Abstract: A data encryption device is connected between an HDD and an HDD controller that controls the HDD. The data encryption device encrypts data that is stored from the HDD controller to the HDD, and decrypts data that is read from the HDD. A CPU of the data encryption device receives a command issued from the HDD controller to the HDD, and determines whether the command is executable at the HDD. When it is determined that the command is executable, the command is issued to the HDD. On the other hand, when it is determined that the command is unexecutable, the CPU prohibits issuance of the command to the HDD. Furthermore, when a command issued to the HDD is a specific command, the CPU bypasses data transferred between the HDD controller and the HDD without encryption or decryption.

Abstract: In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data.

Abstract: This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result.
