SVD Based Authentication in Remote Health Monitoring System
International Journal of Science and Research (IJSR) · 2016
Remote health monitoring system is a technology to enable monitoring of patients outside the hospitals (e.g. in the home), which may help to increase access to care and reduce the cost of healthcare. Patient's authentication is a necessary security requirement in remote health monitoring system in order to verify whether the sensors are monitoring the right person or not. In this paper, we present a SVD based authentication in remote health monitoring system in order to determine the claimed identity is true or false. The proposed method employs a cascade of two transforms; the 4 level-discrete wavelet transform and the singular value decomposition (SVD). The major steps includes; the watermark embedding procedure, watermark extraction procedure and the verification procedure. The data to be authenticated is encrypted using SHA-1 algorithm used as the watermark bits which is embedding on the singular values of the DWT sub-bands of the sensor data. The claimed patient is verified by comparing the extracted watermark bits with the hash database at the authentication server.
