Description

  The present invention relates to a mail address generation system, a mail address generation method, and a mail address generation program, and in particular, when posting information to be displayed on a video display device by electronic mail in a system in which a video display device and a portable terminal are linked. The present invention relates to a method for preventing the erroneous posting and a system configuration for realizing the method.

  Conventionally, people who cannot participate in various events such as weddings and funerals have sent messages in the form of telegrams such as congratulatory telegraphs and souvenirs. However, there is a problem that sending such a telegram is time-consuming and expensive. In view of this, a system has been proposed in which various displays such as an electric bulletin board and a screen are installed at an event venue such as a wedding hall to display a message of a person who has failed or a visitor's message (see Patent Document 1).

  In recent years, as one form of such a system, a high-definition display is installed in a public place and used as an electronic poster. In addition, a system has been proposed in which a printer is installed at an event venue and a message associated with the event is printed (see Patent Document 2). In this system, messages are stored in a server, and transmission date / time information generated from event designation information is added to the messages and stored. The server transmits a message to a computer connected to the printer installed at the event site according to the transmission date and time information. By operating in this way, a message corresponding to the event can be automatically output at the venue.

  On the other hand, from the viewpoint of message censorship, in a WEB page that publishes event information and the like, a system has been proposed in which event information stored on a server is always censored by a censor department and then published to the WEB page (Patent Literature). 3).

  Further, in these conventional systems, when posting information using e-mail or the like, for example, there is a case where information is transmitted with a wrong mail posting destination. As a countermeasure against this problem, for example, among the destinations managed by the system, a destination close to the erroneous transmission address is notified to the erroneous transmission user, or if it is clearly known that the error is detected, it is converted into correct address information. A processing method has been proposed (see Patent Document 4).

Also, if it is necessary to generate a unique address for each posting destination on the system side, a hash value is generated from the email address of the Internet facsimile user using the hash function and used as a proxy address. A method of performing the above has also been proposed (see Patent Document 5).

  In the above prior art, when a system manages a plurality of events and automatically generates an e-mail address for posting a message for each event, it is usually generated using a date and user name related to the event. However, for example, when the event is generated using a date, if the events are concentrated during a certain period, the value of the generated post address is hardly changed, and the user sends a mail to the system by mistakenly posting the post address. The situation is likely to occur. In such a case, the system may receive a message of a different event without processing it as an address miss.

  In addition, when an e-mail address is generated using a user name, when there is another user with the same name, there is usually a measure to add a number after the name. There is a case where an input error is invited to the user side. Furthermore, although it is considered that the alphabet is often used as an e-mail address derived from the user name, when the user uses the mobile terminal as an e-mail transmission device, an address input operation caused by a key-in operation specific to the mobile terminal There is a concern that it itself becomes complicated.

  Furthermore, in the above prior art, when hash values are used for mail address generation, even if the user names are different, if the generated hash values are the same, the specification is often rejected. Inconvenience may occur at the time of user registration, such as forcing a user who wants to register his / her name as a user name multiple times.

  Further, in the above conventional technique, since the difference between the newly generated hash value and the existing hash value is not compared except that the values are different, even when the values are close to each other, it is allowed. For this reason, when such a very similar value is used as an e-mail address (a part thereof), erroneous posting due to a mistake in the user's e-mail address is likely to occur.

  Accordingly, the present invention has been made in view of the above problems, and mainly aims to suppress erroneous posting of a message due to a mail address designation mistake of a poster and to generate a mail address that can be easily input by the poster. Objective.

  An e-mail address generation system of the present invention that solves the above problem is an e-mail address generation system that generates an e-mail address for each event, a storage unit that stores a hash function, and event information uniquely defined for each event.

--- Processing flow example 1 ---
Hereinafter, the actual procedure of the mail address generation method in the present embodiment will be described with reference to the drawings. Various operations corresponding to the e-mail address generation method described below are realized by the program 12 that the system 10 reads into the memory 13 and executes. And this program 12 is comprised from the code | cord | chord for performing various operation | movement demonstrated below.

