An innovative Image Cryptosystem Sequences based on Biological Protein

Image cryptosystem is mandatory to maintain images in a secure format, whether on users IOT devices, the cloud, or fog drives. Many trustworthy image cryptosystems have been used previously to keep image in encrypted safe formats from illegal decryption by adversaries. This article introduces Image-as-Protein Sequence (IaPS), a genuine image cryptosystem depend on disguising image pixels by replacing them with sequences of characters analogous to biological protein sequences and permuting these sequences into different k-mers (frequent and non-frequent), which are then binary encoded into the encrypted file. The proposed cryptosystem scheme was tested with various grayscale and RGB colour images, and its robustness, performance, and security were evaluated.
