BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of mutual communication with a user terminal such as a mobile phone via the Internet or the like and manages data transmitted from the user terminal. The present invention relates to a method, a data management system program, and a data management system recording medium.

2. Description of the Related Art Conventionally, in order to collect quizzes and questionnaires with prizes on TV and radio and to collect responses from viewers via the Internet, a response HP (Home Pag.
e) was open. Also, the URL of this response HP (Uni
In order to notify the viewer of the form resource locators), the URL of the response HP has been made public in television broadcasting and radio broadcasting. However, even if the viewer who has accessed the published URL makes a response such as a questionnaire on the response HP, the HP founder cannot recognize who accessed the URL. for that reason,
It was not possible to know whether the viewer was really watching the TV program or listening to the radio program, which could lead to spoofed responses.

Therefore, conventionally, in order to identify (authenticate) the viewer, responses from the viewer have been collected by the method shown in FIG. Note that FIG. 6 shows a user terminal (mobile phone) 1 using the system (server computer) 101.
5 is a sequence diagram showing a data management method for managing various data transmitted from 05 via a communication network (a mobile phone network and the Internet). FIG. In addition, a website is opened in the system 101, and
On the b site, an HP for authentication for obtaining the user's e-mail address to identify (authenticate) the user, and registration data such as questionnaire responses from the user are collected and registered as data about the user. HP for registration to do is included. Further, the system 101 includes the authentication H
A data management DB 111 for managing the user's electronic mail address obtained by P and the registration data from the user collected by the registration HP in association with each other is constructed.

First, a user (viewer) who has recognized the URL of the authentication HP published by a television program or the like accesses the Internet from the user terminal 105 (step S101). Then, the published URL is input to the user terminal 105, and HTTP (Hypertext Transfer Prot.
access to the authentication HP of the system 101 (step S102). This allows the system 10
In 1, access is accepted (step S103).
Then, the system 101 transmits the authentication HP data to the user terminal 105 based on HTTP (step S
104). The HP data for authentication also includes data indicating an authentication button linked to the destination (system 101) of an empty mail described later. The destination address of this empty mail is set in advance on the system 101 side and is an address common to all users. Also, the authentication button is a button that is composed of a character string (including numbers and symbols) that prompts the user to send an electronic mail, and can execute a so-called Mail to link function when clicked by the user. With this Mail to link function, when the user clicks the authentication button, the default mailer (Mailer) on the user terminal 105 is activated, and the user terminal 1
05 is a function of displaying a new electronic mail creation screen with the system 101 as the destination.

Next, an HP image for authentication including an authentication button is displayed on the display of the user terminal 105 (step S105). Then, when the user clicks the authentication button, the mailer is activated (step S106). When the mailer is activated, a new e-mail creation screen with the system 101 as the destination is displayed.

[0006] Next, the user clicks the send button on the e-mail creation screen without inputting any characters (including numbers and symbols) (leaves blank), and the SM is clicked.
An empty mail is transmitted to the system 101 side based on TP (Simple Mail Transfer Protocol) (step S10).
7). Then, the user disconnects the user terminal 105 from the Internet once (step S108). The reason for disconnecting from the Internet will be described later.

Next, the empty mail transmitted in step S107 is once sent to the mobile mail server computer of the telecommunications carrier, and then the system 101
(Step S109). As a result, the system 101 receives the empty mail (step S11).
0). In addition, in the mobile mail server computer, in order to eliminate mischief / junk / direct mail, a service for checking e-mail is implemented. However, this is only when the sender is the server computer. If the sender is a mobile phone, the e-mail is not checked. Therefore, in step S109, the electronic mail (empty mail) is sent to the system 101 without being checked.

Next, the system 101 manages the electronic mail address of the individual user (sender) attached to the received empty mail in the data management DB (Data Base) 111 (step S111). As a result, the user can be identified (authenticated), and a response due to a certain impersonation can be prevented.

Next, the system 101 sets the destination to the user terminal (source) 105 and transmits a notification mail for notifying the URL of the registration HP based on SMTP (step S112). This notification e-mail contains the registration H
Data indicating the URL of P is included. This registration H
The description part of the URL of P is linked to the URL of the registration HP, and the user can access the URL of the registration HP by clicking the description part of the registration HP URL.

