Abstract
In today's world of the internet, security and comfort are the two eyes. The internet of things (IoT) helps us achieve this as this provides comfort and security to the user. The only thing that stands between us and the world outside us is the door so having proper security to safeguard our houses is important. Through the years, door locks have gone all the way from big, chunky complicated locks to contactless smart locks. Many doors in traditional systems had mechanical locks that had a limited number of keys. This article proposes Smart Door Unlock System based on Face Recognition, Fingerprint, RF card, Password and IoT to enhance the security. A camera sensor is used in this system to capture the face, and an image matching algorithm is used to detect the authenticated faces. Only the person whose face is matched can open the door. This system Fingerprint sensor is used to capture the finger and matching algorithm will be used to detect the fingerprint. So, limitation of managing keys will be resolved. The security system is also designed with the elderly in mind, as it is difficult for them to open the door manually.