  FIG. 5 is a flowchart showing a series of processing flow when the event requesting user 150 applies for an event to the event execution company 110. Here, when the event requesting user 150 and the message management user 120 are different, the event requesting user 150 checks the message management user 120 in advance with a mail address necessary as a post confirmation mail transmission destination ( Step 600). This post confirmation mail is transmitted from the system 10 to the PC 121 and the mobile phone 122 of the message management user 120 in accordance with the prior confirmation of the post message (for example, confirmation of the content that can be displayed on the display device 115). Email.

  Further, the event requesting user 150 visits the event execution company 110, makes a meeting about the event, and requests the event to be held (Step 601). On the other hand, the event execution company 110 collects event information (see FIG. 2: event information 202) based on the result of the meeting. Then, a registration request instruction including the event information is transmitted to the system 10 via the Internet 165 from the PC 113 of the event execution company 110, for example. With this process, the event execution company 110 requests the event service providing company 100 to register the event information in the event management information database 109 of the system 10 (Step 602).

  The system 10 in the event service providing company 100 stores the event information received from the PC 113 of the event execution company 110 in the storage device 108 (Step 603). The system 10 generates various information based on the stored event information. The information generated at this time includes, for example, setting information for the USB memory 119 (eg, setting information of the display device 115 regarding the output form of the posted message) (Step 604).

  Subsequently, the system 10 executes a process for generating an event-specific posting mail address generated for each event by the mail address generation method of the present invention, and generates a posting destination account 206 in the event management information database 109 (Step 605). . Details of this processing will be described later. When appropriate information generation is thus completed, the system 10 writes, for example, the generated setting information and information necessary for starting the display device 115 to the USB memory 119 (Step 606).

  The USB memory 109 is delivered to the event execution company 110 together with other information to be notified (for example, an email address including the posting destination account 206) (Step 607). Upon receiving this, the event execution company 110 notifies the event requesting user 150 of event information required by the message posting user 130 (for example, the address of the message posting destination) (Step 608). This notification can be executed by data communication from the PC 113 of the event execution company 110 to an appropriate terminal device included in the event requesting user 150.

  On the other hand, the event requesting user 150 that has received the notification of the event information describes the message posting destination address in a wedding invitation, for example, and notifies the message posting user 130 (acquaintance, etc.) (Step 609).

--- Processing flow example 2 ---
FIG. 6 is a flowchart showing a detailed example of the process for generating the post mail address for each event described above. Here, Step 605 shown in the flowchart of FIG. 5, that is, processing for generating an event-specific posting mail address will be described. After the event information is registered in the event management information database 109 in the storage device 108, for example, the Web server 106 among the server machines 104 of the system 10 is necessary for generating the posting destination account 206 (see FIG. 2). Information about the event is retrieved from the event management information database 109 and acquired (Step 700). The event information acquired at this time preferably includes the date and time of the event and information for identifying the user (for example, either the bride and groom name or the management screen access information). However, information for identifying the user is not essential. When the character string of the event information acquired here is shorter than a predetermined standard for generating a hash value, the Web server 106 manages other information other than the event date and time and the information for identifying the user as event management. Extracted from the corresponding event information in the information database 109 and acquired.

  The Web server 106 concatenates the event information acquired here as a character string to create a generated character string (Step 701). In the example of FIG. 6, the event information is “date: yyy / mm / dd”, “location: park front”, “other information: sample”, and the generated character string is “yyymmdd park front sample”. ing.

  The Web server 106 inputs the character string generated in this way to the Hash function and generates a Hash value (Step 702). There is no particular limitation on the Hash function used at this time, but it is desirable to use one having high collision resistance. Collision resistance refers to the property that the hash value changes greatly if the original data is different even by one bit, and the same hash value is unlikely to be generated from different data. Note that it is naturally possible to use a proof hash function such as MD5 or SHA-1, which is normally used when executing the hash value generation process.

