Advanced watermarking system and method

摘要

A method, computer program product, and computing device for obtaining an uncompressed digital media data file. One or more default watermarks is inserted into the uncompressed digital media data file to form a watermarked uncompressed digital media data file. The watermarked uncompressed digital media data file is compressed to form a first watermarked compressed digital media data file. The first watermarked compressed media data file is stored on a storage device. The first watermarked compressed media data file is retrieved from the storage device. The first watermarked compressed digital media data file is modified to associate the first watermarked compressed digital media data file with a transaction identifier to form a second watermarked compressed digital media data file.

1. A method comprising:
obtaining an uncompressed digital media data file; inserting one or more default watermarks into the uncompressed digital media data file to form a watermarked uncompressed digital media data file; compressing the watermarked uncompressed digital media data file to form a first watermarked compressed digital media data file; storing the first watermarked compressed media data file on a storage device; retrieving the first watermarked compressed media data file from the storage device; compressing the uncompressed digital media data file to form an unwatermarked compressed digital media data file; and modifying the first watermarked compressed digital media data file to associate the first watermarked compressed digital media data file with a transaction identifier indicative, at least in part, of an association of the first watermarked compressed digital media data file with a specific transaction, to form, via realtime processing at a time of the specific transaction, a second watermarked compressed digital media data file, wherein the transaction identifier comprises a binary representation selected from the group consisting of a bitpattern, a segment map, and a binary codeword.
