Description
Technical field
The present invention relates to the note treatment technology of the communications field, the system of particularly a kind of monitoring spam and process, device and method.
Background technology
Along with the development of the communication technology, communication network operator provides diversified applied business in a communication network, and one of them is exactly note.Along with using the user of note to get more and more, illegal refuse messages also gets more and more.How the network side of communication network monitors these refuse messages and deletes, and also becomes one of problem that communication network side will solve.
At present, the mode that communication network side monitoring rubbish note also processes, mainly through keyword filter type, flow control mode and blacklist mode these three kinds, specifically describes as follows:
Keyword filter type: pre-set keyword in communication network side, the keyword of setting, receiving before note do not forward, mates with short message content, if the match is successful by communication network side, then determine that this note is refuse messages, then this SMS interception is deleted; If do not mated, be then transmitted to receiving terminal;
Flow control mode: the note quantity thresholding sent in setting-up time for a terminal is set in communication network side, as 1 hour 200, the note quantity that same transmitting terminal sends in setting-up time is monitored in communication network side, if when exceeding the note quantity thresholding sent in setting-up time, then tackle this transmitting terminal in the note of follow-up transmission and delete; If do not exceed the note quantity thresholding sent in setting-up time, then the note of this transmitting terminal is transmitted to receiving terminal;
Blacklist mode: blacklist is set in communication network side, communication network side is receiving before note do not forward, determine to send the transmitting terminal of this note whether in set blacklist, if so, is then deleted by this SMS interception; If not, be then transmitted to receiving terminal.
In technique scheme, employing keyword filter type carries out monitoring with when processing to refuse messages, and monitoring and leakage are monitored higher by mistake.This is because, carry out in matching process to the keyword of short message content and setting, mate based on Chinese key, such as: the keyword of setting is " invoice " etc., when refuse messages can evade set keyword when sending, adopt obfuscation and the splicingization word such as " sending out * to waft ", " sending out one to waft " (middle " one " for Chinese), " invalidated ticket " or " sending out boomerang ", namely add non-Chinese character at refuse messages, and utilize the means such as Chinese homonym and shape similar word to evade the keyword monitoring set by pass.The keyword that communication network side is arranged cannot match the content of these refuse messages, but for receiving terminal, gets in touch with the context of these refuse messages, is readily appreciated that these refuse messages.
A full instance: the content of refuse messages is " our company opens various regular invalidated ticket in generation, intentionally R. S. V. P. Mr. Li 1391111111 ", at this moment adopts the keyword of " invoice " just cannot monitor this refuse messages.In addition, also have some to have the refuse messages of the content put upside down by keyword, such as " ticket is sent out ", cannot adopt keyword filter type to monitor, but for receiving terminal, from the context, be just readily appreciated that refuse messages content.Another full instance: the content of refuse messages is " machine is played regular ticket and sent out; have needs please contact Miss Zhang 1581223333 ", adopt the keyword of " invoice " just cannot monitor this refuse messages, but receiving terminal just can be readily appreciated that this refuse messages content.In order to overcome these problems, carry out in matching process to the keyword of short message content and setting, the phonetic arranged based on Chinese key conversion mates, although this can be avoided using homonym to be content refuse messages evade Keywords matching problem, but the refuse messages into content is put upside down for use homograph or keyword, but still can evade Keywords matching.
In technique scheme, the monitoring that the flow control mode adopted carries out refuse messages and process are property afterwards, the note quantity thresholding sent in setting-up time is exceeded when monitoring the note quantity that same transmitting terminal sends in setting-up time, and then tackle this transmitting terminal in the note of follow-up transmission and delete, a large amount of refuse messages that this transmitting terminal sends early stage are successfully transmitted to receiving terminal by communication network side.
In such scheme, the blacklist mode adopted carries out monitoring and the process of refuse messages, and the process setting up blacklist is veryer long, and mainly or in communication network side is undertaken by the artificial mode verified.
Communication network side is in order to more effectively monitor and process note, and usually above-mentioned three kinds of modes be combined, technical scheme when being combined mainly contains following several:
The first technical scheme: the note quantity thresholding that blacklist is set in communication network side simultaneously, send for a terminal in setting-up time and keyword.Communication network side is when receiving note, whether the transmitting terminal first determining to send this note, in blacklist, if so, is then tackled this note and deletes, if not, then monitor the note quantity that same transmitting terminal sends in setting-up time, if do not exceeded, just forward this note, if exceeded, the keyword of setting is mated with short message content, if the match is successful, then the transmitting terminal sending this note is arranged in blacklist; If do not mated, be then transmitted to receiving terminal;
The second technical scheme: communication network side arranges dynamic blacklist, namely by manual analysis and refuse messages report information, dynamically arrange blacklist, communication network side is receiving before note do not forward, determine to send the transmitting terminal of this note whether in set dynamic blacklist, if so, then this SMS interception is deleted; If not, be then transmitted to receiving terminal;
The third technical scheme: the note quantity thresholding that blacklist is set in communication network side simultaneously, send for a terminal in setting-up time and keyword.Communication network side is when receiving note, whether the transmitting terminal first determining to send this note, in blacklist, if so, is tackled this note and deletes, if not, monitor the note quantity that same transmitting terminal sends in setting-up time, if do not exceeded, just forward this note, if exceeded, the keyword of setting is mated with short message content, if the match is successful, tackles this note and delete this note; If do not mated, be transmitted to receiving terminal.
