BIOMETRIC BACK COVER FOR SMART PHONES WITH IDENTITY VERIFICATION

Our identities may be largely determined by our social relationships with people in our environment. In the mobile phone (and smart phone) era, it is indispensable for building and maintaining social relationships. Security is one of the unique criteria where every mobile user should think about it. Nowadays, there are many varied characteristics involved in the security of the mobiles like Patterns, Number locks and Biometric Security like finger prints. But some of the mobile phones lack this type of facility like finger prints. Our project deals with accessing the apps with the finger print of the users which are inhered in the thin sheet which will be placed behind the mobile phones. It utilizes a Bluetooth HC-05, biometric sensor of version GT511C3 and a Arduino Nano Board At mega 328p. The Bt-Terminal app is primarily used in which it gives the security to access it and the finger print is need to be placed in the sensor and wait for the authentication. Once the accessing is granted a light will be displayed. If there is some error in placing the finger or any unauthorized person places the finger, then within a threshold time limit the app notifies with an acknowledgement.
