This document proposes a picture password authentication system using a touchscreen for illiterate users. The system would allow users to create passwords by touching images on the touchscreen in a predefined combination. If the user touches the images in the correct sequence, the microcontroller will authenticate them and grant access to appliances connected to relays. This technique aims to make passwords easier for illiterate users to remember compared to text passwords. A block diagram shows the main components would include a microcontroller, touchscreen module, LCD display, power supply, and relays connected to devices.

Document Version 1.0 Document ID TSS15W004 Document Title Project Abstraction Specification Project Abstraction Specification Private & Confidential 1/2 Image based Password authentication for Illiterates with touch screen ABSTRACT: The authentication is the key issue everywhere like industries and homes. The commercial authentication methods involves the password based and conventional lock based authentication. The main drawback with this commercial methods ia remembering the passwords and carrying the keys. The passwords will be difficult to remember in case of the authenticated person is illiterate. They can’t remember the letters and digits as they don’t know them. The project is aimed to implement an authentication system for industrial/house hold applications for accessing the appliances by using a ‘Picture Password’ technique. Here we are using a touch screen module to interface with microcontroller. The touch screen input is a smart technique for getting the inputs with a finger touch recognition. The touch screen module will be having some images on it. By using this images, we can create a password combination with the images. The following figure shows a sample picture combination.

If the password is matched, then the user will be authenticated and allowed to access the appliances. The pictures will be easy to remember rather than a password for illiterates.
