Soft Biometrics and Its Application to Security and Business

Biometric technology enables automatic identification or verification of an individual based on the person´s physiological or behavioural characteristics. Soft biometrics is a research topic that has attracted a lot of attention recently. The application of soft biometrics in security technology is very promising because it has strong privacy measures and it improves service quality because service is provided that is appropriate to each subject of the soft biometrics application, i.e., the person picked up on camera. Soft biometrics is defined as characteristics that provide some information about an individual but that lack high distinctiveness and performance to sufficiently differentiate any two individuals. We introduce here a summary of soft biometrics and its applications. We also introduce our work in this field.
