Secured ECG Distribution using Compression and RSA Algorithm for Telemedicine Application

Abstract

The detailed condition of a cardiac patient can be better understood from his ECG. For treatment of the patient over the internet both the security and the bandwidth issues plays a very vital role. A new approach which combines RSA for transmission and SPHIT (Set Partioning in Hierarchical Trees) for image compression which enables uploading of important coefficients of ECG signal. This technique not only provides security but also provides doctor to patient interaction. The simulation results indicate that the proposed method enhances the security for data transmission over the internet with a compression ratio of 2.5. The idea for choosing the SPHIT is it is lossless algorithm and much of importance is to be given to the patient details to provide perfect treatment by all means.
