DESIGN AND IMPLEMENTATION OF CRIME INVESTIGATION SYSTEM USING BIOMETRICS

ABSTRACT

A fingerprint is the feature pattern on the finger. It is proved through strong evidences that each fingerprint is almost unique in nature. Each individual retains his own fingerprints with the permanent and durable uniqueness. Hence fingerprints are being adapted for identification and forensic investigation. The fingerprint recognition problem can be grouped into two sub-categories: one is termed as fingerprint verification and while the other is termed as fingerprint identification. Additionally, apart from the manual approach of fingerprint recognition by the experts, fingerprint recognition here is usually referred as AFRS (Automatic Fingerprint Recognition System), which is drastically program-based. The proposed system presents the variation of Fast Fourier Transform on finger print recognition by fast fingerprint minutiae extraction and recognition algorithm that improves the clarity between the ridge and valley structures of the supposed to be provided finger print images in accordance with the frequency as well as the orientation of the local ridges and extracting correct minutiae.

Key Words: Binarization, Segmentation, Minutae Extraction, Minutae marking.

CHAPTER ONE

INTRODUCTION

With the introduction of biometrics technology which is an advanced computer techniques now widely adopted as a front line security measure for both identity verification and crime detection, and also others an effective crime deterrent. In an increasingly digital world, reliable personal authentication has become an important human computer interface activity. Fingerprint recognition could be very complex pattern recognition problem. It is difficult to design accurate algorithms that are capable of extracting prolific features and comparing them in a robust way, especially in poor quality fingerprint images and when low-cost acquisition devices with small area are adopted. There is a greatest misconception that the fingerprint recognition is a fully solved problem considering it was one of the first applications of all amongst machine pattern recognition.

1.1 Biometrics

Biometrics is an automated method that recognizes people based on their physical and action characteristics, and is a field that used to authenticate a certain individuals characteristics, recognize a person’s character, or study a person’s measurable characteristics. Among the different biometrics, like face, hand, iris, voice and many others, fingerprints is the most dominant biometric technology in commercial applications due to their distinctiveness, persistence, accuracy, throughput, size and cost of readers.

1.2 Exigency

The time taken for detecting fingerprints is minimum .The Proposed system is useful to investigate the current techniques for fingerprint recognition. The Proposed system is divided into image-preprocessing, feature extraction and feature match. Some optimization at coding level and algorithm level are proposed to improve the performance of fingerprint recognition system with the variation of FFT on stored images. The Proposed system is useful for the low quality fingerprint images. Variation of FFT value on samples produces more accurate results.
