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 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.
