METHOD AND SYSTEM FOR PROVIDING IMAGE PROCESSING TO TRACK DIGITAL INFORMATION
摘要
An approach for tracking documents using image processing is disclosed. Auxiliary information corresponding to compressed digital information is extracted. The auxiliary information is used to output text lines, which undergo a hash function (e.g., checksum operation). In this manner, individual hash values are generated, as well as an overall hash value of the entire file of text lines. A reference set of hash values are maintained to identify other compressed digital information.
