摘要： Video media subscribers attempt to circumvent embedded ads in downloads by modifying the media files to render only the content feature. A media program is defined as an integrated set of media files including the requested content feature and the accompanying promotional materials. Media files associated with a particular content feature are stored as an integrated whole, and security tokens computed on selected random portions of the collection of media files that define the media program (content feature and interspersed ads). A hash engine computes a security token on selected blocks of the media files. The security tokens and corresponding metadata are stored in a secure repository. Before rendering the content feature, the hash values are recomputed on the downloaded media program; and compared to the corresponding locations from the stored hash values and metadata.

摘要： A device and method for assisting a user to articulate a limb. The device has an upper section, a lower section, and at least one joint between the upper and lower section. The device comprises an exoskeleton with a first cuff coupled to the lower section of the user's limb, a second cuff coupled to the upper section of the user's limb and a third cuff coupled to a portion of the user's body above the upper section of the limb. At least one cable is attached to the first cuff and at least one cable is attached to the second cuff. A series of drivers located remotely from the exoskeleton are attached to cables and are connected to a processor. The processor transmits signals to the drivers to vary the lengths of the cables to guide articulation of the user's limb.

摘要： A security component may be associated with a network-enabled application. The network-enabled application may request access to restricted content from a relying party (e.g., web site). The security component associated with the network-enabled application may receive authentication policy information from the relying party and send a user's authentication credentials to an assertion provider to authenticate the credentials. The relying party may trust the assertion provider to authenticate user credentials. Upon successful authentication, the assertion provider may return an assertion token to the security component and the security component may sign the assertion token as specified in the authentication policy information. Subsequently, the security token may forward the signed assertion token to the relying party and the relying party may grant access to the restricted content.

摘要： A method, apparatus and computer program product for providing confidentiality, integrity and authenticity for a video file is presented. An encryption header is produced for the video file, the video file including a plurality of packets that carry content, the encryption header containing information necessary to successfully decrypt the video file. The encryption header is added to the video file. An encryption key is generated from a master key identified in the encryption header and, using the encryption key, individual packets of the video file that carry content are encrypted. The video file comprises one of the group consisting of pre-recorded streaming video, live streaming video and randomly accessed video.

摘要： Method and apparatus are described wherein, in one example embodiment, a public key certificate issued by a certificate authority includes at least one characteristic that conforms to at least one rule established for the operation of a public key infrastructure. An attribute certificate is issued to be used to modify the public key certificate in accordance with information contained in the attribute certificate to create a modified public key certificate wherein the at least one characteristic is modified so as to be non-conformant with the at least one rule. According to one example embodiment, the attribute certificates may be distributed by a certificate authority, or embedded in an application that includes an engine that is used to modify the conforming public key certificate.
