摘要： A display processor displays on a display screen an encrypted image accepted by an image data acceptor. An encrypted region acquirer extracts encrypted regions contained on the encrypted image. A target region selector or an authorized target region selector selects decryption target regions from among encrypted regions contained in the encrypted image. A decryption order determiner determines a decryption order of the decryption target regions. The display processor displays on the display screen a prompt for inputting a decryption key (or a password) used for decryption of the encrypted image in each of the decryption target regions in accordance with the decryption order. A decryption key acceptor accepts the decryption key input by a decryption user. An image decryptor performs a decryption process on the encrypted image in the decryption target regions in accordance with the decryption order. A decrypted image of each decryption target region is output.

摘要： A digital watermark embedding apparatus includes an interface circuit which acquires video data and digital watermark information, and a processor which embeds the digital watermark information into the video data. The processor is adapted to, for each symbol contained in the digital watermark information, set a time segment, cause the area of a watermark pattern formed by a plurality of pixels having a prescribed value, and superimposed on each image contained in the video data, to vary in periodic fashion over time in the time segment according to the value of the symbol contained in the digital watermark information, and correct, using the prescribed value, the value of each pixel contained in a region where each image in the video data and the watermark pattern corresponding to that image overlap each other.

摘要： Constraints are added to the size of an encryption area at the time of encryption processing. For example, if the respective number of horizontal and vertical divided blocks is divided by a predetermined positive integer, the size of the encryption area is limited such that the remaining is a certain number of 0 (namely, a multiple of the predetermined positive integer to the respective number of blocks) or 1 or more. Block positions in the encryption area are detected according to the constraints of the number of blocks of an encryption image as the decryption processing corresponding to the encryption processing. Because the number of horizontal and vertical blocks is previously limited at the time of the encryption, the possibility of the number of blocks to be considered in the detection of the block positions is reduced, resulting in improved decryption accuracy.
摘要翻译：限制在加密处理时被加到加密区的大小上。例如，如果相应数量的水平和垂直分割块被预定的正整数除以，则加密区域的大小被限制，使得剩余部分是一定数量的0（即，预定的正整数到相应的块数）或1个或更多个。根据加密图像的块的数量的约束来检测加密区域中的块位置作为与加密处理相对应的解密处理。由于在加密时预先限制了水平和垂直块的数量，所以在检测块位置时要考虑块的数量的可能性减小，从而提高了解密精度。
