Fig. 2 is the schematic diagram of the system that provides of the embodiment of the invention.
Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the method for the spam filtering that the embodiment of the invention provides may further comprise the steps:
S101: (The Mobile StationISDN number MSISDN) carries out extensively client, and the MSISDN after extensive is sent to the mailbox service end with the international identification code of each contact person's of user travelling carriage;
Wherein, described extensive being meant carried out abstract or obfuscation with certain special object; to reach the purpose that hides Info; in embodiments of the present invention; can't obtain complete contact person MSISDN information by the extensive mailbox service end that can make; therefore, can protect contact person's privacies such as contact method effectively.Concrete extensive method can not done qualification, can select according to actual needs.For example, can use the character of certain obfuscation to replace the mode of precise figures, the extensive method of the character that just can adopt numeral with preset number among the described MSISDN to replace with in the embodiment of the invention to preset (as alphabetical X etc.).Some MSISDN may be repetition after extensive, therefore can also sort according to the rule that presets to the MSISDN after extensive, and the extensive MSISDN that will repeat removes.
Because the user of different identity has secret protection requirement in various degree in the practical application, therefore, the embodiment of the invention can also provide multiple secret protection option to select for the user, and corresponding extensive function is set respectively.The user can select to be fit to the secret protection option of oneself according to the needs of oneself, receives after the secret protection option of user's selection, just can utilize the extensive function corresponding with this secret protection option to carry out extensive to this customer contact people's MSISDN.
S102: the mailbox service end generates described user's filtration matched rule according to described MSISDN after extensive, and with described filtration matched rule and described user's Email Accounts binding;
Though the mailbox service end gets access to is MSISDN after extensive, and the MSISDN after still can be with these extensive serves as according to carrying out the filtration of junk information.Can generate described user's filtration matched rule according to described MSISDN after extensive, then described filtration matched rule and described user's mobile phone Email Accounts is bound, after the binding, this mailbox just can carry out the filtration of junk information by described filtration matched rule.
S103: when the mailbox service termination is received the information mail that sends by portable terminal, call and receive the filtration matched rule of user's Email Accounts binding, the MSISDN and the described filtration matched rule of described portable terminal mated; If described matching result is a matching status, then described information mail is sent to described reception user's portable terminal; Otherwise, described information mail is saved as junk information.
Wherein, when calling and receiving user's the filtration matched rule of Email Accounts binding, the information mail that can at first send according to described portable terminal is resolved and is obtained the MSISDN that receives the user, and the MSISDN with described reception user imports the filtration matched rule that calls with described reception subscriber mailbox number of the account binding then.
Need to prove that the described portable terminal of the embodiment of the invention can comprise mobile phone etc., corresponding contact person's MSISDN is the phone number of saying usually, describes for convenient, hereinafter is described with mobile phone and phone number respectively.
As seen, the embodiment of the invention is to use in the process of network mailbox service the cellphone subscriber, carry out the filtration of junk information according to customer contact people's cell-phone number,, then this information mail can be defined as reliably if promptly the transmit leg of certain information mail is certain contact person of user; Therefore otherwise if the transmit leg of certain information mail is not user's contact person, then this information mail then probably is a spam, it is filtered out, and is concrete, it can be kept in the mailbox, and not send to user's mobile phone.Therefore, can not make in user's the mobile phone and receive harassing and wrecking information, check all information mails that receive but the cellphone subscriber still can login mailbox.
Wherein, the network mailbox service that the described cellphone subscriber of the embodiment of the invention uses is meant: the network mailbox service is supported with mobile phone interconnected, corresponding with service between cell-phone number and Email Accounts function is provided, and the user imports password in mobile phone can login corresponding network mailbox.This network mailbox service can provide network to keep in function, deposit in recent user mobile phone information in the subscriber mailbox of corresponding number of the account with the mail form, and be similar to common mailbox functions, divide receiving emails, not receiving emails and spam etc. the cellphone information mail.The cellphone information forwarding capability can also be provided, and the mailbox service end can send to corresponding cell-phone customer terminal to information mail according to the purpose phone number; The cellphone information type that this network mailbox service can be handled comprises SMS information, mobile phone graph text information and cellphone multimedia information etc.
For the ease of understanding, be described below by concrete example.
1) user opens client software on mobile phone, exists a plurality of options about secret protection therein, and the user selects a kind of secret protection option that is fit to oneself according to self-demand;
Illustrate; as there being four kinds of secret protection safe classes in the cell phone network mailbox service client software; be respectively high; in; lower and low; the user can select a kind of secret protection rank to the different needs of personal secrets protection according to self; if user A is certain star or public figure; to oneself information such as contact person's phone number and take notice of; therefore this user A selects high secret protection rank; user B is a domestic consumer; whether the information such as contact person's phone number of paying no attention to oneself safety; therefore select the middle secret protection rank of acquiescence; user C is busy with one's work; least be ready to be subjected to the interference of junk information, and this user C not too takes notice of the fail safe of privacy information simultaneously, so select low secret protection rank.
