Abstract
A method for applying a digital watermark to a content signal is disclosed. In accordance with such a method, a watermarking key is identified. The watermarking key includes a binary sequence and information describing application of that binary sequence to the content signal. The digital watermark is then encoded within the content signal at one or more locations determined by the watermarking key.
Claims23
A method for applying a digital watermark to a content signal, comprising the steps of:
- identifying a watermarking key comprising a binary sequence and information describing application of the binary sequence to the content signal;
- encoding the digital watermark within the content signal at one or more locations determined by the watermarking key;
- and
- generating a key pair associated with the watermarking key.
A digital watermarking system for encoding and decoding a digital watermark within a content signal, comprising a digital watermark encoder and a digital watermark decoder, wherein said digital watermark encoder and said digital watermark decoder are configured to respectively encode and decode a digital watermark using (1) a watermarking key comprising a binary sequence and information describing application of the binary sequence to the content signal and (2) a key pair associated with the watermarking key.
A method for applying a digital watermark to a content signal, comprising the steps of:
- identifying a watermarking key comprising a binary sequence and information describing application of the binary sequence to the content signal, wherein the application of the binary sequence to the content signal is based on characteristics of the content signal;
- and
- encoding the digital watermark within the content signal at one or more locations determined by the watermarking key.
