Fingerprint recognition belongs to one of the most often used biometric technologies worldwide. Some people whose fingers are affected by a skin disease cannot use this technology which is discriminating for them, since they are not allowed to use their fingerprints for the authentication purposes. This chapter describes research of influence of skin diseases to fingerprint recognition and all supporting and related work of this research. This research requires cooperation of specialists from different professional areas: medical doctors, dactyloscopic experts, IT programmers etc. After some basic introduction to fingerprint recognition several skin diseases which may have an influence on the process of fingerprint recognition are introduced. These were selected from the medical literature in close co-operation with medical doctors. Various diseases which may influence the functionality of fingerprint based systems are introduced in a complete summarization here, divided into three subcategories. This overview from a biometric point of view is followed by a simple introduction into the problematic of dactyloscopic sensors and the description of diseased fingerprint capturing station creation. Last parts of this chapter describe the algorithm for fingerprint image enhancement and process of quality estimation of new diseased fingerprint quality database.
