The objective of this project is to design and develop a smart authentication system using a QR code–based login mechanism. The system eliminates password dependency, enhances login security, and helps students understand token-based authentication, secure session handling, and modern login technologies.
Study limitations of traditional username-password authentication systems.
Analyze QR code–based authentication concepts and real-world use cases.
Prepare Software Requirement Specification (SRS) and authentication workflow documentation.
Design system architecture including web application, mobile scanner module, and authentication server.
Create database schema for users, login sessions, QR tokens, token expiry, and authentication logs.
Implement secure user registration with basic identity verification.
Develop QR code generation logic containing time-bound encrypted login tokens.
Implement QR code scanning module (mobile app or simulated scanner).
Validate scanned tokens on the server and authenticate user sessions securely.
Implement token expiration and one-time usage to prevent replay attacks.
Develop fallback authentication method such as OTP or PIN if QR login fails.
Implement secure session management and automatic logout features.
Maintain audit logs for login attempts and token validations.
Apply input validation and secure coding practices to prevent common vulnerabilities.
Perform unit testing, integration testing, and authentication flow testing.
Prepare documentation including ER diagrams, QR login flowcharts, test cases, and deployment steps.
Deploy the system locally or on a cloud platform for demonstration.
