Research Of Text Flow Recognition System Under The Integration Of Telecommunications Networks, Cable TV Networks And The Internet

Under the promotion of government, the development of trip le-play is getting faster,and net environment is getting more open. All of these require a much more higher security.The internet contents monitor has always been talking about around government andenterprises. Construct HUSTRIM (Huazhong University of Science and Techno logyTelevision and Radio Information Management) monitoring frame to monitor the contentswhich include text, video, audio and image. Compared with the video, audio and image, texttakes the advantage of smaller data volume and convenient production. From all of theseadvantages, means less difficulty of computer recognition and wide usages, relatively.Just because of the convenient production of text information, without a camera ormicrophone, text characters generated from everywhere. It shows the text informationregulatory focus lies in real-time environment. And this means the real-time transmissionof the text stream supervision filter against the background of the network integration hasits necessity and importance. Considering the experiences of the mode of firewalltechnology, rise an idea of a likewise supervision mode which inspects data packets to digtext information against the network transmission stage.Applying the deep packet inspection, multiple pattern matching algorithm and alleffective strategies into such design of text flow real-time monitoring, expands the targetsof current firewall from the original attacking against physical devices to mental attackingof harmful text which is against the users of the net. With the strategy of distribution ofdetecting nodes into the network, greatly reduce the work load of the monitoringdepartment, also expands the oversight of supervision and improves efficiency. There isno doubt such real-time supervision mode is also a kind of reference to other contentmonitor. In the foreseeable future, under the period of real-time transition as long as agood solution of computer resources and efficient algorithm exists, this mode has tobecome the current supervision mode.
