Description

  The present invention relates to management of electronic information via a communication network, and in particular, original information unique to the creation of electronic information is added, and electronic information with guaranteed originality is arbitrarily selected in an arbitrary format. The present invention relates to a technique for realizing disclosure or distribution at the time.

  In recent years, communication networks as information infrastructures have become widespread. For example, the Internet, which is a global information infrastructure that connects various communication networks, is mainly used to obtain information that is of interest to individuals from information or products provided by private businesses. The purpose of use is expanding, for example, for public services such as various application procedures to central government agencies or local governments.

  Stock exchanges that handle securities such as stock certificates and bonds are also being digitized for various types of information, and services that distribute such electronic information via the Internet are actually being implemented. Therefore, in the future, regardless of individuals and companies, it is expected that requests for disclosure or distribution of electronic information from customers will increase, and it is essential to enhance services that respond to this demand. .

  Under such circumstances, time authentication technology (time stamp) that gives information on when electronic information is created or transmitted / received has also started to be widely used. The time determined by the time stamp can be used for various purposes as attribute information of each electronic information. For example, when the specified storage period elapses, it is used to determine how long the electronic information should be stored. It can also be destroyed automatically. Recently, practical application of an electronic notary system or the like in a notary office using this time authentication technology has been started.

  In this way, documents based on electronic information (electronic documents) are very advantageous in that they can be stored and stored, easy and quick to retrieve, and can be easily copied compared to paper documents. However, there is a problem that if the content written like a paper document is erased or rewritten, it is easy to be found without leaving a trace, as compared with the case where the trace remains and is easy to find. There is a high risk that the electronic information will be copied and proceeded without your knowledge. Recently, criminal acts that cause damage by spoofing pretending to be a third party and acting on the network, or tampering with rewriting electronic information without permission have been increasing. For this reason, the importance of safely distributing electronic information while confirming identity (identity) on the Internet and guaranteeing the originality of electronic information has been pointed out, and a mechanism for realizing this has been required.

  Therefore, international standardization organizations or standards organizations such as ISO and Internet Engineering Task Force (ISOF) have established various standards to promote technical standardization in order to meet the above-described requirements. Specific examples of technical standardization include electronic signatures based on PKI (Public Key Infrastracture: an authentication infrastructure using public encryption key technology). This electronic signature technique is said to be capable of ensuring the originality of electronic information and confirming the identity of the creator (ie, electronic authentication). In other words, the creator of an electronic document sends a document that has been digitally signed and a certificate that proves that the document has been created to the recipient, and the recipient confirms that the certificate is valid. Check with the certificate authority to make sure that the document retains its originality.

  The government of each country recognizes that the electronic signature by the PKI is effective as a means to ensure the reliability (originality) of electronic information, and is in the process of enacting the electronic signature law to give legal background. . Legislation is advancing especially in many countries such as the United States and Europe, and has become one standard for measures to ensure the originality of electronic documents. In Japan, the “Act on Electronic Signatures and Authentication Services (Electronic Signatures Act)” was enforced in April 2001, and electronic signatures are publicly recognized as a means of ensuring the originality of electronic information.

  The electronic signature law includes (1) estimation of the authenticity of a digitally signed document (that the document was created by the holder of the electronic signature), and (2) identification of an electronic certificate issuing organization recognized by the country. It stipulates two points of the accreditation system of the accredited certificate authority, and these two points are independent, but in principle, when using an electronic certificate from a certificate authority accredited in (2) (1) The authenticity of the document is granted, and if an electronic signature by a certification authority other than (2) is used, the validity of the electronic signature is individually evaluated, and if valid, the authenticity of the document of (1) is given. It is thought that will be done.

  In this situation, focusing on electronic information handled by stock exchanges, the strictness and accuracy from various aspects are particularly important in disclosing or distributing electronic information handled or related information via the Internet. It is clear that other requirements are required. If the information sent from the stock exchange is altered on the communication route and reaches the customer, it is expected that it will be a big problem in society and market in terms of the public interest and influence of the information. Because. Furthermore, it is also very important to accurately control the disclosure time of electronic information so that securities transactions such as stocks 12 hours before the disclosure time are prohibited under the regulations of insider trading in the Securities and Exchange Law.

  The present invention has been made in consideration of such points, and the format of the electronic information is converted according to the customer's request while ensuring the reliability of the electronic information transmitted and received between the customer and the stock exchange. It is an object of the present invention to ensure disclosure or distribution at a specified time.

  The stock exchange information system of the present invention comprises a host computer provided in a stock exchange institution that issues electronic information upon receiving an information disclosure request, and an information terminal provided in the stock exchange institution, The information terminal of the exchange institution has an application function for designating part or all of the disclosure date and time, the disclosure method, the disclosure destination address, the format format, and the related file as information for disclosing the created electronic information.

