Abstract
A new methodology in temporal networks is presented for the use of fraud detection systems in the banking sector. Standard approaches of fraudulence monitoring mainly have the focus on the individual client data. Our approach will concentrate on the hidden data produced by the network of the transaction database. The methodology is based on a cycle detection method with the help of which important patterns can be identified as shown by the test on real data. Our solution is integrated into a financial fraud system of a bank; the experimental results are demonstrated by a real-world case study.
