What is Biometry

Security plays an important role in present day situation where identity fraud and terrorism pose a great threat. Recognizing human using computers or any artificial systems not only affords some efficient security outcomes but also facilitates human services, especially in the zone of conflict. In the recent decade, the demand for improvement in security for personal data storage has grown rapidly, and among the potential alternatives, it is one that employs innovative biometric identification techniques. Amongst these behavioral biometric techniques, the electrocardiogram (ECG) is being chosen as a physiological modality due to the uniqueness of its characteristics which integrates liveness detection, significantly preventing spoof attacks. The chapter discusses the overview of existing preprocessing, feature extraction, and classification methods for ECG-based biometric authentication. The proposed system is intended to develop applications for real-time authentication.
