摘要： A removable security device configured to prevent unauthorized exploitation of files, connectable with a host device, the removable security device comprising a central processor, an operating system, a graphic processor, memories and a communication link configured to exchange data with the host device. The removable security device further comprises an identification module for verifying conformity of at least one user credential received from the host device via the communication link. The operating system enables through a remote desktop agent remote access to at least one file and executes a file processing application with the at least one file. The operating system, the remote desktop agent and the file processing application are stored in a non-volatile memory of the removable security device. The graphic processor generates displayable frames corresponding to the execution of the application with the file. A watermarking module coupled to the graphic processor inserts additional data into the displayable frames, said additional data forming a watermark generated on all or part of the displayable frame. The additional data allows retrieving at least the identifier of the removable security device. The communication link transmits the watermarked displayable frames to the host device.

摘要： A media stream is delineated into multiple fragments. Different watermark variants of individual fragments are generated. Particular sequences of watermark variants are selected for particular clients and maintained in a user access database. Analyzing media streams allows determination of the sequences of watermark variants and identification of particular clients intended to receive the media streams. Fragments can continue to be cached efficiently and unique watermarks need not be generated for each individual client.

摘要： The present invention relates to methods and apparatus for transfer of digital content. A method of transferring digital content from a first entity (60) to a second entity (70) includes a transfer control entity (50) transmitting a transmission key k 1 [n] to the first entity. The first entity applies the transmission key to digital content, to encrypt the digital content. The first entity transmits the encrypted digital content to the second entity. The transfer control entity transmits a receive key k 2 [n] for receipt by the second entity. The second entity applies the receive key to the encrypted digital content to generate decrypted data comprising the decrypted digital content embedded with a watermark w[n]. The transfer control entity transmits a degraded version w'[n] of the watermark to an entity for watermark detection.

摘要： Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of th content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.

摘要： A multiple party system for distributing content. In one embodiment four parties are involved in the system: a consumer, a service provider, an authenticator, and a content provider. The distribution of content from the content provider to the consumer is carried out using a predefined protocol, mutating Ids, watermarks, and licenses. The authenticator controls the distribution of mutating Ids, verifies the identity of one or more participating parties, and provides tracking information for mapping service providers and consumers to particular, possibly watermarked, content items.

摘要： A plurality of byte ranges including at least one encrypted byte range forms a variant sample for providing a digital watermark in content output by a player device. The plurality of byte ranges is ordered in secured memory, and stored in unsecured memory including one or more encrypted byte ranges for further processing of the ordered plurality of byte ranges. In another aspect, a plurality of byte ranges forms a sample for content output from a player device, and includes at least one double-encrypted byte range. The plurality of byte ranges is stored in secured memory, and the at least one double-encrypted byte range is partially decrypted to generate at least one decrypted singe-encrypted byte range. The plurality of byte ranges is stored in unsecured memory using the at least one decrypted single-encrypted byte range in place of the at least one double-encrypted byte range.

摘要： Systems and methods for determining the authenticity of vehicle operational data provided by telematics or other devices are provided. Vehicle performance and/or operational data may be collected and the authenticity of the data stream may be determined based on the whether the data stream includes a watermark in a predetermined location of the data stream or whether the data stream includes a data key comprising a predetermined false vehicle performance data reading. A second data recording device may also record vehicle performance and/or operational data. Both the first and second data recording devices may provide the respective vehicle performance data to a computing device. The computing device may compare the vehicle performance data from the first and second data recording devices to determine authenticity of the vehicle measurement data.

摘要： A capture device (200) such as a camera and/or sound recorder records an event, which includes a visual and/or audible presentation of a time value that is non-deterministic, yet a function of physical time. The non-deterministic time value (NDT) may be generated as a function of a calendar value created at time intervals as a root hash value of a distributed, hash-tree document authentication infrastructure (500). If the NDT value included in the recording of the event does not match the NDT value corresponding to the calendar value from which it was generated, the recording may be assumed to be altered. Digital time-stamping (600) may be included for the recording of the event to reduce the opportunity for back-dating of the recording. NDT may also be generated simply for display by a clock, for example as an NDT time zone.
