In step S401, the CPU201 of acting server 101 accepts condition for the Email of retrieval reading object from supervisory person, the Email that meets from form retrieval shown in Figure 7 and this condition.As search condition, can be as shown in Figure 6, the condition of setting-up time, utilize the condition of keyword etc.
If accepted the input of search condition via picture shown in Figure 6, and accept pressing of index button 601, then carried out retrieval.Retrieval process herein is equivalent to the processing that the Email as supervisory object reduced the scope for supervisory person.
In step S402, the CPU201 of acting server 101 is presented at the result who retrieves among the step S401.Fig. 8 is an example of the result for retrieval guide look picture that shows in step S402.
Example shown in Figure 8 illustrates the result who has retrieved the data of Fig. 7 by search condition shown in Figure 6 (sent, and comprised the Email of the character string that " meeting material " is such in 00: 00 ~ 24: 00 on December 20th, 2011).
In step S403, the CPU201 of acting server 101 accept in the Email that shows in the result for retrieval guide look picture (Fig. 8) that in step S402, demonstrates, as the selection of the Email of supervisory object (reading object), show the detailed content of the Email of selecting.Fig. 9 is an example of picture displayed in step S403 (supervisory picture).
In supervisory picture shown in Figure 9, show the Email of supervisory object the sender, send information (901) such as destination, part name, date of shipping time.In addition, the text (902) that shows Email.
In addition, under the situation of having added file, show the situation of appended document, at each file, shown that being used for selection obtains the check box of still not obtaining.
For example, illustrate supervisory object mail shown in Figure 9 has been added " meeting material " and " reference " these 2 files.
So if selected the check box shown in the appended document 903, then " meeting material " file by password protection and these both sides of " reference " file are set to and obtain object.
Respectively " meeting material " file, " reference " file are set at independently and obtain object under the situation of 904,905 check box having selected.
For appended document (unprotect) 906, it is the check box that shows under the situation of file additional after the processing of having carried out step S409 or in not by the Email of the supervisory object of password protection.If selected 906, the file of then having deciphered (unprotected file) is set to obtains object.
Similarly selecting under the situation of 906 check box with 903 ~ 905 check box, meeting material, these both sides of reference are set to and obtain object.Selecting under the situation of 907,908 check box, each file is chosen as independently obtains object.
By after having selected some in 903 ~ 908, press appended document and obtain button 909, accept appended document and obtain indication (step S404).
In step S404, the CPU201 of acting server 101 obtains indication (obtaining pressing of button 909 by the appended document of Fig. 9 accepts) via the supervisory picture that demonstrates from what supervisory person accepted appended document additional the Email of this supervisory object in step S403.
Obtain button 909 herein, and also can only under the situation of the Email that becomes supervisory object having been added appended document, show (perhaps can press).
In step S405, the CPU201 of acting server 101 judges that whether accepted the appended document of obtaining indication in step S404 is file by password protection.That is, judge when this appended document of reading, whether need the input of password.
Being judged as in step S405 is (step S405: "Yes"), make to handle and transfer to step S407 under the situation of the file by password protection.
Being judged as in step S405 is not (step S405: "No"), make to handle and transfer to step S406 under the situation of the file by password protection.
In step S407, the Email (password record mail) of required password for read (supervisory) is designated as the appended document of Email of supervisory object has been recorded and narrated in the CPU201 of acting server 101 retrieval.Use the flow chart of Fig. 5, the detailed content of the retrieval process among the aftermentioned step S407.
, use Fig. 5 herein, illustrate that the password that acting server 101 in embodiments of the present invention carries out records and narrates mail retrieval process (detailed content of the processing of step S407).
In addition, for the processing shown in the flow chart of Fig. 5, be that the CPU201 of acting server 101 reads and the processing of the control program that puts rules into practice.
In step S500, the CPU201 of acting server 101 obtains the relevant archived markings of Email that sends after the time with the date of shipping of the Email that is selected as supervisory object in step S403 from mail archived markings (Fig. 7).
Password is recorded and narrated mail in that only then to be designated as situation about being sent out after the Email of supervisory object more.That is, just sending with after the file of password protection, the situation that sends password record mail in order to notify this password is more.Therefore, can be by as the processing of step S500, the data of the Email that priority treatment sends after the time at the date of shipping of the Email of supervisory object, and find password record mail efficiently.
In this case, the Email that sends after the time on date to the Email that sent supervisory object has been carried out after the later processing of step S502, carries out the processing (describing in detail in step S511) at remaining Email (at the Email that sends before the Email than supervisory object).
In step S501, the CPU201 of acting server 101 reads in the mail data that 1 row is measured from the mail archived markings that obtains among step S500.
In step S502, the CPU201 of acting server 101 judges the mail read in step S501 recipient information (transmission source, send the destination) the whether recipient information with the Email of supervisory object is identical.
