The objective of this project is to design and implement a Secure ATM Authentication System using multi-level verification techniques. The system enhances transaction security by integrating PIN validation, OTP verification, and behavioral checks, helping students understand layered security models and secure authentication mechanisms.
Study ATM authentication workflow and common security threats.
Prepare Software Requirement Specification (SRS) and system security model.
Design system architecture with authentication and verification layers.
Create database schema for users, ATM cards, PIN data (hashed), transaction logs, and OTP records.
Implement secure user login using card number and PIN verification with hashing techniques.
Integrate second-level authentication such as OTP generation and validation (simulation).
Implement third-level verification such as transaction limit checks or behavioral pattern validation.
Develop account lock mechanism after multiple failed attempts.
Implement secure session handling and transaction timeout functionality.
Simulate ATM interface for balance inquiry, cash withdrawal, and mini statement generation.
Apply encryption techniques to protect sensitive transaction data (MCA-level enhancement).
Maintain audit logs for authentication attempts and transactions.
Perform security testing including brute-force prevention and validation testing.
Generate transaction reports and authentication logs.
Prepare documentation including ER diagrams, flowcharts, security architecture, and test cases.
Deploy system locally and demonstrate complete authentication workflow.
