The design of instant messaging system based on web

Abstract

With the rapid development of Internet, the use of network is becoming more and more widespread, and the distance is no longer a communication barrier between people. In order to solve the problem that the user needs to install program to the client and considers the differences of equipments & operating systems, this paper proposes a solution of IMSW (Instant Messaging System based on Web). It introduces the system architecture of IMSW, illustrates the function of the system, and describes the realization of three key technologies (such as Bootstrap responsive design, MD5 +salt encryption algorithm and video call) in detail. The system runs well, and it has a certain guiding significance for the project development of Instant Messaging.
