    摘要： A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.

    摘要： To identify participants in collusion directed to altering a digital fingerprint embedded in multimedia content, an ECC based fingerprinting technique establishes a code symbol for each of a plurality of segments of digital data forming the multimedia content. The code symbols are concatenated to form a fingerprint signal, which is subdivided into a plurality of subsegments for each segment in the digital data. The subsegments are permuted and embedded into the digital data. When a suspicious copy of the multimedia content is discovered, the permuted fingerprint signal is extracted from the content and inversely permuted to form a test fingerprint. The identity of one of the colluders is determined by correlation with characteristics of the codeword originally assigned to the user. The determination of identity may be enhanced by the addition of group data embedded as an additional fingerprint in the digital data. Joint consideration of coding and embedding provide benefits over previous fingerprinting techniques.

    摘要： Visual discomfort from depth jumps in 3D video content is reduced or avoided by detecting the occurrence of a depth jump and by Input video changing the disparity of a group of received image frames including the frames at the depth jump in order to adjust the perceived depth in a smooth transition across the group of image frames from a first disparity value to a second disparity value. Depth jumps may be detected, for instance, when content is switched from one 3D shot to another 3D shot.

    摘要： The present invention discloses a U-type superconductive microstrip resonator and a filter corresponding to the same. The U-type superconductive microstrip resonator is an asymmetric U-type configuration formed by folding the superconductive microstrip, its total length is a half of the wavelength corresponding to the center frequency of the filter constituted by them. A filter can be constituted by a number of said U-type superconductive microstrip resonators as required. In this filter, these U-type microstrip resonators are arranged in parallel in a manner that the longer sides direct a same direction, or in a manner that every two adjacent U-type superconductive microstrip resonators are symmetric about an axis. The filter constituted by said U-type superconductive microstrip resonators can not only achieve the same specification as an open-loop superconductive microstrip filter with a same number off sections, but also achieve a smaller size than the open-loop superconductive microstrip filter.
