As ATM cards, credit cards, and mobile banking become more convenient, online banking is becoming more popular around the world. Usernames, passwords, CVVs, and OTPs, although traditionally used for authentication, are susceptible to security vulnerabilities. The vulnerabilities of these systems can be exploited at will, resulting in unauthorized access to sensitive financial information. Biometric authentication, particularly the recognition of iris patterns, is proposed as a solution to these security challenges. Through the combination of traditional authentication methods and biometric traits, this system offers an additional layer of security. A secure database stores iris patterns that can be compared to a secure database to verify who is authorized to complete transactions. This provides a dependable solution for modern banking security.
