In the year 2009 several data privacy scandals have hit the headlines where major corporations had a legitimate need for detecting fraud conducted by their own employees, but chose inappropriate measures for data screening. This contribution presents architectures and pseudonymization technology for privacy compliant fraud screening or fraud detection, in order to reduce the number of undiscove...

Although computer fraud continues to be a thorn in the side of many organizations, fresh perspectives to addressing this type of crime are rare.

As the usage of credit card has increased the credit card fraud has also increased dramatically. Existing fraud detection techniques are not capable to detect fraud at the time when transaction is in progress. Improvement in existing fraud detection is necessary. In this paper Hidden Markov model is used to detect the fraud when transaction is in progress. Here is shown that hidden markov model...

Given the requirements of fast processing and the complexity of RF ranging systems, distance bounding protocols have been challenging to implement so far; only few designs have been proposed and implemented. Currently, the most efficient implementation of distance bounding protocols uses analog processing and enables the prover to receive a message, process it and transmit the reply within 1 ns...

With the developments in the information technology, fraud is spreading all over the world, resulting in huge financial losses. Though fraud prevention mechanisms such as CHIP&PIN are developed for credit card systems, these mechanisms do not prevent the most common fraud types such as fraudulent credit card usages over virtual POS (Point Of Sale) terminals or mail orders so called online credi...

The Association of Certified Fraud Examiners (ACFE) estimates 6 percent of revenues are lost due to theft by employees and that small businesses suffer disproportionate losses because of limited resources devoted to fraud detection [2]. Most employee thef...

This paper discusses the current status of research on fraud detection undertaken as part of the European Commission-funded ACTS ASPeCT (Advanced Security for Personal Communications Technologies) project, by Royal Holloway University of London. Using a recurrent neural network technique, we uniformly distribute prototypes over toll tickets, sampled from the U.K. network operator, Vodafone. The...