  Subsequently, the Web server 106 cuts out a character string for n characters from the first m-th character from the generated hash value. The extracted character string is a candidate for the posting destination account 206, and an e-mail address (for example, “133343567@xxxx.co.jp” including the candidate for the posting destination account 206 is generated (as a candidate for an event-specific posting address). (Step 703) The e-mail address is a candidate for the posting destination account 206 (a character string before the at sign), and the part after the at mark is the predetermined provider name, the domain name of the event execution company 110, the country / region Can consist of code.

  Normally, the character string segmentation process is performed with “m” = 0. In addition, “n” as the number of characters to be cut out can be set according to the size of the event, for example. This is because as the event scale increases, the number of message posting users 130 is expected to increase accordingly. In the example of FIG. 6, the hash value is “133435675334”, and the candidate for the posting destination account 206 generated by cutting out is “133435567” under the conditions of “m = 0, n = 8”.

  The Web server 106 performs collation with the posting destination account already registered in the event management information database 109 (part of the registered mail address) for the posting destination account 206 generated in this way (Step 704). Then, the Web server 106 checks whether the difference between the character strings of the candidate for the posting destination account 206 and the other registered posting destination accounts is equal to or more than a predetermined number of p characters (Step 705).

  Here, it can be seen that the larger the predetermined number of characters “p”, the lower the probability of erroneous message posting due to an input error of the message posting user 130. Therefore, it can be assumed that the predetermined number of characters “p” is determined according to the system configuration and the event scale. Alternatively, for example, the Web server 106 accumulates a log of erroneous postings in a predetermined storage device, and counts the number of erroneous postings every predetermined period. When the number of erroneous postings is greater than a predetermined number, the “p” It is also possible to make a setting such as increasing the “p” and decreasing the “p” when it is smaller.

  As a result of such collation, if the Web server 106 has a candidate for the posting destination account 206 and a registered posting destination account 206 in which the difference in the character string is not more than p characters (Step 705: No), the “m” The values of “n” are changed (Step 706), and Step 703 is executed again. At this time, without changing “n”, the Web server 106 executes processing such as increasing the value of “m” to +1, that is, increasing the number of characters to be cut from the hash value.

  In this way, candidates for posting destination accounts 206 that differ from all posting destination accounts 206 registered in the event management information database 109 by p characters or more can be generated as posting destination accounts 206 corresponding to the event (Step 707). That is, the Web server 106 generates the mail address including the posting destination account 206 generated in this manner as the event-specific posting mail address. Note that the server that performs the mail address generation process is not necessarily the Web server 106, and may be another server.

FIG. 7 is a flowchart showing a flow when the message posting user 130 posts a message. In this flow, the message posting user 130 prepares a posting message using the PC 131, the mobile phone 132, etc. (Step 800). As an example of a posted message prepared by this work, for example, an email (a posted message is described) attached with a photograph taken with a camera-equipped mobile phone can be considered.

  The posted message is generated by the above-described processing, and the posting mail address for each event that has already been notified to the message posting user 130 is used as the transmission destination. It is transmitted to the mail server 105 (Step 801). The mail server 105 receives the posted message transmitted from the PC 131, the mobile phone 132, etc., and registers it in the posted message information database 160. At this time, the mail server 105 performs the registration process using the sender mail address of the message posting user 130 as a key. Thereby, the mail server 105 that has received the posted message overwrites the data of the posted message with the latest posted message when the message posting user 130 has already posted to the same event-specific posting email address. It can be updated (Step 802).

  Then, the mail server 105 transmits a reply message 900 to the source mail address in order to indicate to the message management user 130 that the post message has been received (Step 803).

  An example of this reply message 900 is shown below. FIG. 8 shows an example of the configuration of the reply message 900. In this reply message 900, for example, the name 906 of the event requesting user 150 is displayed in the title 905, and a message registered in advance as a thank you message 901 is displayed. The message posting user 130 can determine whether posting has been made to the correct posting destination by looking at the reply message 900. In addition, it is considered that the event requesting user 150 may attach a photograph image 904 or the like with a meaning of thanks to the message posting user 130. This is also transmitted in advance registered in the system 10.

