Abstract
The invention discloses an E-mail filter method and system. The method comprises the steps of after the E-mail filter system receives an E-mail, if that the mail communication relation between a sender and a receiver is judged according to the analyzed mail addresses of the sender and the receiver, searching a close communication person table corresponding to the mail address of the receiver and recorded with the mail address of the close communication person of the receiver; if the mail address of the sender is recorded in the close person table, directly delivering the mail into the mail box of the receiver, wherein the close communication person of the receiver is determined according to the communication close degree data of each previously counted user, having mail communication relationship with the receiver, and the receiver. When the sender of the E-mail is the close communication person of the receiver, the E-mail is directly delivered into the mail box of the receiver without other filter treatment, so the resource investment is reduced, and the possibility that the E-mail is wrongly judged as junk mail is reduced.
Description
Technical field
The present invention relates to internet arena, relate in particular to a kind of electronic mail filtering method and system.
Background technology
Spam refers to by " spammer " and just sends to by force the Email in recipient's mailbox without recipient's license.Recipient requires a great deal of time to delete these unwanted spams conventionally, and email service provider need to provide resource to distribute and/or store these spams.Even, some spam also carries malicious file, and these malicious files can destruction of computer systems after activation or stolen important information.Therefore, the Email that conventionally need to send sender carry out filtration treatment, after definite Email is spam, to intercepting junk mail or move on to junk folder.But the algorithm operation of Email being carried out to filtration treatment is more, the possibility that Email is mistaken for spam is just larger, and can take a large amount of cpu resources.
Reduce the misjudged possibility of Email for reducing resource overhead, a kind of existing method is to utilize sender and the previous mail of recipient contact relation and sender's fame data to combine, and Email is carried out to filtration treatment simultaneously.Wherein, mail contact relation between sender and recipient can be direct mail contact relation, in example mail relational network as shown in Figure 1, (B sent Email to C to the relation of B and C, C also sent Email to B), also can be indirect mail contact relation, example B as shown in Figure 1 and the relation of E (the mail contact relation that B and E produce via common third party C).Particularly, the flow process of the electronic mail filtering method of prior art as shown in Figure 2, comprises the steps:
S201: system for filtering E-mails receives after Email, extracts sender's IP and addresses of items of mail and recipient's addresses of items of mail, and whether definite sender's IP and free email domain have corresponding relation.If so, perform step S202; Otherwise, jump to step S210.
Conventionally the IP address that, e-mail system can pre-recorded trusted sender and the corresponding relation of free email domain.Based on this, whether IP and the free email domain that can determine sender have corresponding relation.
S202: whether have direct mail contact relation between system for filtering E-mails inspection sender and recipient.If so, perform step S204; Otherwise, execution step S203.
Particularly, if determine, sender's IP and free email domain has corresponding relation, checks between sender and recipient, whether there is the mail relation of coming and going.First, in this step S202, check between sender and recipient, whether there is direct mail contact relation; If do not exist, further in step S203, check between sender and recipient, whether there is indirect mail contact relation.
S203: whether have indirect mail contact relation between detection sender and recipient.If so, perform step S204; Otherwise, execution step S210.
S204: the fame data based on mail contact relation and sender arrange filtration rank.
Wherein, mail contact relation represents sender and before recipient, carried out intercommunication mutually, namely sent mutually Email.Fame data can be fame marks, for representing that the Email that user sends is the possibility of spam; For example, user's fame mark is lower, and fame is poorer, and the Email of its transmission is that the possibility of spam is just larger.
S210: filter rank and be set to higher filtration rank.
System for filtering E-mails is arranging after the filtration rank of Email, uses the filter based on filtering rank selection to process Email.
