Description

  The present invention relates to the technical field of sending and receiving electronic mail. In particular, the present invention relates to the technical field of transmitting electronic mail to a mobile terminal.

  2. Description of the Related Art Conventionally, a mobile phone, which is a typical mobile terminal, has been improved in convenience by being equipped with various functions in addition to the traditional call function using a public wireless line. Among various functions provided in such a cellular phone, an electronic mail (hereinafter abbreviated as “mail”) transmission / reception function is accepted by a wide range of users as an indispensable important function.

  However, in recent years, so-called spam mails that are sent regardless of the intentions of mobile phone users have become a social problem. As a general user's mobile phone usage mode, in order to enjoy the original convenience of the mobile phone to the maximum extent, it is set so that the notification operation by sound, vibration, etc. is performed in real time in response to incoming calls or incoming mail Often to do. For this reason, users who are forced to receive junk e-mails can check whether they are necessary e-mails or junk e-mails by checking the received e-mails every time a notification operation is made to notify them of incoming e-mails. It must be discriminated, and it will be bothersome and angry.

  In order to solve such a problem of spam mail, for example, Patent Document 1 discloses an operation of notifying an incoming mail by recognizing a character string inserted on the sender side in a mail body by a portable terminal on the receiver side. Control techniques have been proposed.

  Patent Document 2 proposes a technique for rewriting a mail header for each mail account.

  Patent Document 3 proposes a technique for prohibiting a mail server from transmitting mail received from a domain designated in advance by a user of the mobile terminal to the mobile terminal.

Japanese Patent Laying-Open No. 2003-318987 (paragraph numbers 0011 and 0013, FIG. 2) Japanese Patent Laying-Open No. 2003-318987 (paragraph numbers 0011 and 0013, FIG. 2) Japanese Patent Laying-Open No. 2004-120428 (paragraph number 0033, FIG. 2)

  However, with the technique described in Patent Document 1, it is not possible to perform a notification operation at the time of mail arrival that accurately reflects the intention of the user on the mail receiving side.

  Further, the technique described in Patent Document 2 is effective as a countermeasure against spam mails for a specific mail account for which the mail header is to be rewritten. However, in general, a person who sends spam mail often changes a mail account that is a sender of the spam mail in a short period of time. For this reason, although it is effective for the set mail account, it is necessary to register each time a junk mail is received from a new mail account, so it becomes a realistic measure because it becomes so-called. I don't get it.

  Moreover, with the technique described in Patent Document 3, not only a specific mail address for sending a spam mail but also all mails belonging to a predetermined domain cannot be received by the mobile terminal. For this reason, the anti-spam measures by specifying the domain may not be able to receive mail from the mail address that belongs to the domain and needs to be received. .

  Therefore, an object of the present invention is to realize a spam mail countermeasure that is practical and convenient for a user while effectively utilizing an existing system configuration.

  In order to achieve the above object, an electronic mail transmission / reception system according to the present invention comprises the following arrangement.

That is, it is determined whether or not at least a part of the information constituting the sender address of the received e-mail matches a pre-registered sorting condition, and the electronic information to which identification information indicating the determination result is given An information processing apparatus (mail server 1) for transmitting mail to the destination address of the electronic mail;
When an e-mail including the destination address is received from the information processing apparatus, when the identification information given to the e-mail indicates that the determination result does not match, a notification operation to the user is performed. A mobile terminal (mobile phone 2) that does not perform the notification operation when it represents a match,
It is characterized by providing.

In a preferred embodiment, the mobile terminal is
When the identification information given to the e-mail received from the information processing apparatus indicates that the determination result matches, the e-mail is stored as a read e-mail so that the user can discriminate it.

In addition, the e-mail transmission / reception device, which is another detection that achieves the same purpose,
It is determined whether or not at least a part of the information constituting the sender address of the received email matches a pre-registered sorting condition, and the email to which identification information indicating the judgment result is given The electronic mail is transmitted to a destination address of the electronic mail.

