Abstract-Digital information has become a social infrastructure and with the expansion of the Internet, network infrastructure has become an indispensable part of social life and industrial activity for mankind. For various reasons, however, today's networks are vulnerable to numerous risks, such as information leakage, privacy infringement and data corruption. Through this research, the authors tried to establish an in-depth understanding of the importance of anonymous communication in social networking which is mostly used by ordinary and non-technical people. It demonstrates how the commonly used non-anonymous communication scheme in social networking can turn the Internet into a very dangerous platform because of its built-in nature making its users' identity easily traceable. After providing some introductory information on internet protocol (IP), internal working mechanism of social networking and concept of anonymity on the Internet, Facebook is used as a case study in demonstrating how various network tracing tools and gimmicks could be used to reveal identity of its users and victimize many innocent people. It then demonstrates working mechanism of various tools that can turn the Facebook social networking site into a safe and anonymous platform. The paper concludes by summarizing pros and cons of various anonymous communication techniques and highlighting its importance for social networking platforms.

This paper provides an overview of the technologies used in smart classrooms for distance education by classifying smart classrooms into four categories and discussing the type of  technologies used in their implementation. It gives an example of a successful implementation of distance education technology being used to link university campuses in Japan and the US, and  describes its underlying architecture and implementation technologies. It examines the methodologies being used to make distance learning an exciting experience and as effective as the traditional classroom type education. Furthermore, the paper shows how a similar architecture can be extended to a model where a single local class can simultaneously cater to the needs of multiple remote classrooms and presents a workable solution to some of the technical challenges that exits in multipoint, multiple classroom architecture. Finally, it shows how some of the inherent challenges of the system are being managed and identifies physical and practical limitations of a multiple classroom architecture for a successful remote lecturing environment.
