Abstract: A portable level sensor for a flexible bag for collecting a fluid and/or a solid, and a system and method for sensing the content level of a flexible bag using the portable level sensor. The sensor comprises a flexible resistor element with an electrical resistance that changes in dependence upon its degree of flexing, means for attaching the resistor element to an outside surface of the flexible bag and means for periodically polling the electrical resistance of the resistor element and transmitting to a receiver a signal which varies in dependence on the said electrical resistance.

Abstract: 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.

Abstract: A method comprises accessing encoded video data; accessing a list of watermarks to the encoded video data; determining syntax elements for current blocks of video data and syntax elements of currents blocks with the watermarks; removing watermarks that cause visible artifacts based on differences in the syntax elements between the current blocks and current blocks with watermarks, thereby creating filtered list of acceptable watermarks. The method can further include determining coding variable ranges for the current block and current block with watermarks from the list; comparing the coding variable ranges for the current blocks and current blocks with watermarks from the list; and filtering out watermarks that yield coding variable ranges outside the coding variable ranges of the current blocks.

Abstract: 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.

Abstract: A method comprises receiving original encoded video stream as one input, accessing encoded data divided into slices which are further divided into blocks, receiving the list of possible changes or watermarks as another input, accessing at least one block, decoding each slice, setting down each slice, extracting from the list those changes that apply to the at least one block, and constructing propagation maps from inter-prediction or intra-prediction using changes for the at least one block. The method can further comprise decoding luminance data using the propagation maps, comparing the luminance data to a fidelity threshold, and applying possible changes or watermarks to those not exceeding the fidelity threshold.

Abstract: 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.

Abstract: A method comprises providing a change to apply to video; dividing video into blocks; creating propagation map which captures only specific changes to blocks that would be changed by the application of the change; evaluating the change based on a luminance criterion as being a perceptible change or an imperceptible change; for propagation maps of an imperceptible change, storing the propagation map to a list, wherein the propagation map is the principle data structure to be applied to the video. The propagation map can be created by using motion vector changes associated with the change.

Abstract: 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.

Abstract: Various implementations are provided for, for example, determining watermarking data, performing the watermarking, and processing watermarked data. At least one implementation watermarks AVC bitstream that uses CAVLC entropy coding. The watermarking data may be determined in a pre-processing stage and stored for later use in watermark a bitstream. One method accesses variable-length encoded data including an encoding of information identifying an actual reference used to predictively encode an image. The encoding of the information has a particular value. The method determines an alternative value that is different from the particular value, such that the alternative value is an encoding of alternative information that identifies a different reference from the actual reference. The alternative value is for use in watermarking the variable-length encoded data.
