ABSTRACT: Now a days passwords are easily identified by others or hackers. And our password is may be same with other ones. Passwords give security but not that much level. Fingerprint Technology gives High and Great Secure. Because Fingerprint is unique. In this paper we cover Introduction to Fingerprints, Optical Scanner, Fingerprint Comparison, Fingerprint verification algorithm, Fingerprint Applications and Fingerprint door locks. “

Introduction to Fingerprints: A fingerprint is an impression of the friction ridges of all or any part of the finger.A friction ridge is a raised portion of the epidermis on the palmar (palm and fingers) or plantar(sole and toes) skin, consisting of one or more connected ridge units of friction ridge skin. These ridges are sometimes knows as “dermal ridges” or “dermal papillae”. Fingerprints may be deposited in natural secretions from the eccrine glands present in friction ridge skin(secretions consisting primarily of water) or they may be made by ink or other contaiminants transferred from the peaks of friction skin ridges to a relatively smooth surface such as a fingerprint card. The term fingerprint normally refers to impressions transferred from the pad on the last joint of fingers and thumbs,though fingerprint cards also typically record portions of lower joint areas of the fingers(which are also used to make identifications) Classifying Fingerprints Before computerization replaced manual filing syatems in large fingerprint operations manual fingerprint classification systems were used to categorize fingerprints based on general ridge formations(such as the presence or absence of circular patterns in various fingers), thus permitting filing and retrieval of paper records in large collections based on friction ridge patterns independent of name, birth date and other biographic data that persons may misrepresent. The mosr popular ten print classification systems include the Roscher system, the Vucetich system,and the Henry system. Of these systems, the Roscher system was

developed in Germany and implemented in both Germany and Japan, the Vucetich system was developed in Argentina and implemented throughout South America,and the Henry system was developed in India and implemented in most English-speaking countries.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
