Real time security management using RFID, Biometric and Smart Messages

The proposed scheme presents the real time security managing methods that can be implemented using RFID, biometric and smart messaging. Entry doors to restricted areas are controlled using the biometric machines. Registered staff manages their entry through their RFID card, which is verified with biometric. The relay in the biometric reader will unlock the door if the verification is successful after comparing their duty roster timings. Staff details, time of entry/exit get recorded in the Oracle 10 g database which is used for their attendance processing. Any unauthorized attempt to open the door will get recorded immediately in the database and it activates the GSM modem to send SMS alert messages to the security staff mobile phones and to duty in charges mobile phones as recorded in the database. Interface to biometric reader is developed using software development kit (SDK), interface to GSM modem through AT commands and smart card programming & Oracle programming is made for server interface.
