Enhancement of security with the help of real time authentication and one time password in e-commerce transactions

As e-commerce industry is growing rapidly, security issues become more crucial. One of the most important factors in e-commerce transactions and payments is security. While information about customers and their transactions is extremely sensitive, privacy protection is very vital. So, privacy policies to address customer data security are required. At the same time, authentication is one of the most important security requirements and prevents fraud and theft in e-payment transaction. Online biometric authentication is the best solution for preventing false authentication and identity theft. This research reviews authentication ways, and proposes two online biometric authentication methods with credit cards together virtual password concept. The proposed methods utilize credit card and biometric techniques. The first authentication method uses SSL protocol together fingerprint sample of biometric techniques and is suitable for less sensitive financial transactions. The second uses 3_D secure protocol together iris sample of biometric techniques with help of one-time password concept, so is very suitable for more sensitive financial transactions. Finally, the proposed solutions are analyzed using available methods and solutions.
