Steganography of ECG Signals for Hiding of Patient Confidential Data

Abstract

Personal Health Record (PHR) refers to the internet-based portals or computer-based applications that records patient confidential information in electronic version. The patient's privacy and security is important in the protection of healthcare privacy. The patients confidential information sent through the public network should be protected and secure. Patient can control who will use his/her confidential health information, such as name, address, telephone number, and Medicare number and who can access data. Monitoring patients at their home can reduce the increasing traffic at hospitals and medical centres. In this paper issues involving digital steganography and its applications in ECG have been discussed. We reviewed the literature on PHRs including design, functionality, implementation, applications, outcomes, and benefits. We implemented the Wavelet based ECG watermarking for Protecting Patient Confidential Information in Point-of-Care Systems.
