Abstract

Image encryption plays a major role in information security. It is mainly used to convert the original image into another form. In this work, we propose a bit plane slicing of digital image to provide the more security. The main aim of BPS is used to divide the digital image into 8 bit planes. The bit plane is further rotated in order to provide better encrypted image and to make hacking more difficult. It focuses on two techniques such as bit plane slicing and image rotation for efficient image encryption. The classification of bit plane is used for analyzing the importance played by each bit of an image. It is used to estimate the each pixel of an image. The proposed technique involves rotation of bit planes is employed to make highly secure image encryption. By this method scrambling of an image is based on efficient technique even it is intercepted, the information cannot be understood. It is mainly useful for image compression because it exhibits high coding efficiency. This method which makes the decryption of an image more difficult compared to other techniques.