In addition, the mobile terminal, which is another detection that achieves the same purpose,
At least a part of the information constituting the source address is identification information indicating a determination result as to whether or not a pre-registered distribution condition is met, and the identification information given to the received email is A notification operation to the user is executed when it indicates that the determination result does not match, while the notification operation is not performed when it indicates a match.

  This object is also achieved by a method corresponding to the electronic mail transmission / reception system.

  Also, the same purpose stores a computer program for realizing the operation of an electronic mail transmission / reception device (information processing device) or a portable terminal constituting the electronic mail transmission / reception system by a computer, and the computer program. This is also achieved by a computer-readable storage medium.

  According to the present invention described above, it is possible to realize a spam mail countermeasure that is realistic and convenient for the user while effectively utilizing the existing system configuration.

  That is, in the present invention, when the information processing apparatus (e-mail transmission / reception apparatus) transmits an e-mail received from an external apparatus to a destination address, at least a part of information constituting the source address is registered in advance. It is determined whether or not the distribution conditions are met, and identification information representing the determination result is given. On the other hand, when the mobile terminal receives an e-mail including the destination address, the mobile terminal performs a notification operation to the user when the identification information given to the e-mail indicates that the determination result does not match. Thus, when the match is indicated, the notification operation is not performed. In the present invention, the series of operations is simple in that the transmission / reception of the identification information is added to the system configuration of the existing mail transmission / reception system and the presence / absence of the notification operation is determined according to the identification information received by the mobile terminal. It can be realized by a simple system configuration. In the present invention, the mail addressed to the user (mobile terminal) is discarded (suspended) by the information processing apparatus (e-mail transmission / reception apparatus) regardless of whether or not the pre-registered distribution condition is met. All are sent to the user. Accordingly, it is possible to realize a spam mail countermeasure that is realistic and convenient for the user.

  Hereinafter, the present invention will be described in detail with reference to the drawings by an embodiment in which a mobile phone, which is a typical mobile terminal, is applied to a system configuration in which an e-mail is received from a mail server (mail transmitting / receiving apparatus).

[System configuration]
FIG. 1 is a diagram illustrating an overall configuration of an electronic mail transmission / reception system according to an embodiment of the present invention.

  The electronic mail transmission / reception system shown in FIG. 1 includes a mail server 1, a mobile phone 2, a sorting condition database (DB) 3, the Internet 4, a base station 5, and a personal computer (PC) 6.

  That is, the mail server 1 is an information processing apparatus (mail transmission / reception apparatus) that manages transmission / reception of mail performed between an external device (not shown) and the mobile phone 2 via the Internet 4. The mail server 1 includes hardware such as a CPU (Central Processing Unit) 11, ROM 12, RAM 13, and various software programs executed by the CPU 11.

  Further, the mail server 1 can perform operations such as writing and reading data to the sorting condition DB 3.

  The mobile phone 2 connects to the Internet 4 by performing wireless communication via the base station 5. The cellular phone 2 includes a CPU 21, hardware such as a wireless communication circuit (not shown), and various software programs executed by the CPU 21. The mobile phone 2 has a mail transmission / reception function via the mail server 1 and a website browsing function on the Internet 4 in addition to the call function. In addition, the mobile phone 2 is a general notification unit such as a speaker (including a buzzer) that notifies that a call or mail has arrived, including a buzzer, a vibrator that notifies by vibration, and a lamp that notifies by light emission. As shown).

  The PC 6 is a general computer that can be connected to the Internet 4 by, for example, wired connection. In the present embodiment, the PC 6 is used for browsing websites on the Internet 4. In the present embodiment, the PC 6 is used as an example of a user terminal other than the mobile phone 2 in order to register a distribution condition described later on a Web site provided by the mail server 1.

  Note that the basic system configuration for realizing mail transmission / reception processing performed between the mail server 1 and the mobile phone 2 and the browsing function of the Web site of the mobile phone 2 and the PC 6 itself are currently common technologies. Can be adopted. For this reason, the detailed description in this embodiment is abbreviate | omitted.

[Explanation of mail send / receive operation]
Next, the mail transmission / reception function executed for the countermeasure against spam mail in the system configuration described above will be specifically described.

