DESCRIPTION
The empowerment in wireless communication technologies and sensors have developed the Wireless Body Area Network (WBAN). The rapid growth in physiological sensors, low-power integrated circuits, and wireless communication has enabled a new invention of wireless sensor networks, now used for purposes such as monitoring traffic and health etc. Wireless body area network (BAN) is a promising technology for real-time monitoring of physiological signals to support medical applications. A security system to secure medical information communications using biometric features of the body in WBAN. In order to ensure the trustworthy and reliable gathering of patient’s critical health information, it is essential to provide node authentication servicing a BAN, which prevents an attacker from impersonation and false data/command injection. Biometrics refers to or metrics) related to human characteristics and traits. Biometrics identification (or biometric authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are unique to individuals, they are more reliable in verifying identity than other method like token. Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication.

CONCLUSION
Secure communications in BANs are strongly
required to preserves a person‟s health, privacy and
safety.
Senders electrocardiogram feature is selected as the
biometric key for data authentication mechanism.
The security system implemented with low computational
complexity and high power efficiency instead of
cryptographic key distribution.
