Image Encrypyion with Edge Detection

Abstract

Steganography is the technique of hiding the communication data by hiding data in another different format of data.Even though many different carrier file formats can be used, digital images are the most commonly used format. For hiding encryption in images, there exist a large variety of steganography techniques; of which some are more complex than others and all of them have their respective strong and weak points. The proposed paper roughly explains and presents the concepts of the combination of cryptography and steganography techniques. This paper proposes 3 techniques for information hiding in RGB color images. (1)Canny Edge Detection for separating am image into edge (2)Least Significant Bit (LSB) technique for hiding encrypted messages in edge, there is no much changes in the embedded image (3) Advance Encryption Standard (AES) for encryption plain text to cipher message.
