The criterion for detecting hidden data in the fractal code of images has been suggested in the article. The approach consisting in estimating steganographic threats of every record in the fractal code has been used. This estimation has been based on the special features of fractal compression. The number of the positively estimated blocks has been used for(More)
BACKGROUND Transposition of the spinal cord made it possible to achieve mobilization of the fixed kyphoscoliosis, significantly increase spinal canal volume and improve spinal canal shape. This helped to eliminate spinal cord compression and achieve complete regression of the existing neurological symptoms. METHODS AND RESULTS We report the clinical case(More)
The method of embedding data into images, which are subject to subsequent JPEG-algorithm processing, has been suggested. The special features of embedding that determine secrecy and stability of confidential data have been considered. On purpose to develop an efficient steganographic method a criterion has been synthesized that has been applied as the goal(More)