  The PC 131 or the mobile phone 132 of the message posting user 130 that has received the reply message 900 displays the title and text of the reply message 900 on a display or the like. The message posting user 130 viewing this can determine whether or not his / her posting destination is correct, that is, whether or not a message has been posted regarding a desired event (Step 804). If the posting destination is wrong (Step 804: Yes), the message posting user 130 clicks the posting destination change URL 903 described in the reply message 900. The PC 131, the mobile phone 132, or the like that has received the click accesses the Web server 106 according to the posting destination change URL 903 (Step 805).

  Then, the Web server 106 returns a posting destination change Web page 1000 to the PC 131, the mobile phone 132, or the like. The posting destination change Web page 1000 is displayed on the PC 131, the mobile phone 132, or the like (Step 806). The message posting user 130 inputs a correct posting destination account (or all or part of the event-specific posting mail address including the posting destination account) on the posting destination change Web page 1000, and the PC 131, the mobile phone 132, etc. The input is accepted (Step 807).

  The post destination change Web page 1000 will be described below. FIG. 9 is an example of the posting destination change Web page 1000. In this Web page 1000, since the domain name after the @ (at sign) is uniquely determined once the system 10 is determined, only a posting destination account can receive an input in the input box 1001. If there is no problem even if the message posting user 130 can easily find another address, a list of other event posting destination accounts 206 having a character string close to the wrong posting destination account is obtained from the event management information database 109. A format is also conceivable in which it is extracted, displayed on this Web page 1000, and a candidate selection is accepted from the extracted page.

  Subsequent to Step 807, the Web server 106 executes an event search in the event management information database 109 based on the posting destination account input on the Web page 1000, so that the event to be registered in the posted message is performed. And the event to be registered in the posted message is changed (Step 808). Further, the Web server 106 transmits a reply message 900 corresponding to the registration change destination event to the PC 131, the mobile phone 132, or the like (Step 809).

  On the other hand, the PC 131, the mobile phone 132, and the like can accept a click instruction for the deletion URL 903 described in the reply message 900 in response to a request to delete the posted message even if the posting destination is correct (Step 810: Yes). , Step 811). The PC 131, the mobile phone 132, and the like notify the Web server 106 of an instruction to delete the posted message. Upon receiving this notification, the Web server 106 deletes the corresponding posted message, for example, in the posted message information database 160 (Step 812), transmits a deletion completion screen to the PC 131, the mobile phone 132, etc. (Step 813), and performs processing. finish.

--- Processing flow example 4 ---
FIG. 10 is a flowchart showing a flow when the message management user 120 checks a message posted by the message posting user 130. In this case, it is assumed that a posted message is posted to the mail server 105 of the system 10 from the PC 131 or the mobile phone 132 of the message posting user 130 (Step 1100).

  Upon receiving this post message, the mail server 105 transmits a post notification message 1200 to the PC 121 or the mobile phone 122 of the message management user 120 (Step 1101). FIG. 11 is an example of the aforementioned post notification message 1200. The posting notification message 1200 includes, for example, a mail body including a message part 1201 of posted contents, a URL 1202 for a check site, a URL for a posting permission instruction site, and an attached file 1204.

  The posting contents can be confirmed by the message management user 120 viewing such a posting notification message 1200 (Step 1102). When the posting of the posting message is permitted (Step 1103: Yes), the message management user 120 clicks the posting permission URL 1203 in the posting notification message 1200. The PC 121, the mobile phone 122, etc. accept this click and send it to the Web server 106 (Step 1104). On the other hand, the Web server 106 that has received this notification permits the posting of the designated posting content (Step 1105).

  For example, it can be assumed that the posting described here means that the Web server 106 accepts browsing of posted messages from other devices on the Internet 165. Further, when the posting is permitted, it can be assumed that the Web server 106 sets “permitted” data in the item of the posting permission / inhibition 307 in the posting notification message information database 160.

  The web server 106 that has performed the posting permission process displays a posting completion screen on the PC 121 or the mobile phone 122 of the message management user 120 (Step 1106). On the other hand, when displaying the management Web screen 1300 (Step 1107: Yes), the message management user 120 clicks the management Web screen display URL 1202 in the posting notification message 1200. The PC 121, the mobile phone 122, etc. that have received this click transmit the click event to the Web server 106 (Step 1108).

