Paper Details

The most common challenged in today’s world is security of lives and properties. This has necessitate the need toconcentrate effort towards improving the security frame work currently in existence and the need to build new ones wereapplicable. In this research a comprehensive literature study and implementation related to the various door locks and gatesecurity systems in areas such as home, vehicles, banks and industries where possibilities of incursion are increasing day byday is realized. The input of the system in this design has two stages of authentication, stage 1 is the screen pattern inputtedvia the TFT touch screen and stage 2, is the knock pattern inputted via the piezoelectric sensor. The TFT touch screen andpiezo sensor are connected directly to the microcontroller and both stages have to be verified before the Arduinomicrocontroller sends an electric signal to the DC motor which turns the deadbolt and unlocks the safe. The user first inputshis recorded screen pattern, and if correctly entered, he next enters the knock pattern. The green LED which is normally onblinks to indicate normal system functionality. Both the screen pattern and knock pattern have to be correctly inputted beforethe safe is unlocked. If the wrong screen pattern is entered, the user is told to try again and if the wrong knock pattern isentered, a red LED blinks and the user told to try again. As a means of backup and extra security measure an androidapplication is incorporated in the design to enable reset and easy access by the rightful individual of the securityarchitecture. The application installed on an android device which is then connected to the microcontroller in case of afailure or system lock down due to wrong patterns being inputted more than three times. If more than 3 wrong patterns areinputted, the system locks down permanently until the pattern entries are reset with the user’s android application and PIN.To record a new pattern, the user first resets the pattern entry by inputting a PIN on his android device after which herecords a new screen pattern, presses and holds the push button switch to record a new knock pattern. The recorded knockpattern is played back to the user after recording by rhythmic blinking of both the red and green LEDs.
