摘要： A method and system of detecting colluders conducting a collusion attack including a minority-type collusion attack on a digital product includes the generation of codewords used as watermarks in the digital product. The inner code of the codewords is generated using permutations of rows in a Hadamard matrix and concatenating them together. A typical outer code of the codeword is the Reed Solomon code. An adaptive detector is able to accurately detect one of three or more colluders of a minority-type attack. Prior art schemes using an error correcting code-based watermarking mechanism with an inner code fail to detect colluders with a minority-type collusion attack which includes three colluders.

摘要： A method comprises accessing changes which can be watermarks in a list for coded data, the changes having an syntax element, an original value and an candidate alternative value; determining for a subset a group of compliant changes from the changes, the complaint changes being compliant with a coding protocol such as a CABAC encoding protocol; and selecting for the subset only compliant changes that result in the subset having only one candidate alternative value for each syntax elements and result in only compliant changes also meeting at least one performance criterion. The method can include determining fidelity, recoverability, or robustness of the watermarks and removing or preventing watermarks from being in the subset based on the fidelity, recoverability, or robustness, wherein fidelity, recoverability, and robustness are performance criteria. The method can include determining at least two performance values for the watermarks, determining some collective metric of the at least two performance values, and removing or preventing watermarks from being in the subset based on the same collective metric.

摘要： A method of providing CABAC compliant changes such as watermarks comprises accessing encoded data such as video which comprise at least two blocks; creating or accessing a list of changes to the encoded data that include a direct change to a block; determining motion character or motion vector differential of non-immediate block, non-immediate blocks being adjacent to an immediate block that are immediately adjacent to the block; determining change to the immediate block based on original motion character of the block and the non-immediate block and the motion character of the block that would result from the application of the change; storing the change to the list if the change does not cause a difference to the immediate block; and evaluating other potential changes if other potential changes are available, wherein the other potential changes are subjected to the same process steps as the direct change.

摘要： Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering watermarking information from data. In one implementation, a coded bitstream is modified to allow for the application of a watermark to the coded bitstream without changing the coding of any other syntax elements in the bitstream. This is performed by identifying conditions necessary to change a coded syntax element without disrupting the interpretation of subsequent coded elements. The coded syntax element is replaced with another coded value if the modified value generates the same decoding variables as the original value would have generated. Particular implementations focus on syntax elements coded using entropy coding, including, for example, Context-based Adaptive Binary Arithmetic Coding (CABAC). Regardless of the type of coding or watermarking, various implementations may provide for recovering watermarking information. Particular implementations recover watermarking information using detection data and feature information.

摘要： A method for detecting and selecting watermarking in video coding is provided that comprises accessing a list of possible watermarks; generating propagation maps of modifications to the video that would be caused by applying the respective watermarks; generating a detection region responsive to each respective propagation map that includes blocks within the propagation map that collectively rank highest with respect to a selected detection criteria compared to each other region within the propagation map; selecting a threshold metric for evaluating detection regions; and removing watermarks from the list responsive to a comparison of their detection regions with the threshold metric.

摘要： An apparatus and method for encoding and decoding a broadcast data stream that includes encrypted advertisement cue messages. The encrypted advertisement cue message data representing a advertisement to be inserted into a stream and data representing an insertion time within said broadcast data stream that is associated with said advertisement. The advertisement cue messages are encrypted and encrypted using a encryption technique. The encrypted advertisement cue message masks the insertion time for the advertisement and prevents automatically skipping of the advertisement data.

摘要： Systems and methods of utilizing communications networks and multivariate analysis to predict or recommend optimal products from a predefined population of commercially available products are disclosed. The recommendations are based on intelligence contained in processing elements and subjective and/or objective product information received from consumers or input to the systems as part of their initial setup. The output of the systems comprise sets of products that they predict the consumer will prefer and/or perform well for the problem or concern identified by the consumer. The performance and preference predictions are a function of consumer problems and product responsiveness patterns. Objective product information is generally obtained with diagnostic instruments. Data measured with the diagnostic instruments may be communicated to the data processing portions of the invention via the Internet. The outputs of the data processing portion of the system may be presented to consumers via the Internet as well.
