Abstract: This paper aims to put forth a novel approach for the secure encryption of images. The technique makes use of superimposition of images along with signal processing techniques to achieve the proposed goal. Two keys are used for this purpose, one is a QR code generated using the mobile number of the sender and the other is a signal generated using a private value. Both the keys are used at different stages of encrypting the image. This encryption scheme follows a pixel wise encryption rather than bitwise or byte wise encryption. This way of encrypting images can be used in chat applications where end-to-end encryption is a necessity. The results obtained are convincing and show that this technique can provide robustness and security for the transfer of images. Further, the results obtained using images of different sizes as well as different keys are compared and plotted.
