摘要： A recording/reproduction device 10 receives content broadcast from a content provision device 11. The recording/reproduction device 10 encrypts the received content using a device key, to generate first encrypted content. The recording/reproduction device 10 decrypts the first encrypted content to obtain the content, performs an image conversion on the obtained content to generate converted content, and encrypts the converted content using a medium key to generate second encrypted content. The recording/reproduction device 10 writes the second encrypted content, the medium key, and the device key to a portable medium 14. When the portable medium 14 is inserted in a mobile information terminal 15, the mobile information terminal 15 decrypts the second encrypted content using the medium key to obtain the converted content, and reproduces the converted content.

摘要： To provide a terminal device with which, even if content that has undergone conversion is moved to another device, the content before the conversion can be used when moving the content from the device which is a move destination of the content back to a move source of the content. The terminal device stores the content in advance, applies an irreversible conversion which causes a decrease in quality to the content to generate converted content, and writes the converted content to a storage medium. The terminal device encrypts a block in the content using an encryption key to generate an encrypted block, replaces the block in the content with the encrypted block, and writes the encryption key to the storage medium.

摘要： When creating a marker, an encryption apparatus extracts each pixel value in a region and allows a storing unit to save, as restoration information, the high-order bits of each extracted pixel value. Then, the encryption apparatus creates a marker by changing the high-order bits of the pixel value in a region in which the marker is created and embeds encrypted information in an encrypted region specified by the marker. When decoding the encrypted information, a decoding apparatus detects the marker from a digital image, decodes the encrypted information in the encrypted region specified by the marker, and overwrites bits contained in the restoration information with the high-order bits of the pixel value of the marker.
摘要翻译：当创建标记时，加密装置提取区域中的每个像素值，并且允许存储单元将恢复信息保存在每个提取的像素值的高位中。然后，加密装置通过改变创建标记的区域中的像素值的高位来创建标记，并将加密信息嵌入由标记指定的加密区域中。当对加密信息进行解码时，解码装置从数字图像中检测标记，对由标记指定的加密区域中的加密信息进行解码，并且以包含在恢复信息中的比特的高位标记。

摘要： An image processing apparatus includes: an interface unit for acquiring a readout image produced by capturing an image formed on a medium; a storage unit for storing a plurality of templates generated by superimposing different amounts of blurring on a prescribed pattern contained in the image, and for storing the amounts of blurring superimposed on the respective templates; and a processing unit adapted to detect a pattern region where the prescribed pattern is located on the readout image, calculate the degree of matching between the pattern region and each of the plurality of templates and, based on the degree of matching, identify a template that most closely matches the prescribed pattern located on the readout image, and estimate that the amount of blurring corresponding to the most closely matching template represents the amount of blurring superimposed on the readout image.
