Image complexity and feature mining for steganalysis of least significant bit matching steganography
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 کاملAn Enhanced Least Significant Bit Steganography Technique
Message transmission through internet as medium, is becoming increasingly popular. Hence issues like information security are becoming more relevant than earlier. This necessitates for a secure communication method to transmit messages via internet. Steganography is the science of communicating secret data in several multimedia carriers like audio, text, video or image. A modified technique to ...
متن کاملFeature mining and pattern classification for steganalysis of LSB matching steganography in grayscale images
In this paper, we present a scheme based on feature mining and pattern classification to detect LSB matching steganography in grayscale images, which is a very challenging problem in steganalysis. Five types of features are proposed. In comparison with other well-known feature sets, the set of proposed features performs the best. We compare different learning classifiers and deal with the issue...
متن کاملEnhancing the Least Significant Bit (LSB) Algorithm for Steganography
Various Steganography algorithms have been proposed and implemented for hiding the existence of data in a cover object starting from the algorithms that work in transform domain to the ones that work in spatial domain, such as Least Significant Bit (LSB), which uses the three colours (RED, GREEN and BLUE) present in an image. Three colours are present in the pixel of an image, therefore, this p...
متن کاملImage steganography and steganalysis
Image steganography is used to embed covert messages in the form of files, text, or other images in digital images. The intent is to transmit hidden information. Steganalysis is the process used to detect hidden messages in images. Although steganography is not a new discipline, it has become increasingly important in today’s digital world where information is often and easily exchanged through...
