Communication between people is an important
factor for the development of the masses. From using animals
for carrying the message to using air as a medium,
communication has evolved into many forms. Sending letters
for communication is a passé as people can now talk through
web using video conferencing which is much more preferred
and convenient. The drawbacks of the traditional system of
VoIP which needs to install plugin or application to perform
the operation can be overcome with the help of open source
technology called Web-RTC. It allows users to directly
communicate with each other directly over browser without
the need of plugin. However, security of Web-RTC is main
concern. Web-RTC provides security mechanisms like
encryption, authentication andauthorization to the data being
exchanged over network. But any untrusted user can
interrupt the system and can directly start the
communication. This interruption can be prevented by
providing restriction on the untrusted user. The user who has
already registered can only start the communication with the
system and its users.
As shown in the fig.3.A, an anonymous user to the server
tries to call a user present in another system, which is
prohibited by the server as depicted in fig.3.B which
shows a message regarding the blocking of the intruder.
