摘要： Methods and systems for time-frequency domain watermarking of media signals, such as audio and video signals. An encoding method divides the media signal into segments, transforms each segment into a time-frequency representation, and computes a time-frequency domain watermark signal based on the time frequency representation. It then combines the time-frequency domain watermark signal with the media signal to produce a watermarked media signal. To embed a message using this method, one may use peak modulation, pseudorandom noise modulation, statistical feature modulation, etc. Watermarking in the time-frequency domain enables the encoder to perceptually model time and frequency attributes of the media signal simultaneously. A watermark decoder uses a calibration signal to detect the watermark signal in a potentially distorted version of the watermarked signal. The calibration signal may also be used to determine the watermark's alignment and scaling. After compensating for the alignment and scaling, a watermark reader extracts an embedded message from a time frequency representation of the media signal.

摘要： A media object authentication system uses layers of security features based on digital watermarks embedded in media objects. The system generates a first digital watermark with a message payload carrying data about the object, such as a hash of text data printed on the object. The first digital watermark is combined with a content signature derived from features of the media object, such as frequency domain attributes, edge attributes, or other filtered version of the media signal (e.g., image photo on a secure document) on the media object. This combination forms a new digital watermark signal that is embedded in the host media object. To verify the object, the digital watermark payload is extracted and compared with the data about the object. The combined digital watermark and content signature is also evaluated to authenticate the media signal on the media object.

摘要： A method is provided for authenticating a media signal and related software, systems and applications. A digital watermark is embedded in the media signal. A metric is calculated for the digital watermark as embedded in the media signal. The resulting metric is then embedded in the media signal with the digital watermark. To detect a potential alteration, a detector computes the metric for a potentially corrupted version of the embedded media signal. The detector then compares its computed metric to the embedded metric to detect whether the alteration has occurred.

摘要： The present invention relates to digital watermarking. In one implementation, a system is provided to read a digital watermark from digital imagery which includes data representing a number of pixels. Each pixel of the number of pixels is defined by a set of values representing color components of the particular pixel. The digital watermark is embedded in the digital imagery through modifications to at least some data representing the digital imagery. The system includes a filter to calculate values of pixels along a preferred projection axis, the preferred projection axis corresponds to a direction of embedding determined based on color characteristics of at least some pixels associated with the digital imagery; and a digital watermark reader which operates on values calculated by the filter. Other implementations are provided as well.
