FINGERPRINT BASED SECURITY SYSTEM Personal Safes are revolutionary locking storage cases that open with just the touch of your finger. These products are designed as secure storage for medications, jewelry, weapons, documents, and other valuable or potentially harmful items. These utilize fingerprint recognition technology to allow access to only those whose fingerprints you choose. It contains all the necessary electronics to allow you to store, delete, and verify fingerprints with just the touch of a button. Stored fingerprints are retained even in the event of complete power failure or battery drain. These eliminates the need for keeping track of keys or remembering a combination password, or PIN. It can only be opened when an authorized user is present, since there are no keys or combinations to be copied or stolen, or locks that can be picked. In this project the fingerprint module from Mixes Biometrics is used. It can store up to 750 finger prints on its own memory. It can be controlled through its serial port. The micro controller AT89S52 interacts with the module. You can add a fingerprint, Delete a fingerprint and identify the fingerprint. INTRODUCTION The era of biometrics In the 21st century the use of biometric based systems have seen an exponential growth. This is all because of tremendous progress in this field making it possible to bring down their prices, easiness of use and its diversified use in everyday life. Biometrics is becoming new state of art method of security systems. Biometrics are used to prevent unauthorized access to ATM, cellular phones , laptops , offices, cars and many other security concerned things. Biometric have brought significant changes in security systems making them more secure then before, efficient and cheap. They have changed the security system from fingerprints What is biometrics? Biometrics is the science of verifying the identity of an individual through physiological measurements or behavioral traits. Since biometric identifiers are associated permanently with the user they are more reliable than token or knowledge based authentication methods. Advantages of Biometrics Biometrics offers several advantages over traditional security measures. Some of Them are presented below. Accuracy and Security Biometrics based security systems are far most secure and accurate than traditional password or token based security systems. For example a password based security system has always the threat of being stolen and accessed by the unauthorized user. Further more the traditional security systems are always prone to accuracy as compared to biometrics which is more accurate. What are finger prints? Fingerprints recognition has been present for a few hundred years. Due to tremendous research this field has reached such a point where the purchase of fingerprint security system is quite affordable. For this reason these systems are becoming more widespread in a variety of applications. How fingerprint scanners work A fingerprint scanner can store an image of your fingerprint and match the basic patterns that make up a fingerprint (arch, loop and whorl), but storing the image could be a security risk, and the 500 ppi most sensors use results in large image files. Instead, most systems store a mathematical representation of the characteristics in the fingerprint, called minutiae, based on where the ridges in the fingerprint start and stop, split or join together. Storing the details of a fingerprint in the system is known as registering or enrolling. You scan the same finger three or four times (or more if you’re not getting a good scan), so that the software can calculate minutiae for enough areas of your finger to be sure of recognizing it. Start by pressing the first joint of your finger or thumb against the scanner, press firmly but not too hard, keep your finger straight and move it smoothly. If you share your PC, everyone can scan their own fingerprints for access. |
