This paper discusses the status of research on detection of fraud undertaken as part of the European Commission-funded ACTS ASPeCT (Advanced Security for Personal Communications Technologies) project. A first task has been the identification of possible fraud scenarios and of typical fraud indicators which can be mapped to data in toll tickets. Currently, the project is exploring the detection ...

Within the business context of mining the data to achieve...

Previous studies on mobile ad fraud detection are limited to detecting certain types of ad fraud (e.g., placement fraud and click fraud). Dynamic interactive ad fraud has never been explored by previous work. In this paper, we propose an explorative study of ad fraud in Android apps. We first created a taxonomy of existing mobile ad fraud. Besides static placement fraud, we also created a new c...

Fraud detection is a key activity with serious socioeconomical impact. Inspection activities associated with this task are usually constrained by limited available resources. Data analysis methods can provide help in the task of deciding where to allocate these limited resources in order to optimise the outcome of the inspection activities. This paper presents a multi-strategy learning method t...

This thesis introduces a financial simulation model covering two related financial domains: Mobile Payments and Retail Stores systems. The problem we address in these domains is different types of fraud. We limit ourselves to isolated cases of relatively straightforward fraud. However, in this thesis the ultimate aim is to introduce our approach towards the use of computer simulation for fraud ...
