Abstract

A method for mapping a work (e.g., a picture, a document or the like) comprising a large number of bytes into a relatively small bit string (2) to facilitate copy protection. The technique creates a first string (2) from the work with the property that if one modifies the work by some given degree (e.g., through intentional variation or perhaps merely through aging), a second string (3) (generated by the inventive technique) and associated with the modified work is not meaningfully distinct from the first string (2). When applied through the algorithm, works that are similar result in the same or similar strings (5). As a result, an owner of the content sought to be protected may apply the algorithm to copies of the work or copy protection purposes.
