraging both manifest-based and hosted C2PA metadata, EZDRM enables player devices to initiate media streaming with low startup times, without needing to wait for full provenance verification. The verification of the signature chain and authenticity can occur in parallel to media consumption, enabling seamless user experiences without compromising on trust. This architecture separates content validation logic from playback logic, reducing latency and improving scalability. It also opens the door to real-time integrity monitoring and dynamic trust scoring, making it ideal for both live streaming and on-demand scenarios where playback speed and authenticity are equally critical.