Need to prove; about the secret protection rank of the demand of above-mentioned user C and selection contradiction not; because secret protection rank high more (corresponding extensive probability is high more); then the shielded degree of user's associated person information is just high more; but corresponding, the probability that receives junk information is also higher relatively.Therefore, for user C, he is unwilling to be subjected to the interference of junk information, and this user C not too takes notice of the fail safe of privacy information simultaneously, and therefore, the most suitable this user C's is exactly low secret protection rank.Because the secret protection rank is low, corresponding extensive probability is also just low more, like this when carrying out garbage information filtering, may be just low with the probability of extensive numbers match, and then just can play the effect of spam filtering better.
2) according to user-selected privacy protection mode, client-side program is selected corresponding extensive function, is used for contact person's cell-phone number of extensive user;
Illustrate, in cell phone network mailbox service client software, provide four kinds with the secret protection rank to corresponding extensive function, the ratio of its extensive number is respectively 80%, 50%, 20% and 0%, the corresponding secret protection safe class height of difference, in, lower and low, as current domestic phone number is 11, in the extensive function of 80% ratio, extensive 9 item sign indicating numbers wherein, in the extensive function of 50% ratio, extensive 6 item sign indicating numbers wherein, in the extensive function of 20% ratio, extensive 2 item sign indicating numbers wherein, in the extensive function of 0% ratio, extensive 0 item sign indicating number, extensive process is for selecting 9 at random, 6,2 or 0 item sign indicating number preset character to the numeral of respective number position instead of certain, for example letter " X " generates a cell-phone number that comprises letter " X ";
After having selected extensive function, program is called by handset port, obtains the contact person's phone number tabulation in the user contact lists, is input item with each phone number, calls extensive function, and its output is extensive cell-phone number;
For example, certain phone number is 13588247532 in the tabulation, and the extensive ratio of extensive function is 50%, therefore with this number for Entering Number, if function selects number position 2,3,5,7,8 and 10 to be extensive position at random, so the extensive number of its output is 1XX8X2XX5X2.
3) client, sorts to all extensive numbers behind all phone numbers extensive, and ordering rule can be X＞9＞8＞7＞6＞5＞4＞3＞2＞1＞0, goes after the ordering heavily;
For example, there are 6 extensive number: 1XX8X2XX5X2, X38XXXX409X, 1XX8X2XX5X2,135XX80XXXX, XXX888XX1X and X3XX1X785XX, the number that sorts from big to small is: XXX888XX1X, X3XX1X785XX, X38XXXX409X, 1XX8X2XX5X2,1XX8X2XX5X2 and 135XX80XXXX, the extensive number that removes repetition is (in above-mentioned 6 extensive numbers, there are two 1XX8X2XX5X2, therefore one of them is removed), the extensive number collection that finally obtains is: XXX888XX1X, X3XX1X785XX, X38XXXX409X, 1XX8X2XX5X2 and 135XX80XXXX;
Then, just client can be with the packing of extensive number collection, and send to mailbox service end end by secure network protocol (as HTTPS, SSL and WTLS etc.).
4) mailbox service end program Xie Anquanxieyibao, therefrom obtain extensive number collection, with these extensive number collection is input item, generate and filter matched rule, and described filtration matched rule can be configured to filter MM, be used for multiword string coupling, the coupling letter collection that filters the mode bit of coupling automaton is { ' 1 ', ' 2 ', ' 3 ', ' 4 ', ' 5 ', ' 6 ', ' 7 ', ' 8 ', ' 9 ', ' 0 ', ' X ' }, its coupling done state number is the extensive number number of input, its non-coupling done state number is one, for example 3) number collection number is 5 in, therefore there are 6 done states in the filtration coupling automaton that generates according to this number collection, wherein 5 are the coupling done state, respectively corresponding 5 extensive phone numbers, and another is non-coupling done state; That is to say that if coupling then can be as accurate as which extensive phone number of concrete coupling, therefore have 5 kinds of coupling done states, extensive phone number of every coupling is a coupling done state; And if do not match, then only need output not match and get final product, so have only a kind of done state that do not match.
5) generated the filtration matched rule after, the mailbox service end can be according to cellphone subscriber's Email Accounts, filter the bindings of matched rule and cellphone subscriber's Email Accounts, if there has been the filtration matched rule in this Email Accounts, illustrate that this Email Accounts before had been provided with the filtration matched rule, then can carry out and filter the coupling renewal, promptly delete original filtration matched rule, then new filtration matched rule and the binding of this email accounts, in case after finishing bindings, this mailbox just can carry out spam filtering by filtering matched rule.Be exactly the step of specifically carrying out garbage information filtering below.
