- Abstract
With image integrity in mind, the sensitivity-of-tamper property of a new image authentication scheme is always one of main concerns. However, to claim integrity guarantee of image authentication techniques is meaningful only when the false negative probability is taken into consideration. In this paper, the security of an image authentication scheme based on Block-Truncation-Coding (BTC) compression proposed by Li et al. is analyzed. The false alarm of their scheme is shown unneglectable in this paper. Precisely, it is potentially problematic since their scheme only protects the quantization values of BTC codes, but ignores the bitmap part. The main weak design will be shown by means of conducting some counter experiments. Thanks to Li et al.’s well design to protect the two values of quantization levels of the compressed image, the improvement to remove the potential security concern is simple. The experimental results and the further analysis demonstrate that the simple and secure improvement does work.