In above-mentioned association schemes monitoring with disposal of refuse note, for the first technical scheme: adopt the prerequisite that flow control mode filters as keyword, cause before execution keyword filters, the refuse messages of some issues, and when adopting keyword filter type, False Rate and misdetection rate are all higher; For the second technical scheme, the process of establishing of set blacklist is very long, is also treatment mechanism afterwards; For the third technical scheme, three kinds of modes are independently carried out, do not overcome three kinds of existing self-defects of mode.

In this embodiment, the basic keyword rule rule set by employing also comprises: deleted by the non-Chinese character in the short message content of this note before mating short message content.
In this embodiment, calculate the method flow of the doubtful value of refuse messages of coupling as shown in Figure 4, its concrete steps are:
Each keyword derivative in keyword derived sequence or derivatives order mate with the content of this note by step 401, communication network side, if the match is successful, record the keyword derivative that the match is successful or the doubtful value of refuse messages corresponding to derivatives and the short message content position that the match is successful, proceed to step 402; If do not had, the match is successful, then carry out the coupling of next keyword derivative or derivatives, proceeds to step 401 and continue to perform, until each keyword derivative in keyword derived sequence or derivatives were mated, proceed to step 403;
Step 402, communication network side continue the keyword derivative that the match is successful or derivatives to carry out the coupling behind the short message content position that the match is successful, determine whether that the match is successful, if not success, then carry out the coupling of next keyword derivative or derivatives, proceed to step 401 and continue to perform; If not, the then next short message content position that the match is successful of record, calculating refuse messages doubtful value is: the doubtful value of next refuse messages is divided by after the difference of the doubtful value of next refuse messages and the short message content position that the match is successful and next short message content position that the match is successful, with the doubtful value of refuse messages and as the doubtful value of refuse messages of this derivative or derivatives, continue to proceed to step 402 to mate, until all mated this short message content, carry out the coupling of next keyword derivative or derivatives, proceed to step 401 and perform;
The doubtful value of refuse messages of all each keyword derivatives of obtaining or derivatives is added by step 403, communication network side, obtains the doubtful value of refuse messages of final coupling.
In the present invention, set basic keyword rule judges one group of the refuse messages basic keyword combination be associated, as: rule 1: " generation opens "+" invoice "; Rule 2: " Falun Gong "; Rule 3: " gun "+" buying on behalf " etc.Set keyword derived sequence is in units of each keyword in every bar basic keyword rule, to form the word of each keyword for target, by these keywords according to homophonic, similar shape or/and the principles such as font fractionation carry out key derivation formation.Here, keyword carry out derivative after, it is a word that a keyword may derive, each keyword correspondence derived is provided with a doubtful value p of refuse messages (0 < p < 1), and p is preset according to the conventional degree of this keyword in Chinese character and the frequency that occurs in refuse messages by communication network side.Keyword " gun " in such as above-mentioned regular 3, after carrying out key derivation, derived sequence " rifle (0.3) ", " robbing (0.1) ", " choke (0.1) ", " wooden storehouse (0.5) ", " deep blue (0.1) " is formed with " rifle " word ..., form derived sequence " (0.2) ", " only (0.1) " and " skill (0.1) " with " propping up " word ....
In the present invention, refuse messages Suspected Degree P judges that whether note is the metric of refuse messages, it is more than or equal to 0, as being greater than the doubtful refuse messages thresholding T1 of setting, as 80%, then think refuse messages, as when being set as in certain limit and note through judgement after drop in scope time, as 50% < p < 80%, then think doubtful refuse messages, if be less than or equal to 50%, non-junk note can be thought.
Lift an object lesson and the doubtful value process of refuse messages calculating coupling is described.
Basic keyword rule: " gun "+" buying on behalf "
Keyword derived sequence: keyword " gun ": " rifle " derivative sequence { rifle (0.5), robs (0.1), choke (0.1), wooden storehouse (0.5), deep blue (0.1) }; " prop up " derivative sequence { (0.1), (0.1), skill (0.1) };
Keyword " is bought on behalf ": " generation " derivative sequence { in generation (0.1), band (0.1), cuts down (0.1), borrows (0.1), bag (0.1) }; " purchase " derivative sequence { purchase (0.1), ditch (0.1), hook (0.1), enough (0.1), shellfish hooks (0.5) }.
