Private Stream Access & Policy Guard

Audit and enforce restricted stream settings. Test viewer access against cryptographic HMAC signatures, geofence rules, token leases, and dynamic watermarking.

Restricted Streaming Architecture & Policy Guidelines

1. HMAC Token Verification

Private streams restrict egress by appending cryptographically signed tokens (exp, uid, sig). Edge CDN workers (Cloudflare Workers, CloudFront Functions) calculate HMAC-SHA256(secret, URI + expiration + uid) in sub-millisecond execution to reject unauthenticated playback requests before fetching video manifests.

2. Zero-Trust Dynamic Watermarking

When authorized viewers stream high-value content, client-side or server-side transcoder watermarking burns the unique session_id and client IP onto intermediate frames at randomized coordinate offsets. This renders screen recordings and unauthorized restreaming instantly attributable.

3. Geo & Domain Isolation

To block web embed piracy, validate both Origin and Sec-Fetch-Site headers against strict corporate domains. Pair with CDN-level IP-to-Country lookups to enforce distribution rights and prevent cross-border compliance penalties.
