AES Encrypted Wavelet Based ECG Steganography

The patient's confidential data should be safe and secure this is Act by Health Insurance Portability and Accountability Act (HIPAA). At the same time, there is a significantly growth in population. Numbers of patient care canters are used usually around the world in a Point - Of - care (PoC) applications. The Security systems are implemented to provide data integrity, privacy, and accessibility. Therefore, ECG signal of the patients and other physiological data of the patient's like body temperature, glucose level, blood pressure, position, etc., are coll ected by Body Sensor Networks(BSNs) at home. After that it will transmitted over network and then stored at hospital server. In this paper, it used the steganography method which is depending on discrete wavelet transform to accomplish HIPAA act. DWT technique is applied on the ECG signal to hide confidential information of the patient which provides privacy to confidential information. High degree privacy is provided to patient, also Stego ECG remains diagnosable. In this paper the steganography technique is used to provide the three tire securities to patient's data. Our system also ensures safety, scalability, and effectiveness.