Be judged as identical situation (step S502: "Yes"), make to handle and transfer to step S503.
Be judged as different situations (step S502: "No"), make to handle and transfer to step S507.
In step S503, the CPU201 of acting server 101 judges the mail read in step S501 the part name whether part name with the Email of supervisory object is identical.
Be judged as identical situation (step S503: "Yes"), make to handle and transfer to step S504.
Be judged as different situations (step S503: "No"), make to handle and transfer to step S507.
In step S502, whether be all benchmark mutually with recipient information.The Email (password record mail) that is used for the password of reading this document for the Email (having added the Email by the file of password protection) of supervisory object and notice; the transmission source sends the destination, and all identical situation is more; so by judging according to such condition, can access suitable result for retrieval.
In addition, even the not processing shown in the execution in step S502 also can retrieve password be recorded and narrated mail, purpose of the present invention can be reached.
In addition, for the processing among the step S503, also be based on the more processing of situation that sends supervisory object Email and password record mail by same name.Therefore, even the not processing shown in the execution in step S503 also can retrieve password be recorded and narrated mail, purpose of the present invention can be reached.
In addition, in step S503, whether " identical " is benchmark with the part name, but also records and narrates in the part name of mail at password sometimes, appends " password notice " such character string and send in the part name of supervisory object Email.In addition, also send by " password notice " such part name simply sometimes.
Therefore, the processing of step S503 also can be to judge the whether identical processing of part of having removed " password notice " such character string from the part name.
Perhaps, also can be that the Email that will for example comprise the character string that " password notice " is such in the part name is defined as the processing that reduces the scope that the candidate of mail recorded and narrated in password.
In addition, with the processing of step S502 similarly for the condition among the step S503 owing to be for finding that password records and narrates an example of the condition of mail, so be not limited to this condition, and also can retrieve by other conditions.
In step S504, the CPU201 of acting server 101 obtains the textual data of the Email that reads in step S501.
In step S505, whether record password in the beginning part of the textual data that the CPU201 of acting server 101 judgement obtains in step S504.
Record and narrate situation (the step S505: "Yes"), make to handle and transfer to step S506 that password is arranged being judged as.
Record and narrate situation (the step S505: "No"), make to handle and transfer to step S507 that password is arranged being judged as not.
As the text of password record mail, for example consider " password of the file of Fa Songing was * * * * just now " such content.Therefore, in step S505, use technique known such as approximate literary composition retrieval to retrieve to comprise the Email with the approximate character string of such " password is * * * * " such character string, judge whether that record has password.
In addition, in step S505, judge in the beginning part of text, whether to have recorded and narrated password, but be not limited to the beginning part, if also can record and narrate above-mentioned character string in the somewhere in text, then be judged as and recorded and narrated password.
In addition, also can also be judged as "Yes" for the Email of not recording and narrating concrete password.
For example, as the character string approximate with " password is * * * * " such character string, can think " password is identical always " such character string.For the Email of having recorded and narrated such character string, can't say and record and narrate concrete password.But, record and narrate the mail candidate if such Email can be prompted for password in aftermentioned step S509, then for the user, can grasp the password that should use.
That is, even can't learn concrete password, also for example can grasp " be not only this special password and can decipher by the password that uses always ".
Like this, the processing among the step S505 is the retrieval Email (password record mail) of having recorded and narrated concrete password, the Email of the information of having recorded and narrated the such password of expression " identical always " etc. recorded and narrated the processing of Email that expression is used for the information of password that file is decrypted.
In step S506, the CPU201 of acting server 101 will be judged to be "Yes" in step S505 e-mail storage is the candidate that mail recorded and narrated in password.
In step S507, the CPU201 of acting server 101 judges whether at after having carried out step S511 at step S500(, step S511) in the archived markings of reading in the underlined processing of carrying out step S502 ~ S506.
Be situation (the step S507: "Yes"), make to handle and transfer to step S508 of last mark being judged as.
Be judged as the also situation of interlocutory mark (step S507: "No"), make to handle to turn back to step S501, read in ensuing mail archived markings.
Above-mentioned processing shown in Figure 5 is to record and narrate mail and extract an example of the processing of password out for definite password, even constitute by the retrieval of the treatment step beyond it and determine that password records and narrates mail, problem of the present invention also can solve.
In step S508, the CPU201 of acting server 101 judges whether to have found password record mail.Particularly, be judged to be "Yes" according to having or not in step S505, and the data that are stored in storage area in step S506 are judged.
At the situation of having found password record mail (step S508: "Yes"), make to handle and transfer to step S509.
At the situation of not finding password record mail (step S508: "No"), make to handle and transfer to step S510.
