Description

  The present invention relates to a technique for sorting e-mails and the like.

  In order to suppress reception of so-called junk mail (also referred to as spam), there is a technique for controlling reception of an electronic mail based on a mail address. Such technology includes, for example, one that selectively permits or rejects reception of an e-mail having a specific domain name (see, for example, Patent Document 1).

JP 2007-134776

In order to selectively permit or reject the reception of an electronic mail, it is common to register a character string (domain name, mail address, etc.) by the user. The number of character strings that can be registered is generally limited to a certain number for each user. If it does so, the user who has registered the character string to the upper limit needs to perform selection when registering a new character string.
Therefore, an object of the present invention is to reduce the user's effort for selection when selectively permitting or rejecting reception of an electronic mail.

An information processing apparatus according to the present invention is assigned to an acquisition unit that acquires a character string included in a mail address of a transmission source that is permitted to be received by a transmission destination, and a transmission source of an electronic mail that is destined for the transmission destination. A classification means for classifying the received email addresses into a plurality of groups depending on whether or not they include any of the character strings acquired by the acquisition means, and the email addresses classified into any groups by the classification means Output means for outputting notification data for notifying the number of times the transmission source e-mail is received by the transmission destination in units of the group.
Alternatively, an information processing apparatus according to the present invention provides an acquisition unit that acquires a character string included in a mail address of a transmission source that is refused reception by a certain transmission destination, and a transmission source of an e-mail that has the transmission destination as a destination. Classification means for classifying the assigned email address into a plurality of groups depending on whether or not the character string acquired by the acquisition means is included, and email addresses classified into any group by the classification means It has a structure provided with the output means which outputs the alerting | reporting data for alerting | reporting the frequency | count of transmission by the said transmission source of the email of the allocated transmission source by the said group unit.

  The data stored in the storage unit 120 includes a character string designated by the user of the mobile communication terminal 200. Hereinafter, this character string is referred to as a “designated character string”. The designated character string is a character string that represents a part or all of the mail address, and is included in the mail address of the transmission source that the user of the mobile communication terminal 200 has permitted to receive. The designated character string is preferably part or all of the domain name and does not include the user name.

The data stored in the storage unit 120 includes the number of e-mails sent to the mobile communication terminal 200 (hereinafter referred to as “number of transmissions”) and the number of e-mails received by the mobile communication terminal 200. (Hereinafter referred to as “the number of receptions”). The number of transmissions and the number of receptions are transmitted from the mail server 300 in this embodiment. However, the reception count may be transmitted from the mobile communication terminal 200.
Note that the number of transmissions and the number of receptions can be calculated at various points in time. The number of times of transmission and reception may be, for example, a value counted from the time when the user starts using the corresponding mail address, or a value for a predetermined period (for example, the most recent month, one year, etc.) It may be.

  FIG. 3 is a block diagram illustrating a configuration of the mobile communication terminal 200. As shown in the figure, the mobile communication terminal 200 includes a control unit 210, a storage unit 220, a communication unit 230, an operation unit 240, and a display unit 250. The control unit 210 includes an arithmetic processing unit and a memory, and controls the operation of each unit of the mobile communication terminal 200 by executing a program. The storage unit 220 includes a storage medium such as a flash memory, and stores data necessary for the control unit 210 to execute processing.

The operation unit 240 supplies operation information representing the received operation to the control unit 210. The display unit 250 includes a display element using liquid crystal, organic electroluminescence, and the like and a drive circuit, and displays an image corresponding to data supplied from the control unit 210 in a display area configured by the display element. To do. The display unit 250 is an example of a display unit according to the present invention.

  The mobile communication terminal 200 can execute at least a function corresponding to an e-mail client (so-called mailer) and a function for causing the server device 100 to record the designated character string by executing the program. The recording of the designated character string in the server device 100 is also referred to as “registration” below. This registration function may be a function attached to the e-mail client, or may be a function separated from the e-mail client, for example, executed using a Web browser. The mobile communication terminal 200 desirably has a function corresponding to a so-called address book, and can store information on a transmission source such as a mail address.

