Abstract: An embodiment of an apparatus to authenticate a sequence of video frames includes a process to choose intra-frames of the sequence and sample DC components thereof to produce a set of test fingerprints. To reduce a dimensionality of the test fingerprints, the DC components of the chosen intra-frames are multiplied by a projection matrix formed of eigenvectors associated with the larger eigenvalues of a covariance matrix for a library of frames. The projected test fingerprints are compared against a reference set of fingerprints for authentication. Time-stamp spacings of the chosen intra-frames are determined, and these spacings are employed to select candidate frames for authentication in the reference set of fingerprints.

Abstract: The ability to remove a watermark from encoded content (e.g., an image) opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e.g., encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

Abstract: Described are methods and devices for automatically coupling two or more mobile communication devices (502, 541) to share content such as calls, music, documents, video and games where two or more devices automatically determine the feasibility of sharing the content and negotiate to find an efficient manner in which to do so. In this way, the pairing between devices may be transparent to the users. Moreover, a better choice in a transport may be selected without user input. Each device may include a near field communication (NFC) device that when in range of the other device may automatically initiate pairing between the devices so that the devices may share content. The users of NFC enabled devices may have little or minimal interactions except that one or more users may bring the devices within range so that the NFCs may initiate the pairing between the devices.
