%X This paper presents a universality method for measure of security in steganography.According to the definition of K-L divergence and the properties of security in steganography,some limitations in Cachin's definition of security are shown in the beginning.Besides the divergence of probability distributions between stego and cover,the sample size and the cardinality of the state set of random variable have great effect on security in steganography.Based on K-L divergence and hypothesis testing,an amended mea...
