Image Security using Image Encryption and Image Stitching

With increase in digital communication, multimedia data such as digital images, videos etc. we require fast and robust security systems. To achieve high security, encryption is one of the way to protect our data from unauthorized users. In this paper, the proposed model aims to provide security to the images using a combination of image encryption and image stitching techniques. The use of chaotic methods in the encryption makes it more difficult for the attackers to decrypt the image. Every image to be transferred is first partitioned and then each part is encrypted and sent to the receiver. That is why a person with a single part or two parts of the image will not be able to use that image. Image stitching algorithm used on the receivers end makes it easy for him to generate the original image. Image encryption along with image stitching provides a double layer of protection to the image. The need for this approach is to achieve security and privacy during the communication.