Communication network side joint receives the content short message content of note for " & is with & to prop up one by one in all kinds of wooden storehouse of shellfish hook one by one; have needs please contact Wang 1381199900 ", (remarks, in foregoing, " one " is Chinese character one, not English horizontal line character).Become after have passed through the deletion preliminary treatment of non-Chinese character: " band is purchased all kinds of wooden storehouse one by one and propped up one by one, has needs please contact Wang 1381199900 ".
According to matching algorithm, the matching result that keyword " is bought on behalf " is band (0.1), position 1, and shellfish hooks (0.5), position 6; So P=0+0.1+0.5/ (6-1)=0.2; The matching result of keyword " gun " is wooden storehouse (0.5), position 10, (0.1), and position 15, so P=0.2+0.5+0.1/5=0.72; Finally, the doubtful value of refuse messages of this note is 0.92, has exceeded set refuse messages Suspected Degree 80%, so be judged as refuse messages.
In the present invention, thered is provided keyword filter type can also be combined with provided flow control mode the monitoring carrying out refuse messages, certainly, also can before or after association schemes, blacklist filter type be adopted to monitor refuse messages further further.
Fig. 5 is the embodiment of the method flow chart of monitoring spam provided by the invention and process, and its concrete steps are:
After step 501, communication system network receive note, adopt the blacklist arranged to mate the transmitting terminal sending this note, if the match is successful, then determine that this note is refuse messages, delete and report result of determination; If not, then step 502 is performed;
Basic keyword rule rule set by step 502, communication network side adopt is mated short message content, determines whether that the match is successful, if so, proceeds to step 503; If not, step 504 is proceeded to;
This note as refuse messages, is deleted this refuse messages, and is reported court verdict by step 503, communication network side, is arranged in blacklist by the transmitting terminal sending this refuse messages;
Keyword derived sequence set by step 504, communication network side adopt mates this short message content and calculates the doubtful value of refuse messages of coupling, judge whether the doubtful value of refuse messages calculated is more than or equal to set refuse messages Suspected Degree, if so, step 503 is proceeded to; If not, then step 505 is proceeded to;
Step 505, communication network side judge the doubtful value of refuse messages that calculates whether in the scope of doubtful refuse messages Suspected Degree, if so, perform step 506; If not, this note is forwarded as non-junk note;
Step 506, this doubtful refuse messages of communication network side buffer memory, to the transmitting terminal monitoring sending this refuse messages, determine whether its transmission note amount exceedes the threshold value of setting in setting-up time, if so, performs step 507; If not, step 508 is performed;
In this step, suppose that setting-up time is 30 seconds, the note quantity that the transmitting terminal that statistics sends this doubtful refuse messages in 30 seconds sends, if exceed the threshold value of setting, then perform step 507; If not, step 508 is performed;
In this step, within the time period of monitoring, continue the refuse messages received as the terminal of transmitting terminal by sms center/short message network from this to carry out buffer memory;
Step 507, communication network side are deleted the refuse messages of institute buffer memory and are deleted the refuse messages of follow-up institute buffer memory, report result of determination, are arranged in blacklist by the transmitting terminal sending this doubtful refuse messages;
The doubtful refuse messages of institute's buffer memory is transmitted to receiving terminal by step 508, communications network network.
Lift an object lesson to illustrate: communication network side joint receives the note 5 that transmitting terminal sends, wherein one is judged as doubtful refuse messages, then by buffer memory, this is judged as the note of doubtful refuse messages in communication network side, and start setting timer, the time is 30 seconds.In 30 seconds, if continue to receive note that this transmitting terminal sends and be judged as doubtful refuse messages, just continue buffer memory, timer is to constantly by the time, the doubtful refuse messages number of this transmitting terminal transmission of statistics institute buffer memory, whether exceed the thresholding 3 of setting, if so, then judge that these doubtful refuse messages are as refuse messages, if not, then doubtful refuse messages is defined as non-junk note, carries out forward process.
In the present invention, adopt keyword filter type monitoring short message, often can not 100% to be confirmed whether as refuse messages.This is because refuse messages content is easy to change, the keyword in basic keyword rule will be mated completely, more difficult, for the semi-match situation obtained according to key derivation sequence, just need to determine whether, into doubtful refuse messages or refuse messages, to carry out different processing procedures according to its metric.Such as: basic keyword filtering rule is " invoice "+" generation opens "+" contact ", and short message content have matched " invoice "+" contact " wherein, then this note is located doubtful refuse messages.
More than lift preferred embodiment; the object, technical solutions and advantages of the present invention are further described; be understood that; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all, any amendment done, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
