This includes efforts to influence the determinants of health as well as more direct health-improving activities. Health care providers are institutions or individuals providing health care services. Biometrics is the automated recognition of individuals based on their behavioral and biological characteristics. Biometrics has revolutionized the healthcare industry; devices can take unique information about you from your eye, your hand print, or your thumb print and use it to identify you. This information can be used to ensure that you are who you say you are, and you have permission to be working with the healthcare information you are trying to access. How can we provide an effective form of authentication that is supremely accurate, fast, and convenient, operates on multiple devices, platforms and software, and thereby, give time back to the doctor? The best solution to these kinds of problems is the use of biometric techniques for authentication. Already there are lots of biometric traits have been used for authentication in hospitals. In this paper, the authors are interested to review about the different biometric techniques used in health care systems. Keywords - Biometric, Biometric Security, Healthcare, Fingerprint, Cloud I. INTRODUCTION A health system is therefore more than the pyramid of publicly owned facilities that deliver personal health services. They have also been described in the United States as "the five C's": Cost, Coverage, Consistency, Complexity, and Chronic Illness. Also, continuity of health care is a major goal. Health care providers are institutions or individuals providing health care services. Individuals, including health professionals and allied health professions can be self-employed or working as an employee in a hospital, clinic, or other health care institution, whether government operated, private for-profit, or private not-for-profit (e.g. non-governmental organization). They may also work outside of direct patient care such as in a government health department or other agency, medical laboratory, or health training institution. Examples of
