Abstract:

With the advent of high speed communication networks, the Internet acts as an efficient and cost effective information sharing channel that makes the globe at large feel like a small digital city. Due to its speed, simplicity and security, digital communication has become an integral part of everyone‘s life. Secure communication of secret data has become a major challenge This paper presents a technique for covert communication of secret data. The secret text data is embedded into the edges of a 24 bit colored image. Experimental results demonstrate that the proposed technique produces a stego image of good visual quality and a reasonably good Peak signal to noise ratio. It was also seen that as the embedding capacity was increased the peak signal to noise ratio reduced. The technique was tested against attacks using a freeware steganalysis tool.
