WHAT IS BIOMETRIC SECURITY?
It is a security mechanism used to
authenticate.
Based on Human Characteristic.
Often used Critical Environment.
BIOMETRIC DEVICES
WHAT IS WBAN?
Smart biomedical sensor platform
Analyze the measured signals and
transmit them to user interface
wirelessly.
Consist of a set of a mobile and small size
intercommunicating sensors.
Limited Resources
Working of WBAN
SECURITY ISSUES IN WBAN
Security Problems in WBAN
Less Extent on Evolving Network Protocol
Cryptography Techniques are used in WBAN
Problems in Cryptographic Technique
Complex and Difficult to use

APPLICATIONS OF BIOMETRICS
Biometric Time and Attendance
Biometric Safe and Locks
Securing Access To PC‟s
High End Security
Identifying Criminals

Fraud,
Forgery
DISADVANTAGES
limited by many situations
Affordability
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.