Suppose that at first cellphone information is transferred to the mailbox service end by sender's cell-phone customer terminal, at the mailbox service end, at first verify the cellphone information form, as mentioned before, the mailbox service end can receive the regular handset messaging format, the information of mobile phone picture and text form and cellphone multimedia form, after checking is passed through, the mailbox service end is converted into the storable mail of network terminal to this cellphone information, it is information mailization, the mail that generates once backs up, the backup mail is deposited in sender's account mailbox, original mail sends to recipient's account mailbox by the inside forwarding capability of mailbox service end, wherein, described recipient's account mailbox generates by recipient's telephone number in the information mail process.Concrete garbage information filtering step is carried out when the account mailbox that receives the user receives mail, specifically may further comprise the steps:
1) recipient's account mailbox is at first judged classification of mail after receiving a mail, if be the general information mail, then enters common flow process, if be the cellphone information mail, then carries out receiving terminal garbage information filtering flow process;
In receiving terminal garbage information filtering flow process, at first reverse resolution obtains recipient's phone number, be input with this number then, call the filtration matched rule of recipient's Email Accounts binding, determine according to matching result whether information mail belongs to junk information, for example, sender's phone number is 13836414096, after filtering the matched rule coupling, the output result is: coupling X38XXXX409X, so this information security; If sender's phone number is 13588543400, after filtering the matched rule coupling, the result is not for matching in output, and then this information mail is the junk information mail;
Need to prove, in this process, because filtering matched rule generates according to extensive number, therefore the arbitrary phone number in the tabulation of contact person's phone number all can be treated to successfully coupling automatically, and a part does not belong to the phone number of contacts list, the match is successful and the phone number that belongs to extensive number range also can be treated to by automaton, for example, according to giving an example in the scheme 1, if it is 13835464098 that there is certain phone number in recipient's contacts list, after extensive, be X38XXXX409X; And this moment, if certain sender's telephone number is 13836414096, then will be confirmed as is safe information mail, but this sender may be in contacts list, and it is junk information that the information that this phone number sends has certain probability.That is to say; when coupling; be more not by each extensive locational numeral, if all consistent, just would be output as matching status; therefore; filter the requirement of coupling and extensive intensity and be inversely proportional to, that is, extensive intensity is high more; the requirement of then filtering coupling low more (because short of be complementary by a few extensive number get final product), this secret protection rank of also further having confirmed the demand of previously described user C and its selection is contradiction not.
2) the cellphone information mail, then filters if information mail is confirmed to be the junk information mail by after filtering, and this information mail is saved in the spam that receives subscriber mailbox, does not re-send to the mobile phone that receives the user; Otherwise information mail is confirmed to be the security information mail, does not then filter, and this information mail once backs up, and is stored in the receiving emails tabulation, and sends to the mobile phone that receives the user.For the latter, the mailbox service end will at first carry out the e-mail messages process, this process is the anti-process of information mailization, promptly, be converted into cellphone information according to Mail Contents and metamessage content, and according to sender's email address and recipient's email address, obtain sender's phone number and recipient's phone number, after this process is finished, then cellphone information is sent to recipient's cell-phone customer terminal, recipient's cell-phone customer terminal is by calling mobile phone build-in function notice and show cellphone information.
Certainly, will be kept in the spam of subscriber mailbox owing to be confirmed as the information mail of junk information, therefore, the user can enter the mailbox of oneself and check.
As fully visible; the embodiment of the invention is compromised between spam filtering and secret protection; in the handling process of whole spam filtering; the mailbox service end can't obtain complete contact person's phone number list content; can only obtain extensive phone number; therefore, can play the effect of protection user privacy information effectively.Though the mailbox service end can be by replacing the exhaustive cell-phone number of alphabetical X in the extensive number with the 1-9 numeral, its probability of success depends on extensive intensity, and extensive intensity is high more, then the probability of exhaustive reduction is just more little, otherwise extensive intensity is low more, and then the probability of exhaustive reduction is just big more; Therefore if user and take notice of oneself privacy information then can select higher extensive intensity.But, though use exhaustive to have certain probability the phone number after extensive can be reduced, can't release method of reducing according to extensive method.As seen, the embodiment of the invention has realized stratified cellphone subscriber's secret protection by phone number is carried out extensive method.
The method of the spam filtering that provides with the embodiment of the invention is corresponding, and the embodiment of the invention also provides a kind of system of filtering spam, and referring to Fig. 2, this system comprises client and mailbox service end, and wherein, described client comprises
