Unhealthy Website Filtering System For Intelligent Terminal Based On Cloud Computing

With the rapid development of information technology and intelligent terminals,it is also more and more convenient for the smart terminals to connect to the Internet,and the user's entertainment time gradually shifts from personal computers to smart terminals.However,the Internet is a rich and free space.It is easy for malicious people to make use of the bad information to release social influence.Therefore,some traditional software enterprises at home and abroad have developed products such as cell phone guards with bad website interception function for smart terminals.However,some of these products have not been combined with the current mainstream cloud computing,and some of these take the filtering method is easier to achieve,such as blacklist matching detection,which does not play to the advantages of cloud computing platform to handle large amounts of data.Thus research on how to combine the current major filtering technologies of adverse website with the mainstream cloud computing platforms to for m complementary advantages is certain significance.This paper is aimed to study on the bad website filtering technology based on cloud computing.The main work is to extract the features of the bad texts and bad pictures and the n classify them and finally classify the bad website according to the result of classification of them.In this paper,an improved KNN algorithm based on the Spark platform is used to classify the content information on the webpage.Finally,a comprehensive analysis of the types of the bad texts and the types of the bad images is performed by using the decision tree algorithm model,which finally determines the bad type of the bad websites.At the same time according to the pre-set threshold given the site's dangerous level.At last,a bad website filtering system based on cloud computing is designed,implemented and tested in this paper.Also,descriptions of general system design,client design,cloud server design,database design and the implementation of related functions based on Spark cloud computing platform are provided.The testing of each function of the prototype system shows that the design of cloud-based intelligent terminal bad website filtering system has the capability of meeting the needs and can play a role in the actual scene.
