Information Hiding: Steganography and Steganalysis
نویسندگان
چکیده
The goal of steganography is to insert a message into a carrier signal so that it cannot be detected by unintended recipients. Due to their widespread use and availability of bits that can be changed without perceptible damage of the original signal images, video, and audio are widespread carrier media. Steganalysis attempts to discover hidden signals in suspected carriers or at the least detect which media contain hidden signals. Therefore, an important consideration in steganography is how robust to detection is a particular technique. We review the existing steganography and steganalysis techniques and discuss their limitations and some possible research directions.

Detection of perturbed quantization (PQ) steganography based on empirical matrix
Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...
متن کاملA Survey on Image Steganography and Steganalysis
Steganography and steganalysis are important topics in information hiding. Steganography refers to the technology of hiding data into digital media without drawing any suspicion, while steganalysis is the art of detecting the presence of steganography. This paper provides a survey on steganography and steganalysis for digital images, mainly covering the fundamental concepts, the progress of ste...

The information-hiding ratio is a well-known metric for evaluating steganalysis performance. In this paper, we introduce a new metric of image complexity to enhance the evaluation of steganalysis performance. In addition, we also present a scheme of steganalysis of least significant bit (LSB) matching steganography, based on feature mining and pattern recognition techniques. Compared to other w...
متن کاملApplying statistical methods to text steganography
This paper presents a survey of text steganography methods used for hiding secret information inside some covertext. Widely known hiding techniques (such as translation based steganography, text generating and syntactic embedding) and detection are considered. It is shown that statistical analysis has an important role in text steganalysis.
