    Secure electronic payment systems are of paramount importance in supporting the further development of electronic commerce. While an electronic payment system must meet the needs of both businesses and consumers, most of the current electronic payment schemes are based on the traditional methods of finance we are familiar with in the western world. The main aim of this thesis is to develop new secure electronic payment schemes that satisfy the requirements posed by Islamic finance principles, which forbid the payment or receipt of interest. After providing a generic model for an electronic payment system, a description of some of the properties that distinguish the various types of electronic payment systems is given. The thesis then reviews examples of electronic payment schemes that are relevant to this thesis. The main concepts underlying Islamic finance are also introduced. The main contribution of this thesis is to propose four protocols that can be used to conduct secure electronic commerce transactions in a way that is consistent with Islamic financial principles. In the theme of developing new schemes to enable new participants to benefit from electronic payments, we also propose a simple and secure interpersonal payment system. EMV compliant IC cards have been developed to secure traditional Point of Sale debit/credit transactions. In this thesis, we propose a way to use EMV-compliant cards to conduct an electronic Murabaha transaction with the goal of exploiting the widespread deployment of EMV cards. The Internet is the platform on which most electronic commerce transactions are performed. To build upon this base, this thesis presents a method for conducting a secure electronic Murabaha transaction using the Internet. The increase in ownership of mobile phones suggests that they can be an effective means of authorising payment in electronic commerce transactions, offering security and convenience advantages by comparison with on-line payments conducted using PCs only. Therefore, this thesis proposes a new GSM-based payment system that enhances the security of Internet Murabaha transactions. Although many charities have a web presence, almost all of them have been designed to accept credit cards as the only means for making donations. The anonymity requirements of many donors, however, make the existing means of donation inappropriate for them. A new scheme supporting anonymous donations and distribution of these donations is therefore proposed

    Pendekatan konstruktif adalah pendekatan pengajaran dan pembelajaran yang berpusatkan pelajar manakala inovasi pengajaran pula dikaitkan dengan kaedah pengajaran yang terbaru demi mengukuhkan pemahaman pelajar. Pembelajaran berasaskan pendekatan konstruktif merupakan elemen yang penting dan perlu difahami oleh guru-guru bagi memantapkan proses pengajaran dan pembelajaran sesuai dengan peredaran masa dan menjayakan proses tranformasi pendidikan negara. Objektif kajian ini dijalankan untuk mengenal pasti pemahaman guru-guru bahasa Melayu berkaitan inovasi, mengenal pasti perbezaan yang wujud antara guru lelaki dan guru perempuan dalam mengamalkan inovasi, pengkaji juga melihat adakah wujud perbezaan antara guru baru dan guru yang sudah berpengalaman dalam aspek mengaplikasikan inovasi serta mengenal pasti kekangan-kekangan yang dialami oleh para guru untuk mengaplikasikan inovasi di sekolah. Seramai 63 orang guru bahasa Melayu dari lapan buah kolej vokasional telah dipilih sebagai responden dalam kajian ini. Data dianalisis menggunakan perisian Winsteps 3.69.1.11 dengan pendekatan Model Pengukuran Rasch. Hasil analisis menunjukkan bahawa guru�guru bahasa Melayu memahami kepentingan inovasi dalam pengajaran dan pembelajaran. Hasil kajian juga menunjukkan guru-guru perempuan lebih banyak menerapkan unsur inovasi dalam pengajaran berbanding guru lelaki. Walaupun begitu, aspek pengalaman tidak menunjukkan perbezaan dari segi pengamalan inovasi sama ada guru baru ataupun guru yang sudah berpengalaman. Pengkaji juga mengenal pasti beberapa kekangan yang dialami oleh guru-guru untuk mengamalkan inovasi ini. Sebagai langkah untuk menangani masalah berkenaan, beberapa cadangan telah dikemukakan oleh pengkaji bagi memastikan guru-guru dapat merealisasikan proses pengajaran berkesan dengan penerapan inovasi mengikut model pendekatan konstruktif. Pengkaji berharap, kajian ini dapat dijadikan sebagai satu panduan kepada pelaksana kurikulum bagi memastikan budaya inovasi sentiasa menjadi amalan dalam kalangan guru demi mengangkat profesionalisme guru di Malaysia

    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