The mail server 300 is a server device that relays electronic mail addressed to the mobile communication terminal 200. The mail server 300 receives the email addressed to the mobile communication terminal 200 transmitted from the external communication terminal 400, and transmits it to the mobile communication terminal 200 as necessary. The timing at which the mail server 300 transmits an e-mail to the mobile communication terminal 200 may be any time after determining whether reception is permitted, immediately after such determination, or the mobile communication terminal 200. It may be the timing requested from. In the present embodiment, for convenience of explanation, the mail server 300 is configured separately from the server apparatus 100, but the function of the mail server 300 may be executed by the server apparatus 100.
The external communication terminal 400 includes at least a configuration necessary for transmitting an e-mail. The external communication terminal 400 may have the same configuration as the mobile communication terminal 200, for example.

  FIG. 4 is a functional block diagram illustrating functions realized by the server device 100. The control unit 110 of the server apparatus 100 implements functions corresponding to the character string acquisition unit 111, the address acquisition unit 112, the classification unit 113, the output unit 114, and the recording control unit 115 illustrated in FIG. .

  The character string acquisition unit 111 acquires the designated character string transmitted from the mobile communication terminal 200 via the communication unit 230. The designated character string acquired by the character string acquisition unit 111 includes at least a character string included in an email address that the user desires to receive. Such a designated character string is hereinafter referred to as a “designated received character string”. The specified character string acquired by the character string acquiring unit 111 is more preferably a character string (hereinafter referred to as “excluded character string”) included in an e-mail address that the user does not want to delete by the server device 100, and the user. Includes a character string desired to be weighted (hereinafter referred to as “weighted character string”).

  Of the functions of the character string acquisition unit 111, the function of acquiring a designated received character string corresponds to an example of an acquisition unit according to the present invention. Of the functions of the character string acquisition unit 111, the function of acquiring the excluded character string is included in an example of the first setting unit of the present invention, and the function of acquiring the weighted character string is the second function according to the present invention. Is included in an example of the setting means. The functions relating to the first setting means and the second setting means are additional functions of the character string acquisition unit 111, and may be realized by a configuration in which the character string acquisition unit 111 does not have the function.

  The address acquisition unit 112 acquires the mail address (or domain name) assigned to the transmission source of the email transmitted to the mobile communication terminal 200 from the mail server 300 via the communication unit 230. The address acquisition unit 112 acquires the above-described transmission count and reception count for each mail address (or domain name). That is, the address acquisition unit 112 acquires data indicating how much e-mail from which mail address (or domain name) has been transmitted and how much has been received.

  The classification unit 113 corresponds to an example of classification means according to the present invention. The classification unit 113 classifies the mail addresses (or domain names) acquired by the address acquisition unit 112 into a plurality of groups depending on whether or not any of the designated received character strings is included. The classification by the classification unit 113 is performed by comparing whether or not the mail address (or domain name) matches the designated received character string. This comparison is by partial match, preferably by backward match. However, here, if the designated received character string is a domain name and the domain names are compared with each other, a complete match may be performed. The classification unit 113 classifies mail addresses (or domain names) including designated received character strings into groups for each designated received character string, and one or a plurality of mail addresses (or domain names) not including the designated received character string. Classify into groups. Email addresses (or domain names) that do not include the designated received character string may form one group as a whole, but groups that include a common character string may also be formed.

The output unit 114 corresponds to an example of output means according to the present invention. The output unit 114 uses the classification result of the classification unit 113 to report data for notifying the number of times of reception for each classified group for an email that is permitted to be received (hereinafter referred to as “notification data”). Is output. The notification data is transmitted to the mobile communication terminal 200 via the communication unit 230. The broadcast data includes the number of receptions for at least one of the classified groups.
Note that the output unit 114 may notify the e-mail that is not permitted to be received, together with the number of times of transmission in the classified group unit, using the classification result by the classification unit 113. In this case, the broadcast data includes the number of transmissions and the number of receptions.

