Eigenvalues-based LSB steganalysis
So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...
متن کاملImproved LSB-matching Steganography for Preserving Second-order Statistics
In the paper, for enhancing the security of the traditional LSB matching, two improved LSB-matching methods are proposed. In the steganograhical procedure, the Markov chain distance based on the second-order statistics is chosen as the security metric to control the modification directions of ±1 embedding. The first method is based on stochastic modification, which directly determines the modif...
متن کاملLSB Based Audio Steganography Using Pattern Matching
Security of the digital information is becoming primary concern prior to transmitting the information itself via some media. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification or destruction. In this proposed method, the carrier file and the secret message are taken into audio format and a pattern matchin...
متن کاملReliable Detection of Spatial LSB Steganography Based on Difference Histogram
Detection of hidden messages in images is of great importance for both the network information security and the improvement of security of steganographic algorithms. Based on the statistical observations on the difference histogram of images, a new steganalytic technique capable of a reliable detection of the spatial LSB (least significant bit) steganography is proposed. Translation coefficient...
متن کاملOptimized LSB Matching Steganography Based on Fisher Information
This paper proposes an optimized LSB matching steganography based on Fisher Information. The embedding algorithm is designed to solve the optimization problem, in which Fisher information is the objective function and embedding transferring probabilities are variables to be optimized. Fisher information is the quadratic function of the embedding transferring probabilities, and the coefficients ...
