A system and method is disclosed for allowing content providers to protect against widespread copying of their content, while enabling them to give their customers more freedom in the way they use the content. In accordance with one embodiment, content providers identify their content as protected by watermarking the content. Consumers use compliant devices to access protected content. All of a user's compliant devices, or all of a family's devices, can be organized into an authorized domain. This authorized domain is used by content providers to create a logical boundary in which they can allow users increased freedom to use their content.

A system and method for first changing the encryption key on a self-encrypting disk drive followed by a complete disk wipe. Either process can be separately performed, and they can be performed in any order. In fact, one embodiment of the invention, resets the symmetric key, wipes the disk a predetermined number of times with different predetermined data patterns, and then resets the key a second time. This assures that there is absolutely no way to recover the original key or to read the original plain text data, even if some of it's encrypted values remain on unallocated tracks after wiping. A user can be assured that in milliseconds after starting the wiping process, the entire disk is rendered unreadable and unrecoverable. Verifiable data can be pre-written to a device that is later read back to assure that wiping or firmware-based erase commands have worked.

A method includes: holding a device key provided to an information processing terminal; reading an encrypted content and conversion control information from a recording medium; decoding the read encrypted content using the held device key to obtain a decoded content; converting the decoded content into an export format to obtain an export content; generating playback right information indicating that the information processing terminal can play back the converted export content according to the read conversion control information; and controlling whether the playback right information can be generated according to a first flag.

A security system is disclosed in which a device-specific key value is provided to a security processing device, and then used to derive additional derived keys for use in secured communications. In response to identifying a compromise of the derived keys, the system can be instructed to derive new or replacement derived keys for use in the secured communications. In some embodiments, the security system can be used in a video reception device, to decrypt encrypted video content.

A digital focal plane array includes an all-digital readout integrated circuit in combination with a detector array. The readout circuit includes unit cell electronics, orthogonal transfer structures, and data handling structures. The unit cell electronics include an analog to digital converter. Orthogonal transfer structures enable the orthogonal transfer of data among the unit cells. Data handling structures may be configured to operate the digital focal plane array as a data encryptor/decipherer. Data encrypted and deciphered by the digital focal plane array need not be image data.

Content individualization, including: encrypting a first part of a source data set using a first key creating a first encrypted data set; encrypting a second part of the source data set using a second key creating a second encrypted data set; encrypting the second part of the source data set using a third key creating a third encrypted data set; and combining the first encrypted data set, the second encrypted data set, and the third encrypted data set to form a final encrypted data set. Key words include watermarking and content individualization.

In a system for video data capture and sharing client devices may include one or more video cameras and sensors to capture video data and to generate associated metadata. A cloud-based component may receive metadata from the client devices and requests for sharing video data captured by other client devices. Client devices with requested video data are identified by matching their provided metadata to the sharing request and by their response to an image search query for an object of interest specified in the request.
