Disclosed is a method for blocking SMS spam messages in an SMS server or a mobile terminal. If the server receives an SMS message to be transmitted to a subscriber from a base station, it is determined if a spam blocking option is set. If the spam blocking option is set, a spam-blocking database is accessed to search for a phone number corresponding to the received message, so as to check whether the number is registered in the database. If the SMS message phone number is registered in the spam-blocking database, the procedure is ended without SMS message-processing for the message, so that spam messages are blocked from being transferred to the subscriber. If the terminal receives an SMS message, a spam-blocking database in the mobile terminal is accessed to determine if the received message is an SMS spam message. If the received message is an SMS spam message, the terminal is controlled not to notify receipt of the message.

The invention provides a Naive Bayesian classification based mobile phone spam short message filtering method and system. The system comprises a message intercepting module, a cache, a blacklist filtering module, a keyword filtering module and an intelligent Naive Bayesian classification filtering module. The message intercepting module is used for intercepting newly received short messages; the blacklist filtering module is used for filtering the new short messages according to a preset blacklist; the keyword filtering module is used for filtering the new short messages on the basis of preset keyword pairs; the intelligent Naive Bayesian classification filtering module is used for calculating probability that whether the new short messages are spam short messages or not by adopting a Naive Bayesian algorithm on the basis of a pre-trained feature word bank, and judging the new short messages as the spam short messages if the probability ratio exceeds a preset threshold, and as normal short messages otherwise. By the Naive Bayesian classification based mobile phone spam short message filtering method and system, through combination of the blacklist, the keywords, Naive Bayesian classification technology and Chinese word segmentation technology, the short messages are judged whether to be the spam short messages or not intelligently, so that the spam short messages are filtered.

A method and apparatus for implementing short message service (SMS) SPAM filtering is provided. The embodiments described herein integrate policy management into spam message filtering rules to enhance an SMS anti-spam mechanism.

A method for filtering spam directed at mobile phones in a short message system (SMS). A short message includes message content, and both a mobile phone number and a first authentication code of a destination mobile phone. A second authentication code of the destination mobile phone is stored in a memory. The short message is received and the first authentication code and the second authentication code are extracted from the short message and the memory, respectively. If it is ascertained that the extracted first authentication code does not match the extracted second authentication code, then the short message is determined to be SMS spam and is prevented from being subsequently received by the destination mobile phone. Otherwise the short message is determined to not be SMS spam and is not prevented from being subsequently received by the destination mobile phone. An authentication apparatus within the SMS performs the method.

The invention belongs to the technical field of information, and provides a method and device for recognizing a junk short message. The method comprises the steps that participial processing is carried out on a received short message to obtain N participial phrases, and N is an integer larger than one; the probability index that the short message is a junk short message is calculated according to the matching result of the participial phrases of the short message in a preset junk short message lexicon; when the probability index of the short message is larger than a preset threshold value, the short message is recognized as the junk short message. According to the method and device for recognizing the junk short message, participial processing is carried out on the new short message received by a terminal, searching and matching are carried out on the participial phrases obtained through processing in the preset junk short message lexicon, whether the received new short message is the junk short message or not is recognized according to the searching and matching result, therefore, the junk short message is automatically and intelligently recognized, and can be recognized without manual operation, and resource consumption to the terminal is lowered.

The invention discloses a keywords and frequency based method for identifying spam message sources. The method comprises the following steps: setting a keyword message frequency threshold which is the maximum threshold value violating the same keyword in a period, and blocking messages of a calling source in accordance to the keyword when the number of messages transmitted by the calling source violating the same keyword exceeds the maximum threshold value of the keyword message frequency threshold; and setting a blacklist threshold, namely setting the maximum threshold value which is the number of different keywords of the calling source exceeding the keyword message frequency threshold, determining the calling source to be a spam message source when the number of the calling source violating different keywords exceeds the maximum threshold value, and blocking all messages of the calling source. The method can effectively block spam messages by adopting a mode of combining keywords with frequency and listing sources violating a plurality of keywords simultaneously in the blacklist according to the sending characteristics of spam messages.
