A Novel Data Encryption Approach in the Grid-Structured Binary Image

Data hiding from external malicious access is an important and timely issue. Cryptography is the backbone of information or processed data security. The existing cryptography techniques provide good security; however, its computational complexity is also very high. Hence, there is a need of an efficient as well simple cryptography approach. In this context, the paper proposes a novel technique for cryptography in the form of binary textures. The binary textures provide a form of security corresponding to the original message. The binary textures are generated, reshuffled, and arranged in an image form to make it robust from malicious access. The reliability of the proposed approach has been illustrated with some empirical case studies. The overall cryptography process in a digital image makes it a simple, low-cost, and effective methodology for the secure communication.
