Domain name access control method and system based on user evaluation

Abstract

The invention provides a domain name access control system based on user evaluation, which comprises a client side and a server. The client side extracts a domain name from a domain name access request of a user, and judges whether the domain name is in a local domain name set; if not, a composite score of the reliability of the domain name from other users is acquired from the server; and access to the domain name is controlled according to the composite score. The server is used for computing the composite score of the reliability of the domain name from multiple users. In the system, the client side judges the reliability of the domain name according to the local domain name set, and domain name evaluation can be submitted to the server only after the user accesses a webpage, so that evaluation from the user not using the webpage is avoided. In addition, the historical evaluation reliability and a time parameter are introduced for the user, so that an influence due to hostile evaluation is reduced; the accuracy of the evaluation is improved; and an influence due to a change of the domain name service quality on the stability of the system is inhibited effectively.

Description

technical field [0001] The invention belongs to the field of network security, and in particular relates to a method and a system for blocking malicious websites and garbage websites by referring to users' evaluations on domain names. Background technique [0002] With the continuous development of the network, the disseminated content is becoming more and more complicated, and users cannot judge whether the webpage is credible before opening the webpage. Some users unknowingly open some webpages that even contain a lot of pornographic, violent, deceptive information, etc., endangering users' physical and mental health and property safety. [0003] The domain name system is not only used to solve the problem of address correspondence, but also the basis of various applications and website construction. Domain name is a necessary condition for addressing access and the core of various Internet applications. Once the domain name is used maliciously, for example, criminals use...

Problems solved by technology

This method has the following problems: First, the method of text expression is ever-changing, and it is difficult for the machine to accurately identify it through the method of graphic and text recognition, so the accuracy of this method is not high; second, the indicators that can be judged by this method are limited, only characteristic comparison Strong violence, pornography, etc. are easier to judge, but indicators such as professionalism of web content are difficult to identify
