Method and apparatus for intercepting junk mail

Abstract

The invention provides a method for intercepting junk e-mail and a device thereof. The method mainly comprises: text data of an e-mail, which needs to be filtered is acquired, and whether the text data includes a key word which is in a character string in a character string resource bank and is used for filtering the e-mail or not is judged; when the key word is included in the text data, whetherthe text data includes the character string in the character string resource bank corresponding to the key word or not is judged; according to the judgment result that whether the text data includes the character string in the character string resource bank corresponding to the key word or not and a pre-determined judgment strategy, whether the e-mail is the junk e-mail or not is determined, and the junk e-mail is intercepted. By adopting the invention, the text data of the e-mail is scanned according to the key word, after the key word is matched, the text data of the e-mail is scanned according to the character string corresponding to the key word, so that the scanning speed and efficiency are improved, and the e-mail can be filtered in real time when the character string library is larger.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for intercepting spam. Background technique [0002] In the field of e-mail, spam is becoming more and more rampant, which not only increases the processing time of normal mail users, but also wastes valuable resources of the mail system, thereby hindering the process of users obtaining useful information. Therefore, spam is a must. issues that need resolving. [0003] At present, string-based interception technology is commonly used in email systems to combat spam. This string-based interception technology needs to establish a string library in advance. The strings in the string library use existing words or words. The length of the string is relatively fixed. The string library needs to have a certain update period and scale, and the string size available for scanning in the string library often reaches millions. In practical applications, u...

Problems solved by technology

[0006] The above processing forms of full-text sequential scanning or regular expression matching use the complete strings in the string library to filter emails. When the size of the string library is relatively large, the efficiency is low, and it is impossible to filter the received emails in real time. , which seriously affects the user's use effect
