IDMark Turns Two Video Streams into a Leak Trail

Field notes

IDMark prepares two streams with different encoding parameters, then builds a viewer-specific playlist by choosing segments from Stream A or Stream B to encode a digital signature. The page says this avoids generating a complete unique stream for every viewer and works across delivery formats including HLS, DASH, RTMP, WebRTC, SRT, and SDI. Deployment is offered in cloud or on the client’s own servers, with the latter keeping data and keys inside the client’s infrastructure.
