Abstract

With the increasing usage of credit cards, secure requirements for handling credit card payment have become more critical. Today, it is being deployed for a wide application services in mobile commerce over public networks. Based on the security of Naor-Shamir's visual cryptography, Diffie-Hellman key agreement scheme and symmetric cryptosystems, we propose a new credit card payment scheme using mobile phones based on visual cryptography. Compared with traditional credit card payment methods', the proposed scheme can provide more secure communication for many electronic commerce transactions.
