IPC: H04N7/26
Filed: 2002-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a watermarking technology that minimizes the probability of false alarms and the probability of misses. SOLUTION: A non-local QIM(quantity index modulation) watermarking architecture 100 has a content producer/provider 122, that produces original contents and distributes the content over a network 124 to a client 126. The content producer/provider 122 has a watermark embedding system 132 for signing the digital signals with a watermark, that uniquely identifies the content as original. The watermark embedding system 132 applies the watermark to a digital signal from a content storage 130. Typically, the watermark identifies the content producer 122, providing a signature that is embedded in the signal and cannot be removed cleanly.
