Detection of LSB Matching Steganography using the Envelope of Histogram
As well-known, it is hard to detect LSB matching steganography when cover images are scans of photographs, which usually have high-frequency noise. This paper proposes a novel steganalysis method for this issue by making use of the following two facts: One is the local maxima of an image histogram decrease and the local minima increase after LSB matching steganography. As a result, the area bet...
متن کاملAn Improvement on LSB Matching and LSB Matching Revisited Steganography Methods
The aim of the steganography methods is to communicate securely in a completely undetectable manner. LSB Matching and LSB Matching Revisited steganography methods are two general and esiest methods to achieve this aim. Being secured against first order steganalysis methods is the most important feature of these methods. On the other hand, these methods don't consider inter pixel dependency. The...
متن کاملVideo Steganography Using LSB Matching Revisited Algorithm
Video Steganography deals with hiding secret data or information within a video. In this paper, a spatial domain technique for LSB Matching Revisited algorithm (LSBMR) has been proposed, where the secret information is embedded in the cover frames. LSB Matching Revisited(LSBMR) algorithm selects the embedding regions according to the size of secret message and the difference between two consecu...
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 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 ...
