Context Aware Mobile Computing is an emerging strategic technology for enterprises. Context is highly dynamic in mobile environments; if fully utilized, it can bring substantial improvements in the productivity of an enterprise. Context aware mobile applications are fast becoming part of the mobile workforce of organizations. Enterprises are transformed into real time enterprises through mobile applications. Formation of new software engineering techniques requires the understanding of mobile as a pervasive device for computing, new ways of working and the usage of context in daily computing specifically in mobile environments. Developing context aware mobile applications of such nature require a rethinking of the software engineering techniques. The pervasive systems due to their properties and taxonomy require development of new requirement elicitation techniques. Since pervasive computing is a very broad subject the target of this research is to develop methods for requirements elicitation techniques for field force in various domains. This paper presents a method for using the requirement elicitation technique for the development of context aware mobile application for field force. [ABSTRACT FROM AUTHOR]

Until recently, all the security measures have addressed servers or networks while clients or network endpoints have missed the required security concerns relatively. Most of the mechanisms safeguarding endpoints (clients) are software based. Making endpoints survive in open and reasonably exposed environments-like internet-demand that client security should stand by a tried and true dependence and merely software based mechanisms are inadequate in providing the desired security level. Trusted Computing (TC) initiatives solve these security problems through operating environments, applications and secure hardware changes to the personal computer. Using secure hardware as a basis for trusted computing provides a level of relevance since hardware-based security is mooted difficult to compromise than conventional approaches. Therefore, TC provides a powerful set of features to implement applications such as secure auctions, integrity measurement, and biometric identification. In this paper, we present a detailed discussion of the different approaches towards a trusted computing platform; examine these approaches and provide a set of attack mechanisms enforced if trusted initiatives are not employed at user-level. The future directions along this line of research are also conferred. [ABSTRACT FROM AUTHOR]