  On the other hand, the Web server 106 that has received the click event generates a screen that can be accessed by the corresponding message management user 120 user based on information embedded in the management Web screen display URL 1202, for example. The data is transmitted to the PC 121, the mobile phone 122, etc. (Step 1109). The message management user 120 can perform various operations on the posted content on this screen 1300.

  FIG. 12 is an example of the management Web screen 1300 described above. The name 1301 of the event requesting user 150 is displayed at the top of the management Web screen 1300 so that it can be seen who the wedding is. Posted messages are displayed as a list for illustration. As information about each posted message, posted image 1302, sender mail address 1303 of the poster, current posting state 1304, message content 1305, posting permission / prohibition setting radio button area 1306, execution to execute execution of the selected setting The button 1307 includes a reset button 1308 for instructing resetting of settings. The management Web screen 1300 is assumed to be a display screen on a PC (personal computer). However, it is possible to simplify the display portion of the screen by omitting a decoration portion, and to configure a display screen for a mobile phone. It is.

FIG. 13 is a flowchart showing a flow when the event execution company 110 activates the display device 115. It is assumed that the USB memory 119 previously sent from the event service provider 100 is set in the USB memory reader 118 of the display device 115 (Step 1400). The activated display device 115 (Step 1401) reads the USB memory 119 and reads the setting information of the display device 115 (Step 1401). The display device 115 is connected to the back-end server 107 via the Internet 165 and notifies the back-end server 107 that it has started by notifying the read setting information (Step 1402).

  Receiving this notification, the back-end server 107 authenticates the notified setting information (Step 1403). The back-end server 107 confirms that the display device 115 is a predetermined valid display device by this authentication process. The back-end server 107 transmits a list of information to be displayed on the display device 115 (stored information in the event management information database 109 and the posted message information database 160) to the corresponding display device 115 (Step 1404). Upon receiving the information list, the display device 115 that receives the information starts displaying the corresponding information (Step 1405). This display can be performed according to the designation of the output form of the posted message included in the setting information stored in the USB memory 119.

  FIG. 14 is a diagram illustrating a screen example 1 displayed on the display device 115. In the screen display example 500, a plurality of message boxes 504 each including a posted image 505 and a posted message 506 are displayed. The message box 504 is moved and displayed along the movement paths 508 and 509, for example. The title area 501 displays the bride and groom names. In the date area 502, the date of the event is displayed. In the venue name area 503, the name of the event venue is displayed. The message box 504 corresponds to one post, and a post image 505 and a post message 506 are displayed together with the message management number 507.

  On the other hand, FIG. 15 is a diagram showing a screen example 2 displayed on the display device 115. This screen display example 510 is a form in which posted messages are displayed as a list. In the screen display example 510 here, posted messages 520 for the groom and the bride are displayed symmetrically. Title areas 511 and 512 display the names of the bride and groom. In message list areas 513 and 514, posted messages 520 of acquaintances of the bride and groom are displayed in a list. In the message number display areas 515 and 516, the total number of posted messages is displayed. One of the screen display example 500 and the screen display example 510 may be adopted. When a plurality of display devices 115 are installed, the screen displays 500 and 510 are simultaneously displayed on separate display devices 1115. It may be displayed.

FIG. 16 is a flowchart showing an example of processing when a new post message arrives while the display device 115 is operating. Here, it is assumed that a posted message from the message posting user 130 is transmitted from the PC 131, the mobile phone 132, or the like to the mail server 105 in advance (Step 1500). Then, the mail server 105 receives this posted message, and thereafter, the posted content check by the message management user 120 is executed by the PC 121, the mobile phone 122, etc. in the procedure already described with reference to FIG. 10 (Step 1501).

  The Web server 106 that has received the check result of the posted content determines whether an event corresponding to the posted message is being held, for example, based on the data of the status 207 in the event management information database 109 (Step 1502). Here, if the event is being held (Step 1502: Yes), the posted message is transmitted to the corresponding display device 115 (Step 1503). The display device 115 that has received the posted message displays it as a new arrival message (Step 1504).