When the storage function for storing information and the disclosure date and time specified by the application function are reached, the stored electronic information is disclosed on the Web page by the disclosure method or transmitted to the disclosure destination address. And an information disclosure function disclosed.

  In addition, a host computer provided in a stock exchange institution that issues electronic information in response to an information disclosure request, and an information terminal provided in each user institution, the information terminal of the user institution is the stock exchange Information for obtaining predetermined electronic information registered in an institution, or for registering or disclosing electronic information in the stock exchange institution, disclosure date and time, disclosure method, disclosure destination address, format type, and A format for developing electronic information in a format designated by the application function of the information terminal of the user institution, the host computer of the stock exchange institution having an application function for designating a part or all of the related files The originality is achieved by adding an electronic signature and time information to the expansion function and the electronic information expanded in the format. In the case of acquisition or disclosure of the electronic information, when the disclosure date and time specified in the application function has been reached, An information disclosure function for disclosing the stored electronic information on a Web page by the disclosure method or transmitting it to the disclosure destination address and charging for the electronic information acquisition, registration, or disclosure service. In order to do so, it has a billing function for performing billing calculation.

  In addition, a host computer provided in a stock exchange institution capable of accessing a database for storing various electronic information, and an information terminal provided in the stock exchange institution, the information terminal of the stock exchange institution is And a storage application function for designating part or all of file information related to the electronic information and format information in order to store the created electronic information, and the host computer of the stock exchange organization Provides a format expansion function for expanding electronic information in the format specified by the storage application function by the information terminal of the stock exchange institution, and adds an electronic signature and time information to the electronic information expanded in the format An originality ensuring function that ensures originality by storing the electronic information, and an electronic storage function that stores electronic information with the originality secured. It is characterized by having.

  In addition, a host computer provided in a stock exchange institution that receives an information verification request and notifies a verification result of electronic information, an information terminal provided in the stock exchange institution, and an information terminal provided in each user institution The information terminal of the stock exchange institution or the information terminal of the user institution has an application function for designating verification source information and verification contents, and the host computer of the stock exchange institution is connected to the application function from the application function. Based on the information, various information stored in the stock exchange institution is searched, the verification function for comparing with the verification source information, and the verification result obtained from the verification function, the information terminal of the stock exchange institution Or it has the verification notification function which notifies to the information terminal of a user organization.

  According to the stock exchange information system of the present invention, as the information for disclosing the created electronic information, part or all of the disclosure date and time, the disclosure method, the disclosure destination address, the format format, and the related file are designated. The electronic information is expanded in the specified format, and is stored in a form in which the originality is ensured by adding an electronic signature and time information, and is stored when the specified disclosure date and time is reached. Since the electronic information is disclosed on the Web page using the specified disclosure method or sent to the specified disclosure destination address, the original information is securely added to the electronic information handled by the stock exchange. In addition, it is possible to disclose or distribute the electronic information at a specified and accurate time, and it is generally spread communication such as the Internet. It is possible to ensure trust for the electronic information distributed via the road. As a result, electronic information can be distributed securely between the customer and the stock exchange on the Internet, and the customer can obtain it at an accurate time, so that safety and convenience can be significantly improved.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
First, “originality” that is important in the technical idea of the present invention will be described. Normally, when performing procedures such as application / notification to a government office, it is required that the application form or notification form be the “original”, not a copy. In other words, it is necessary that the originality is ensured (created by the person and not modified). These conditions are required not only for paper document procedures but also for electronic document procedures. The creation or disclosure of electronic information in the present invention is performed on the assumption that this originality is provided. In this embodiment, “originality” means
(1) The person who created the document has been confirmed (not someone who impersonated or created it).
(2) The content is complete without intentional or negligent modification (it has not been rewritten without its knowledge).
(3) The time of creation, disclosure, etc. is guaranteed.
Means that
In the embodiment shown below, “distribution” means limited disclosure to a specified individual (or organization), and “public” means that multiple people can view it. The term “disclosure” includes both “public” and “distribution”. Further, “information” represents electronic information unless otherwise specified, and “document” also represents an electronic document.

<Entire configuration of electronic information creation / disclosure system 1 with originality ensured>
FIG. 1 is a diagram showing a schematic configuration of an electronic information creation / disclosure system 1 (hereinafter abbreviated as an electronic information system 1) in which the originality of the present invention is ensured. The electronic information system 1 is a system constructed and operated in a stock exchange.
As shown in FIG. 1, the electronic information system 1 includes an electronic information acquisition unit 12, an electronic information distribution unit 13, a customer request reception unit 14, an information collection unit 15, an electronic signature provision unit 16, and a time information provision. The configuration includes means 17, information storage means 18, information verification means 19, and originality ensuring means 11. The person in charge can access the electronic information system 1 from the information terminal 2 via the electronic information acquisition means 12. Further, the information terminal 3 of a customer (individual or company) outside the system accesses the electronic information system 1 via the communication network 4, and the electronic information system 1 creates or searches corresponding information upon receiving a request from the customer. Thus, it is configured to construct desired electronic information and send it back to the information terminal 3 or other information terminal (not shown). The electronic information system 1 is connected to a charging system 7 having a charging database 8. Speaking of the configuration described above in relation to the client / server system, the electronic information system 1 can be positioned on the server side, and the information terminals 2 and 3 of the person in charge and the customer can be positioned on the client side.

