Abstract
Fingerprint verification is one of the most reliable personal identification methods in biometrics. Most doors are
controlled by the biometric technique. The idea of this technique is to enable automatic verification of identity of one
or more behavioral and/or physiological characteristics of a person. Recently, biometric methods used for personal
authentication utilize features as the face, the voice, the hand shape, the finger print, and the iris patterns of an
individual. Each method has its own advantages based on their usability and security. This biometric access control
system provides authorized individuals for safe and secure access in and out of organizations. This system is mainly
focus on the security purpose of organizations.
The uses of biometric based systems have seen an exponential growth in recent years. This is 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 is used to prevent unauthorized
access to bank locker, jewelry shop and many other security concerned things. The applications of SMS/GSM
Based security systems are quite diverse. There are many real life situations that require control of different
devices remotely and to provide security.
And also system has to send message through SMS using GSM to other authorized people who away from the
restricted areas. This combination of task improves the security of the system.
Methodology
It mainly consists of four sections.
• Password, Fingerprint identification and verification section.
• Micro controller section.
• Message passing and storing data into database.
• Door section.
In this proposed work keypad is used to input the password by the user. If the password is valid LCD display the
success message and allow giving a finger print reader to the user. If not valid password LCD display the error
message. Then finger print module is used to identify the individuals. If the password and finger print match the
request message pass to other authorized persons. If not match LCD display the error message. Based on the other
authorized person’s reply then door will unlock. If not send the correct message the door will not unlock.
