I. 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...

متن کاملClassification of Image Steganography Techniques in Spatial Domain: A Study
Steganography is a method of secret communication wherein the very existence of communication is hidden. During the last few decades there have been a tremendous development in digital image steganography and a large number of papers have been published by different researchers. This review paper presents a classification of the spatial domain image steganography techniques. These classificatio...
متن کاملA Novel Approach for Image Steganography in Spatial Domain
This paper presents a new approach for hiding information in digital image in spatial domain. In this approach three bits of message is embedded in a pixel using Lucas number system but only one bit plane is allowed for alternation. The experimental results show that the proposed method has the larger capacity of embedding data, high peak signal to noise ratio compared to existing methods and i...
