Post decode watermarking of media |
摘要 |
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.
