    摘要: A computer-implemented method and apparatus for embedding hidden data in an audio signal. An audio signal is received in a base domain and then transformed into a non-base domain, such as cepstrum domain or LP residue domain. The statistical mean manipulation is employed on selected transform coefficients to embed hidden data. The introduced distortion is controlled by psychoacoustic model to ensure the imperceptibility of the embedded hidden data. Scrambling techniques can be plugged in to further increase the security of the data hiding system. The present new audio data hiding scheme provides transparent audio quality, sufficient embedding capacity, and high survivability over a wide range of common signal processing attacks.

    摘要: Systems and methods to enable real-time and near real-time storyboarding on the World Wide Web in addition to a graphical user interface for video parsing and browsing the of the storyboard. Specifically, storyboarding can be accomplished on the World Wide Web by parsing an input video into representative or key frames. These frames then can be posted to a web document, or the like, for subsequent viewing by a user. This allows a video to be distilled down to the essential frames thus eliminating storage and bandwidth problems as well as eliminating the need for a user to view the entirety of the video. Furthermore, the graphical user interface allows a user to visually interact with an input video signal to determine the key or representative frames, or to retrieve video segments associated with already determined key frames. Furthermore, the interface allows manipulation of these frames including, but not limited to, playing of the entire segment represented by that key or significant frame as well as actual determining of the cuts between significant segments.

    摘要: A data hiding system and method for providing a method of embedding multiple layers of hidden data into multimedia data. First, a media unit of the multimedia data is evaluated to determine an appropriate embedding procedure. Next during a first embedding pass, a ruling layer of primary hidden data is embedded into the media unit. In another embedding pass, a governing layer of secondary hidden data is embedded on top of the ruling layer. The secondary hidden data provides control information for controlling the primary hidden data and the host data. Control information such as error correction data, synchronization data, decoding data, and authentication data is embedded in the governing layer. Embedding schemes such as base domain and spectrum domain embedding are employed.
