Survey on Wavelet based ECG Stegnography for Protecting Patients Confidential Information

In this modern era, the use of e-health application is widely increased. Majority of the aging people are suffering from cardiac dis-eases, so it is very crucial important to save the patient’s life by diagnosing cardiac diseases on time, by make use of these e-health applications. The best example of this is of Remote Cardiac Patient Monitoring application. Thus Point of Care systems make use of this application. With the growth of human rights, people are more and more concerned about the privacy of their information and other important data. The objective of this paper is to makes use of electrocardiography (ECG) data as host signal in order to protect individual information. An ECG signal can not only be used to analyze dis-ease, but also to provide crucial biometric in-formation for identification and authentication. Thus we are integrating patients physiological readings like blood pressure, temperature, glucose level, etc into patients ECG, and this host signal will watermarked and transmitting to re-mote patient monitoring system via public net-work. This paper introduces a wavelet-based steganography technique which combines encryption and scrambling technique to protect patient confidential data. After several experiments and evaluation this study proves that host signal will not affect any distortion and is less than 1%.
