Abstract:

A trust policy is constructed based upon a social relationship between real-world entities. The trust policy may determined based upon a social network and social network maps. The social network map provides a framework to determine social distances. The trust policy provides quick and secure access to desired or trusted nodes while providing security from entities outside the trusted sphere of nodes. The trust policy determined by the social distance may be used for various types of applications including filtering unwanted e-mail, providing secure access to resources, and accessing protected services. File sharing, referral querying, advertisement targeting, announcement targeting, access control, and various applications may be limited using the constructed trust policy.

Abstract:

A system and method for performing video block prediction. Various aspects of the present invention may comprise a first module adapted to receive, during a first time interval, first luma information of previously decoded horizontal luma pixels and calculate a first luma prediction coefficient based on such information. A second module may be adapted to receive, during the first time interval, second luma information of previously decoded vertical luma pixels and calculate a second luma prediction coefficient based on such information. A third module may be adapted to receive, during the first time interval, third luma information of previously decoded horizontal and vertical luma pixels, and calculate a third luma prediction coefficient based on such information. A fourth module may be adapted to receive the first, second and third luma prediction coefficients and pixel coordinate information, and generate a luma pixel prediction value corresponding to the pixel coordinate information.
