Mobile Dua and Zikr for Hajj (MDZ4H)

In the last decade, the number of mobile phone users has increased dramatically. Nowadays, mobile phone has become part of people's life. Today's mobile phones provide not just voice call and messaging services, but plethora of other services. This research is about the utilization of mobile phone for dua and zikr for Hajj. The main aim of this research is to develop a mobile Dua and Zikr in order to help Hajj pilgrims to recite them while performing all the required rituals. At the moment, this research focuses on developing the application on Android platform. In developing the application, all the required Dua and Zikr have to be gathered, compiled and verified before the prototype could be developed using J2ME. The prototype consists of the text and audio files of the recited Dua and Zikr in Arabic as well as the translation in Malay. Finally the prototype has been evaluated by users and experts using two sets of questionnaires. It is hoped that the developed prototype would be able to help the pilgrims to easily and conveniently recite the Dua and Zikr towards achieving Hajj Mabrur

Towards a unified fraud management and digital forensic framework for mobile applications

Historically, progress in technology development has continually created new opportunities for criminal activities which, in turn, have triggered the need for the development of new security-sensitive systems. Organisations are now adopting mobile technologies for numerous applications to capitalise on the mobile revolution. They are now able to increase their operational efficiency as well as responsiveness and competitiveness and, most importantly, can now meet new, growing customers’ demands. However, although mobile technologies and applications present many new opportunities, they also present challenges. Threats to mobile phone applications are always on the rise and, therefore, compel organisations to invest money and time, among other technical controls, in an attempt to protect them from incurring losses. The computerisation of core activities (such as mobile banking in the banking industry, for example) has effectively exposed organisations to a host of complex fraud challenges that they have to deal with in addition to their core business of providing services to their end consumers. Fraudsters are able to use mobile devices to remotely access enterprise applications and subsequently perform fraudulent transactions. When this occurs, it is important to effectively investigate and manage the cause and findings, as well as to prevent any future similar attacks. Unfortunately, clients and consumers of these organisations are often ignorant of the risks to their assets and the consequences of the compromises that might occur. Organisations are therefore obliged, at least, to put in place measures that will not only minimise fraud but also be capable of detecting and preventing further similar incidents. The goal of this research was to develop a unified fraud management and digital forensic framework to improve the security of Information Technology (IT) processes and operations in organisations that make available mobile phone applications to their clients for business purposes. The research was motivated not only by the increasing reliance of organisations on mobile applications to service their customers but also by the fact that digital forensics and fraud management are often considered to be separate entities at an organisational level. This study proposes a unified approach to fraud management and digital forensic analysis to simultaneously manage and investigate fraud that occurs through the use of mobile phone applications. The unified Fraud Management and Digital Forensic (FMDF) framework is designed to (a) determine the suspicious degree of fraudulent transactions and (b) at the same time, to feed into a process that facilitates the investigation of incidents. A survey was conducted with subject matter experts in the banking environment. Data was generated through a participatory self-administered online questionnaire. Collected data was then presented, analysed and interpreted quantitatively and qualitatively. The study found that there was a general understanding of the common fraud management methodologies and approaches throughout the banking industry and the use thereof. However, while many of the respondents indicated that fraud detection was an integral part of their processes, they take a rather reactive approach when it comes to fraud management and digital forensics. Part of the reason for the reactive approach is that many investigations are conducted in silos, with no central knowledge repository where previous cases can be retrieved for comparative purposes. Therefore, confidentiality, integrity and availability of data are critical for continued business operations. To mitigate the pending risks, the study proposed a new way of thinking that combines both components of fraud management and digital forensics for an optimised approach to managing security in mobile applications. The research concluded that the unified FMDF approach was considered to be helpful and valuable to professionals who participated in the survey. Although the case study focused on the banking industry, the study appears to be instrumental in informing other types of organisations that make available the use of mobile applications for their clients in fraud risk awareness and risk management in general.ComputingM.

Prijedlog ontološki utemeljenog metodološkog okvira za razvoj više-platformskih mobilnih aplikacija

Software development teams are faced with the lack of interoperability during the development of mobile applications for two or more target platforms. The development for second and every other platform means a new project with a need to repeat almost all the phases defined by the chosen methodology but with a narrow possibility of reuse of the already defined artifacts. The existing efforts of professional and scientific community to solve this problem have a similar approach (code once, run everywhere) with similar advantages and drawbacks. Thus, this dissertation aims to propose a different solution and is concerned with: (1) analyzing the methodologies suitable for mobile applications development, (2) observing the implementation of prototype application in order to define artifacts that are created during the development process for two target platforms, (3) semantic description of artifacts and their meaning, and (4) defining unique ontological definition as a base for methodological interoperability. The results of a systematic literature review performed on 6761 primary studies, show that current state-of-the-art literature brings only 22 development methodologies and 7 development approaches which can be identified as eligible for multi-platform mobile applications development. Among these, Mobile-D methodology accompanied with Test Driven Development was chosen and used in the observed development processes for Android and Windows Phone platforms. Total of 71 artifacts were identified and the artifacts reusability level when developing for second target platform was 66.00%. In the last research phase, the artifacts for both platforms were semantically described into a single ontological description comprising 213 classes, 14 object properties and 2213 axioms defined in ALCRIF DL expression sub-language. Having this ontology proved as correct and valid, flexible, reusable and extensible we created the basis for development of an information system to guide the development teams in a more efficient and interoperable process of multiplatform mobile applications development.Razvojni timovi susreću se s problemom neinteroperabilnosti prilikom razvoja aplikacija za dvije ili više mobilnih platformi. Razvoj aplikacije za drugu i svaku sljedeću platformu znači novi projekt u kojem je potrebno ponovno provesti većinu faza definiranih odabranom metodikom razvoja, pri čemu se kreirani artefakti teško ili uopće ponovno ne koriste. Napori profesionalne i znanstvene zajednice za rješenjem ovog problema imaju sličan pristup (kodiraj jednom, koristi svugdje), slične prednosti, ali i zajedničke nedostatke. Stoga ova disertacija navedenom problemu pristupa na nov način i bavi se: (1) analiziranjem metodika pogodnih za razvoj mobilnih aplikacija, (2) promatranjem razvoja prototipne aplikacije u svrhu definiranja artefakata koji nastaju pri razvoju mobilne aplikacije za dvije ciljane platforme, (3) semantičkim opisivanjem definiranih artefakata i njihovih značenja, te (4) definiranjem jedinstvene ontološke definicije kao osnove za metodološku interoperabilnost. Rezultati sustavnog pregleda literature provedenog nad 6761 radom pokazali su da se trenutno u literaturi spominju 22 metodike i 7 pristupa koji su pogodni za razvoj više-platformskih mobilnih aplikacija. Između identificiranih metodika odabrani su Mobile-D metodika i pristup razvoju vođen testiranjem, koji su korišteni pri implementaciji prototipnog rješenja za Android i Windows Phone platformu. Ukupno je identificiran 71 artefakt pri čemu je ponovna iskoristivost artefakata pri razvoju za drugu platformu bila 66.00%. U posljednjoj su fazi istraživanja artefakti semantički opisani u zajedničku ontološku definiciju koja u konačnici sadrži 213 klasa, 14 objektnih svojstava i 2213 aksioma definiranih pomodu ALCRIF-DL jezika izraza. U radu je dokazano da je ontologija valjana, fleksibilna, ponovno iskoristiva i nadogradiva, čime je kreirana osnova za razvoj informacijskog sustava koji bi vodio razvojne timove u efikasnijem i bolje interoperabilnom procesu razvoja više-platformskih mobilnih aplikacija
