Biometric Access Control System

Abstract

Safety has been playing a key part in many of our places like offices, institutions, libraries, laboratories etc. In order to save our data privately so that no other illegal person could have an admission on them. Nowadays, at every point of time, we need security systems for security of appreciated data and even money. In this report we will introduce a finger print lock system which we can use in banks, many.

There are many like RFID security system, color coding security, lock and key security system. We will provide a best security system by taking help of Biometric and Embedded system. We know that the fingerprint the can’t match of different people. So it will be the best security system. We will save the fingerprint of some people and then we create the project. The purpose of the project is that when the finger print match the door will be open and other than the buzzer will be horn.

At the present time, security device has evolve addicted to the protection apparatus that implanted and use a micro-controller in common language we say that electronic security devices. with the microcontroller which is generally named electronic security device. There is numerous verification method for the electronic security devices such as some are biometric and some are password based, some are simple security devices we can use all these devices as our protection. In all these devices some are cheapest and some are expensive. This is an Embedded base security device which by means of Finger print sensor as a security system.

Chapter 1

1. Introduction

Security of treasures is as vital as their achievement. Treasures extending from human lives to luxurious resources and penetrating data essential to be tightly protected. In these day when armed stealing has gotten more cultured predominantly in developing countries, there is the essential of most secured security systems means, and one of the greatest protected technologies that can be employed is biometrics, finger print door lock to be accurate. Biometrics is the knowledge and technology of determining and investigating biological data, biometrics methods and investigates human body features such as fingerprint, DNA, fingerprint, eye iris, facial pattern, voice pattern and hand measure men.

The Biometric Access Control System of security using the finger print equipment was constructed around a microcontroller, Arduino Uno, which detect in finger prints from finger print sensor and access, to a sheltered room, only to pre-registered finger print(s). The fingers print Sensor functions as the focal input for this security system. Finger prints detect and compared to which is already programmed into the celebration of the Finger Print module. When a match is completed, the microcontroller outputs make the servo to opened the Door and the door will remain open few minutes become closes after the few minutes’ A 16×2 LCD is used in this project to show the status of this implanted security system. By default, it displays a welcome message entreating that the user should enter a finger print. And when a match is prepared it displays a conforming message. The steps that make up the project of the progress of a finger print control using standard door finger print sensor are explicated completely in the fourth chapter of this project report.

The rind on our tributes and fingers shows a flow like designs of edges and valleys. The papillary elevations in the finger, called friction ridges, which relief the hand to hold items and increase roughness and increase the tangible detecting of the surface construction. These ridge patterns are now methodically proved as single for each person. The scratches and injuries in a person’s finger may alter these designs provisionally but they resurface after the wound rectifies. Fingerprints are now used extensively for documentation and authentication purpose. They are used for appearance purpose in administrations to avoid deputation for criminal ID like extremist, murderer and violators and also in passports (a material of national high position) of person.

This system emphasis on the usage of fingerprints for door system. The fingerprint appreciation software allows fingerprints of legal users of the automobile to be registered in a record. Before slightly operator can usage the automobile, his fingerprint duplicate is matched beside the fingerprints in the record while operators with no match in the database are disallowed from using the vehicle. A microcontroller stores the data equal of fingerprint of user. Assessment between this registered fingerprint and fingerprint of person which is about to use the vehicle is done by the micro- controller. If both the fingerprints are equal control motherboard of the controller sends fitting signals to the servo motor which open the door when finger print is match. If the fingerprints are not equal controller direct signals to alarm motherboard to inform about an illegal usage.

Human ID field is very important and has experienced rapid variations with time. A significant and very dependable human ID method is fingerprint ID. Fingerprint of each person is matchless. So this relief in recognizing a person or in educating safety of a scheme. Finger print of an individual is detecting by a singular type of device. Finger print sensor would be interfaced with an Arduino. Using keypad, we can increase user and remove the current user, also recognize the operator by choosing conforming option through keypad. In our system we use a fingerprint module to detect one’s individuality to automatically function the door of an office, house, or a car.

For this, we use a controller to allow the door closing or opening or if the identical between skimmed data and the already current data is correct. Judgement is done confidential the finger print module himself and its result t is given to controller. Outcome is displayed in a LCD show whether the operator is official or not. Liquid Crystal Display also reliefs to make troubleshooting cooler. Alarming option is providing to inform about an illegal usage. Controller used is Arduino Uno R3.

7. Presentation of the findings

Our objective was to unlock the Door by using Finger print sensor. After doing a lot struggles and works we reach our objective. By using both main parts of our project e.g. Hardware and Software we got our result.

