SYSTEM AND METHOD FOR PARTIAL URL SIGNING WITH APPLICATIONS TO DYNAMIC ADAPTIVE STREAMING

A partial URL signing scheme for controlling access to content provided in adaptive streaming such as DASH is disclosed herein. Partial URL signing and verifying algorithms act as extensions to existing URL/URI signing techniques (e.g., IETF URI Signing). Partially signed URLs are signaled in an MPD and may take the form of a prefix, a suffix, or a substring of a URL. Individual segments of the content are requested by the client using URLs constructed based on a URL segment template with partial URL signing information provided as a query parameter for verification.
