Abstract
In this paper, we propose a new algorithm to encrypt binary images. The proposed scheme is described in several steps. In the first step, we present a new basis to reduce the amount of data required to present the image. In the second step, the image is split into d blocks, which is used in new images of the same size as the original one, and represent them in the new basis to obtain a key-image and encrypted images. The parameters obtained by this transformation are considered as key-image for the encryption and decryption algorithm. The decryption algorithm is performed by the subtraction between each encrypted image and key-image, then summing them in an image to obtain the original one. In the same way, we can apply our proposed algorithm to encrypt a database of binary images. Experimental results demonstrate the efficiency of the proposed approach.