  The recording control unit 115 corresponds to an example of a recording control unit according to the present invention. The recording control unit 115 records the designated character string acquired by the character string acquisition unit 111 in the storage unit 120. The designated character string recorded by the recording control unit 115 functions as an effective character string. Here, “effective” means that the effect of permitting reception is produced. On the other hand, a state where the designated character string is not valid, that is, a state where reception is not permitted is hereinafter referred to as “invalid”. The invalid character string may be deleted from the storage unit 120 by the recording control unit 115. However, if data such as a flag for distinguishing whether the character string is valid or invalid is added to the designated character string stored in the storage unit 120, It may not be erased from the storage unit 120.

  The valid designated character string stored in the storage unit 120 is transmitted to the mail server 300 at a predetermined timing, and is copied to a storage unit included in the mail server 300. The mail server 300 uses this designated character string for determining whether or not to send an e-mail to the mobile communication terminal 200. Therefore, the recording control unit 115 may record the designated character string in the storage unit of the mail server 300 instead of recording the designated character string in the storage unit 120.

  The configuration of the communication system 10 of the present embodiment is as described above. Under this configuration, the external communication terminal 400 that is the transmission source generates and transmits an e-mail addressed to the mobile communication terminal 200. The mail server 300 relays the electronic mail from the external communication terminal 400, and determines whether or not to transmit the electronic mail to the mobile communication terminal 200 in accordance with the designation by the user of the mobile communication terminal 200 that is the transmission destination. . The mail server 300 prevents the mobile communication terminal 200 from transmitting an electronic mail from a transmission source that the user of the mobile communication terminal 200 does not want to receive.

  Server device 100 also accepts registration of a designated character string from the user of mobile communication terminal 200. This registration may be performed one by one, or several or all cases may be performed together. The registered designated character string is used in the mail server 300 to determine whether or not to send an e-mail to the mobile communication terminal 200. The number of cases where the designated character string can be registered is limited to a certain value (for example, 40) per user, and that value is preset as a threshold value.

  The server apparatus 100 according to the present embodiment executes the processing of each operation example described below in view of such restrictions. Here, for convenience of explanation, each operation example will be described separately. However, the server apparatus 100 can execute a combination of the processes of each operation example. In the following description, it is assumed that the designated character string is a part or all of the domain name.

(Operation example 1)
FIG. 5 is a flowchart illustrating an example of processing executed by the server apparatus 100 to output notification data. This process is executed when the user of the mobile communication terminal 200 requests registration or confirmation of the designated received character string. As shown in the figure, the control unit 110 of the server device 100 acquires a designated reception character string from the mobile communication terminal 200 and also acquires a transmission count and a reception count for each domain name from the mail server 300 (Step S101, S102). The order of the processing of step S101 and step S102 may be reversed.

  The control unit 110 classifies the domain names into a plurality of groups using the data acquired in steps S101 and S102 (step S103). At this time, the control unit 110, for example, includes a domain name group including a specified reception character string, a domain name group including another specified reception character string, and a domain name group including no specified reception character string. Categorize domain names. Subsequently, the control unit 110 ranks the classification results according to the number of transmissions or the number of receptions, and gives a rank to each classified group (step S104). Then, the control part 110 produces | generates notification data based on this ranking, and outputs it (step S105). The control unit 110 supplies the notification data to the communication unit 130 and transmits the notification data to the mobile communication terminal 200. When receiving the notification data, the mobile communication terminal 200 causes the display unit 250 to display the content represented by the notification data.

  FIG. 6 is a diagram illustrating an image displayed on the display unit 250 of the mobile communication terminal 200 and having contents represented by the notification data. In the figure, the image represented by the notification data includes a reception permission list and a reception rejection list. The reception permission list is a list indicating the domain names that the user of the mobile communication terminal 200 is permitted to receive together with the number of receptions. The reception rejection list is a list indicating, together with the number of transmissions, the domain name that the user of the mobile communication terminal 200 has not transmitted to the terminal. Note that it is not necessary to display all of the corresponding domain names in these lists, and only a part of the domain names corresponding to the given order may be displayed.