In step S509, the CPU201 of acting server 101 makes the picture of the candidate guide look that shows password record mail be shown in supervisory person's terminal 107.Then, the processing shown in the process ends figure.
Figure 10, Figure 17, Figure 18 are illustrated among the step S509, at an example of supervisory person's terminal 107 picture displayed.
Figure 10 is the example that mail candidate guide look picture recorded and narrated in password.In the candidate guide look display part 1001 of picture shown in Figure 10, the guide look demonstration is judged as the mail that might put down in writing for the password of the additional file of the Email of the supervisory object of reading by the processing shown in the flow chart of Fig. 5.That is, be presented at the Email that is stored in storage area among the step S506.
In picture shown in Figure 10, illustrate and select by the definite mail of part name " password notice: the meeting material of yesterday ", in Mail Contents display part 1002, show part name, recipient information, the date of shipping time of this mail, the content of message body etc.For the password in the text, can show with identifying.
For the method from password record mail extraction password, owing to can realize by the known technology of both having deposited, so detailed explanation omission, but an example is described herein.
For example, consider will and then " password: " such character string be defined as the such method of password afterwards.In addition, also can use known technology to detect the character string approximate with " password is * * * * " such character string, and the part suitable with * * * * is defined as password.Method shown in being not limited thereto, and can use any known technology.
In the picture of Figure 10, password application button 1003 is arranged, by pressing this button, use the password of recording and narrating in the selected Email that goes out, file additional in the Email of supervisory object is decrypted (step S409).
In addition, in Figure 10, show and retrieve the example that the situation of mail recorded and narrated in a plurality of passwords.But recording and narrating mail at password only is under the situation of 1 envelope, also can not wait for pressing of password application button, and use the password of recording and narrating in this mail automatically.
Figure 17 does not carry out the sender, sends whether identical judgement of destination, and the Email that will comprise the such character string of pass word simply in message body, part name is had a guide look of the example of demonstration as candidate.
Though not shown in Figure 17, also can possess password application button as shown in Figure 10, password input field as shown in Figure 18.Perhaps, also can in different pictures, show password input picture.
Figure 18 is in the picture of Figure 10, is provided with the picture of password input field 1803.In picture example shown in Figure 180, by being entered password in password input field 1803 by supervisory person, and press password application button 1804, and use the password of importing file additional in the Email of supervisory object is decrypted (step S409).
Like this, show together that by making password record mail and password input field supervisory person can enter password in the text of observing password record mail.
In step S510, the CPU201 of acting server 101 judges whether archived markings that the Email that sent before the time with date of shipping at the Email that is selected as supervisory object is relevant and the mark of the processing of execution in step S501 ~ S507 not.
At situation about being judged to be (step S510: "Yes"), make to handle and transfer to step S511.
At situation about not having (step S510: "No"), make to handle and transfer to step S512.
In step S511, the CPU201 of acting server 101 obtains the relevant archived markings of Email that sent before the time with date of shipping at the Email that is selected as supervisory object.Then, make to handle to turn back to step S501, to the processing of mark execution in step S501 ~ S507 of in step S511, obtaining.
In step S512, the CPU201 of acting server 101 makes the error picture of the situation of not finding password record mail be shown in supervisory person's terminal 107, the processing shown in the process ends figure.
Figure 16 is illustrated among the step S512 example of picture displayed in supervisory person's terminal 107.
In addition, for the processing of step S510, S511, be not to be the essential processing in order to reach purpose of the present invention, so can not carry out yet.That is, only the mail archived markings that obtains is being carried out the processing of S501 ~ S507 in step S500, and do not found that password records and narrates (step S508: "No"), also may be controlled to transfer to step S512, and show error picture under the situation of mail.
By the such execution in step S510 of the processing shown in this flow chart, S511, can find password with not omitting and record and narrate mail.
In addition, in the present embodiment, constitute the picture that in the processing of step S508, shows Figure 10, point out the candidate of password record mail to supervisory person, but this processing is not the essential processing in order to reach purpose of the present invention.That is, the not processing of execution in step S508, and record and narrate the password of recording and narrating in the mail by the password of in step S506, finding, carry out decryption processing (S409), thereby problem of the present invention can solve.
In addition, do not carry out the processing of step S500, S510, S511, and from the beginning at all mail archived markings, the processing of step S501 ~ S506 repeatedly.
Turn back to the explanation of Fig. 4.
In step S408, the CPU201 of acting server 101 judges whether to have accepted from supervisory person the input of password.
For example, in the picture of Figure 10, select some passwords to record and narrate mail, and supress under the situation of password application button 1003, be judged as the input of having accepted password.
In addition, in the picture of Figure 18, in password input field 1803, enter password, and supress under the situation of password application button 1804, be judged as the input of having accepted password.
In addition, in the error picture of Figure 16, in password input field 1601, enter password, and supress under the situation of OK button, be judged as the input of having accepted password.
