Investigation and prototype design of collaborative virtual learning environments

Virtual learning environments (VLEs) are online learning systems that are used to enhance a student's learning experience by providing a set of teaching, learning and communication tools. The current VLEs, however, are not fully utilised or exploited to support effective collaborative learning. This paper investigates how to build effective online collaborative virtual learning environments, by exploring the requirements of VLEs from personal users. A prototype is then created to show how the designs of current VLEs can be improved to provide the essential functionalities and ease of use. © 2012 IEEE

Critical challenges in access management schemes for smartphones: an appraisal

A growing trend exerted by current users in accessing sensitive data and performing critical data exchanges predominantly highlights the proliferation usage of mobile phone devices by users for accessibility. There exists a demand for a security solution capable of thwarting the existing threats while offering extended support, at the same time conserving user adaptability. In this research, an intensive survey has been conducted in which various security solutions based on biometric and non-biometric access management schemes have been contemplated. A lack of absolute or standard access control management scheme capable of delivering a secure and feasible solution on mobile phones persists. Each of the works offered by researchers has been single-handedly evaluated. Finally, loopholes and open challenges were deduced from the study conducted