  In the present embodiment, the user of the mobile phone 2 firstly sends a “sorting condition”, which is information specifying a third party who sends or is expected to send spam mail, via the mail server 1. And registered in the distribution condition DB 3. Here, the third party is information for identifying a specific individual or various groups or aggregates (corporate, nation, etc.) having common attributes. The mail server 1 handles the “sorting condition” registered in the sorting condition DB 3 at this time in a state in which the mail server 1 is associated with information (such as a mail address) that identifies the user. The distribution conditions will be described later with reference to FIG.

  When the mail server 1 receives a mail addressed to the user's mail address (mail account) from an external device via the Internet 4, the mail server 1 refers to the sorting condition DB 3 based on the destination address. Then, the mail server 1 refers to the “sorting condition” registered in the sort condition DB 3 regarding the destination address (the user) of the mail and the information (text code) constituting the sender address of the mail. It is determined whether at least some of them match. Further, the mail server 1 adds identification information representing the determination result in the header of the mail, and transmits the mail with the identification information to the mobile phone 2 corresponding to the destination address.

  When the mobile phone 2 receives the mail with the identification information, if the identification information indicates that it does not match in the above determination, the mobile phone 2 can determine that the mail is not a spam mail. A notification operation is executed. At this time, the mobile phone 2 notifies the user that the mail has arrived by sound, vibration, light emission, or a combination of them appropriately. On the other hand, if the mobile phone 2 indicates that the identification information matches in the above determination, the mobile phone 2 can determine that the mail is a junk mail, and therefore does not perform a notification operation to the user. As a result, the mobile phone 2 does not perform a notification operation to the user even when a mail (that is, a spam mail) that matches a pre-registered sorting condition is received.

<Distribution condition setting process>
Next, as a preparation for realizing the above-described mail transmission / reception operation, a distribution condition setting process provided to a user who uses the mail server 1 will be described.

  FIG. 2 is a flowchart showing distribution condition setting processing executed by the mail server in the present embodiment. This flowchart represents the processing procedure of the software program executed by the CPU 11 in the mail server 1 shown in FIG. In the present embodiment, the distribution condition setting process is provided to a user terminal that desires to register distribution conditions as a service of a website operated by the mail server 1 on the Internet 4.

  In the figure, in response to the user terminal accessing a website of a predetermined URL (Uniform Resource Locater), the CPU 11 transmits information for displaying the condition setting screen (FIG. 3) to the user terminal. (Step S1). Here, the user terminal is the mobile phone 2 or the PC 6. That is, the user of the mobile phone 2 can use not only the mobile phone but also the PC 6 owned by the user at home or the like when setting the distribution conditions.

  FIG. 3 is a diagram illustrating a condition setting screen displayed on the user terminal in accordance with the distribution condition setting process (FIG. 2). The user of the user terminal operates the registration button 203 after inputting necessary information in the forms 201 and 202 while referring to the screen.

  Here, the form 201 is an area for inputting information for specifying junk mail (that is, information for specifying a third party sending out junk mail). Details of information that can be entered in the form 201 will be described later with reference to FIG. The form 202 is an area for inputting an e-mail address for receiving e-mail from the outside by the mobile phone 2 used by the user.

  The mail server 1 registers the information input on the condition setting screen (FIG. 3) in the distribution condition table (FIG. 4) in the distribution condition DB 3 according to the operation of the registration button 203 displayed on the user terminal. (Step S2).

  In the present embodiment, the sort condition that can be registered in the sort condition table (FIG. 4) is information for specifying a third party who sends or is expected to send spam mail. Here, the “third party” is a specific individual or various organizations or collectives (corporates, nations, etc.) having common attributes. And in this embodiment, in order to be able to extract the junk mail which the third party concerned which has transmitted in the mail transmission / reception process (FIG. 5) described later from the mail received from the external device, the above-described condition setting screen ( The information described below can be registered through FIG. In the mail transmission / reception process (FIG. 5) described later, the mail server 1 searches the information registered in the sorting condition table (FIG. 4) for whether it is included in the text code forming the sender address of the received mail. To do.

