Abstract: The patients 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 centers 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 collected 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. First security is providing by share key, second security is providing by scrambling matrix, third security is providing by vector level. Share key which is used for security is coded by ASCII value. XOR ciphering technique is used for share key. Share key value and scrambling matrix value should be same at transmitting side and receiving side of the data. Vector level is nothing but steganography level. Our system also ensures safety, scalability, and effectiveness
