Abstract

The invention belongs to the technical field of website identification and locking, and provides an illegal website identification and locking method, which comprises the following steps of S101, monitoring and collecting keywords, and establishing a training sample according to a neural network algorithm; S102, extracting feature words; S103, performing text recognition on the keywords in a be-identified website; and S104, calculating the probability that the to-be-identified website belongs to each type according to the matching probability and the similarity. According to the illegal website identification and locking method provided by the invention, the target locking accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of website identification and locking, in particular to an illegal website identification and locking method and system. Background technique [0002] With the rapid development of the Internet, the openness of the website itself and the ubiquity of electronic payment have made the security of the website increasingly prominent. The activities of illegally engaging in various financial transactions through various website platforms have increased, which has brought greater financial and social risks. Hidden dangers, economic crimes involved are increasing day by day. The nature of illegal transactions on websites is diverse, and the currently discovered illegal transactions on the Internet are mainly concentrated in illegal online fundraising and virtual currency trading websites. [0003] These illegal Internet and mobile Internet software often have a legal form and appearance, and are highly conf...
