Embodiment 1

[0024] The embodiment of the present invention provides a method for intercepting junk information, see figure 1 , the method includes:

[0025] Step 101: receiving information to be intercepted;

[0026] Step 102: Convert the English letters and numbers in the non-preset format in the information to be intercepted to the English letters and numbers in the preset format, the English letters in the preset format are single-byte lowercase English letters, and the preset format The numeric characters in are single-byte Arabic numerals;

[0027] Step 103: determining the converted English letters and numbers in the information to be intercepted as the characteristic fingerprint of the information to be intercepted;

[0028] Step 104: If there is a feature fingerprint of the information to be intercepted in the stored sample feature fingerprint database, determine the information to be intercepted as spam information and intercept the spam information.

[0029] Among them, the n...

Embodiment 2

[0046] The embodiment of the present invention provides a method for intercepting junk information, see figure 2 , the method includes:

[0047] Step 201: the business system receives the information to be intercepted, and sends the information to be intercepted to the information interception system;

[0048] Specifically, the business system receives the information to be intercepted, and sends the information to be intercepted to the information interception system through the interception interface.

[0049] Among them, the information to be intercepted sent by the business system to the information interception system is uniformly encoded, for example, the information to be intercepted is uniformly encoded in GBK.

[0050] Step 202: The information interception system receives the information to be intercepted, and obtains the English letters and numbers in the information to be intercepted that are not in the preset format;

[0051]Specifically, the information interc...

Embodiment 3

[0077] see image 3 , the embodiment of the present invention provides a device for intercepting spam, the device includes:

[0078] A receiving module 301, configured to receive information to be intercepted;

[0079] The conversion module 302 is used to convert non-preset format English letters and numeric characters in the information to be intercepted into preset format English letters and numeric characters, and the preset format English letters are single-byte lowercase English letters, Numeric characters in the preset format are single-byte Arabic numeral characters;

[0080] The first determining module 303 is used to determine the English letters and numeric characters in the converted information to be intercepted as the characteristic fingerprint of the information to be intercepted;

[0081] The interception module 304 is configured to determine the information to be intercepted as spam and intercept the spam if there is a feature fingerprint of the information t...

Abstract

Systems and methods are provided for intercepting spam messages. For example, a message including one or more first characters is received, the one or more first characters not being associated with predetermined formats; the one or more first characters are converted to one or more second characters associated with the predetermined formats; the one or more second characters are determined as a feature fingerprint of message; and in response to the feature fingerprint of the message being included in a database of sample feature fingerprints, the message is determined as a spam message and the message is intercepted.

Description

technical field [0001] The invention relates to the field of Internet communication, in particular to a method and device for intercepting garbage information. Background technique [0002] With the rapid development of Internet communication technology, various types of spam appear in our lives, such as fraudulent information and illegal advertisements, and many users are deceived because of this type of spam, so blocking this type of spam is the key It is imperative to avoid users being scammed. [0003] At present, the specific method of intercepting spam information is as follows: technicians input spam information samples into the information interception system. The second prize, the prize is a Samsung notebook Q40 + 48,000 yuan bonus, please log in to www.cctv3yx.cn to get it, the verification code is: [1006]. Customer service: 400-6162-066". The information interception system extracts the sample features of the spam sample, including "very 6+1", "lucky audience", ...
