Secure E-Payment Method Based on Visual Cryptography

In recent time there is a rapid growth in the online shopping market. With ever increasing popularity of the online shopping, debit or credit card fraud and personal information security are major concerns. Phishing and identity theft are common threats to online shopping. Phishing is a method of stealing personal confidential information, such as username, password, credit card details, from legitimate user. In this paper, we have proposed a credit card payment method using visual cryptography. Visual cryptography is applied to captcha generated by the merchant during the registration phase, to a text file containing credit card details sent by the Merchant Plug-In to the Card Provider Directory Server, and to Quick Response Code containing One Time Password that is used to authorize payment transaction. The purpose of this method is to improve e-payment security, especially in terms of authentication, authorization, and confidentiality. This method provides limited credit card details to the merchant and prevents phishing and identity theft so that the customer's confidence will increase.
