The proposed Image-Based Password Authentication System for Illiterates with Touch Screen and Face Recognition is designed to provide a simple, user-friendly, and secure access control system for homes, poultry farms, offices, and industrial applications. Unlike conventional password systems that require remembering letters, numbers, or special characters, this system uses a sequence of images as a password, making it easier for illiterate and elderly users to operate. A touch screen is used to select the predefined images, and the microcontroller verifies the entered image sequence. If the password is correct, the door is automatically opened using a DC motor. If an incorrect password is entered, a buzzer provides an alert and the system can send an SMS notification to a predefined mobile number through the GSM modem. The system also incorporates face recognition technology to provide an additional level of security. A LAPTOP camera captures the user's facial image, which is processed and compared with the stored facial database using MATLAB software. The identified facial information is communicated to the microcontroller for authentication and access control. An LCD or graphical display provides visual information regarding the system status, while the buzzer provides audible alerts during unauthorized access attempts. By combining image-based password authentication, touch screen interfacing, face recognition, GSM-based SMS alerts, and automatic door control, the proposed system provides a convenient, accessible, and reliable security solution for users who may find conventional text-based authentication difficult.
