Comprehensive Filtering Method On A Terminal Of Multimedia Communication

With the continuous development of communication technology, the Internet and mobile communication becomes more and more popular. Therefore, study on comprehensive filtering methods on a terminal of multimedia communication come to be necessary.This article focuses on the characteristics of multimedia communications. In this paper, content-based information filtering techniques are analyzed, black and white list filtering method based on social engineering is designed, mechanism, and novel CAPTCHA contents of questions are designed.Content-based information filtering includes images and text filtering, this paper mainly do research on text-based content filtering, according to e-mail, SMS and other information content of different characteristics, this paper discusses different filtering methods.This paper designs using black and white list filtering method based on social engineering ideas, the user's information is considered. For communications the main initiator of the number of attribution, the two aspects of user behavior analysis, for the user itself to the number of attribution, the address book of attribution, the correspondence and other information for analysis. At last, the results of analysis to develop appropriate mechanisms for black and white lists.Different contents of CAPTCHA question are designed according to the hardware and bandwidth resources. For the conditions are limited, we designed a simple structured digital authentication information, through the decomposition of the matrix for the digital generation to achieve the verification of information decomposition; for better conditions to take a complex structure of image authentication information, using Photo zoning matrix decomposition and superposition to achieve the image content for the interference.Integrated approach will be designed basing on security level, communications scenarios such as demands for division of work to do with the three modules in order to achieve comprehensive filtering method on a terminal of multimedia communication.