Hardware results

The hardware we are using are bread board, male and female wire, Finger print sensor, Lock, Arduino board i.e. Uno R3, and also for driving lock we use servo motor. All these parts are doing work according to our requirement. Our mission was to unlock the door by using finger print sensor the hardware parts are doing work properly. Our finger print is saved in finger print sensor. So when we add the finger which is save in finger print sensor, the servo motor do work on lock. the move them toward back for some the will be open and the man can easily go toward room. For using finger, we also use the Led, which are on lock. By the led we can learn what is our next step.

Software results

The software we are using are Arduino 1.0.6 and Proteus. These are the main part of our software. Arduino 1.0.6 have built in library and Proteus is use for simulation with Arduino and components which we are using in this project. In Arduino 1.0.6 we paste code and verify then create hex file to simulate with Arduino. This work is software to software. Our result was better in software every things was doing work according to our requirement

8. Recommendations

Device Sensitivity:

it is very small problem regarding sensitivity of a fingerprint module, in sensitivity has caused a problem regarding delay in detection fingerprints of a person thus there should be a new device formed, whose sensitivity is high. So once the sensitivity of a device is solved, the fingerprint module will work efficiently.

Physical condition:

It can be make mistake with the finger skin depending about the physical condition whether it is dry or wet. It may be not appropriate with the children finger as their size of finger changes quickly. So by updating the software coding as well as the device, we can eliminate this physical skin changing or in case of finger injury.

Criminal identification:

For some people, it’s very disturbing, because it was long ago related to criminal identification and some people still think that this device is still for the criminal identifications. So we should aware all the people about its useful and positive aspect.

Memory:

Image captured at 500 dpi (dot per inch). resolutions are about 8 bit per pixel. 500 dpi fingerprint image at almost 8 bit per pixel which needs large space. So we should update the software so that maximum number of fingerprint can b enroll in the device.

Chapter 5 1. Conclusion

When the code matches with the thumb/finger, it will allow the person to pass, if the code does not match, then it will not allow the person to pass, as according to the coding, it will not allow to open the door. In addition, this development also aims to decrease the option of the code being stolen by the observer. An official person has their fingerprint physical characters and aspects and turned into an arithmetical logarithm which is to be then entered in to the database, as this all process is being done in the coding of fingerprint module.

The 1^st purpose is totally pleased as this lock allow the passing of only authorized person whose verification is being matched with the coding which was done on Arduino and simultaneously not allowing to pass the parson whose thumb expressions are not being matched with the Arduino coding.

The 2^nd purpose is that the when a fake people try to unlock could not open the door and the buzzer will horn.

There are some of the most important goals and conclusions of biometric verifications i.e. describing in points.

These are the aspects which we have concluded. The following conclusions are as under:

Biometric finger print lock has gained a remarkable advantage as compared to usual key door locks, keyless password type locks. Thus, finger print door exceeds best security protection as it is easiest and time saving process.

Fingerprint door lock technology is the latest and the best proven technology.

Fingerprint reader verification is the most appropriate and the mature tested type of biometric verifications. Fingerprint verification is considered as the most realistic for its cost effectiveness and consistency.

Recent studies on Biometrics verification have shown us that as compare to the hand method i.e. password method or keys method, fingerprint is more accurate and efficient as well as cost effective.

Duplication of fingerprint technology is impossible. Biometric verifications provide a guarantee to the user identification with something that cannot be fake, stolen, replaceable, lost or replicated.

Fingerprint biometric locks are of great outlay for any home. As it increases its level of security while it adds salient feature that make it easier for us to get in home. These door verification technology is easily to make and maintain as we have not to worry about any extra burden of work. Fingerprint ID improves the security of an automobile and makes it potential only for some particular people to usage the flatcar. Thus by applying this relatively inexpensive and simply obtainable system on a flatcar, one can safeguard much better security and snootiness than that obtainable by a conservative lock plus key. It can be presumed that the usage of biometric safety systems proposals a much better and foolproof means of restricting the use of vehicles by unauthorized users.

The advanced prototype assists as an impact us to drive future research, geared towards developing a more tough and surrounded real-time finger print founded reflex door lock systems in vehicles. The archetype structure can be separated into the following components: fingerprint study software module (using digital image appreciation algorithms) that receives fingerprints images; hardware interface section (operating a controller and a line control circuit) and the locking component. In real application, the fingerprint records will be verified using a fingerprint Sensor. The fingerprint Appreciation software allows fingerprints of legal consumers of the automobile to be registered in a folder in the form of kept examples in jpg, tiff, bmp, jpeg, tiff, gif type image accounts. So previously any user can unlock or explode the automobile, his fingerprint image is complemented beside the fingerprints in this record while operators with no contest in the databank are repudiated access to the structure. Biometric process requires the bodily presence of the somebody to be recognized. Thus, biometric gratitude systems deal greater safety and expediency than old-style methods of personal appreciation.