Next, the transmitted notification mail is once sent to the mobile mail server computer of the telecommunications carrier. In this case, since the transmission source is the server computer (system 101), it is checked whether it is mischief / junk / direct mail, and then it is transmitted to the user terminal 105 (step S113). As a result, the system 101 receives the registration HP notification mail (step S114).

Next, the user who notices that he has received the registration HP notification mail connects the user terminal 105 to the Internet again (step S115). In this way, disconnecting from the Internet and reconnecting to the Internet is the amount of traffic (Traffi) based on SMTP.
Since c) is overwhelmingly smaller than the amount of communication based on HTTP, it takes a long time for the data to reach the destination,
Moreover, when sending an electronic mail from the system 101 based on the SMTP, as shown in step S113, more time is required for checking whether it is a mischief / junk / direct mail by a telecommunications carrier or the like. This is because the user has to wait several minutes to several hours from the time the empty mail is sent in step S107 to the time when the notification mail is received in step S114.

It should be noted that in steps S112 and S113 described above, waiting time may be reduced if the registration HP data is transmitted based on HTTP without sending the registration HP notification mail on purpose based on SMTP. To be However, if the user is not browsing the authentication HP just by asking the destination address of the empty mail from another person, or if the destination address of the empty mail is acquired from the system 101, the connection to the Internet is disconnected and the authentication HP It is possible that you are not browsing. In this way, the HP for authentication
Even though you are not browsing the
User data for registration HP data for switching to P
Sending it to 05 is just a waste. Therefore, as shown in steps S116 and S117 below,
The registration HP data is sent to the user terminal 10 only after positive access from the user to the registration HP is accepted.
It will not be sent to 5. Therefore, in order to encourage this user to actively access, the notification HP of the registration HP must be transmitted to the user terminal 105 in step S112.

[0013] Next, the user is notified of the registration H
The user clicks the description part of the URL of P to actively access the registration HP of the system 101 based on HTTP (step S116). This allows the system 10
In 1, the access is accepted (step S117).

Next, the system 101 transmits registration HP data to the user terminal 105 based on HTTP (step S118). As a result, the user terminal 105
The registration HP image is displayed on the display (step S119). On the registration HP image, a screen for notifying the completion of the identification (authentication) in step S111 and prompting the user to input registration data is displayed. Therefore, the user inputs registration data such as his / her name, sex, and answer to the questionnaire, and the system 101 is used based on HTTP.
(Step S120). As a result, the system 101 receives the registration data (step S12).
1), managing in the data management DB 111 (step S1)
22).

As described above, in the conventional data management method, as shown in step S102, direct access from the user to the registration HP is avoided, and step S10 is performed.
As shown in 4 to S115, by causing the user to send an empty mail, the user is specified (authenticated) from the electronic mail address of the user transmitted accompanying the empty mail. Then, after the user is specified (authenticated), by accessing the registration HP as shown in step S116, the answers can be collected in a state in which the respondents (users) such as the questionnaire are specified.

As a user, it takes time and effort to send a blank mail in order to be identified (authenticated), but since this blank mail only needs to be sent without inputting any characters, the user can be sent. It is possible to minimize the time and effort involved.

[0017]

However, in the conventional data management method, a long waiting time required to disconnect from the Internet is required as in step S108, and therefore, for example, in the case of radio / TV programs. If the registration data must be transmitted to the system 101 within a short period of time, such as when an answer to a quiz or questionnaire (registration data) must be answered during program broadcasting, the registration data cannot be transmitted in time. There was a problem. In particular, although programs for conducting quizzes and questionnaires are often broadcast during so-called golden time (7:00 pm to 9:00 pm), this time zone is used by people who come home from the company or school or who are on their way home. Since emails are sent and received frequently, the telecommunications carrier's mobile mail server is overcrowded and the waiting time becomes long, and there is a high possibility that quizzes and questionnaires cannot be answered. It was

Further, from the system 101 to the user terminal 10
Since it is necessary to send the notification email of the registration HP to No. 5, there was a concern that the notification email might be hacked by a hacker while the notification email was being sent. Therefore, there is a possibility that the website is illegally accessed by using the notification email hacked by the hacker, and an illegal act such as sending incorrect registration data to the system 101 side is performed.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and even when the registration data is managed after the user is specified (authenticated) by sending a blank mail to the user. The object of the present invention is to provide a user with good operability of the user terminal and prevent hacking.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a communication infrastructure for managing various data transmitted from a user terminal 5 via a communication network using a data management system (hereinafter referred to as “system”) 1 according to this embodiment. Structure (Infra
structure) is shown.

