    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.

    Abstract: A volume coil for a magnetic resonance imaging system is composed of a number of coil units. In the coil, there are overlapped parts between two adjacent ones of the coil units for eliminating coupling between these two adjacent coil units. Two next-adjacent ones of the coil units, which are separated from each other by one coil unit, are each provided with an inductor, and these two inductors are coupled with each other for eliminating coupling between these two next-adjacent coil units. All coil units are collected on one axial end face of the coil. Two coil units in the coil that are neither adjacent coil units nor next-adjacent coil units are connected with each other on the end face by a capacitance circuit or a inductance circuit for eliminating the coupling between these two coil units that are neither adjacent coil units nor next-adjacent coil units. The coupling among the various coil units is relatively thoroughly eliminated, and the signal-to-noise ratio of the signal received by the coil is increased.

    Abstract: Techniques described herein provide security for communications in web mashups. Some implementations secure web mashups by specifying and monitoring a lifecycle of one or more web applications that communicate with each other through implementation of lifecycle declarations. Furthermore, some implementations herein may use access tickets to provide access control between web applications in a web mashup.