  In this example, the reception permission list is displayed in order from the smallest reception frequency. The domain name is displayed in the text boxes T11, T12, T13,... And can be rewritten by the user. Here, when the user rewrites the domain name and selects (clicks, etc.) the change buttons B11, B12, B13,... Corresponding to the rewritten domain name, the rewritten domain name is registered as a designated received character string. At this time, the designated received character string before rewriting becomes invalid, and the designated received character string after rewriting becomes valid. Also, when the user registers with the text box blank (no character), the designated received character string is deleted. When such deletion is performed, the number of designated received character strings that can be registered increases.

  In addition, the reception rejection list is displayed in descending order of the number of transmissions. Here, when the user selects a registration button B21, B22, B23,... Corresponding to a domain name desired to be registered, the selected domain name is registered as a new designated received character string. Such registration can be performed until the number of registrations reaches the upper threshold.

  The mark M21 added corresponding to the domain name in the reception rejection list is a mark indicating that there is a high possibility that the domain name is a domain name of spam mail. Here, the determination as to whether the domain name is that of a spam mail can be made based on the status of registration by a plurality of users, for example. For example, if it is a domain name registered by a certain number of users, it is judged that there is a low possibility that the domain name is spam, or if it is a domain name that most users do not register, spam mail It is possible to determine that there is a high possibility that the domain name is. Alternatively, such a determination may be made by a telecommunications carrier operating the mail server 300.

As described above, according to this example, the user of the mobile communication terminal 200 can register, change, and delete the designated received character string while confirming the number of receptions and the number of transmissions. By checking the number of receptions, the user can specify a domain name that has relatively little effect due to designation. In addition, by confirming the domain name and the number of transmissions, the user must newly register a domain name that is not permitted to be received (or that can be received without any problem). Is possible. In this way, the user can obtain suggestions regarding selection of the designated received character string.
Note that the broadcast data may include content corresponding to the above-described reception permission list and not including content corresponding to the reception rejection list.

(Operation example 2)
This example shows the operation when the number of registrations by the user of the mobile communication terminal 200 reaches the upper limit. That is, the operation of this example is performed when the user requests registration of a new designated received character string when the number of registrations by the user reaches the upper limit.

  FIG. 7 is a flowchart illustrating processing executed by the server device 100 when the number of registered registered received character strings reaches the upper limit. As shown in the figure, when the control unit 110 acquires a new designated received character string (step S201), the control unit 110 counts the valid designated received character string stored in the storage unit 120, whereby the registration number is the upper limit threshold value. Is determined (step S202). If the number of registrations is less than the threshold, the control unit 110 records the newly acquired designated received character string as valid in the storage unit 120 (step S203).

On the other hand, when the number of registrations is equal to the threshold value, the control unit 110 identifies the designated received character string with the smallest number of receptions described above (step S204), and prompts the user of the mobile communication terminal 200 to change the designated received character string. Is generated and output (step S205).
FIG. 8 is a diagram illustrating an image represented by the notification data of this example. In the figure, the character string in the underlined portion (1) is the designated received character string specified in step S204, and the character string in the underlined portion (2) is the number of receptions specified in the same step. The character string in the underlined part (3) is the designated received character string acquired in step S201. The user selects the YES button B31 when permitting the change of the designated received character string, and selects the NO button B32 when not permitting the change. When receiving the user's selection, the mobile communication terminal 200 transmits the selection result to the server device 100.

  When acquiring the selection result, control unit 110 determines whether or not the change of the designated received character string is permitted (step S206). When the user permits the change, the control unit 110 invalidates the designated reception character string specified in step S204 and validates the designated reception character string acquired in step S201, thereby enabling effective designation reception. The character string is changed, that is, replaced (step S207).

  On the other hand, when the user does not permit the change, the control unit 110 determines whether or not to cancel the registration of the designated received character string acquired in step S201 (step S208). This determination is performed by causing the mobile communication terminal 200 to display a screen for confirming whether to continue or cancel the registration. When the user cancels registration, the control unit 110 ends the process without validating the designated received character string acquired in step S201.

  Moreover, the control part 110 performs the process of step S204 again, when a user continues registration. However, when the process of step S204 is performed after the process of step S208, the control unit 110 excludes the designated received character string that has been specified as having the smallest number of receptions last time, and has the next smallest number of receptions. Specify the specified received character string. The control unit 110 repeats the same when the process of step S208 is repeated.

