  1. A Presentation onFingerprint Matching System Presented By: Ajay GopalShrestha SabanamLakhey SajanaShakya Sushma K.C.

  2. Overview of the Project The objective of the system includes: • To develop a system that can identify and authenticate fingerprints. • To match two Fingerprint image which is stored in the database.

  3. Application of Fingerprint Matching System • Forensic CorpseIdentification CriminalIdentification MissingChildren • Commercial Computer Network Logon Electronic Data Security E-commerce Internet Access ATM ,Credit Card Cellular Phone Personal Digital Assistance Digital Learning • Governmental National ID card Driver’sLicense Social Security BoarderControl Passport Control

  4. Block Diagram of the Phases of FMS Physical Fingerprint Classification Decision Figure:Phases of Fingerprint Matching System

  5. Core Algorithms • Image Enhancement (under study phase) Filtering: Gabor Filter • Thinning: Hilditch Algorithm • Matching: Cross-correlation Algorithm

  6. Completed Activities: • Thinning Algorithm: used for single line representation of fingerprint ridges for properly sampled version of fingerprint images. • Matching: Cross-correlation based imagematching (minutia-based matching)

  7. Testing & Trials • Runs successfully for properly enhanced images/oriented images. • Fails for low resolution images where orientation is changed.

  8. Problems • Dryness of skin ,worn-out ridges, skin disease, sweat, dirt and humidity in air all contribute to the non-ideal contact situations. • The variation of the pressure over the region of contact of the finger and the scanner. • Image acquisition and binarization of the acquired image has been difficult.

  9. To do activities

  10. Motivation behind it • Finger-print recognition is used in various systems for Verification, Identification etc. • Recognizing manually can be very time consuming and costly. • There are systems already in use which use similar technology and a lot of research is going on to improve the technique.
