Patent ID: 8230226

Claim:
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 to form a second watermarked compressed digital media data file, the modifying combining at least a portion of the unwatermarked compressed digital media data file with at least a portion of the first watermarked compressed digital media data file to form the second watermarked compressed digital media data file; wherein modifying the first watermarked compressed digital media data file comprises: generating the transaction identifier, the transaction identifier indicative, at least in part, of an association of the first watermarked compressed digital media data file with a specific transaction; converting the transaction identifier into a binary codeword; and combining at least a portion of an unwatermarked compressed digital media data file with at least a portion of the first watermarked compressed digital media data file; wherein the binary codeword defines at least a portion of the unwatermarked compressed digital media data file and at least a portion of the first watermarked compressed digital media data file to be combined.
