Biometric systems – errors and vulnerabilities

Biometry is a fascinating scientific and engineering field which uses knowledge from a number of diverse scientific fields, such as biology, mathematical statistics, forensics, psychology, security etc.


This paper shows biometry independent from technology and emphasizes the flaws and faults of the general biometric system. First we familiarize with general terms from this field. Later is shown biometric system as system for data processing. Then, statistical basis of biometry as well as verification and identification. System faults are shown at the end.
