The rapid growth of the Internet over the past several years has been fueled mainly by the sharing and transferring of vast amounts of information. This comes from the increased use of the Internet for commercial business transactions, which gives birth to electronic fraud (e-fraud) problems. M ost business transactions are concerned with three types of security. First, they wish to ensure the positive identity of the customer, and that all transactions are sent to the right customer. Second, they want to protect sensitive customer information, such as credit card numbers, bank account numbers, or other personal and financial data. And third, they want to make sure that the data is not altered or changed as it is transmitted across the Internet. This study seeks to redress this situation through the development of a model of the process of e-fraud, using the existing literature as a guide. Based on a broad definition of both e-crime and e-fraud, the resultant model describes the five key elements of e-fraud: perpetrator, mode of attack, target system, target entity and impact. It is envisaged that the model will allow the mechanics and context of e-fraud to be more fully understood, thus assisting in the development and implementation of effective countermeasures.

Abstract:Mobile agent is gaining attention in the research community because of its potential to replace traditional client-Server application in computer network system. Mobile agent has the ability to migrate autonomously from one server to another server as specified in its itinerary in computer network. Areas where mobile agent profit includes network management, information retrieval and electronic commerce. Mobile agent can be delegated to carry out all stages that are involved in electronic commerce such as Product brokering, Merchant brokering, Negotiation and Purchase. However there are security vulnerability issues with mobile agent system such as the need to ensure confidentiality of information of the agent from malicious parties, integrity of the data of the agent and non-repudiation from parties involves in the transactions. Security measure by agent developers has been mobile cryptography. This research combines Elliptic curve cryptography (ECC) and Steganography known as cryptosteganography to secure its agent. The agent was developed using PHP 5.0, Javascript, HTML, Wampserver and MySQL. The system was tested on a local area network with six computer systems, one of the computers represent client and the other five as servers. Performance evaluation was carried out to test for execution time and workload effect on the system. The result was compared with the existing secured agent-based electronic commerce systems in term of response time. The result shows that the proposed security is faster than RSA but a little slower than ECC only. A trade off was observed between a more secured system and response time of the system.

Nigeria as a democratic nation in Africa uses conventional paper ballot election system for more than two decades now. Enquiry with proof shows that this conventional election system has lost popularity among the people as it has drawbacks, which call for replacement. Therefore, this paper aims in introducing Biometric electronic voting system, its step-by-step operation, and define a set of requirement to achieve the operation, which are better than conventional paper ballot system in terms of accuracy, security wise, and authentication.
