IoT Framework for Secure Medical Image Transmission

Abstract

Medical image encryption plays a pivotal role in telemedicine and healthcare applications. Authentication of medical images require a must attention owing to the amount of medical data being communicated and number of digital records being created and maintained. In this work, a server - client model of authenticated medical image communication is proposed. Initially, the AES encrypted medical image is further secured by embedding a One Time Password (OTP) generated through Tent map. This OTP embedded image is shared to the intended user via intranet. Upon receiving the OTP through GSM, the authorized user verifies the similarity of received OTP in mobile and extracted one from the encrypted medical image. After integrity checking, the decryption is performed to retrieve the original medical record. The proposed work of medical image encryption has been developed using python 2.7 and validated by performing entropy, correlation, differential, error metric and NIST test analyses.
