Abstract: This article describes how a new digital spiral phase masked encryption scheme is proposed for health care system based on the Fast Walsh-Hadamard transform (FWHT) to enhance the security of the health-related information systems. The proposed encryption system uses the brain scan image to encrypt brain information from the unauthorized access. Spiral mask used here is a hybrid of Radial Hilbert Mask (RHM) and Toroidal Zone Plate (TZP) Mask which makes the key strong and enhances the security. Proposed schemes not only increase the key space but also increases the number of parameters which makes it difficult for an attacker to find exact key to recover original image. Another advantage of this proposed scheme is FWHT which reduces the quantization error that helps in reconstructing the brain image and information perfectly. The robustness of the proposed cryptosystem has been analysed by simulating on MATLAB 8.1.0(R2012b). The experimental results are provided to highlight the effectiveness, robustness and suitability of the proposed cryptosystem that prove the system can be used in healthcare data encryption.
