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.

Fraud scandals can create incentives to change managers in an attempt to improve the firm’s performance, recover lost reputational capital, or limit the firm’s exposure to liabilities that arise from the fraud. It also is possible that the revelation of fraud creates incentives to change the composition of the firm’s board, to improve the external monitoring of managers, or to rent new director...

A fraud survey found that 75 percent of the 459 responding organizations experienced some form of fraud during the prior 12 month period [1]. 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...

We analyze the strategic decision of firms to voluntarily certify corporate social responsibility (CSR) practices in a context where other firms can falsely pretend to be socially responsible. Equilibrium outcomes are crucially determined by consumers' beliefs about the credibility of firms' CSR claims, which depend in turn on the (expected) fines for fraud. First, we show that an increase in s...

Distance bounding protocols are an effective countermeasure against relay attacks including distance fraud, maa fraud and terrorist fraud attacks. Reid et al. proposed the rst symmetric key distance bounding protocol against maa and terrorist fraud attacks [1]. However, [2] claims that this is only achieved with a (7/8) probability of success for maa fraud, rather than the theoretical value...

The Fraud Bill, which received Royal Assent on 8 November 2006, created an offence of fraud in English criminal law which marks a departure of utmost significance from the approach adopted hitherto, whereby a number of related offences cover behaviour deemed to amount to fraud. To mark the passage of the Fraud Act 2006 into law, this article examines the references which were made during its co...

Loan fraud is a critical factor in the insolvency of financial institutions, so companies make an effort to reduce the loss from fraud by building a model for proactive fraud prediction. However, there are still two critical problems to be resolved for the fraud detection: (1) the lack of cost sensitivity between type I error and type II error in most prediction models, and (2) highly skewed di...