As shown in FIG. 1, the system 1 is installed in a data management center (A), and the system 1 is composed of one server computer. Further, FIG. 1 shows a state in which the system 1 is capable of mutual communication with the user terminal 5 of the user (B) via the communication network including the Internet 2, the mobile phone network 3, and the nearest base station 4. 1 shows a state in which the system 1 can intercommunicate with a computer (not shown) of a broadcasting station (Hei) via a communication network composed of the Internet 2.

Of these, the data management center (A) is a so-called ASP (Application Service Provider),
For example, it is operated by the applicant. The data management center (A) manages data such as questionnaires and quizzes about TV programs provided by the broadcasting station (H) via the communication network under the contract with the broadcasting station (H) and the user (B). Collect and analyze the answers, such as questionnaires and quizzes, presented to, and provide the analysis results to the broadcasting station (丙), and receive the consideration for the collection and analysis from the broadcasting station (丙).

The user (B) is a viewer of a radio program or a television program, and in the present embodiment, the broadcasting station (H)
Is a person who is watching a television program broadcast by the television 6 at home. The user terminal 5 in this embodiment is a mobile phone, a PHS (Personal Handy-phone System) phone,
PC (Personal Computer), PDA (Personal Computer)
Digital Assistant: a portable information terminal), a remote controller of a digital television capable of bidirectional communication by data broadcasting, and the like, but in the present embodiment, a case of a mobile phone will be described.

The system 1 also stores a program (p) for executing the steps (S3 to S6, S11 to S15, S18, S19) described later.

Further, a website is established in the system 1, and for this website, for authentication for obtaining the electronic mail address of the user (B) and identifying (certifying) the user (B). An HP and a registration HP for collecting registration data such as questionnaire responses from the user (Otsu) and registering it as data regarding the user (Otsu) are included.

The HD (not shown) in the system 1
D (Hard Disk Drive) has a data management DB (Data Base)
11 have been built. This data management DB 11 is an electronic mail (empty mail) sent from the user terminal 5.
The user is identified (authenticated) by managing the sender's (user's (person's) individual) 's e-mail address associated with the user by associating it with the unique e-mail address described below, and then This is a DB for managing the registration data transmitted from the terminal 5 in association with each other.

Next, a data management method for managing data using the system 1 according to this embodiment will be described with reference to FIGS. 1 to 3. 2 is a sequence diagram showing a data management method for managing various data transmitted from the user terminal 5 via the communication network using the system 1. Further, FIG. 3 shows images (a, b, c, d, e) displayed on the display 7 of the user terminal 5 and a processing image (A,
It is the figure which showed B, C).

First, the user (Otsu) who has recognized the URL of the authentication HP published by a television program or the like uses the Internet 2 via the base station 4 and the mobile phone network 3 from the user terminal 5 shown in FIG. Is accessed (step S1).
Then, the user (Otsu) inputs the published URL into the user terminal 5 as shown in FIG.
The authentication HP of the system 101 is accessed based on P (step S2). As a result, the system 1 accepts the access (step S3).

Next, in the system 1, as shown in FIG. 3 (A), the characters forming the electronic mail address are randomly (randomly) selected to generate a unique electronic mail address for each user. (Step S4). This unique e-mail address is an e-mail address (2
1, 22, 23, ...), and a specific generation method will be described later.

Next, in the system 1, the above step S4
The unique e-mail address generated in step 3, the time stamp (Time Stamp) indicating the date and time (time) accepted in step S3, and the initial value is false (false)
The processed flag (f) and the like are managed in association with each other.

Next, the system 1 transmits the authentication HP data to the user terminal 5 based on HTTP (step S6). The authentication HP data also includes data indicating an “authentication” button 31 linked to a destination (system 1) of an empty mail described later. The destination address of this empty mail is the unique electronic mail address generated in step S4. In addition, "Authentication" button 31
Is a button that consists of a character string (including numbers and symbols) that prompts you to send an e-mail, and can be clicked by the user (B) to execute the so-called Mail to link function. With this Mail to link function, when the user (B) clicks the authentication button, the default mailer (Mailer) on the user terminal 5 is activated, and the system 1 is addressed to the display 7 of the user terminal 5. This is a function to display a new e-mail creation screen.

