Abstract
The security of medical images has attracted much attention recently, especially when these images are hosted by third party cloud service providers and therefore must be sent through the communication networks. A key challenge in the cloud computing paradigm is the design of efficient security schemes that help address the issues of confidentiality, integrity and authentication. Consequently, we propose a fast and robust encryption technique for gray scale medical images for real time applications. Our technique first compresses the medical image in the discrete wavelet transform (DWT) domain before encrypting with an algorithm based on basic pixel permutation and randomness. In the DWT domain, correlation and redundancy are reduced while random pixel permutation with encryption key provides confusion and diffusion. Our simulation results demonstrate the potentials of our technique.