--- Processing flow example 7 ---
FIG. 17 is a flowchart showing a processing flow for deleting a specific message displayed on the display device 115 during system startup. In this case, it is assumed that the PC 121 or the mobile phone 122 of the message management user 120 accesses the management Web screen 1300 (Step 1600). Then, the Web server 106 accepts the posting prohibition setting of the post message desired by the message management user and executes the processing (Step 1601). Based on this setting, the Web server 106 changes the state of the target posted message (eg, posting permission / prohibition 307 of the posted message information database 160) (Step 1602). The back-end server 107 that has detected this checks whether an event related to the posted message is being held, that is, whether the related display device 115 is operating, for example, by communicating with the display device 1115 (Step 1603). If the corresponding display device 115 is operating (Step 1603: Yes), the back-end server 107 issues a message deletion notification to the display device 115 (Step 1604). Upon receiving this notification, the display device 115 deletes the posted message currently being displayed and corresponding to the deletion notification (Step 1605).

FIG. 18 is a flowchart showing the processing flow after the end of the event. When the event ends, the event execution company 110 stops the operation of the display device 115 (Step 1700), and removes the USB memory 119 from this (Step 1701). The USB memory 119 is returned to the event service providing company 100 (Step 1702). The event service provider 100 that has received the returned USB memory 119 performs event end setting (Step 1703). Note that the event end setting process may be automatically executed by the server 104 that refers to the information on the event schedule by defining the event schedule information for each event in an appropriate storage device.

  It may be preferable to provide the event requesting user 150 with information related to the finished event (eg, a posted message received from an acquaintance, etc.) as one of good memories. Therefore, the server machine 104 writes a list of posted messages to the CD-ROM 40 (recording medium) via the CD-ROM drive 102 (Step 1704). As a method for realizing this processing, for example, the server machine 104 creates a posted message list and an HTML file (reading program) that reads and displays the posted message list, and writes this in the CD-ROM 40.

  When the event requesting user 150 browses the recorded contents of the CD-ROM 40, a method of displaying the HTML file with a browser is conceivable. The CD-ROM 40 thus created by the server machine 104 is sent from the event service providing company 100 to the event implementing company 110 (Step 1705). The event execution company 110 sends the CD-ROM 40 to the event requesting user 150 (Step 1706).

FIG. 19 is a flowchart showing a flow in which the event requesting user 150 creates and sends a thank-you email to the message posting user 130 after browsing the recorded information on the CD-ROM 40. FIG. 20 is a diagram showing an example of a menu screen configuration in the message writing CD-ROM of this embodiment.

  When the event requesting user 150 views the CD-ROM 40 with an appropriate terminal, a menu screen 1900 is displayed on the display (Step 1800). This screen 1900 is preferably in a format that can be browsed by a general Web browser such as an HTML file. When “Send Thanks Mail to Contributor” 1903 is selected from the menu, the Web browser displays a thank you mail input form 2000 (mail reply program) (see FIG. 21). It is considered that the form itself is preferably written in the CD-ROM 40 and the terminal of the event requesting user 150 is connected to the Web server 106 when the send button 2004 is pressed.

  When the event requesting user 150 inputs all desired information on the form 2000 and then clicks the send button 2004, the event requesting user 150 sends the form 2000 from the terminal of the event requesting user 150 to the Web server 106 of the event service providing company 100. , That is, a thank you mail message (reply message) is sent (Step 1802). Thereafter, the mail server 105 extracts a list of contributors to be transmitted in the post message information database 160 (Step 1803), and sends a thank-you message to the contributor E-Mail 306, which is the sender mail address of each contributor. Transmit (Step 1804).

  According to the present invention, when using a message display system, even if events are concentrated in a specific period and many similar user names are registered, the values of the message posting e-mail addresses for each event are Even if you make a little mistake, you can make it different enough that the message is not posted incorrectly in other events. In addition, since it is possible to provide an e-mail address that can be easily entered on a mobile terminal, it is possible to prevent the posting error of the poster of the message to the event, and to reduce the trouble of inputting the e-mail address.
