摘要： Moving-picture data in a frame is encoded without depending on another frame of moving-picture data, and moving-picture data in a frame is encoded depending on another frame of moving-picture data. Whether each frame of moving-picture data is a frame which was encoded without depending on another frame of moving-picture data or which was encoded depending on another frame of moving-picture data is determined. The frame of moving-picture data was thus determined as having been encoded without depending on another frame of moving-picture data. The enciphered moving-picture data includes the frame of moving-picture data and the frame of moving-picture data which was determined as being the frame which was encoded depending on another frame of moving-picture data.

摘要： The present invention was made in order to provide a technology capable of safely ciphering compressed and encoded image data irrespective of lines or media and carrying out a correct decoding operation without any shifts in the frames of ciphered moving pictures. Further, so as to prevent giving any means of encoding from comparison of image ciphered data and so as to generate totally different ciphered image data from the same data compressed images, a processing is executed not on an ECB mode but on such modes as CBC, CFB, OFB or the like. Moreover, as an initial vector, information different for frames included in a header, that is, time information from the start of an image or a frame sequential number, is used. In this way, even if compressed images within adjacent frames are accidentally the same, totally different ciphered data can be obtained.

摘要： A file protection system for protecting a file which is stored in a storage unit includes a storage position deciding unit for deciding a positional-information corresponding to an area in which information of the file is stored in the storage unit and an encryption unit for encrypting the information of the file in accordance with a predetermined algorithm using at least a part of the positional-information decided by the storage position deciding unit. Information obtained by the encryption unit is stored in the area identified by the positional-information in the storage unit. A file protection system is operable when information of a file which was encrypted as described above is read out from a storage unit. The file protection system includes a decryption unit for decrypting the encrypted information of the file which is read out from an area in the storage unit using information corresponding the area, an extracting unit for extracting the positional-information from information obtained by the decryption unit, and a determination unit for determining whether or not the positional-information extracted by the extracting unit is equal to corresponding positional-information which is at least a part of the information corresponding to the area from which the encrypted information of the file is read out. When the determination unit determines that two pieces of positional-information are not equal to each other, it is determined that the information obtained by the decryption unit does not include correct information of the file.
