The emergence of fast-growing technology allows users to have a highly effective security systems with electronic identification options. These identification technologies include cash and other smart cards, the user IDsand password system based on and so on. But, unfortunately this is unsafe due to hacker attacks, identity theft, and forgotten passwords.In spite of all the shortcomings and failures of these systems still dominate; However, on the basis of biometric fingerprint authentication or identification of the most efficient and reliable solution for high security.
Introduction to fingerprint authentication
and uses the physiological processes and human behavior in the identification of the user ID. This system of biometric security system for human-centred and is more accurate than the traditional password-based authentication systems, used by many online transactions, confidential financial transactions in the industry, offices, institutions, colleges and security access control systems.
A wide range of fingerprint devices available on the market today that is changing in value and method of splicing fingers mostly involving one or five fingers of a hand. There are different approaches for harmonization of the fingers, as fingerprint minutiae, direct search pattern, moiréfringe and ultrasonic models.
Fingerprints
Fingerprints provide unique identifying pattern for people who are from a template finger ridges that helps capture objects on hand.The Fingerprint scanner is the heart of this automated authentication system, which is responsible for the collection of images based on the models of ridges and valleys of human fingers, and then bring them in line with previously saved template. It consists of the sensors, which are optical, ultrasonic, thermal, capacitor etc, but basically use optical methods and scanning.
These sensors generate image quality top of finger ridges and valleys by overriding inconsistent and incorrect design of the scanned image.These scanners consist of analog-to-digital converter that can handle analog electrical signals to obtain a digital representation of the image. When we press a finger on the fingerprint scanner, it collects the signals, processes the image and retrieves the minutiae of details of the finger. Subsequently, a processing unit or the host receives this information and store it in a database of fingerprints.
Fingerprint Authentication projects Kit
During logon, the storage device compares the previously stored data and displays the appropriate processing of the information.For images, a digital signal processor or PC is very expensive, but on the basis of FPGA hardware favorably because of his speed, low cost, flexibility and portability. This type of authentication uses special algorithms to compare the fingerprint IDs for effective information retrieval. To minimize energy consumption, these systems often get into sleep mode and only become active during fingerprint recognition mode.
Let us look at the practical realization of fingerprint authentication system using microcontroller to handle the data.
Fingerprint authentication and control system devices using microcontroller
This type of authentication or identification system easy and inexpensive and can be easily implemented using the main 8051 microcontroller. In this system of monitoring and control is performed at a high level of security by authenticating users fingerprints.
Block diagram of fingerprint authentication and verification system
The security system can be easily understood using the block diagram of power supply, microcontroller, fingerprints, MAX232, LCD display, switch and signal blocks. The work of these blocks is performed from left to right which thepower supply unit gives all power to the circuit, and the fingerprint module provides input to a microcontroller and then data microcontroller processesthe and thus gives effect to the buzzer, LCD and relay to work loads.