Next, on the display 7 of the user terminal 5, as shown in FIG. 3B, an authentication HP image including an "authentication" button 31 and a "next" button 32 is displayed ( Step S7). Therefore, the user (B) is "certified"
Clicking the button 31 activates the mailer (step S8). Upon activation of this mailer, as shown in FIG. 3C, a new electronic mail creation screen with the system 1 as the destination is displayed. That is, the destination address of the system 1 is automatically entered in the destination entry field 33 of the e-mail creation screen. If you have finished sending the blank email, click the "Next" button 32
Go to the next process.

Next, the user (B) receives the title input field 3
4 and the mail text input field 35 without any characters (including numbers and symbols) being input (empty) and clicking the send button (not shown) on the email creation screen Based on this, an empty mail is transmitted to the system 1 side (step S9). Further, in the present embodiment, unlike the conventional case, the user (second party) does not need to disconnect the user terminal 5 from the Internet 2 once. The reason why it is not necessary to disconnect from the Internet will be explained later.

Next, the empty mail sent in step S9 is sent to the mobile mail server computer of the telecommunications carrier and then sent to the system 1 (step S10). As a result, the system 1 receives the empty mail (step S11). It should be noted that since the transmission source is a mobile phone, the conventional method (step S109)
Similarly, the mobile mail server computer does not check e-mail.

Next, the system 1 transmits "mail authentication in progress" display data to the user terminal 5 based on HTTP (step S12). As a result, the “mail authentication in progress” image shown in FIG. 3D is displayed on the display 7 of the user terminal 5 (step S13). In this “mail authentication” image, since the process to identify (authenticate) the user (B) is now being performed, the “confirm” button 36 will be displayed after several tens of seconds.
A message prompting you to click is displayed.

On the other hand, in the system 1, as shown in FIG. 3B, the electronic mail address (41) of the user (sender) (B) attached to the empty mail received in step S11 is Data management D in association with the unique email address (22) notified to the user (B)
It is managed in B11 (step S14). by this,
Since the user (B) can be specified (authenticated), it is possible to prevent a response due to a certain impersonation.

Next, the system 1 transmits registration HP data to the user terminal 5 based on HTTP (step S15). As a result, the display 7 of the user terminal 5
A registration HP image as shown in FIG. 3E is displayed on the screen (step S16). In this registration HP image, the notification of the identification (authentication) completion in step S14, the registration data input field 37, and the registration data selection field 38 are displayed. Then, the user (Otsu) inputs / selects the registration data (name, gender) and clicks the "Next" button 39 to transmit the data to the system 1 based on HTTP (step S17). As a result, the system 1
Then, the registration data is received (step S18). Then, in the system 1, as shown in FIG. 3C, the data management DB 11 is associated with the unique email address (22) of the user (B) and the personal email address (41) of the user (B). , The registration data (42, 43) is managed (step S19). In this way, the user terminal 5
Various registration data can be transmitted to the system 1 by mutual communication between the system 1 and the system 1. However, the user terminal 5 is disconnected from the Internet once, and the authentication H
When P is accessed, the process of step S4 is performed and a new unique e-mail address is assigned. In other words, even the same user (B) will be given a different unique email address for each session.

Next, referring to FIG. 4, step S of FIG.
A method of generating a unique email address in 4 will be described.

As shown in FIG. 4A, first, the length (number of characters) l (ell) of the unique electronic mail address is set (step S21), and then the random number n is generated (step S22). ). The method of generating this random number n is shown in FIG.
It is shown in (b). That is, first, the date and time (time stamp) when the access is accepted in step S3.
(t)) is acquired (step S31). Then, the number w of persons who have accessed the system 1 so far is acquired (step S32). Further, the memory usage m of the system 1 is acquired (step S33). This allows the Mersenne Twist
The seed (= m * t-w) used in the er method is derived (step S34). And based on this derived seed, Me
A random number n is generated by the rsenne Twister method (step S3)
5).

Then, returning to FIG. 4A, step S2
The first character of the mail address is determined by selecting the alphabet corresponding to the remainder m obtained by dividing the random number n generated in 2 by 26 (step S23). This first character is always expressed in alphabets, such as "a" when the remainder m = 0 and "b" when the remainder m = 1.
They are selected in alphabetical order as the value of m increases.

