  • Patent number: 5838791
    Abstract: 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.

  • Patent number: 5621794
    Abstract: 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.