On the other hand, under the situation of the cancel button in supressing Figure 10, Figure 18, Figure 16 (1004,1805,1603), be judged as the input of not carrying out password.
Situation (step S408: "Yes"), make to handle and transfer to step S409 in the input of having accepted password.
Situation (step S408: "No"), make to handle and transfer to step S406 in the input of not accepting password.
In step S409, the CPU201 of acting server 101 uses the password of having accepted input in step S408, carries out having received in step S404 the deciphering (being made as the state that can read) of the appended document of obtaining indication.
Herein, for the file of in step S409, deciphering, with the Email that the is designated as supervisory object storage that is mapped.
Thus, in step S404, accepted under the situation that obtains indication of the file of removing password, the file of deciphering can have been sent to supervisory person in step S409.Thus, need not the processing shown in the flow chart of each execution graph 5, so can realize the high efficiency handled.
In step S410, the appended document that the CPU201 of acting server 101 will decipher in step S410 sends to supervisory person (office terminal).Then, the processing shown in the process ends figure.
Being judged as in step S405 is not that the situation of the file by password protection and being judged as in step S408 does not find that password records and narrates under the situation of mail, directly file is sent to supervisory person in step S406.Then, the processing shown in the process ends figure.
＜the 2 execution mode 〉
Next, use Figure 11, Figure 12, the 2nd execution mode of the present invention is described.In the 2nd execution mode, be that " password is the password that always uses " is such even record and narrate mail at for example password, use under the situation of the password that passes through email notification in the past repeatedly, also can determine password efficiently.
In Figure 11, the password preservation processing that acting server 101 carries out in the 2nd execution mode is described.
In addition, for the processing shown in the flow chart of Figure 11, be that the CPU201 of acting server 101 reads and the processing of the control program that puts rules into practice.
In step S1101, the CPU201 of acting server 101 receives the Email that sends from client terminal device 103.
In step S1102, the CPU201 of acting server 101 judges whether the Email that receives is that mail recorded and narrated in password in step S1101.
Be situation (the step S1102: "Yes"), make to handle and transfer to step S1103 that mail recorded and narrated in password being judged as.
Be judged as be not the password situation of recording and narrating mail (step S1102: "No"), the processing shown in the process ends figure.
Whether specify among the step S1102 is the determination methods that mail recorded and narrated in password.
Record and narrate mail for password, the situation of importing " password is * * * * " such character string in the such character string of input " password notice " in the part name of Email, " contact of password ", the text at Email is more.Therefore, can be judgment standard whether to comprise such character string.In addition, can also be simply be judgment standard whether to comprise the such character string of pass word.In addition, can also use technique known such as being similar to the literary composition retrieval to judge whether to comprise the character string approximate with above-mentioned " password is * * * * ".
Like this, for whether being the judgement that mail recorded and narrated in password, can realize by the known technology of both having deposited, can use any means.
In step S1103, the CPU201 of acting server 101 records and narrates the Email of mail from be judged as password among step S1102, extracts password out, is registered in password DB(as an example, Figure 13).At this moment, in this password DB, information and passwords such as registration transmission source, transmission destination, date of shipping time are mapped.
For recording and narrating the method that mail is extracted password out from password, can realize by the known technology of both having deposited, so though detailed explanation is omitted, an example is described herein.
For example, consider will and then " password: " such character string be defined as the such method of password afterwards.In addition, also can use known technology to detect the character string approximate with " password is * * * * " such character string, and the part suitable with * * * * is defined as password.As mentioned above, the method shown in being not limited thereto, and can use any known technology.
Next, use Figure 12, the appended document decryption processing in the present embodiment is described.
In addition, in Figure 12, to the processing shown in the flow chart of Fig. 4, append the processing of step S1201 ~ S1207, and deleted step S407, S408.Therefore, herein, the only processing of description of step S1201 ~ S1207.Other processing are identical with the processing of the Fig. 4 that illustrates in the 1st execution mode.
In step S1201, the CPU201 of acting server 101 is from password DB(Figure 13) retrieval is used for having carried out the password that the appended document of protection is decrypted to being judged as at step S405 by password.At this moment, use the transmission source of the Email (supervisory object mail) that has added this document, the information of transmission destination to retrieve.
Particularly, from the consistent data in transmission source and transmission destination of password DB retrieval and supervisory object mail.
Herein, even when retrieve password DB, the project that also can preferentially retrieve the date of shipping time is the data of the date time of date of shipping after the time of supervisory object mail.Thus, retrieve password more efficiently.
In step S1202, the CPU201 of acting server 101 judges whether to have found consistent data by utilizing the retrieval process of step S1201.
At the situation of having found consistent data (step S1202: "Yes"), make to handle and transfer to step S1206.
