Design of the laboratory task for attack on fingerprint authentication

By Jiří Spurný


This thesis deal with personal fingerprint authentication and contains basic types of fingerprint readers included their principles of working. In this thesis are collected published attempts to this type of biometric authentication and in detail described way, how these attempts were realized . Realization of lab measurement is mentioned in practical part of thesis, is designed based on collected and evaluated information. Tendency for realization was to use materials and procedures which are available on market as well as computer technology. So no special equipment is needed for realization. Practical part describes in detail procedures for papillary lines capturing and their electronic processing. Described is also way to break through optical finger print sensor. For confirmation of procedure was made 12 artificial finger casts from Lukopren material. There casts were used to attempt on optical sensor Microsoft Fingerprint Reader with 100% success. Based on realized tests to produce artificial casts was proposed procedure for realization of laboratory measurement. This procedure is described in main part of this thesis. Proposed procedure has been confirmed in 90 minutes time limit, based on requirement to achieve time limit of school training session
