ABSTRACT
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.
To add a fingerprint, just show the finger on the module and press the ADD key. Now the micro controller will send the ADD command to the module and the module will add it into the memory.
To delete the finger follow the same as above.
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
