摘要： The invention provides a method for authenticating a physical object (OBJ) using a first helper data (Wl) and a first control value (Vl) associated with a reference object. The method comprises a step to generate a first property set (Sl) using a noise compensating mapping (NCM) on information derived from the first helper data (Wl) and a metric data (Y) associated with the physical object, and a step to establish a sufficient match between the physical object and the reference object using the first property set (Sl) and the first control value (Vl). The method further comprises a step to generate an update data (WUPD) for updating the first helper data (Wl) using the first helper data (Wl), the first property set (Sl) and the metric data (Y). Also provided is a client terminal configured to carry out the method.

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 present invention relates to a method, a device and a system for preventing unauthorized introduction of content items in a network containing compliant devices. A basic idea of the present invention is to provide a CA (206) with a fingerprint of a content item to be introduced in a network at which the CA is arranged. Further, the CA is provided with an identifier of a content introducer (201), which introduces the particular content item in the network. The CA compares the fingerprint to a predetermined set of fingerprints, and content item introduction is allowed if the content itemfingerprint cannot be found among the fingerprints comprised in the set. On introduction of the content item, the CA generates a watermark identifier, a watermarking key and a signed content ID certificate comprising at least said fingerprint and a unique content identifier for the content item and the identifier of the content introducer. Then, the watermark identifier is inserted in the content item by means of the watermarking key.

摘要： The invention relates to a method of checking the correct operation of a signal transformation wherein an input signal is transformed into an output signal. The method comprises: deriving a first robust feature from the input signal; deriving a second robust feature from the output signal; comparing said first and second robust features; in case of sufficient similarity, concluding a correct operation of said signal transformation, and in case of insufficient similarity, concluding a false operation of said signal transformation. In a special embodiment, the method is applied wherein the first robust feature is embedded in the input signal through watermark technology, the thus obtained signal being transmitted to a receiver so as to retrieve an output signal corresponding to said input signal.

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： Identification of a digital media sequence is performed by an encoding and a decoding process. A sequence is received and its digital fingerprint is computed. A database lookup based on the fingerprint produces one or more matches that all resemble the computed fingerprint to a certain degree. If there is more than one match, at least one attempt is made to detect a watermark in the sequence. If a watermark is found, at least part of the watermark is extracted and used to select one of the matches among the sequences that resemble the media sequence to be identified.

摘要： A method for configuring a biometric template protected authentif ication system, in which the desired classification threshold (T) is first selected to optimize the trade-i off between FAR and FRR of the system, and then the ECC used in the authentif ication process is chosen such that the number (b) of errors which can be corrected thereby is equal to or greater than the selected classification threshold. During authentif ication, the number (b) of errors in a first codeword derived from biometric data associated with a physical object is determined and used in the decision process to accept or reject authentif ication.
