Abstract: Image security is a major concern as the digital communication and digital data is growing rapidly. Image data is generated in loads every day. We need faster and robust mechanisms to secure the image data. Various fields such as military scopes, security firms, social network etc. need systems that can protect the images while communicating and data transfers. In this paper the proposed idea involves use of image encryption using chaotic approach with a combination of image stitching mechanism. This unique combination provides double layered protection to the images. In order to transfer an image, the image is first partitioned, encrypted and then transferred making it difficult for attackers to access the whole image. On the other end, the encrypted image is decrypted using a symmetric key generated using chaotic approach that uses logistic map function and linear feedback shift register which is followed by image stitching procedure..
