ECG signals recruitment to implement a new technique for medical image encryption

Electrocardiogram (ECG) signal utilization for medical image encryption (ImgEnc) algorithm was proposed in this manuscript. It will utilize the chaotic logistic map and the generalized Arnold map (Cat Map). To generate initial conditions for Chaotic Maps (ChMp), the ECG signal and wolf algorithm are utilized. Autoblocking diffusion (AutBlk) is done only in the process of encryption. A control parameter generated from the plain-image (Plainimg) generates the main stream, which is effective and safe against selected plaintext (Plaintxt) and known Plaintxt attacks. Experimental findings show that with good efficiency, the proposed algorithm can achieve high security.
