Fig. 3 and Fig. 4 shows the flow chart of the determination methods of a kind of refuse messages in the specific embodiment of the invention, and the method comprises:
Step S1: client receives note;
Step S2: the characteristic information extracting note, and the characteristic information of note is sent to server end;
Client, after cell-phone customer terminal receives note, extract the characteristic information of note, and the characteristic information extracted is sent to server end, the characteristic information described in present embodiment includes but not limited to that the relation of number in number in the cryptographic Hash of short message content, short message type, note, sender's number, note and recipient, the relation of sender's number and recipient and recipient are to the follow-up action of note.
Wherein, the number in described note comprises telephone number in note and bank's card number; Number in described note and the relation of recipient refer to telephone number in note whether in the contacts list of recipient or in the white list of recipient; Described sender's number and the relation of recipient refer to sender's number whether in the contacts list of recipient or in the white list of recipient; The follow-up action of described recipient to note comprises the number in recovery note, deleting short message, mark note (being labeled as swindle note or advertisement SMS etc.), mark note and marks short message sending person number.
Step S3: according to the characteristic information of note, server end judges whether note is refuse messages.
In this embodiment server end according to the characteristic information received judge note be whether the concrete mode of refuse messages as shown in Figure 4:
First judge whether note is refuse messages according to the number (telephone number in note and/or bank number) in sender's number of note and note, if the number in concrete sender's number or note in the blacklist of server end, then judges that note is refuse messages; If the number in sender's number or note in the white list of server end, then judges that note is normal note.
Optionally, if can not judge whether note is refuse messages according to the number in sender's number of above-mentioned note and note in present embodiment, namely the number in sender's number and note is not all in the blacklist and white list of server end, can again according to short message type, the relation of sender's number and recipient, telephone number in note and the relation of recipient, the accumulative range of the number in note, the cryptographic Hash of short message content and note add up range and judge whether note is refuse messages, concrete: check whether short message type is doubtful black note, whether then uncertain is if not refuse messages, if then judge number in sender's number and note whether all not in the contacts list or white list of recipient, whether then uncertain is if not refuse messages, if then judge whether note meets following arbitrary condition again, if then judge that note is refuse messages, whether then uncertain is if not refuse messages, described condition is:
The accumulative range of the number a. in note is greater than setting threshold; The accumulative range of the number in described note refers to the number of the user of the note received containing the number in this note;
B. the cryptographic Hash of short message content is in the blacklist of server end;
C. the cryptographic Hash of short message content is not in the blacklist of server end, but note adds up range is greater than setting threshold; Described note adds up the number that range refers to the user receiving this note.
Step a and c, adds up range for the accumulative range of the number in note and note, user only accumulative once, namely a user receives same note and repeatedly only calculates a user, does not add up.
Wherein, described judgement of doubting black note is completed by client, and judged result is sent to server end, concrete judgment mode is that client carries out participle to the note received, and the doubtful black dictionary that then inquiry is local, determines the doubtful black word existed in this note, obtain all score values of doubting black word existed in note, if all score value sums of doubting black word are greater than predetermined threshold values, then note is for doubting black note, otherwise is not doubtful black note.
Optionally, if can not judge whether note is refuse messages according to the number in sender's number of above-mentioned note and note in present embodiment, namely the number in sender's number and note is not all in the blacklist and white list of server end, also can judge whether note is refuse messages according to the follow-up action of recipient to note, concrete, if the range of recipient to the follow-up action of note is greater than predetermined threshold value, judge whether the weighted value of each follow-up action is greater than the threshold value adding server end blacklist, if then judge that note is refuse messages, whether then uncertain is if not refuse messages, the range of described recipient to the follow-up action of note refers to that in the note to the identical cryptographic Hash of same, the number of same sender or note, number makes user's number of same treatment action.
For the weighted calculation of each follow-up action, can different account forms be set as required, providing a kind of conventional weighted calculation mode in present embodiment is: the score value arranging each follow-up action, can have just having negative, as recover note can be set on the occasion of, deleting short message, mark note, number in mark note and mark short message sending person number etc. can be set to negative value, the range of each follow-up action is multiplied with its score value and obtains total score value of each action, again total score value of each action is added the weighted value obtaining each follow-up action.
Optionally, if still can not judge whether note is note according to aforesaid way, can judge whether note is refuse messages according to the weighted calculation of all characteristic informations, concrete, process is weighted to all characteristic informations, judge whether the weighted value of all characteristic informations is greater than preset value, if then judge that note is the short breath of rubbish, then judge that note is normal note if not.Certainly, if when can not determine whether note is refuse messages by the way, also directly can judge that note is as note, but if directly judged, likely make indivedual refuse messages skip interception.
After the judgement completing note, if note is refuse messages, the cryptographic Hash of the number in sender's number of note, note and short message content is joined in the blacklist of server end; If whether note is normal note or uncertain note when being refuse messages, whether judge recipient to the weighted value of each follow-up action of note lower than the threshold value removing blacklist set, if then the cryptographic Hash of the number in sender's number of note, note and short message content to be removed the blacklist of server end, then do not process if not.In this embodiment, provide the mode that a kind of cryptographic Hash by the number in sender's number of note, note and short message content counted or removed blacklist, be specially:
Recipient becomes by being less than the threshold values adding blacklist the threshold values being greater than and adding blacklist to the weighted value of each follow-up action of note, and the number in the cryptographic Hash of short message content and note is added blacklist.
Recipient becomes by being greater than the threshold values removing blacklist the threshold values being less than and removing blacklist to the weighted value of each follow-up action of note, and the number in the cryptographic Hash of short message content and note is removed blacklist.
Delete short message content, be labeled as swindle, the score of the actions such as advertisement is greater than the threshold values of setting, adds blacklist.To the number mark in note for swindling, the score of advertisement action is greater than the threshold values of setting, adds blacklist.
Short message content is recovered, is labeled as the normal threshold values waiting the score of action to be greater than setting, short message content is removed blacklist.Be normal to the number mark in note, the score adding the actions such as contact person is greater than the threshold values of setting, and number in note is removed blacklist.
If add blacklist to conflict to some extent with the judgement removing blacklist, add blacklist.
It should be noted that, when carrying out the adding or remove of blacklist, can aforesaid way be adopted, but be not limited to which, different adding and remove rule can be set according to actual needs.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technology thereof, then the present invention is also intended to comprise these change and modification.
