The dynamics of humans and the acceleration of web technologies resulting from the increased hardware performance coupled up with inexpensive computing, credit card fraud and cybercrimes in general have become more and more sophisticated. Competent algorithms and methodologies that detected and prevented fraudulent use of credit cards ten years ago are no more very effective today. Rogue applications, password sniffers and generators, cyberpunks etc. are all on the rise. Quest for e-commerce deployment on the other hand is on ascend. It is therefore imperative, as a matter of collective responsibility, to research for lasting solutions to fraudulent use of credit cards which is now a threat to ecommerce Payment Systems. Though a number of existing remedies to the problem exist, researchers all over the world keep working to improve the existing strategies since the canker is unabated. This research, in this direction, uses a two layer approach to evaluate an incoming credit card transaction to establish whether it is genuine or fraudulent.
