    Get PDF
    Nigeria was described as the fastest growing telecoms nation in Africa and the third in the World. The country had experienced a phenomenal growth from a teledensity of 0.49 in 2000 to 25.22 in 2007. This trend has brought about a monumental development in the major sectors of the economy, such as banking, telecoms and commerce in general. This paper presents the level of adoption of ICT in the banking sector and investigates the prospects of m-Commerce in Nigeria based on strengths, weaknesses, opportunities and threats (SWOT) analysis. Findings revealed that all banks in Nigeria offer e-Banking services and about 52% of the offer some forms of m-Banking services. The banks and the telecoms operators have enormous potentials and opportunities for m-Commerce but the level of patronage, quality of cell phones, lack of basic infrastructure and security issues pose a major threat to its wide scale implementation

    Nouveaux instruments de paiement: une analyse du point de vue de la banque centrale

    Les Ă©volutions technologiques apportent des solutions de paiement de dĂ©tail innovantes (paiements par tĂ©lĂ©phone mobile par exemple). Ce cahier d'Ă©tudes aborde le sujet de la qualification des nouveaux instruments de paiement. Il contient une analyse basĂ©e sur la dĂ©finition des diffĂ©rentes formes de monnaie (dont la monnaie Ă©lectronique) et des instruments de paiement, dans le cadre gĂ©nĂ©ral des paiements et des systĂšmes de paiement, ainsi que dans leur contexte rĂ©glementaire national et europĂ©en. Parmi les nouvelles possibilitĂ©s technologiques, les systĂšmes de tĂ©lĂ©phonie mobile offrent des atouts techniques et commerciaux pour le dĂ©veloppement de solutions de paiements mobiles d'ambition ubiquitaire. Comme pour certaines solutions Ă©lectroniques de paiement de dĂ©tail, les paiements mobiles sont l'occasion pour des entrepreneurs non liĂ©s au secteur bancaire de devenir des prestataires de paiement de masse. L'observation des caractĂ©ristiques et des modĂšles de solutions de paiement Ă©lectroniques et mobiles permet d'identifier si cette participation tend Ă  ĂȘtre coopĂ©rative ou concurrentielle avec les banques. S'agissant des paiements, la garantie de sĂ©curitĂ© est primordiale. L'utilisation de rĂ©seaux de tĂ©lĂ©communication ouverts (la tĂ©lĂ©phonie mobile, Internet, etc.) gĂ©nĂšre des craintes supplĂ©mentaires liĂ©es Ă  la fraude et Ă  la sĂ©curitĂ©. Une partie est consacrĂ©e aux risques associĂ©s aux paiements Ă©lectroniques et Ă  leurs composantes de sĂ©curitĂ©. Finalement sont abordĂ©es les diffĂ©rentes initiatives publiques et privĂ©es qui ont pour but de promouvoir la sĂ©curitĂ© et l'efficience des paiements Ă©lectroniques. Le SystĂšme europĂ©en de banques centrales est assez entreprenant en la matiĂšre.

    Analysis of roles and position of mobile network operators in mobile payment infrastructure

    Get PDF
    A number of different mobile payment solutions have been presented the last decade. The phone subscription with its security mechanisms are used for user identification and payments. This is the case for SMS based payment and ticketing systems that are getting more and more popular. However, there are other ways to implement a Trusted Element (TE) , where a SIM card architecture is only one. It can be in the mobile phone, as a separate integrated circuit, as an optional customer deployed plug-in device (e.g., microSD) or be running as an application on a server existing entirely as software. In this paper we analyze what roles and responsibilities different actors have in different types of mobile payments solutions. The main focus is on the implications for the mobile operator business. It turns out that new types of intermediary actors in most cases play an important role. Sometimes mobile operators are not even involved. The emergence of new payment together with other non-SIM card based TE solutions opens up for many different market scenarios for mobile payment services. --

    A COMPARISON OF THE MOST POPULAR ELECTRONIC MICROPAYMENT SYSTEMS

    Get PDF
    The buying and selling of products or services over electronic systems such as the Internet and other computer networks is known as electronic commerce. In order to reduce the costs of electronic transactions, when one exchanges cheaper goods and services, specific payment protocols must be used. These protocols are actually the foundation for electronic micropayments, which implement simplified and cheaper schemes intended for small value transactions. In this paper we shall present and compare the main characteristics of the most popular micropayment systems used in both face-to-face and remote commerce.e-commerce, micropayment, security, encryption, Chipper, GeldKarte, Mondex, Proton, First Virtual, NetBill, KLELine, Odysseo, MicroMint

    Strengthening e-banking security using keystroke dynamics

    Get PDF
    This paper investigates keystroke dynamics and its possible use as a tool to prevent or detect fraud in the banking industry. Given that banks are constantly on the lookout for improved methods to address the menace of fraud, the paper sets out to review keystroke dynamics, its advantages, disadvantages and potential for improving the security of e-banking systems. This paper evaluates keystroke dynamics suitability of use for enhancing security in the banking sector. Results from the literature review found that keystroke dynamics can offer impressive accuracy rates for user identification. Low costs of deployment and minimal change to users modus operandi make this technology an attractive investment for banks. The paper goes on to argue that although this behavioural biometric may not be suitable as a primary method of authentication, it can be used as a secondary or tertiary method to complement existing authentication systems

    Mobile operators as banks or vice-versa? and: the challenges of Mobile channels for banks

    Get PDF
    This short paper addresses the strategic challenges of deposit banks, and payment clearinghouses, posed by the growing role of mobile operators as collectors and payment agents of flow of cash for themselves and third parties. Through analysis and data analysis from selected operators , it is shown that mobile operators achieve as money flow handlers levels of efficiency , profitability ,and risk control comparable with deposit banks ñ€“ Furthermore , the payment infrastructures deployed by both are found to be quite similar , and are analyzed in relation to strategic challenges and opportunities This paves the way to either mobile operators taking a bigger role ,or for banks to tie up such operators to them even more tightly ,or for alliances/mergers to take place ,all these options being subject to regulatory evolution as analyzed as well . The reader should acknowledge that there is no emphasis on specific Mobile banking (M-Banking) technologies (security, terminals, application software) , nor on related market forces from the user demand point of view.banking;industry structure;mobile networks;operational cash flow;regulations;transaction systems

    A Secure Mobile-based Authentication System

    Financial information is extremely sensitive. Hence, electronic banking must provide a robust system to authenticate its customers and let them access their data remotely. On the other hand, such system must be usable, affordable, and portable.We propose a challengeresponse based one-time password (OTP) scheme that uses symmetric cryptography in combination with a hardware security module. The proposed protocol safeguards passwords from keyloggers and phishing attacks. Besides, this solution provides convenient mobility for users who want to bank online anytime and anywhere, not just from their own trusted computers.La informaciĂł financera Ă©s extremadament sensible. Per tant, la banca electrĂČnica ha de proporcionar un sistema robust per autenticar als seus clients i fer-los accedir a les dades de forma remota. D'altra banda, aquest sistema ha de ser usable, accessible, i portĂ til. Es proposa una resposta al desafiament basat en una contrasenya Ășnica (OTP), esquema que utilitza la criptografia simĂštrica en combinaciĂł amb un mĂČdul de maquinari de seguretat. AmĂ©s, aquesta soluciĂł ofereix mobilitat convenient per als usuaris que volen bancĂ ria en lĂ­nia en qualsevol moment i en qualsevol lloc, no nomĂ©s des dels seus propis equips de confiança.La informaciĂłn financiera es extremadamente sensible.
