摘要： Sparse signal modulation schemes encode a data channel on a host image in a manner that is robust, flexible to achieve perceptual quality constraints, and provides improved data capacity. The host image is printed by any of a variety of means to apply the image, with sparse signal, to an object. After image capture of the object, a decoder processes the captured image to detect and extract data modulated into the sparse signal. The sparse signal may incorporate implicit or explicit synchronization components, which are either formed from the data signal or are complementary to it.

摘要： This disclosure describes methods for using embedded auxiliary signals in documents for copy detection and other applications. In an application, the auxiliary signal is formed as an array of elements selected from a set of print structures (106) with properties that change differently in response to copy operations. These changes in properties of the print structures that carry the embedded auxiliary signal are automatically detectable. The extent to which the auxiliary data is detected forms a detection metric used in combination with one or more other metrics to differentiate copies from originals. Robust and fragile watermarks are used in Image Replacement Documents for a variety of applications. Digital watermarks act as on-board mediators in authentication of a variety of printed documents. Finally, digital watermarks are used to help manage quality of the scanners used in imaging systems.

摘要： This disclosure describes novel methods for generating unique copies of content. One method combines the functions of the master copy and unique copy watermarks. In particular, the method generates a unique copy by varying the manner in which the master copy watermark is embedded in unique copies of a content item. In one embodiment, the master copy watermark is repeated within the content item and its location is varied in a unique pattern that comprises the unique copy watermark. The unique copy is generated by producing a copy in which master copy watermarks are embedded in a unique pattern. For instance in one embodiment, the locations of the master copy watermarks in the content item are represented as a vector of delta values in which each delta value corresponds to the distance between a corresponding instance of the master copy watermark, and a neighboring instance of the master copy watermark. This vector is stored in a transaction record in association with transaction information, such as information identifying the master copy and information associated with the unique copy. Other ways of representing the unique pattern of attributes of the master copy watermark are also possible. In other embodiments, properties of the master copy watermark other than its location are varied through the content. The unique copy watermark is conveyed in the vector of deltas in these properties of the master copy watermark. Some examples of these properties of the master copy watermark signal include phase characteristics (e.g., the phase shift of a watermark carrier signal), frequency magnitude characteristics, etc. These properties are varied in a manner that does not alter the information carried in the master copy watermark. However, it does provide a variation that creates a unique copy, and the unique copy watermark is conveyed in this variation. The variation in location of the instances of the master copy watermark can be in different domains, such as a spatial domain, a time domain, a time-space domain, a transform domain (including frequency transform domains), a compressed domain, etc.

摘要： The disclosure relates to a smartphone-based virtual wallet, that manages payment options available to a user. One claim recites a portable device comprising: a touch screen display; a microphone for capturing ambient audio; memory for storing an image; and one or more processors. The one or more processors are configured for: generating copies of the stored image; obtaining a payload corresponding to financial information; providing the payload to an erasure code generator, in which the erasure code generator produces a plurality of outputs; embedding one of the plurality of outputs in a copy of the stored image and proceeding with embedding until each of the plurality of outputs is so embedded in a copy of the stored image, in which the embedding utilizes digital watermarking; causing the touch screen display to display embedded image copies so as to cause a static image display effect, the displayed embedded image copies being displayed by the portable device in response to a user input to enable a financial transaction. A great variety of other features, arrangements, combinations and claims are also detailed.

摘要： Audio signal processing enhances audio watermark embedding and detecting processes. Audio signal processes include audio classification and adapting watermark embedding and detecting based on classification. Advances in audio watermark design include adaptive watermark signal structure data protocols, perceptual models, and insertion methods. Perceptual and robustness evaluation is integrated into audio watermark embedding to optimize audio quality relative the original signal, and to optimize robustness or data capacity. These methods are applied to audio segments in audio embedder and detector configurations to support real time operation. Feature extraction and matching are also used to adapt audio watermark embedding and detecting.

摘要： Signal processing devices and methods estimate transforms between signals using a least squares technique. From a seed set of transform candidates, a direct least squares method applies a seed transform candidate to a reference signal and then measures correlation between the transformed reference signal and a suspect signal. For each candidate, update coordinates of reference signal features are identified in the suspect signal and provided as input to a least squares method to compute an update to the transform candidate. The method iterates so long as the update of the transform provides a better correlation. At the end of the process, the method identifies a transform or set of top transforms based on a further analysis of correlation, as well as other results.
