Overview of Fingerprint Identification

Abstract

This article is an overview of a current research Based on fingerprint recognition system. Here, we have highlighted on the previous studies of fingerprint recognition system and its review in the conceptual &Structur of fingerprint recognition .The basic fingerprint Recognition system consist of four stages: firstly ,the sensor Which is used for enrolment &recognition to capture the biometric data .Secondly ,the pre-processing stage which is used to remove unwanted data and increase the clarity of ridge structure by using enhancement technique. Thirdly, feature extraction stages which take the input from output of the pre-processing stage to extract the fingerprint feature. Fourthly,the matching stage is to compare the acquired feature with the template in the database. Finally the data base which stores the feature for the matching stages .The current trend of fingerprint sensing and identification algorithms are presented in detail in order to show how fingerprint based system works .These include actual example of fingerprint based personal identification system ,large scale fingerprint identification system (AFIS) International activities on standardization and performance evaluation and a “Fingerprint User Interface(FPUI),which is a new type of application of this technology used to enhance human -machine interaction . Also we put in to few suggestions for the errors which occurs in some of the cases due to defects in finger ridges. Also suggesting a multi sensor device.
