M-learning or mobile learning is defined as learning through mobile apps, social interactions and online educational hubs via Internet or network using personal mobile devices such as tablets and smart phones. However, in such open environment examination security is most challenging task as students can exchange mobile devices or also can exchange information through network during examination. This paper aims to design secure examination management system for m- learning and provide appropriate mechanism for anti- impersonation to ensure examination security. The users are authenticated through OTP. To prevent students from exchanging mobile devices during examination, system re-authenticates students automatically through face recognition at random time without interrupting the test. The system also provides external click management i.e. prevent students from accessing online sites and already downloaded files during examination.

The evolution of modern mobile devices towards novel Radio Frequency (RF) capabilities, such as Near Field Communication, leads to a potential for delivering innovative mobile services, which is still partially unexplored. Mobile proximity payment systems are going to enhance the daily shopping experience, but the access to payment security resources of a mobile device (e.g. the “Secure Element”) by third party applications is still blocked by smartphone and Operating System manufacturers. In this paper, the IDA-Pay system is presented, an innovative and secure NFC micro-payment system based on Peer-to-Peer NFC operating mode for Android mobile phones. It allows to deliver mobile-to-POS micro-payment services, bypassing the need for special hardware. A validation scenario and a system evaluation are also reported to demonstrate the system effectiveness and performance.

Learning Management

På Bioanalytikeruddannelsen på Professionshøjskolen Metropol har vi på ti-ugers modulet ”Molekylærbiologiske og genetiske analyser”, udviklet en digital portfolio som didaktisk redskab. Portfolien er blevet afprøvet på fire forløb, og har været med til at skabe større engagement blandt de studerende og øget transfer mellem teori og praksis. Artiklen tager afsæt i erfaringerne fra udvikling, anvendelse og evaluering af den digitale portfolio og peer to peer feedback. Portfolien er digital og tilknyttet Metropols Learning Management System. De studerende uploader individuelt ugentligt deres arbejde tilknyttet ugens fokusområde. En gang om ugen giver de studerende hinanden peerfeedback på ugens arbejde. Anvendelsen af portfolien har øget de studerendes kompetencer til at give og anvende peerfeedback. De studerende angiver, at de opnår en høj grad af læring i forbindelse med arbejdet med portfolien, bl.a. fordi de oplever, at det forpligter, at de skal dele portfolien og feedbacken med en medstuderende. Desuden oplever vi som undervisere, at de studerendes faglige niveau er blevet væsentligt forøget blandt de studerende, der aktivt har benyttet portfolien i samspil med feedback.

Mobile adhoc networks (MANETs) have drawn attention to multitudinous consideration because of the univerality of mobile devices as well as the developments in wireless era. MANET is a peer-to-peer multi hop cellular wireless era community which does not have both difficult and speedy infrastructure and a relevant server. Every vertex of a MANET performs like a router and communicates with every unique. There exist numerous information duplication strategies which were presented to reduce the execution squalor. All are concluded that everyone cell vertices cooperate completely from the perspective of sharing their memory vicinity. But, via a few methods few vertices might additionally behave selfishly and determine simplest to cooperate in part or never with different vertices. The selfish vertices ought to then lessen the overall information approachability within the network. From this work, we try to take a look at the influence of selfish vertices in a mobile ad hoc community in terms of reproduction issuance i.e Selfish nodes are dealt with in replica allocation.

The evolution in mobile messaging and mobile devices has made it possible to provide multimedia rich messaging capabilities to personal digital assistants (PDAs). The need for this arises simply because mobile service providers want to provide an enhanced messaging experience to the user. It also opens up new avenues for business, such as a shopping mall scenario. This chapter discusses the development of a multimedia messaging client for a PDA and a kiosk providing multimedia messages composition, search, share, and sending capabilities. This chapter also discusses the various messaging technologies, enabling wireless technologies, and the peer-to-peer model. The peer-to-peer technology used was Jxta, an XML-based and language agnostic peer-to-peer platform specification from Sun Microsystems. The peers (PDA client and the kiosk) were implemented using the application programming interfaces provided by the Personal Java reference implementation and the Jxta platform’s Personal Java port.
