Network based Android Mobile Controlled Door Security System

Security is important in many of the places like offices, institutions, libraries, laboratories etc. in order to keep data confidentially, so that no other unauthorized person could have an access on them. DoorLock android app is developed to reduce the human efforts for locking and unlocking the door. This paper presents a network based android mobile controlled door opening system which provides security which can be used for many banks, institutes and various organizations etc. This project is based on the today’s much-needed concept Automation System works with Android System. In this project, user login through the android application. To provide security to the places where much more confidentiality is required, this project includes the Random key technology. This technology is used to check whether the user is authorized or unauthorized. After authentication, signal is send to the microcontroller. Then using relay, door is opened automatically.
