Method and device for detecting re-orientation of page in search engine

Abstract

An embodiment of the invention provides a method and a device for detecting the re-orientation of page in the search engine. Firstly the original page is analyzed for establishing a document object model DOM tree which is stored with each scripting language node content of the original page. Then each scripting language node in the DOM tree is traversed. If the node which quotes the outer dynamic scripting language exists, the outer dynamic scripting language is executed and the DOM tree is updated. Then whether one element selected from the current page address property, the time-delay execution function, the page loading initializing function, the meta-information property and the new window opening function is generated with re-orientation is determined sequentially according to the updated DOM tree. If the re-orientation exists, the re-orientation of the page is determined to exist. Through the application of the technical solution, the detecting to the re-orientation of the page can be detected based on the prior static page analysis thereby increasing the safety degree and the efficiency of the searching and improving the using experience of the subscriber.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for detecting page redirection in a search engine. Background technique [0002] At present, in the application process of web search engines, there is generally a problem of redirection spam. The so-called redirection spam refers to the search engine building an index by providing false content, but when the user actually visits the index to provide page, the page will automatically redirect to another page. For example: when a user visits page A provided by the index, the page is immediately redirected to page B, and this page B is likely to be a problematic page, which brings security risks to the user's search process. [0003] In the prior art, search engines generally create indexes based on the analysis of static pages, so that users can quickly find the information they need when searching for keywords; and for the problem of page redirection, sea...

AI Technical Summary

Problems solved by technology

Because the search engine in the prior art scheme is based on the detection mechanism of static page analysis, it is impossible to detect the page redirection achieved by dynamic scripts, so that a lot of redirection garbage is generated, so that the redirection garbage pages are listed in the search results. Shown in , the security risks brought to the user's search process have affected the user's experience