As described above, according to this example, the user of the mobile communication terminal 200 can sequentially confirm domain names that have relatively little effect by designation, and can obtain an indication of replacement of the designated received character string. it can.
In this example, the server apparatus 100 executes the operation of invalidating the designated received character string with the smallest number of receptions and validating the new designated received character string without performing notification and confirmation to the user. May be. In this case, the processes of steps S205, S206, and S208 described above can be omitted.

(Operation example 3)
In this example, in addition to the operation of the operation example 2 described above, a designated character string that is not invalid can be set. That is, in this example, a specific designated character string designated by the user is excluded from replacement targets.

  FIG. 9 is a diagram illustrating an image displayed on the mobile communication terminal 200 in this example (or operation example 4 described later). In the figure, a text box T41 is provided for the user to input a designated character string. Radio buttons R41, R42, and R43 are provided to select whether the designated character string input to the text box T41 is a designated received character string, an excluded character string, or a weighted character string. When the user inputs a designated character string and selects the radio button R41, R42 or R43 and then selects the send button B41, the mobile communication terminal 200 selects the designated character string and radio button selected by the user. Are transmitted to the server apparatus 100.

  When receiving the excluded character string, the control unit 110 excludes the character string from the specific target in step S204 regardless of the value of the reception count. That is, in the process shown in FIG. 7, the control unit 110 invalidates the designated received character string having the smallest number of receptions from the designated received character string excluding the designated character string set as the excluded character string. . In this way, the user can reliably receive an e-mail from an e-mail address having a domain name for which registration is not desired to be invalidated.

  The excluded character string may have a finite period for the setting. That is, the excluded character string may be set with a limited period. For example, the control unit 110 can exclude the character string from the specific target in step S204 only for a certain period (such as one month) after receiving the excluded character string. Further, the control unit 110 may accept designation of such a period from the user.

(Operation example 4)
In this example, instead of the number of receptions described above, an evaluation value based on the number of receptions is notified to the user. Such an evaluation value is a value obtained by giving a weight set by the user to the number of receptions. The evaluation value based on the number of receptions is smaller when a weight is given to the number of receptions than when it is not. That is, the weighting for the number of receptions acts to reduce the value of the number of receptions.

Note that the weighting character string can be set without direct designation by the user. For example, when a specified character string is a character string included in an e-mail address stored in the address book of the mobile communication terminal 200 or included in an e-mail address to which an e-mail has been transmitted from the mobile communication terminal 200 If the character string is a character string, a weight may be given to the designated character string. Furthermore, the weighting character string can also have a finite period for setting, similar to the excluded character string.
In the example shown in FIG. 9, the weight is binary, that is, only the state where the weight is given and the state where the weight is not given can be set. However, the weighting in this example may be divided into more stepwise weights.

[Modification]
The present invention is not limited to the implementation according to the above-described embodiment. The present invention can be implemented, for example, according to the following aspects. Further, the present invention may be applied by appropriately combining the following modifications.

(Modification 1)
In the present invention, when character strings are compared by partial matching or backward matching, if there are character string portions common to a plurality of designated character strings, the plurality of designated character strings are combined into one designated character string. It is possible. For example, if the first designated character string is “001.domain.co.jp” and the second designated character string is “002.domain.co.jp”, these are changed to “domain.co. By rewriting the designated character string “.jp”, the number of registrations required for designation can be reduced from two to one. Such a rewriting function is provided as one function of the recording control means. For example, if the specified character string after rewriting is “co.jp” or “jp”, another e-mail address that is not intended by the user may be received. . Therefore, it is desirable that such rewriting is performed under conditions that are given certain restrictions, such as not rewriting the character string of only the top level domain, or setting the number of characters after rewriting to a predetermined value or more.

  In the present invention, if a regular expression or a wild card can be used for comparing character strings, the designated character strings can be collected using these. For example, when the first designated character string is “001.domain.co.jp” and the second designated character string is “002.domain.co.jp”, “*” is a wild card (here Now, let's say that the number of characters that match every character is an indefinite special character.), It is possible to rewrite these into the specified character string "* .domain.co.jp".

(Modification 2)
