Goal of the course.
This series of lectures is aimed to introduce the fundamentals of biometric technologies for personal recognition.

A biometric system for personal verification is made up of the following modules: sensor, feature extractor, matcher. These modules will be described with respect to two biometrics: fingerprint and facial traits. Multi-modal biometrics, that is, systems which combine information from multiple biometrics, will be also presented. Finally, some open research issues will be introduced. Scientific and technological issues, and a focus on the pros and cons of each biometric system, will be discussed. The course can be considered as a follow up of the “Pattern Recognition” course, since biometrics are a particular application of the concepts explained in that course. Students will visit the “Fingerprint Liveness Detection” Laboratory where they could use some proof-of-concept systems developed by the PRA Lab.
