Embodiment Construction

[0029] The phishing webpage detection method based on image processing is as follows: calculate the similarity between suspicious phishing webpages and each protected webpage one by one, and judge suspicious webpages whose similarity between suspicious webpages and protected webpages is less than a preset value is a phishing page targeting the protected page;

[0030] The above-mentioned phishing is a means of inducing users to input sensitive information and illegally obtaining such sensitive information by imitating relevant pages of online finance or other network service providers;

[0031] The above-mentioned suspicious phishing web pages are: web pages pointed to by link addresses detected from suspicious emails, or phishing web pages reported by users;

[0032] The above-mentioned protected webpages are: the target webpage forged by phishing;

[0033] The above method for calculating the similarity of web pages is as follows:

[0034] Step 1, convert the web page to a...

Abstract

The invention relates to the field of image information processing and network security, in particular to a method for detecting a phishing webpage based on image segmentation. The invention calculates the similarity between the suspicious phishing webpage and each protected webpage one by one, and determines that the suspicious webpage is the phishing webpage as for the protected webpage, when the similarity thereof with the protected webpage is smaller than the preset value. The invention is characterized in that the webpage image visited by users can be directly analyzed, with high reliability and difficulty to be cheated by webpage design technique; by segmenting a webpage picture, partial matching can be realized, preventing network phishing caused by partial similarity; the matching method that pays equal attention on sub-image properties and relationship meets visual psychology better and makes the matching results more accurate. According to the data obtained by experiments, the invention has the advantage of high detection precision of webpage image.

Description

technical field [0001] The invention relates to the fields of image information processing and network security, relates to an anti-phishing method, in particular to a method for detecting phishing webpages based on image processing. Background technique [0002] Phishing (Web Phishing) is a kind of online identity impersonation, which uses social engineering (that is, deception) and technical means (including malicious code, phishing emails, monitoring software, etc.) to steal personal identity information or account numbers of network users, Passwords, credit card numbers, etc. Phishing has now become a great threat to user information security, and has caused huge economic losses to users (according to authoritative organizations, the loss caused by phishing in the United States in 2007 reached 2.8 billion U.S. dollars); It has seriously hindered the development of electronic finance such as online banking and online payment in my country. [0003] At present, the common...
