    摘要: The invention relates to a method for decoding a watermark embedded in a video comprising blocks of samples representative of the video comprising the steps of determining in the video a location of a watermarked block; determining a location for each reference block among a plurality of reference blocks wherein a reference block is associated to a watermark value among a plurality of watermark values; comparing the watermarked block with each reference block; and identifying watermark value for the watermarked block from the results of the plurality of comparison. The method is remarkable in that each reference block is equally located in the video, for instance the pirated video, so that the plurality of comparisons between the watermarked block and each reference block is performed among the same video.

    摘要: An ionic probe is provided according to the invention. The ionic probe includes an active electrode configured to generate a measurement signal for an external test fluid, a first reference electrode configured to generate a first reference signal, and an at least second reference electrode configured to generate at least a second reference signal. The measurement signal is compared to the first reference signal and the at least second reference signal in order to determine an ionic measurement of the external test fluid.

    摘要: A method for preventing the bypassing of watermark embedding in a bit-stream representative of audio/video data is disclosed. The method is remarkable in that it comprises a step of corrupting the bit-stream wherein original blocks in the bit-stream are replaced by corrupted blocks producing a non-compliant bit-stream; and a step of repairing the corrupted bit-stream by replacing each corrupted blocks, wherein at least one corrupted block is replaced by a watermarked block and at least one corrupted block is replaced by an original block, producing a compliant repaired and watermarked bit-stream. A device for watermarking and repairing a corrupted bit-stream and to a device for preparing a corrupted bit-stream, wherein the original bit-stream is representative of audio/video data are further disclosed.

    摘要: A unitary ionic probe is provided. The unitary ionic probe includes a substantially elongate body including a central axis (AA), a proximal end, and a distal end. The unitary ionic probe further includes an active ion sensitive region that is located on and bonded into an exterior of the elongate body in a region of the proximal end and an active electrode in ionic communication with the active ion sensitive region. The unitary ionic probe further includes a reference ion sensitive region that is located on and bonded into the exterior of the elongate body and is spaced-apart from the active ion sensitive region and a reference electrode in ionic communication with the reference ion sensitive region.
