A Novel and Secure Hybrid iWD-MASK Algorithm for Enhanced Image Security

With the rapid growth of technology dependency over use of digital data is increasing day by day. In dDesigning digital communication systems to keepmaintain the security of data intact at all levels is important, and is considered as a vital issue in the field of digital computing. Use of digital images for the vast variety of applications in military, medical, and other sectors areis gaining a lot ofgreat popularity. Owing to this, Therefore, there is a rising demand ofto enhance the security of digital imaginge security. In this paper, we have focused on the protection of privacy, protection and proposed one of the swarm intelligence based algorithm known as “intelligent water drop-matrix array symmetric key” (iWD-MASK) for encryption and decryption of digital images. Here, the MASK approach has been implemented to generate the key of sizewhich is 128 bits in size. Also, use of an intelligent water drop algorithm implements the concept of soil particles and velocity to increase the confusion for any attacker(s) if they try to execute any attack on the image. We have also provided the detailed comparison of the proposed iWD-MASK with other hybrid approaches like MAES + Chaos and MASK + Chaos. The proposed algorithm uses three metrics, viz., precision, recall, and F-measure to evaluate the overall performance and the obtained results shows a significant improvement infor encryption and decryption of digital images over other approaches.
