Introduction The main aim of this project is to provide a security systemfor illiterates. Since the images are more easily to recalling in comparison to string of character. The images are displayed on touch screen ,one can enter correct sequences of images get authenticated. Gives exposure about how touch screen interface in our practical life. It can be easily installed in industries ,houses ,poultry formfor security . 4. Block Diagram 5. Hardware Description The major building blocks of this project are: Regulated power supply with voltage regulator Micro controller Touch screen sensor Stepper motor Buzzer 6. Power supply 7. Microcontroller (PIC16F72) 1. 2.3. a.The microcontroller used in this project is PIC16F72. The PIC families of microcontrollers are developed by Microchip Technology Inc. PIC microcontrollers: PIC12CXXX 12/14-bit program word .b. c. d.PIC 16C5X 12-bit program word . PIC16CXXX and PIC16FXXX 14-bit program word . PIC17CXXX and PIC18CXXX 16-bit program word. 8. Technologies of Touch Screen There are a number of types of touch screen technology. 1. Resistive 2. Surface acoustic wave 3. Capacitive 4. Surface capacitance 5. Projected capacitance 6. Infrared 7. Strain gauge 8. Optical imaging 9. Working of Resistive Touch screens 1. Polyester Film 2. Upper Resistive 3.4. 5. 6.7.circuit Layer Conductive ITO (Transparent Metal Coating). Lower Resistive Circuit Layer Insulating Dots Glass/AcrylicSubstrat -e Touch screen 10. Continue. The contact can closethe switch an generated Voltages. Touch screen controller convert it into (X,Y) Co-ordinate system and hence the position of touch is sense by controller easily. 11. Stepper motor It is gear based motor. The stepper motor are connectedwith ULN2803 driver. When the correct password entered the lock attached to the motor is open. 12. Buzzer Basically it works as sound sourcebased on piezoelectric diaphragm. It is consists of electrode ,when dc voltage applied across electrode produces sound. To switch on buzzer -high 1 To switch off buzzer -low 1 13. Advantages Easily recalling. Image based password is more secure than text basedpassword. Less vulnerable. Easily installation method. 14. Disadvantages Since it is totally based on password hence shouldersurfing can reduce the security of system. Taken more prevention for touch screen safety. 15. Procedural steps for compilation, simulation and dumping PIC compiler is used for programming. After programming run the programs, it generated a.hex extension file. The .hex extension file are dumping into microcontroller using PIC kit programmer. 16. Conclusion Image password is easily remember than string of character password. Image password is more secure than text based password. Less vulnerable by attacker. Know the exposure of touch screen interface in practical life. Shoulder surfing reduce the security of system. 17.
