Abstract
Unlike the conventional approach where a forensic watermark is inserted before a work of media is encoded and then distributed, a technology, described herein, applies a forensic watermark to a work after or as the work is decoded by those receiving the work via a distribution. Consequently, this technology facilitates effective and efficient distribution of works of media by applying the forensic watermark to works after and/or as it is decoded.
Claims24
A system comprising:
- a decoder configured to decode encoded media;
- a watermark inserter coupled to the decoder and configured to obtain forensic data, generating a watermark in association with the forensic data, and inserting the watermark to the decoded encoded media.
A system comprising:
- a means for decoding encoded media;
- a means for obtaining forensic data;
- a means for generating a watermark in association with the forensic data;
- a means for inserting the watermark to the decoded encoded media.
A method comprising:
- decoding encoded media;
- obtaining a first unique identifier (ID);
- generating a watermark in association with the first unique ID;
- adding the watermark to the decoded encoded media.
A processor-readable program product having processor-executable instructions that, when executed by a processor, perform the acts comprising:
- decoding encoded media;
- obtaining forensic data;
- generating a watermark in association with the forensic data;
- inserting the watermark to the decoded encoded media.
