    摘要： Data is protected from unauthorized copying by rescrambling an unauthorized version of the data, but descrambling an authorized version of the data. This is done using a trigger signal. One property of the trigger signal is that it is preserved through signal transformations, such as one or more of compression, decompression, analog to digital conversion, and digital to analog conversion. As a result of this property the trigger signal can be detected in either scrambled or descrambled data. The trigger signal is embedded into the data to form watermarked data. The watermarked data is passed through a descrambler, where the trigger signal, if present, is extracted. A descrambling key and a descrambling algorithm are applied to the watermarked data if the trigger signal is present, but not applied to the watermarked data if the trigger signal is not present.

    摘要翻译： 通过对未经授权的数据进行解密，但是对数据的授权版本进行解扰，可防止数据受到未经授权的复制。 这是使用触发信号完成的。 触发信号的一个特性是通过信号转换来保存，如压缩，解压缩，模数转换和数模转换中的一个或多个。 作为该属性的结果，可以在加扰或解扰数据中检测触发信号。 触发信号嵌入到数据中以形成水印数据。 水印数据通过解扰器，其中提取触发信号（如果存在）。 如果存在触发信号，则对加密的数据应用解密密钥和解扰算法，但是如果触发信号不存在则不应用于水印数据。

    摘要： A method for detecting a watermark signal in digital image data. The detecting method includes the steps of: computing a log-polar Fourier transform of the image data to obtain a log-polar Fourier spectrum; projecting the log-polar Fourier spectrum down to a lower dimensional space to obtain an extracted signal; comparing the extracted signal to a target watermark signal; and declaring the presence or absence of the target watermark signal in the image data based on the comparison. Also provided is a method for inserting a watermark signal in digital image data to obtain a watermarked image. The inserting method includes the steps of: computing a log-polar Fourier transform of the image data to obtain a log-polar Fourier spectrum; projecting the log-polar Fourier spectrum down to a lower dimensional space to obtain an extracted signal; modifying the extracted signal such that it is similar to a target watermark; performing a one-to-many mapping of the modified signal back to log-polar Fourier transform space to obtain a set of watermarked coefficients; and performing an inverse log-polar Fourier transform on the set of watermarked coefficients to obtain a watermarked image.

    摘要： A watermarking procedure that is applicable to images, audio, video and multimedia data to be watermarked divides the data to be watermarked into a set of n×n blocks, such as the 8×8 blocks of MPEG. The same watermark signal can be distributed throughout the set of blocks in a large variety of ways. This allows the insertion algorithm to be changed without affecting the decoders. The decoding procedure first sums together the DCT coefficients of N sets of 8×8 blocks to form a set of N summed 8×8 blocks and then extracts the watermark from the summed block. Since the sum of the DCT blocks is equal to the DCT of the sum of the intensity blocks, efficient decoding can occur in both the spatial and frequency domains. The symmetric nature of the decoding process allows geometric distortions to be handled in the spatial domain and other signal distortions to be handled in the frequency domain. Moreover, insertion of a watermark signal into image data and the subsequent extraction of the watermark from watermarked image data which has been subject to distortion between the times of insertion and extraction involves the insertion of multiple watermarks designed to survive predefined distortions of the image data, such as panscan or letterbox mode transformations. Alternatively, a registration pattern in the image data, after the image data containing the registration pattern is subject to an unknown distortion, is used to compensate for distortion of the watermarked image data.

    摘要翻译： 适用于要加密水印的图像，音频，视频和多媒体数据的水印程序将要加密的数据划分成一组nxn块，例如MPEG的8×8块。 相同的水印信号可以以各种方式分布在整个块集合中。 这允许改变插入算法而不影响解码器。 解码过程首先将N个8×8块的DCT系数合在一起，以形成一组N个相加的8×8块，然后从求和块中提取水印。 由于DCT块的和等于强度块的和的DCT，所以在空间域和频域两者都可以进行有效的解码。 解码过程的对称性质允许在空间域中处理几何失真并且在频域中处理其他信号失真。 此外，水印信号插入到图像数据中，并且随后从插入和提取时间之间遭受失真的水印图像数据中提取水印涉及插入被设计为存活图像数据的预定失真的多个水印， 如平底锅或信箱模式转换。 或者，使用包含登记图案的图像数据之后的图像数据中的注册图案进行未知的失真，以补偿水印图像数据的失真。

    摘要： A computer-implemented process for determining a ranked set of solutions to a bipartite graph matching problem, such is involved in multi-target tracking, maximum flow matching, or data association in matching elements of a first set to elements of a second set to minimize the cost of the association. A feature of the process is a partitioning into subproblems such that the most probable solutions are in the smaller subproblems and the computation begins by solving the smallest subproblem in the search for the best solution.
