Chinese counterfeit domain name detection method and Chinese counterfeit domain name detection system

Abstract

The invention discloses a Chinese counterfeit domain name detection method and a Chinese counterfeit domain name detection system, which are suitable for detecting Chinese counterfeit domain names formed by using similar Chinese characters. The Chinese counterfeit domain name detection system comprises a domain name preprocessing module, which is used for counting length and a total stroke number of every input domain name; a target domain name filtering module, which is used to compare the lengths and the total stroke numbers of the to-be-detected domain names and that of the target domain names, and is used to filter target domain names of a possibly-imitated target domain name set; a domain name disassembling module, which is used to disassemble the to-be-detected domain names and the filtered target domain names correspondingly into single Chinese characters; a single character similarity calculation module, which is used to convert the Chinese characters into character strings of stroke orders, and is used to calculate single character similarity based on character string editing distance; a domain name similarity calculation module, which is used to calculate the similarity of the integral domain name based on the single character similarity; and a counterfeit domain name decision module, which is used to determine and output the most possibly-imitated target domain name based on the domain name similarity. By adopting the above mentioned method and the above mentioned system, the Chinese counterfeit domain names formed by using the similar Chinese characters are effectively identified, and a wide application prospect is provided in a network safety field.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method and system for detecting counterfeit Chinese domain names. Background technique [0002] In recent years, with the development of online finance and e-commerce, phishing websites have grown explosively, seriously threatening the security of public property and information. Phishing is a common technique in phishing. Attackers deceive users by registering a domain name similar to the target domain name, and then steal users' sensitive personal information. [0003] The traditional domain name system can only use 63 ASCII characters ("a-z", "A-Z", "0-9", "-"). With the rapid development of the Internet in non-English-speaking countries, internationalized domain names are rising day by day, and the character set that domain names can use has expanded to hundreds of language characters. Chinese domain names are an important part of internationalized do...

Problems solved by technology

However, the current counterfeit domain name detection method is mainly aimed at English domain names, and it is difficult to apply to Chinese domain names with complex and changeable fonts.
