Fingerprint scanner working can be easily understood by thinking of traditional procedure of identification, in which thumb and/or finger impressions were taken using inkpad in order to identify a person. Fingerprint scanner working process includes a hardware device with a scanner on which a person can swap a finger or thumb. The swapped finger or thumb impression is then matched with the copy of impression that is stored in the database.
Fingerprint scanner working process then identifies a user on the basis of matched or mismatched thumb or finger impressions. If the fingerprints are matched during fingerprint scanner working process, the user is allowed to access the information, or enter the classified area. On the other hand, if fingerprint impressions are not matched during the fingerprint scanner working process, the user’s access to the classified area or sensitive information is straightaway denied.
