The Biometric systems are known as the safety modules which diminishes the system's security concerns. In this book we have explored the concept of signature recognition which is one of the behavioral entity of biometric systems. These signatures can be both Online or Offline. Online signatures are captured through a digitizer and processed further. The book further showcases the unimodal and Multi-Algorithmic features. Sectorization of complex Walsh Plane as well as other transforms and Wavelet based transforms has been used and their variants are used for feature vector generation and for...

Biometrics systems perform authentication based on human body features, systems based on only one kind of biometric trait are generally called as unimodal biometric systems. The performance and scalability of a biometric system can be increased by combining more than one biometric trait. Such systems are called as multimodal biometric systems. Being less intrusive and universal fingerprint based systems serve as good option for access control and surveillance. Iris recognition enjoys universality, high degree of uniqueness and moderate user co-operation. This makes Fingerprint & Iris...
