Abstract

In today’s information age, information sharing and transfer has increased exponentially. The information vulnerable to unauthorised access and interception, while in storage or transmission. The threat of an intruder and Steganalysis accessing secret information for sharing information over an unsecure or covert communication channels are vulnerable to intruder attacks. Although, these techniques are often combined together to achieve higher levels of security but still there is a need of a highly secure system to transfer information over any communication media that minimizes the threat of intrusion. Therefore, to maintain 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 least and most significant-bit (LSB and MSB)-based approach and method of patching by contrasting process.
