1.A Distributed Database Architecture for Global Roaming in Next-Generation Mobile Networks
(JAVA)
The next-generation mobile network will support terminal mobility, personal mobility, and service provider portability, making global roaming seamless. A location-independent personal telecommunication number (PTN) scheme is conducive to implementing such a global mobile system. However, the nongeographic PTNs coupled with the anticipated large number of mobile users in future mobile networks may introduce very large centralized databases. Th ....etc

DISTRIBUTED DATABASE ARCHITECTURE FOR GLOBAL ROAMING IN FUTURE MOBILE NETWORKS




Introduction
The next-generation mobile network will be an integrated global system that will provide heterogeneous services across network providers, network backbones and geographical regions. Global roaming is a basic service of the future mobile networks where terminal mobility, personal mobility and service provider portability must be supported. A nongeographic personal t ....etc

CREDIT CARD FRAUD DETECTION USING HIDDEN MARKOV MODELS
Abstract: Now a day the usage of credit cards has dramatically increased. As credit card becomes the most popular mode of payment for both online as well as regular purchase, cases of fraud associated with it are also rising. In this paper, we model the sequence of operations in credit card transaction processing using a Hidden Markov Model (HMM) and show how it can be used for the detection of frauds. An HMM is initially trained with the normal behavior of a cardholder. If an incoming cre ....etc

Introduction
The mobile telecommunications sector is severely affected by security threats, with fraud attacks in roaming contexts one of the greatest causes of financial losses in the industry every year. Because of the evolution of the services provided by telecommunications operators, more and more elaborate attack techniques are being developed by international fraudsters. These activities impact directly on the companies involved and have repercussions regarding potential increases in tariffs. Therefore, it ....etc
