Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] figure 1 A schematic structural diagram of a domain name access control system based on user evaluation according to an embodiment of the present invention is given. The system includes a client and a server. Wherein, after receiving the domain name access request from the user, the client extracts the domain name from the domain name access request, and determines whether the domain name is in the local domain name collection. If it is in the local domain name collection, then send the domain name to DNS for normal domain name access; if it is not in the local domain name col...

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...
