MOBILE FRAUD DETECTOR Chapter 1 Abstract This paper discusses the status of research on detection of fraud undertaken in mobile system. 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, this project is exploring the detection of fraudulent behaviour based on a combination of absolute and differential usage. Three approaches are being investigated: a rule-based approach, and two approaches based on neural networks, where both supervised and unsupervised learning are considered. Special attention is being paid to the feasibility of the implementations. B.V.B. College Of Engg. & Tech.,Hubli 3

MOBILE FRAUD DETECTOR Chapter 2 Introduction It is estimated that the mobile communications industry loses several million customers per year due to fraud. Therefore, prevention and early detection of fraudulent activity is an important goal for network operators. It is clear that the additional security measures taken in GSM and in the future UMTS (Universal Mobile Telecommunications System) make these networks less vulnerable to fraud than the analogue networks. Nevertheless, certain types of commercial fraud are very hard to preclude by technical means. It is also anticipated that the introduction of new services can lead to the development of new ways to defraud the system. The use of sophisticated fraud detection techniques can assist in early detection of commercial frauds, and will also reduce the effectivity of technical frauds. The remainder of this paper is organized as follows: Chapter 1 discusses the identification of possible fraud scenarios and of fraud indicators Chapter 2 discusses the general approach of user profiling, Chapter 3 presents the rule-based approach Chapter 4 presents the neural net-based approach to fraud detection.

MOBILE FRAUD DETECTOR Chapter 3 Possible frauds and their indicators 3.1 Possible Frauds: Two way Classification of Frauds: The first stage of the work consists of the identification of possible fraud scenarios in telecommunications networks and particularly in mobile phone networks. These scenarios have been classified by the technical manner in which they are committed; also an investigation has been undertaken to identify which parts of the B.V.B.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