For example, in mail relational network as shown in Figure 1, there are A, B, C, D, E, F, seven users of G.In the time that G sends mail to C, owing to there is not mail contact relation between G and C, the filter that the mail that therefore G sends to C can enter higher level carries out filtration treatment.In the time that B sends mail to C, although there is mail contact relation between B and C, due to being in bad odour of B, the filter that the mail that therefore B sends to C also can enter higher level carries out filtration treatment.In the time that E sends Email to C, owing to there being mail contact relation between E and C, and the fame of E is better, and the mail that therefore E sends to C can enter more low-level filter and carry out filtration treatment.
The fame data of above-mentioned electronic mail filtering method based on mail relational network and sender are carried out other setting of filtration grade, and can be found out by logical order wherein, user's mail relational network is that the first order is judged layer, and user's fame data are that layer is judged in the second level.But most mail service provides commercial city that the function that automatically replies of Email is provided.Most user is receiving after spam and can set up mail contact relation with spammer.Like this, in existing electronic mail filtering method, user's mail relational network does not have decisive role in the time carrying out electronic mail filtering, can only serve as auxiliary judgement layer, and fame data just become the crucial layer of judging.This can cause the erroneous judgement of Email under a lot of application scenarioss.
For example, user H is engaged in LED velocitron manufacturing operations, and user H adopts Email Marketing mode to activate business, and has sent the Email that carries in a large number velocitron information.Here it is for not needing the recipient of velocitron spam, and may cause being in bad odour of user H.The recipient who needs velocitron for those, the Email that user H sends is exactly useful information.If had repeatedly mail contact with regard to buying the order of LED velocitron between user H and recipient I.But, if H is in bad odour, the mail that can cause H to send to I still can enter the higher filter of filtration rank and judge, the mail that even H can be sent to I is judged to be spam, thereby it is still higher to cause Email to be mistaken for the possibility of spam, also cause the obstacle of proper communication between H and I, likely can suffer the complaint of I.
Therefore, be necessary to provide a kind of resource overhead not high, and can reduce Email and be mistaken for the electronic mail filtering method of the possibility of spam.

Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is carried out to clear, complete description, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, all other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belong to the scope that the present invention protects.
The terms such as " module " used in this application, " system " are intended to comprise the entity relevant to computer, such as but not limited to hardware, firmware, combination thereof, software or executory software.For example, module can be, but be not limited in: thread, program and/or the computer of the process moved on processor, processor, object, executable program, execution.For instance, the application program of moving on computing equipment and this computing equipment can be modules.One or more modules can be positioned at an executory process and/or thread, and module also can and/or be distributed on a computer between two or more computers.
The present inventor finds, when prior art is carried out fame marking to the user of use Email, adopts unified standard, that is to say that same sender is identical to different recipients' fame data.Like this, same sender is when existing the different recipient of mail contact relation to send Email from it, and e-mail system all adopts identical filtration rank to process.If sender's fame is better, it can adopt lower filtration rank to the Email that exists the recipient of mail contact relation to send with it; On the contrary, if being in bad odour of sender, it all needs to adopt higher filtration rank to the Email that exists the recipient of mail contact relation to send with it.
Based on above-mentioned analysis, in technical scheme of the present invention, according to the level of intimate data of communicating by letter mutually between each user in the mail relational network of adding up in advance, determine each user's close communication people and be recorded in close communication people table.System for filtering E-mails receives after Email, therefrom parse sender and recipient's addresses of items of mail, between the sender that parses and recipient, there is mail contact relation if judge, further judgement and the recipient's who parses addresses of items of mail corresponding, whether the close communication people of the close communication people's that records this recipient addresses of items of mail record the sender's who parses addresses of items of mail in showing; If so, the Email of reception is directly delivered in the recipient's who parses inbox.Therefore, set up respectively close communication people table for each user, level of intimate between employing user is as judgment basis, can avoid the Email that same sender is sent all to adopt identical filtration rank, thereby, reduced the resource overhead of Spam filtering, reduction Email is mistaken for the possibility of spam.
Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
In the embodiment of the present invention, can be according to level of intimate data and the dispersion degree data of communicating by letter between each user in the mail relational network of statistics in advance, the people that communicates by letter with doubtful rubbish shows the close communication people table that periodically updates each user.Particularly, for any the user UserX in mail relational network, communicate by letter with the doubtful rubbish flow process of the method that people shows of the close communication people table that periodically updates user UserX, as shown in Figure 3, comprises the steps:
S301: in the time that each evaluation cycle arrives, for having each user of mail contact relation with user UserX, be related to density data according to what communicate by letter between this user who adds up in this evaluation cycle and user UserX, the level of intimate scoring and the dispersion degree that obtain this user and user UserX are marked.
Particularly, be related to that density data can comprise level of intimate data and dispersion degree data.Level of intimate data can comprise at least one in following data: the achievement datas such as mail session number of times, communication frequency, commitment defini interval and each the independent sessions content topic dispersion of communicating by letter between user.Dispersion degree data can comprise at least one in following data: number of times that the mail of communicating by letter between user is reported, do not read the directly deleted achievement data such as number of times, the number of times not being responded.
In this step, for having each user of mail contact relation with user UserX, according to the level of intimate data of communicating by letter between this user who adds up in this evaluation cycle and UserX, level of intimate to this user and UserX is evaluated, obtain this user's level of intimate scoring, be specifically as follows:
Mail session number of times, communication frequency, commitment defini interval and each the independent sessions content topic dispersion of between this user who adds up within this evaluation cycle respectively and UserX, communicating by letter are as parameter, import in level of intimate evaluation function as shown in Equation 1, level of intimate evaluation function calculates according to the parameter of importing into, and the result calculating is the level of intimate scoring of this user and UserX.
F (x, y, z, k)=w
0x+w
1y+w
2z+w
3k (formula 1)
Wherein, x is mail session number of times, and y is communication frequency, and z is commitment defini interval, and k is each independent sessions content topic dispersion; w
0, w
1, w
2, w
3be respectively the weight of mail session number of times, communication frequency, commitment defini interval, each independent sessions content topic dispersion, specifically set as required by those skilled in the art.
The level of intimate data of communicating by letter between this user who adds up within each evaluation cycle and user UserX, have reflected the level of intimate of communicating by letter between this user and user UserX within this evaluation cycle.For example, the user Y of statistics and the mail session number of times of UserX is more, communication frequency is higher, commitment defini interval is less and each independent sessions content topic dispersion is less in this evaluation cycle, the level of intimate of user Y and user UserX is higher, and the level of intimate scoring of user Y and user UserX is higher.Level of intimate scoring is higher, illustrates that the level of intimate of communication is higher between the two.
In this step, also for having each user of mail contact relation with user UserX, according to the dispersion degree data of communicating by letter between this user who adds up in this evaluation cycle and UserX, dispersion degree to this user and UserX is evaluated, obtain this user's dispersion degree scoring, be specifically as follows:
The number of times reported of mail that this user who adds up within this evaluation cycle respectively sends to user UserX, do not read directly deleted number of times, the number of times that is not responded is as parameter, import in dispersion degree evaluation function as shown in Equation 2, dispersion degree evaluation function calculates according to the parameter of importing into, and the result calculating is the dispersion degree scoring of this user and UserX.
F (r, s, t)=u
0r+u
1s+u
2t (formula 2)
Wherein, r is the number of times that mail is reported, s does not read directly deleted number of times, and t is the number of times not being responded; u
0, u
1, u
2the weight of the number of times that be respectively number of times that mail reported, do not read directly deleted number of times, is not responded, is specifically set as required by those skilled in the art.
The dispersion degree data of communicating by letter between this user who adds up within each evaluation cycle and user UserX, have reflected the dispersion degree of communicating by letter between this user and user UserX within this evaluation cycle.For example, number of times that the mail that user's Y-direction user UserX of statistics sends in this evaluation cycle is reported is more, it is more not read directly deleted number of times number of times more, that be not responded, the dispersion degree of user Y and user UserX is higher, and the dispersion degree scoring of user Y and user UserX is higher.Dispersion degree scoring is higher, illustrates that the dispersion degree of communication is higher between the two.
