Lsb Steganography with Improved Embedding Efficiency and Undetectability
In this paper, we propose a new method of non-adaptive LSB steganography in still images to improve the embedding efficiency from 2 to 8/3 random bits per one embedding change even for the embedding rate of 1 bit per pixel. The method takes 2-bits of the secret message at a time and compares them to the LSBs of the two chosen pixel values for embedding, it always assumes a single mismatch betwe...
متن کاملI. Review of Lsb Image Steganography Techniques in Spatial Domain
(Markus Kahn, 1995) defines Steganography as art and science of communicating in a way which hides the existence of the communication. In contrast to cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganography is to hide messages inside other innocent messages in...

But practical implementation of the definition is not feasible, so pragmatic approach would be to make the algorithm as strong as possible. Steganography is most widely formulated in terms of the prisoner’s problem where Alice and Bob are two inmates who wish to communicate in order to hatch an escape plan. However, all communication between them is examined by the warden, Wendy, who will put t...
