Abstract

A method of watermarking digital content by a trusted third party, comprising: capturing an image of the digital content; embedding a first watermark into the digital content, wherein the presence of the first watermark indicates the owner of the digital content; embedding a second watermark into the digital content, wherein the presence of the second watermark indicates integrity of the digital content; storing the digital content in a repository.
