ABSTRACT Nowadays, the safety of digital images draws much concentration due to the fast progress of an information technology and the computer networks. Therefore, for protecting such images during transmission and storage, I have proposed a new secret key image encryption approach by using block-based image transformation. Proposed encryption approach is based on partitioning of a bit pattern where the target image is simply encrypted by dividing it into 8 ?8 blocks without any overlapping and converting each block of an image into other form. At the receiver side, target image is recovered from the scrambled image by applying the exactly inverse method. Different experimentations are carried out on different images like Lena.jpg, Babbon.png, Jetplane.tif, etc. to verify the effectiveness of the proposed approach. The experimental outputs of the proposed approach shows that the correlation between image pixels is noticeably reduced by using the proposed algorithm. The experimental outputs also shows the good entropy value of an obtained encrypted image and thus provides good level of image security. Keywords: Image encryption, Image Transformation, Image correlation, Image entropy.