That is, in the distribution condition table (FIG. 4),
(1) Complete email address
(2) Top level domain (TLD) in the domain name included in the email address: com, jp, etc.
(3) Subdomains in the domain name included in the email address: co, ne, etc.
(4) Host name (user name): Information before (left side) before @
A third party can be arbitrarily specified by each form.

  Here, a more specific example of FIG. 4 will be described. FIG. 4 is a diagram illustrating a distribution condition table registered in the distribution condition DB according to the distribution condition setting process (FIG. 2). In the distribution condition table shown in the figure, for each user of the mobile phone 2 that uses the mail server 1 as a carrier, the user ID (that is, the mail address input in the form 202) and the form 201 are input. It is registered in a state where it is associated with information (sorting conditions).

  That is, the first distribution condition for the user ID “1001” is the case of (3) above, and “AAA.ne.jp” is registered as a specific subdomain including TLD. In this case, it means that the user has defined all mails including a specific domain “AAA.ne.jp” as a sender address as spam mails.

  Further, the second distribution condition for the user ID “1001” and the second distribution condition for the user ID “1008” are in the case of (3) above, and a specific distribution condition including TLD “Co.jp” is registered as a subdomain. In this case, it means that the user has defined all mails sent from a group such as a company, which includes the domain “co.jp” as the sender address, as spam mails.

  Next, the distribution condition for the user ID “1005” is the case of (4) above, and “BBB @” is registered as a specific host name. In this case, it means that the user has defined all mails including the host name (user name) “BBB” in the sender address as spam mails regardless of the domain.

  The distribution condition for the user ID “1007” is the case of (3) above, and “CCC.DDD.co.jp” is registered as a specific subdomain including the TLD. In this case, the user is inconvenienced for a mail including “CCC” as a sub-domain among mails transmitted from a group of companies or the like including the domain “DDD.co.jp” in the source address. It means that it is defined as mail.

  Next, the first sorting condition for the user ID “1008” is the case (2) above, and “com” is registered as a specific TDL. In this case, it means that the user has defined all mails sent from a group such as a company, which includes the top-level domain “com”, as spam mails.

  The first sorting condition for the user ID “1021” is the case (1) above, and a specific third party mail address is registered in a full set. In this case, it means that the user has defined a mail including a specific mail address "EEE@FFF.GGG.ne.jp" as a sender address as a spam mail.

  The second sorting condition for the user ID “1021” is the case (1) above, in which a set of email addresses of a specific third party (in this case, a group such as a company) is registered. Yes. In this case, it means that the user defines, as a junk mail, a mail transmitted from a group such as a specific company “HHH” that includes the top-level domain “com” in the transmission source address.

  When the CPU 11 completes the registration in the distribution condition table in the distribution condition DB 3, the CPU 11 notifies the user terminal of an e-mail indicating that (step S3).

  The distribution conditions are not only individually set by the user of each mobile phone 2 but also set by a mail server 1 administrator (communication personnel, carrier) or the like for a plurality of users at once. May be. In general, a communication person can monitor an email transmission / reception state from a bird's-eye view. It is known that general spam mails are transmitted in large quantities in a short time in a burst manner. Further, in recent years, as a kind of spam mail countermeasure, a communication person may request each user to report the fact together with information specifying the date and time when the user receives the spam mail. Therefore, not only individual users but also communication persons who are managers of the mail server 1 set the distribution conditions flexibly based on the transmission / reception state of the mail being monitored, thereby enabling more effective spam mail. Measures are realized.

  Next, mail transmission / reception processing realized between the mail server 1 and the mobile phone 2 in the situation where the distribution condition registration is completed will be individually described with reference to FIGS.

<Mail server 1>
FIG. 5 is a flowchart showing mail transmission / reception processing executed by the mail server in the present embodiment. This flowchart represents the processing procedure of the software program executed by the CPU 11 in the mail server 1 shown in FIG.

