Efficient Least-significant-bits Steganography for VoIP
For the instantaneity of real-time applications such as voice over Internet protocol (VoIP), the processing delay and efficiency need to be carefully considered. Matrix coding is a widely used coding scheme for steganography to improve the embedding efficiency which means the average hiding bits per covering bit change. In order to take full advantage of it, a classifying least-significant-bits...
متن کاملImage 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 کاملFast Least Square Matching
Least square matching (LSM) is one of the most accurate image matching methods in photogrammetry and remote sensing. The main disadvantage of the LSM is its high computational complexity due to large size of observation equations. To address this problem, in this paper a novel method, called fast least square matching (FLSM) is being presented. The main idea of the proposed FLSM is decreasing t...
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...