Then, again, the random number n is generated in the same manner as in step S22 (step 24). Then, for the second and subsequent characters of the mail address, a character (including alphabets and numbers) corresponding to the remainder m obtained by dividing the random number n by 38 is selected (step 25). This character is m =
Alphabet is used from 0 to m = 25, m = 26
After that, numbers from 0 to 9 are used in order, and after m = 36, a symbol such as "-" is used. Then, it is determined whether the number of characters forming the address is less than 31 (step 2
6) If the number of characters is less than 31 (Yes), steps 24 and 25 are executed again. On the other hand, when the number of characters reaches 32 (No), the 32 characters selected so far are set as one character string s (step 27).

Next, the data management DB 11 is searched to check whether or not the same character string s already exists (step 28). Then, if there is a duplicated character string s (Yes), the step 22 is performed again.
Start over. On the other hand, when there is no duplicated character string s (No), the character string s is written in the data management DB 11 (step 30). This writing process shows the same process as step 5 shown in FIG.

Next, referring to FIG. 5, step S in FIG.
The management of the personal e-mail address of the user (B) in 14 will be described.

In FIG. 5, first, based on the destination address (33) of the empty mail shown in FIG. 3 described above, the corresponding field (fiel
By extracting d), the inquiry about the unique electronic mail address 22 shown in FIG. 3 is performed (step S41).

Next, the unique e-mail address
It is determined whether or not there is data, that is, whether or not the unique electronic mail address 22 managed in step S5 and the destination address (33) of the empty mail match (step S42). Then, if there is unique e-mail address data (Yes), the time stamp (t) and the processed flag (f) managed in association with the unique e-mail address are stored in the data management DB 11. It is acquired (step S43).

Next, it is judged whether or not the reception date and time of the empty mail in the above step S11 is within the set allowable time from the time stamp (t1) (step S44). This setting allowable time is set to a short time (for example, several minutes) in order to reduce the possibility of access to the registration HP by impersonation as much as possible. Then, if it is within the set allowable time (Yes), the processed flag (f) is false.
It is determined whether or not (false) (step S45). As shown in step S5 above, since the initial value is managed as false, in the case of the first empty mail transmission after the user (B) has been notified of the unique mail address
It will be judged as false.

Next, in step S45, false
If it is determined to be (false) (Yes), the data management DB
The processed flag (f) managed in 11 is updated to true (step S46). As a result, even if the user (Otsu) is notified of the unique email address, it is determined to be true in step 45 in the case of the second and subsequent empty email transmissions.
You cannot browse P. Therefore, HP for registration again
If you want to browse, you need to start over from step S1 again and have a new unique e-mail address notified. Also by this, the possibility of access to the registration HP by impersonation can be reduced as much as possible.

Next, the data is managed by the data management DB 11.
The error flag is set to false (step S47).
Then, it is determined whether the error flag is false (true) or not (step S49), and if the process of the step S47 has been completed, since it is false, an authentication completion message is created (step S49). S50). This message is transmitted to the user terminal 5 as a part of the registration HP data in step 15 of FIG. And FIG.
As shown in (e), a message indicating the completion of mail authentication is displayed.

On the other hand, if it is determined in step S42 that there is no unique mail address data (N
o), when it is determined that the set allowable time is exceeded in step S44 (No), or the above step S44
Because it is the second empty mail transmission after 45
When it is determined that the error flag is not false (No), the error flag is set to true (step S4).
8). As a result, it is determined to be true in step S49 (step S49), and an authentication failure message is created (step S50). This message data will be transmitted to the user terminal 5 instead of the registration HP data in step 15 of FIG.

As described above, since it is not necessary to disconnect the user terminal 5 from the Internet 2 once, the user terminal 5
Before sending registration HP data to
It is not necessary to send the registration HP notification mail found in the related art described with reference to. Therefore, the user (Otsu)
Can browse the registration HP much faster than in the past, and thus can quickly send the registration data with good operability.

Here, it is not necessary to disconnect from the Internet once because the system 1 side is browsing the authentication HP unless the unique mail address assigned to the user (B) is changed. Because it can be grasped, in order to switch from the HP for authentication to the HP for registration,
This is because it becomes possible to deliver the image change information for the registration HP data only to the user terminal 105.

More specifically, on the system 1 side,
Explaining whether the user (Otsu) can understand that he is always browsing the authentication HP, when the user (Otsu) sends a blank email to the system 1 side,
