To develop a three-layer encryption framework that ensures secure transmission and storage of medical images, while allowing lossless reconstruction for accurate diagnosis.
Proposed a three layer medical image encryption algorithm based on semantic bit-planes.
Each layer was encrypted using a different cryptographic key derived from a single SHA-256 master key.
Evaluated the encryption performance across different imaging modalities using metrics like entropy, NPCR, and UACI.
Achieved an average entropy of 7.9998, indicating high randomness.
Recorded an NPCR of 99.61%, showing significant pixel change when a single pixel in the original image was altered.
Demonstrated infinite PSNR confirming perfect lossless reconstruction.
