    Abstract: Mobile device assisted secure computer network communications embodiments are presented that employ a mobile device (e.g., a mobile phone, personal digital assistant (PDA), and the like) to assist in user authentication. In general, this is accomplished by having a user enter a password into a client computer which is in contact with a server associated with a secure Web site. This password is integrated with a secret value, which is generated in real time by the mobile device. The secret value is bound to both the mobile device's hardware and the secure Web site being accessed, such that it is unique to both. In this way, a different secret value is generated for each secure Web site accessed, and another user cannot impersonate the user and log into a secure Web site unless he or she knows the password and possesses the user's mobile device simultaneously.

    Abstract: Methods of embedding and detecting watermarks in video use temporal analysis to compute temporal components of video from which the watermarks are embedded and detected. Temporal analysis, such as a temporal wavelet, is used to compute representations of static and dynamic portions of the video. For embedding, watermarks are computed from and/or adapted to the temporal components. For detecting, temporal properties are exploited to detect watermarks in the static and/or dynamic components. Temporal analysis also enables plural watermarks to be embedded at different levels of temporal resolution.

    Abstract: A method for embedding data into a media signal receives a media signal, divides the media signal into blocks of samples, and calculates a function of the samples in the blocks, including transformations of samples in the blocks to corresponding block values. A processor uses the block value to determine a factor for samples in the blocks to be multiplied by the samples so that when a data embedding function is evaluated for the block, an output of the data embedding function corresponds to a data value representing desired digital data embedded in the block. A compatible decoder extracts this embedded data from the media signal. The decoder divides the media signal into blocks of samples and calculates a function of the samples in the blocks, including transformations of samples in the blocks to corresponding block values. A processor processes the block value to evaluate a data embedding function to determine digital data embedded in the block.

    Abstract: Systems and methods provide a content encryption schema for integrating digital rights management (DRM) in a multicast/broadcast encryption system. In one implementation, an exemplary integrated key schema provides content encryption keys that can be employed by a multicast or broadcast process, while providing DRM protection of recorded multicast content via a single DRM decryption secret. The integrated key schema provides high security and allows encrypted multicast content to be saved directly to local files. A license server can efficiently manage and generate DRM keys to be delivered to clients because only a single key needs to be delivered per license to a client. The integrated key schema can be applied together with conventional broadcast or multicast encryption techniques.
