摘要：In recent years, Steganography and Steganalysis are two important areas of research that involve a number of applications. These two areas of research are important especially when reliable and secure information exchange is required. Steganography involves embedding of message into a cover media and hides its existence. On the other hand Steganalysis is the technology that attempts to defeat Steganography by detecting the hidden information and extracting. So for the maintenance of secrecy either we need to make more robust steganography techniques against steganalysis or discover new and better techniques. In this paper, we propose a novel and more robust image steganography technique that embeds message into a cover media and hides its existence and can verify the reliability of the information being transmitted to the receiver. In order to hide secret data in cover-image it used the Image and Text files representation in Array, that takes the alteration component based approach and method of Palette Based Images. The bits of encrypted message will be hidden inside the stretched palette of image. Also the results demonstrate the relationship between different images and its capacity.
