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： The invention relates to a method for watermark embedding in multi views video comprising a plurality of views captured with a plurality of cameras comprising for each view a step of projecting the view onto a domain invariant to the plurality of views and to intermediate synthesized view, which depends on the locations, orientations, and intrinsic parameters of the cameras, resulting into an invariant vector; a step of applying a watermarking algorithm to the invariant vector resulting into a watermarked invariant vector; and a step of modifying the view to obtain a watermarked view, wherein said watermarked view when projected onto the invariant domain results into the watermarked invariant vector.The invention also relates to a method for watermark detection in a rendered view comprising a step of projecting the rendered view onto an invariant domain to the plurality of views resulting into an invariant rendered vector; a step of applying a watermark detection algorithm to the invariant rendered vector in order to assess the presence of a watermark.

摘要： A 3D object is protected by a first device that receives the 3D object, permutes the coordinates of at least one dimension of at least some of the points of the 3D object to obtain a protected 3D object, and outputs the protected 3D object. The coordinates of the dimensions are preferably permuted independently of the permutations of the other dimensions. The protected 3D object is unprotected by a second device (140) by receiving the protected 3D object, permuting the coordinates of at least one dimension of at least some the points of the protected 3D object to obtain an unprotected 3D object, and outputting the unprotected 3D object. Also provided are the first device, the second device and computer readable storage media.

摘要： A method for classifying projection recaptures is disclosed. A copy of a video content is classified as recorded from the digital projection of the video content, or as recorded from the projection of the celluloid film print of the video content by an automated method comprising classifying as a function of at least one feature extracted from a digital representation of the copy, among (i) spatial illumination uniformity; (ii) on-screen vertical stability; and (iii) temporal illumination pulse.
