Abstract

The present invention relates to methods and apparatus for transfer of editable digital content. A first entity (60) stores content data (C1 ') comprising digital content embedded with a first watermark (W1 '). The first entity transmits structure data (S(c1 ')) to a transfer control entity (50), the structure data being indicative of the structure of at least a portion of the content data. The transfer control entity selects a transmission key (k1) in dependence upon the structure data, and transmits the transmission key to the first entity. The first entity applies the transmission key to the content data to remove the first watermark from the digital content and encrypt the digital content. The first entity transmits the encrypted digital content (E(c1 ')) to a second entity (70). The transfer control entity transmits a receive key (k2) to the second entity. The second entity applies the receive key to the encrypted digital content to generate decrypted data (c2) comprising the decrypted digital content embedded with a second watermark (w2).
