Abstract (en)
[origin: WO2004015581A1] Valued content (200, 300, 400, 500) in a digital form includes a digital file (212) and a digital string (214) that is provided by a purchaser to a provider system (222, 322, 422, 522) of the valued content. The digital string has a latent value to the purchaser, and the provider system embeds the digital string in the digital file before the valued content is conveyed to the purchaser. An embedded digital string (226) is formed creating an embedded digital file (212').
