摘要：A novel benchmark for efficiency evaluation of steganalysis is presented in this paper. The efficiency metric reflects the detection accuracy of steganalysis, which is an important index to evaluate the performance of steganalysis schemes. The main idea is to evaluate efficiency in terms of KL divergence between the distributions of cover and stego images. The three stages in the processing of steganalysis are analyzed, on the basis of which metric E is measured by relative performance. The common LSB based steganalysis schemes are evaluated by metric E. Experimental results show that the index E given here can measure the efficiency of steganalysis schemes effectively. ? 2009 IEEE.
