Abstract

An intentional alteration of data stored in a computer through the use of malicious code is a cyber-attack, that exploits networks and computer systems. The data may be compromised and this may have disruptive implications. The proposed system makes use of steganographic method along with visual cryptography for hiding data in images and provide better security. Even though extensive research has been done previously, but most of the research gives no robust security for the image that has been encrypted. The method proposed in this paper is capable of hiding some secret message in least significant bits of the original image, thereby hiding the secret message in way to make its detection difficult. The secret image is then under went to visual cryptography algorithm. Thereby, creating shares of the secret image, which are noise like structures. Further, the method proposes to hide these shares in least significant bits of different images so as to create three levels of security for the message. The main objective of the proposed method is to combine the use of data hiding techniques, steganography and visual cryptography algorithms for designing a secure algorithm so that security, reliability and efficiency of secret message can be improved.
