Smart security system for door access based on unique authentication

Security is a prime aspect of concern in order to maintain confidentially of our home, work places and to avoid intrusion of unauthorized persons. In voice password and biometric based authentication door locking system, authentication using the unique identification like biometric and voice recognition plays a vital role to provide high level of security. The finger ridges of individual do not match with any other finger ridges and an individual’s voice cannot be impersonated with accuracy.This paper proposes a smart voice password and biometric based security system for door locking in smart homes. To enhance the security, in place of conventional door locking system, a finger print sensor along with a micro phone are used to authenticate, i.e. to lock and unlock the doors [1]. The data base will maintain the data of the persons who tried to access the door. The entire system is controlled by the Raspberry pi 3 B+ processor. PIWHO soft ware is used for the purpose of voice recognition. Door access may be provided to the registered users based on his voice pass word and thumb impression. Door will be opened only when both the factors are satisfied, otherwise buzzer will be activated and the authorized person will receive an SMS alert message.
