摘要： The present invention relates to methods and apparatus for transfer of editable digital content. A first entity (60) stores content data (C1 ') comprising digital content embedded with a first watermark (W1 '). The first entity transmits structure data (S(c1 ')) to a transfer control entity (50), the structure data being indicative of the structure of at least a portion of the content data. The transfer control entity selects a transmission key (k1) in dependence upon the structure data, and transmits the transmission key to the first entity. The first entity applies the transmission key to the content data to remove the first watermark from the digital content and encrypt the digital content. The first entity transmits the encrypted digital content (E(c1 ')) to a second entity (70). The transfer control entity transmits a receive key (k2) to the second entity. The second entity applies the receive key to the encrypted digital content to generate decrypted data (c2) comprising the decrypted digital content embedded with a second watermark (w2).

摘要： A secure forensic watermarking system is disclosed that distributes the same encrypted content to all users. The decryption key is different for each user, so that the decrypted content differs slightly from the original, i.e. is watermarked. Forensic tracking is possible by distributing unique decryption keys to individual users. The invention allows a forensic mark to be securely embedded in the compressed domain signal. In an embodiment of this invention, the content (x) and an encryption sequence (r) are entropy encoded using a homomorphic Huffman table. A homomorphic Huffmann table is a table H having the property that there exists an operation f() such that H-1 ( f (H(a),H(b))) = a + b.

摘要： Disclosed are a method and a system for secure watermark embedding in a server-client configuration (60,70). The method comprises encrypting (210) the data signal (x) and generating (240) a decryption key wherein a watermark (W i ) is included. The client decrypts (420) the encrypted data signal in order to obtain a watermarked data signal (x w ). In accordance with the invention, the encryption mechanism and decryption key are made dependent on a perceptual mask (m 1 ,m 2 ) so as eventually make the embedded watermark more robust.

摘要： The invention relates to a method of searching for a watermark in a data signal, and to a watermark detector, such as a copy-control watermark detector. The search is conducted in order to find a watermark in content which possibly has been attacked and/or altered. The search is conducted by the steps of determining or setting a search space for the data signal, selecting a subspace of the search space, and searching for the presence of the watermark in the subspace. The subspace may be selected from a multitude of regions, the selection e.g. being based on a deterministic or probabilistic function.

摘要： The invention relates to a watermark generation method for generating watermarks to be embedded in digital media, where said watermark is generated by combining at least two watermark patterns from a set of watermark patterns. The set of watermark patterns are divided into at least two subsets of watermark patterns, and the subsets are hierarchically related and the watermark patterns in said watermark are directly related watermark patterns. Directly related means that the watermark patterns are related like parent and child in a hierarchical structure e.g. a tree structure. Further, the invention relates to an apparatus adapted to generate watermarks to be embedded in media.

摘要： A method and a system for modifying a bitstream signal for enabling collusion resistant bitstream watermarking. The method comprises dividing a bitstream spectral signal X[k] of the bitstream signal bx into a first signal (302) and a second signal (304); multiplying the first signal (302) by a first modification signal (306) and outputting a modified first signal (314); performing a transform operation on said second signal (304) for obtaining a transformed second signal (308); multiplying said transformed second signal (308) by a second modification signal (310) and outputting a second modified signal (312); subtracting said second modified signal (312) from said first modified signal (314) and outputting a modified bitstream spectral signal X'[k] suitable for obtaining a modified bitstream signal b'x of said bitstream signal bx. Thus an efficient manner of applying a collusion resistant property for already encoded contents is provided.

摘要： The invention concerns a method of bit stream watermarking in a tandem coding system (300). The method involves arranging for the system (300) to comprise a series of stages including a first quantizing unit for processing an input signal to generate a first intermediate signal, a combining unit for embedding a watermarking signal into the intermediate signal to generate a second intermediate signal, and a second quantizing unit for processing the second intermediate signal to generate a watermarked output signal. The first quantizing unit to arranged to include a unit for predicting distortions arising in subsequent stages of the system (300) and generating one or more corresponding quantization noise reduction parameters. Moreover, the system (300) is operable to apply the one or more reduction parameters in at least one of the subsequent stages for reducing noise and/or distortion arising within the system (300).

摘要： The present invention relates to methods, devices, a media signal and a recorded medium for watermarks embedded in the sub-band domain of compressed media. Watermarks (w[n]) are embedded into the sub-band signals (xi-1[n], xi[n],xi+1[n]) of at least one selected sub-band of a compressed bit-stream (bk) using a watermark inserting unit (18). In this way there is no need to fully decode and re-encode the media signal for embedding the watermark. The watermark is embedded in selected sub-bands (e.g. sub-bands 7-15 of 32). In a preferred embodiment, the selected sub-bands are upsampled before embedding and downsampled therafter to avoid aliasing. The invention also allows embedding multiple watermarks in different sub-bands (e.g. one watermark in sub-bands 7-11, and a different watermark in sub-bands 12-16).
