The present disclosure provides a method of watermarking digital media for subsequent decoding. The method includes receiving a secure content package comprising digital audiovisual content, source entity information, content annotations, and digital signatures. The package is validated using public-key cryptography. A content identifier is generated and embedded as a watermark into the digital audiovisual content. The watermark is configured to be machine readable and visually inconspicuous. A content database entry is recorded in a remote database, retrievable using the content identifier and comprising the content annotations and source information. The watermarked digital audiovisual content is stored and transmitted to the media source. The method may further include generating and storing content hashes for future authentication comparisons.