Like this, be related to density data based on what communicate by letter between user, can obtain existing each user's of mail contact relation level of intimate scoring and dispersion degree to mark with user UserX.
S302: exist each user's of mail contact relation level of intimate scoring and dispersion degree to mark according to what obtain with user UserX, the close communication people who the determines user UserX people that communicates by letter with doubtful rubbish.
Particularly, what evaluation was obtained exists each user's of mail contact relation level of intimate scoring to sort with user UserX, according to ranking results, from existing each user of mail contact relation and choose after the close communicate by letter people of m user as user UserX with user UserX, the close communication people renewal close communication people corresponding with the email address of user UserX who determines according to this shows.For example, can be by the descending sequence of scoring, the close communication people using m forward sequence user as user UserX.Or, choose with user UserX and exist level of intimate scoring in each user of mail contact relation to be greater than the user of the first setting threshold as the close people of communication of user UserX.
And, what evaluation was obtained exists each user's of mail contact relation dispersion degree scoring to sort with user UserX, according to ranking results, from existing and choose n user each user of mail contact relation and communicate by letter after people as the doubtful rubbish of user UserX with user UserX, the doubtful rubbish communication people who determines according to this upgrades doubtful rubbish corresponding with user UserX people that communicates by letter and shows.For example, the descending sequence of marking, the doubtful rubbish communication people using n forward sequence user as user UserX.Or, choose with user UserX and exist user that dispersion degree scoring in each user of mail contact relation is greater than the second setting threshold as the doubtful rubbish of the user UserX people that communicates by letter.
Wherein, m, n are positive integer, and m and n can be the same or different; M, n, the first setting threshold and the second setting threshold are set according to actual conditions by those skilled in the art.
Like this, based on above-mentioned method, after the Email that system for filtering E-mails receives, can, according to the recipient's of predetermined this Email the close communication people people that communicates by letter with doubtful rubbish, carry out filtration treatment to the Email receiving.Particularly, the flow process of the electronic mail filtering method that the embodiment of the present invention provides, as shown in Figure 4, specifically comprises the steps:
S401: system for filtering E-mails receives after Email, therefrom parses sender's IP address and addresses of items of mail and recipient's addresses of items of mail.
Particularly, system for filtering E-mails receives after Email, can from the Email receiving, parse the sender's of this Email IP address and addresses of items of mail, and the sender's of this Email addresses of items of mail.
S402: system for filtering E-mails is searched the IP address that whether records the sender of the Email of reception in IP blacklist, IP white list; If so, this Email is not carried out to other and judge, directly this Email is processed; Otherwise, execution step S403.
Particularly, system for filtering E-mails is searched the IP address that whether records the sender of the Email parsing in IP blacklist, IP white list.If record this IP address in IP blacklist, show to tackle this Email, no longer this Email is carried out to other and judge, directly this Email is deleted.If record this IP address in the white list of IP address, show that the Email that this IP address sends is Email trusty, Email is not carried out to other and judge, directly this Email is delivered in recipient's inbox.Wherein, the spammer's that the IP address in IP blacklist determines before can being IP address; The trusted sender's that IP address in IP white list has been determined before can being IP address.
S403: whether system for filtering E-mails, according to the sender who parses and recipient's addresses of items of mail, exists mail contact relation between the sender that judgement parses and recipient; If so, perform step S404; Otherwise, jump to step S410.
Particularly, system for filtering E-mails can be in advance according to the relation of communicating by letter between each user in customer relationship network, and the user's who sent mutually Email the corresponding relation of addresses of items of mail is stored in mail contact relation table.In this step, system for filtering E-mails is searched the corresponding relation that whether records sender's the addresses of items of mail of the Email parsing and the recipient's of this Email addresses of items of mail in mail contact relation table, if, judge and between the sender of this Email and the recipient of this Email, have mail contact relation, otherwise, judge and between the sender of this Email and the recipient of this Email, do not have mail contact relation.