  In the figure, when the CPU 11 receives a mail from an external device via the Internet 4 (in the case of YES determination in step S11), the CPU 11 refers to the sorting condition DB 3 based on the destination address of the received mail (step S11). S12). In step S12, the mail server 1 determines that the distribution condition (domain, mail address, etc.) registered for the destination address (user ID) on the distribution condition table (FIG. 4) is the source address of the received mail. To be included in the text code that forms (the mail server 1 assumes that the destination address and the user ID are associated with each other).

  The CPU 11 determines whether the “read (opened)” setting is necessary or the “unread (unopened)” setting is necessary according to the result of the reference in step S12 (step S13).

  That is, when referring to the distribution condition DB 3 in step S12, if the distribution condition registered for the destination address is included in the text code constituting the transmission source address, the CPU 11 transmits the transmission source address. It is determined that the original received mail is “spam mail”. In this case, the CPU 11 determines that “read” setting is required to give identification information indicating “spam mail” when sending mail to the destination address.

  On the other hand, when the distribution condition registered for the destination address is not included in the text code constituting the transmission source address in the reference to the distribution condition DB 3 in step S12, the CPU 11 transmits the transmission source address. The original received mail is determined to be “not a junk mail”. In this case, the CPU 11 determines that an “unread” setting is required to give identification information indicating “not spam” when sending mail to the destination address.

  If the CPU 11 determines that the “read” setting is necessary (YES determination in step S13), the CPU 11 identifies the “read” setting in the header of the mail to be transmitted to the destination address. Information (read flag) is assigned (step S14). On the other hand, when the CPU 11 determines that the “unread” setting is necessary (in the case of NO determination in step S13), the identification information indicating the “unread” setting is included in the header of the mail to be transmitted to the destination address. (Read flag) is assigned (step S15). Here, an example of the state of the read flag will be described with reference to FIG.

  FIG. 6 is a diagram illustrating a mail header including a read flag set to “read”. In the example shown in the figure, an already-read flag (identification information) 102 “Message-Unread: True” indicating “unread (unopened)” setting is added to the mail header 101 of the mail to be transmitted to the destination address. (The read flag 102 in the case of the “read (opened)” setting is “Message-Unread: False”).

  Next, the CPU 11 transmits the mail to which the read flag 102 is assigned in step S14 or step S15 to the destination address (step S16).

<Mobile phone 2>
FIG. 7 is a flowchart showing mail reception processing executed by the mobile phone in the present embodiment. This flowchart represents the processing procedure of the software program executed by the CPU 21 in the mobile phone 2 shown in FIG.

  In the figure, when the CPU 21 receives mail from the mail server 1 to the terminal via the Internet 4 and the base station 5 (in the case of YES determination in step S21), the read flag in the header 101 of the received mail 102 is analyzed (step S22). That is, when the read flag 102 is “Message-Unread: True”, the CPU 21 determines that the received mail is “not spam” because it is set to “unread”. On the other hand, when the read flag 102 is “Message-Unread: False”, the CPU 21 determines that the received mail is “spam mail” because the received mail is set to “read”.

  Next, the CPU 21 proceeds with the process to step S24 or step S25 according to the analysis result of step S22 (step S23).

  That is, if the determination in step S23 is YES, the read flag 102 is “Message-Unread: True” and the received mail is “not a junk mail”, so it is necessary to notify the user of the incoming mail in real time. is there. Therefore, the CPU 21 notifies that the mail has been received by a ring tone or the like (step S24). On the other hand, in the case of NO determination in step S23, since the read flag 102 is “Message-Unread: False” and the received mail is “spam mail”, announcing the incoming mail will bother the user. Become. Therefore, the CPU 21 advances the process to step S25 without executing the notification operation.

  Then, the CPU 21 stores the received mail in a predetermined area (inbox) of a mail box in which transmitted mail, deleted mail, etc. are stored (step S25). In the inbox of this mailbox, the received individual emails are read (opened) emails and unread (unopened) emails. For example, the display mode of each email title (for example, different symbols, By making the different display colors and different fonts different, the user can easily discriminate them.

