ECG Based Biometrics Verification System Using LabVIEW

Abstract

Now days, Biometrics is being used extensively for the purpose of security. Biometrics deals with identifying individuals with their physiological such as fingerprint DNA, ECG etc or behavioral traits i.e. rhythm, gait, voice etc. But some of these biometrics can be copied e.g. voice and fingerprint. They do not provide the guarantee of liveness of the subject e.g. fingerprint of a person who is dead can be taken. So the liveness of the object becomes a necessary requirement for the completion of the biometric system. ECG has the property of liveness. It cannot be collected without the knowledge of the person and it varies from the person to person even in identical twins. Also ECG based biometric system can be easily cascaded with other biometric systems to enhance the reliability and security of the system In the present work an ECG based biometric system has been developed. The developed system uses the LabVIEW (Laboratory Virtual Instrument Engineering Workbench) 7.1 platform. The developed system is user friendly and provides the result in real time. A database of 20 person having 10 samples per person has been created. The experiments conducted on the above database suggest that an accuracy of 97% has been achieved with the developed system.
