High-Precision Authentication Scheme Based on Matrix Encoding for AMBTC-Compressed Images
In this paper, a high-precision image authentication scheme for absolute moment block truncation coding (AMBTC)-compressed images is presented. For each block, two sub-bitmaps are conducted using the symmetrical separation, and the six-bit authentication code is symmetrically assigned to two sub-cod...
