Dynamic Advertisement Analysis Method And Replay Technology Research

The development of the Internet has led to the development of advertising.Online advertising is the most popular advertisement nowadays,it becomes one of the most important business models of the Internet.But online advertising has some negative effects.Some advertisements not only steal user's privacy information,but also secretly install malicious software to user's computers.Advertisements for criminal activities are called malicious ads,malicious advertisements are rampant,and any role in the advertising process could become a hacker,including publishers,ad networks and publishers.Most malicious advertisements only discover their malicious behavior after attacking the user,and it is difficult to reproduce the advertisement after the malicious attack,which is also bad for the analysis of its malicious behavior.In view of the above problems,the research content of this paper is:(1)proposes a dynamic advertising analysis method;(2)realizes the replay of advertisement.The main work of this paper is as follows:(1)A new analysis method of advertisement is proposed in this thesis,which can organize the ad paths on the web page and form many forks tree,making a comparasion analysis to the many forks tree obtained from multiple access to a web page.By using this method,the domain name information can be obtained and the dynamic behavior of advertisement can be analyzed conveniently;(2)Verifies the change characteristics of advertisement,analyzes the reason of the dynamic change of advertisement,hence makes use of the file cached in local in the process of instrument and modifies the rules of agent to realize the replay of advertisement.The experimental results show that:(1)The relationship between the domain name in advertising call path is stable,and before advertising displaying,there will be a relevant documents to collect user information for accurately targeted advertising.The advertisement analysis method proposed can effectively locate the change of advertisement;(2)After the advertisement reproduced,there is no new document to be cached locally and web page displaying the contents of advertisements is same with the advertising cached in the local,it also can recreate the invocation path of advertising,which has great significance on the malicious ads where link was failure after malicious attacks;(3)The access time of the webpage is within acceptable range after instrumenting.
