Embodiment Construction

[0045] figure 1 Schematic diagram of the scene of the spam identification method provided by the present invention, such as figure 1 As shown in , the mail is sent by the server in the foreign domain or the server in the local domain, and then received by the mail server. Usually, the sender will send a large amount of spam on the external domain server or the local domain server. If these spam emails are only sent through a single IP address, this IP address is easy to be found and then blocked. Therefore, senders use a large number of IP addresses to send spam. In this embodiment, the feature that the mail server can receive a large number of mails with the same content sent from different IP addresses can be used to identify these mails, so as to identify whether the mails are spam or normal mails.

Abstract

The invention provides a spam identification method and device. The identification method of the spam includes: receiving the mail and analyzing the mail to obtain the IP address and the content of the mail, wherein the content of the mail includes a subject, a text and an attachment; calculating the content of the mail through a preset verification algorithm, Get the verification code of the mail; judge whether the verification code of the mail exists in the spam sample, wherein, the verification code corresponding to different spam is stored in the spam sample; if the verification code of the mail exists in the spam sample , the email is identified as spam. The method and device provided by the invention can identify mails based on the behavior characteristics of spam, so as to improve the recognition rate of spam.

Description

technical field [0001] The invention relates to spam identification technology, in particular to a spam identification method and device. Background technique [0002] With the wide popularization of the Internet, email has become one of the commonly used communication tools, but users often receive various spam emails, which seriously affects the user's checking and processing of normal emails. Therefore, identifying spam is becoming more and more important. [0003] At present, the Bayesian recognition technology based on probability statistics is a commonly used spam recognition technology. The number of email samples and spam samples. [0004] However, the Bayesian recognition technology based on probability and statistics is not effective for the recognition of spam information (such as pictures, etc.) that is not suitable for word segmentation, and there is an urgent need for a spam recognition technology with higher recognition accuracy. Contents of the invention ...
