Patent number: 5838791Abstract: 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.Type: GrantFiled: August 9, 1995Date of Patent: November 17, 1998Assignee: Fujitsu LimitedInventors: Naoya Torii, Noboru Iwayama, Masahiko Takenaka, Takayuki Hasebe, Masahiro Matsuda
