Introduction Of Biometric Technologies :

Introduction Of Biometric Technologies Biometric Technologies Biometric system is automated recognition of persons based on their biological or/and behavioral characteristics . " Biometric recognition systems process biometric features of a person with the aim of confirming or rejecting that person's identity by using previously gathered reference data. “ Biometrics can better solve the problems of access control, fraud and theft, more and more organizations are considering biometrics a solution to their security problems.

Biometric System Requirements:

Biometric System Requirements Biometric System Fulfill the Following R equirements : Universality: Every person have this feature Uniqueness: No two or more people with the same feature must exist, Constancy: The feature does not change significantly in the course of time, Collectability: The feature must be measurable or collectable Performance :o f the system which allows for quantitative statements with regard to identification accuracy and speed as well as the required robustness in the face of system-related factors, Acceptability : of the system in its practical application, Fake resistance of the system, i.e. robustness against direct methods of tricking the system. Hence, for most applications, practical biometric systems have to perform with and at an acceptable identification accuracy and speed.

Biometrics Fingerprint Recognition:

Fingerprints are the most widely used form of biometric recognition system. Fingerprints are considered to be the best and fastest method for biometric identification Fingerprints are generally accepted as human fingerprint images. Identification can functionally be split up into the following three basic tasks: Biometrics Fingerprint Recognition Fingerprint Scanning, Fingerprint Classification Fingerprint Comparison

Process Of Fingerprint Analysis :

Process Of Fingerprint Analysis Scanning of a fingerprint image. Image quality improvement. Image processing. Feature classification. Feature extraction Verification phase.

Fingerprint Identification Procedure :

Fingerprint Identification Procedure Finger-scan technology is the most commonly deployed biometric technology, used in a broad range of physical access and logical access applications . A Fingerprinting or finger-scanning technology is the oldest of the biometric sciences and utilizes distinctive features of the fingerprint to identify or verify the identity of individuals. All fingerprints have unique characteristics and patterns. A normal fingerprint pattern is made up of lines and spaces. These lines are called ridges while the spaces between the ridges are called valleys. It is through the pattern of these ridges and valleys that a unique fingerprint is matched for verification and authorization.

Steps of Finger-Scan Verification and Identification:

Steps of Finger-Scan Verification and Identification There are many few stages involved in finger-scan verification and identification: Fingerprint image acquisition Image processing Location of distinctive Characteristics Template creation and template matching

Biometric Fingerprint Sensor:

Biometric Fingerprint Sensor Fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted minutiae points) which is stored and used for matching.

Features OF Fingerprint Scanners:

Features OF Fingerprint Scanners Interface: Integrated FBI-compliant scanners often have analogue output and a frame grabber is necessary to digitize the images on internal board to be mounted in the host. In non-AFIS devices, the analogue-to-digital conversion is performed by the scanner itself and the interface to the host is usually through a simple Parallel Port or USB connection. Frames per second: This is the number of images the scanner is able to acquire and send to the host in a second. Automatic finger detection: Some scanners automatically detect the presence of a finger on the acquisition surface, without requiring the host to continually grab and process frames; this allows the acquisition process to be automatically initiated as soon as the user’s finger touches the sensor. Encryption: This is the securing of the communication channel between the scanner and the host. Supported Operating systems: Compatibility with more operating systems is an important requirement.

Types Of Fingerprint Sensing :

Types Of Fingerprint Sensing The most important part of a fingerprint scanner is the sensor. Sensors belong to one of the three families: Optical Sensors Frustrated Total Internal Reflection (FTIR) FTIR with a sheet prism Optical fibers Electro-Optical Solid-State S ensors Thermal Electric field Piezoelectric Ultrasound Sensors

Fingerprint Sensing Method:

Biometric Fingerprint Recognition Advantages & Disadvantages :

Biometric Fingerprint Recognition Advantages & Disadvantages Advantages Subjects have multiple fingers Easy to use, with some training Some systems require little space Large amounts of existing data to allow background and/or watch list checks Has proven effective in many large scale systems over years of use Fingerprints are unique to each finger of each individual and the ridge arrangement remains permanent during one's lifetime. Disadvantages Privacy concerns of criminal implications Public Perceptions Health or societal concerns with touching a sensor used by countless individuals Collection of high quality nail-to-nail images requires training and skill, but current flat reader technology is very robust An individual’s age and occupation may cause some sensors difficulty in capturing a complete and accurate fingerprint image

Conclusion:

Conclusion Biometrics Fingerprint Recognitions system allows for increased security, convenience and accountability while detecting and deterring fraud. Biometric Solution one of the best & strongest security feature to benefit individuals and any institutions . Biometric Technology is very inexpensive and easy to use for many application area.
