Digital Door Lock on the Access Control System using OTP-based User Authentication using Raspberry Pi
Abstract
The access control system based on OTP is proposed to complement the drawbacks of the user authentication mechanism such as a digital door-lock and mechanical door-lock based. The proposed method does not need administrator's help to access the facility if the user must know OTP and has a registered mobile phone. The OTP is generated and sent to the user's mobile phone whenever the user requests to access facility. The proposed system can solve the problems of loss or theft in conventional access control system. The proposed system is able to enhance the user authentication method by using combination of card input method and number input based on the value of OTP. Also in these system camera is attached, whenever unknown person is entered in the house then PIR sensor sense that person and alarm will be sounded. Then user entered password and open the door
