Secure Steganography, Compression and Transmission of ECG signal for Protecting Patient Confidential Information in Point-of-Care Systems

ABSTRACT Considering the growth in population and many of the people are in troubled from cardiovascular diseases, The ECG patient remotely observing systems are probable to be broadly used as point-of-care in hospitals and also all over world. Hence, very large number of ECG data obtained by patient body sensor networks by remote patients from their places will send with physiological information that is temperature, glucose level, blood pressure, so on,. It is more important that patient’s confidential data are secured when it is placed on the server of a hospital and also used by remote watching system when required. Thus, in this paper recommended to use Wavelet based steganography method which make combination of encryption and scramble method to secure patients confidentiality. These proposed technique permits ECG signals to hide patient’s confidentiality and also other physiological data’s hence also provide integration of ECG signal and patients private data. To estimate the good effects of the given method on the ECG signals, there are two distortion measurements metrics are used- the percentage of residual difference and wavelet weighted PRD. It is discovered that this process provides very high-security system for patients information with less distortion and ECG signal being diagnosable after of watermarking and along with after watermarks are eliminated from the watermarked data. It is expected that the water-marked ECG signal are used for diagnose and the hidden information all are removed.
