Embodiment Construction

[0020] see figure 1 , which is a flow chart of the client-based phishing website detection method of the present invention. The client-based phishing website detection method comprises the following steps:

[0021] Step S11: the user logs in to the website.

[0022] Step S12: Send the URL logged in by the user to the server to query the security of the URL.

[0023] Wherein, the server is provided with a library of black and white URLs, which collects all black URLs and white URLs found so far. The black URLs are phishing URLs, and the white URLs are legal normal URLs. The URL logged in by the user is sent to the server for comparison with all URLs in the black and white URL database. If it matches a black URL, it is judged as a phishing website, prompting that customers are prohibited from accessing the URL; if it matches a white URL, it is judged as normal URL to allow the user to access. If the URL logged in by the user does not match any of the URLs in the black and wh...

Abstract

The invention relates to a client-based phishing website detecting method comprising the following steps: 1. sending a user login website to a service terminal to inquire the safety of the website, sending the user login website back to a client to be detected if the website is an unknown website; 2. extracting the website characteristics of the user login website from the client, comparing the website characteristics with the characteristic library of the user terminal to judge whether the user login website is a phishing website or not, if so, sending the user login website to the service terminal, and if not, permitting the access to the user login website; and 3. accumulating the people number accessing the website at the service terminal, wherein the service terminal judges the website as client misinformation and allows the access when the accumulated people number exceeds a threshold value. Compared with the prior art, the client-based phishing website detecting method provided by the invention is used for quickly looking for Hackers through the service terminal, and then quickly judging the unknown websites through the client and finally preventing wrong judgment through the service terminal. The client-based phishing website detecting method can be used for quickly and accurately detecting the phishing websites.