  In addition, when the user once confirms the contents of the unread mail stored in the inbox and the mail is already read by the mail server 1, the display mode in the inbox It is good to change. More specifically, the mail that has been read by the mail server 1 is displayed in the inbox in a color that is easy for the user to watch, such as red, or the title display is “Caution for content confirmation!” Guidance should be added. In this case, the CPU 21 may use the read flag 102 “Message-Unread: False” as a criterion for determination in the header 101 of the received mail. According to such a processing configuration, it is possible to prevent the user from erroneously confirming the contents of spam mail (mail that has been opened) including a computer virus (that is, the actual first opening operation).

<Effect of embodiment>
According to the above-described embodiment, the mail to be transmitted to the mobile phone 2 is provided with the already-read flag 102 (identification information indicating whether it is a spam mail) in the mail header 101. Sent to the mobile phone. And according to the setting state of the read flag 102, the cellular phone 2 regulates the notification operation for the junk mail, but performs the notification operation when it is not the junk mail. For this reason, the user does not feel annoyed (that is, feels stress) due to incoming spam mail. Furthermore, the mobile phone 2 makes it easy for the user in the inbox to identify spam mails.

  Moreover, in this embodiment mentioned above, all the mails which should be transmitted to the mobile telephone 2 are transmitted to the said mobile telephone. In this regard, as in the conventional measures against spam mail, mail transmitted from a mail address or domain preset by a user is greatly different from a system configuration in which incoming calls are prohibited for the user's mobile terminal. Therefore, according to the present embodiment, it is possible to eliminate the user's resistance and anxiety in the conventional anti-spam measures that may not be able to receive even mail that needs to be received.

  Further, according to the present embodiment, even a mail determined to be a junk mail by the mail server 1 is stored as a read (opened) mail in the inbox of the mobile phone 2. For this reason, when the user wishes to check the inbox regardless of the ringing tone or the like, if the user wishes, the contents of the spam mail that has already been read are the same as the general mail checking operation. It can also be confirmed by simple operation. Therefore, the mail transmission / reception system according to the present embodiment is excellent in flexibility.

  The above-described excellent effect according to the present embodiment is configured such that the read flag 102 is identified in the mobile phone 2 while the read flag 102 is added to the mail header 101 in the mail server 1. This can be realized with a simple system configuration. Moreover, the man-machine interface (presence / absence of notification operation, ease of discrimination in the inbox) realized by the mobile phone 2 with such a system configuration directly solves the problems of users and communication companies in conventional problems. It is.

  Furthermore, the condition setting in the distribution condition table (FIG. 4), which is a premise for enjoying the above-described excellent effects, is not limited to a specific mail address and domain by a simple registration operation (FIG. 3) by the user. Instead, it can be flexibly set up to a desired subdomain level. Therefore, from this point of view, it is superior in convenience compared with a uniform conventional spam mail countermeasure such as registration of a mail address or domain.

  That is, according to the mail transmission / reception system according to the present embodiment, it is possible to realize a realistic and convenient spam mail countermeasure that is simple setting operation for the user while effectively utilizing the existing system configuration. .

  In the above-described embodiment, for convenience of explanation, the name of the identification information indicating whether or not it is a spam mail is the name “read flag”, and the actual status is “Message-Unread: True”, A text code “Message-Unread: False” (that is, code information forming a character string) is used. However, such a configuration is merely an example, and the name of identification information and the actual state of information to be communicated may be selected as appropriate.

  In the above-described embodiment, the system configuration in which the read flag 102 that is identification information is added to the mail header 101 has been described as an example. However, the present invention is not limited to such a system configuration, and may be added to a place other than the mail header.

  The present invention described by taking the above-described embodiments as examples can realize the functions of the flowcharts (FIGS. 2, 5, and 7) referred to in the description for the mail server 1 and the mobile phone 2 described above. After the computer program is supplied, the computer program is read out and executed by the CPU (11, 21) of the apparatus. Further, the computer program supplied to the apparatus may be stored in a readable / writable memory or a storage device such as a hard disk device.

  The computer program group executed by the mail server 1 is not limited to the system configuration executed on a single computer. That is, the computer program group may be organically executed in an environment appropriately distributed over a plurality of computers scattered on the communication line.

  The program code executed in each device may be provided in a state stored in a storage medium, or may be transmitted via a transmission medium.
