    Abstract: The implementations of digital watermarks can be optimally suited to particular transmission, distribution and storage mediums given the nature of digitally-sampled audio, video and other multimedia works. Watermark application parameters can be adapted to the individual characteristics of a given digital sample stream. Watermark information can be either carried in individual samples or in relationships between multiple samples, such as in a waveform shape. More optimal models may be obtained to design watermark systems that are tamper-resistant given the number and breadth of existent digitized sample options with different frequency and time components. The highest quality of a given content signal may be maintained as it is mastered, with the watermark suitably hidden, taking into account usage of digital filters and error correction. The quality of the underlying content signals can be used to identify and highlight advantageous locations for the insertion of digital watermarks. The watermark is integrated as closely as possible to the content signal, at a maximum level to force degradation of the content signal when attempts are made to remove the watermarks.

    Abstract: Disclosed herein are methods and systems for transmitting streams of data. In one embodiment, a method comprises the steps of: receiving a stream of data; organizing the stream of data into a plurality of packets; generating a packet watermark associated with the stream of data; combining the packet watermark with each of the plurality of packets to form watermarked packets; and transmitting at least one of the watermarked packets across a network. The present invention also relates to: receiving at least one packet that has been transmitted across a network; analyzing at least one packet for a watermark; and authenticating the at least one packet using at least a portion of the watermark. The present invention also relates to generating packet watermarks and packet watermark keys.

    Abstract: The present invention relates to methods for protecting a data signal using the following techniques: applying a data reduction technique to reduce the data signal into a reduced data signal; subtracting the reduced data signal from the data signal to produce a remainder signal; embedding a first watermark into the reduced data signal to produce a watermarked, reduced data signal; and adding the watermarked, reduced data signal to the remainder signal to produce an output signal. A second watermark may be embedded into the remainder signal before the final addition step. Further, cryptographic techniques may be used to encrypt the reduced data signals and to encrypt the remainder signals before the final addition step.
