Development of the Identification System by Fingerprints

Abstract

Dactyloscopy (fingerprint recognition) is the most developed to the date biometric method of personal identification. The catalyst for the development of the method was its widespread use in criminology of the XX century. As each person has a unique papillary pattern of fingerprints, so identification is possible. Typically, algorithms use characteristic points on fingerprints: the end of the pattern line, branching lines, single points. In addition, information about the morphological structure of the fingerprint is attracted: the relative position of the closed lines of the papillary pat- tern, “arched” and spiral lines. Peculiarities of papillary patterns are converted to some unique codes, which preserves the information content of the fingerprint image. And it is “fingerprint codes” that are stored in the database used for searching and comparing. Currently, fingerprint recognition systems occupy more than half of the biometric market. A lot of companies are en- gaged in the production of access control systems based on the method of fingerprinting identifi- cation. Due to the fact that this direction is one of the oldest, it has become the most widespread and is currently the most developed. Fingerprint scanners have come a really long way to improve. Modern systems are equipped with various sensors (temperature, pressing force, etc.), which in- crease the degree of protection against counterfeiting. Every day the systems become more con- venient and compact.