The main functions of each means of the electronic information system 1 shown in FIG. 1 are described below, but it should be noted that the functions are not limited to these. Other functions of each means will be described in four basic processes of the electronic information system 1 described later.
The electronic information acquisition means 12 has a function of acquiring information created by the person in charge via the information terminal 2 and registering it in the system. Specifically, it mainly inputs electronic information (usually means uploading an electronic file because it is done in units of files), converts the format of the acquired file, registers the electronic file after format conversion, and approves the registration information And management, disclosure method, disclosure destination, disclosure time designation, and verification information registration. The information terminal 2 may be configured to be connected to the communication network 4. In this case, the electronic information acquisition unit 12 acquires electronic information via the communication network 4 in the same manner as a customer request reception unit 14 described later.
The electronic information distribution means 13 has a function of distributing information created by a person in charge to customers. This includes distribution in response to customer service requests. Specifically, authentication of a customer requesting distribution, Web server processing for downloading target electronic information (file) on the customer side, distribution of download information, and processing of distribution notification are performed.

The customer request receiving means 14 has a function of receiving identification information related to desired disclosure information selected by the customer. Specifically, the process of authenticating the customer and the input of the information when an arbitrary conversion format, disclosure method, disclosure destination, and disclosure time are selected by the customer are performed.
The information collecting unit 15 has a function of acquiring necessary information from the database in accordance with requests from a person in charge and a customer.
The originality ensuring means 11 has a function of giving seal data, an electronic signature, and time information to electronic information (file) to guarantee originality.
The electronic signature giving means 16 has a function of giving an electronic signature to electronic information (file) in order to guarantee originality.
The time information adding unit 17 has a function of acquiring an accurate time from the external time transmitting unit 5 and adding time information to the electronic information (file) in order to guarantee originality.
The information storage unit 18 has a function of storing electronic information that is processed by the electronic document system 1 and whose originality is guaranteed in a storage unit (for example, the database 6).
The information verification unit 19 has a function of acquiring and displaying related information registered in the database 6 when, for example, it is desired to browse the disclosure time regarding the registered information.

  The billing system 7 and the billing database 8 are used to automatically calculate the service price for information requests by users, but are not deeply related to the technical idea of the present invention, and thus detailed description thereof is omitted. In addition, the information terminals 2 and 3 which are input means from the person in charge as the client and the customer are shown one by one for the sake of simplicity, but it goes without saying that a plurality of information terminals may exist. Absent. Any of these information terminals can be used for general information processing and can access a communication network, such as a desktop computer, a laptop computer, a notebook computer, a handy computer, and a portable information terminal (PDA). There is no particular limitation, and the detailed configuration thereof will be described later. However, those skilled in the art will understand a data processor or central processing unit (CPU), a memory, a user interface, a communication interface circuit, a bus, and the like. It will be clear that this is included.

The communication network 4 is for connecting the electronic information system (server) 1 and the customer (client) to each other, but interconnects with other networks (not shown) or sub-networks (not shown). For example, a local area network (LAN), a city data (metropolitan) network (MAN), a wide area network (WAN), or a large-scale network (Internet) may be implemented.
Further, the communication network 4 does not limit the type of access service (for example, public switched telephone network (PSTN), integrated digital communication network (ISDN), digital subscriber line system (DSL), asynchronous transmission mode (ATM), etc.). . In addition, the communication network 4 may be of a protocol type (eg, wireless application protocol (WAP), transmission control protocol / Internet protocol (TCP / IP), NetBIOS extended user interface (NetBEUI), or internetwork packet exchange / sequence Packet switching (IPX / SPX, etc.) is not limited.

Next, basic processing performed in the electronic information system 1 will be described. This can be roughly divided into four.
(A) Providing originality to electronic information created by the person in charge for disclosure:
(B) Electronic information services with guaranteed originality as requested by customers:
(C) Storage of electronic information whose originality is guaranteed upon request from the person in charge:
(D) Verification of electronic information whose originality is guaranteed by a request from a person in charge or a customer:
It is.

(A) Processing procedure for providing originality to electronic information created by a person in charge:
The person in charge refers to a person who accesses the electronic information system 1 from the information terminal 2 to create or register electronic information. Here, a process procedure until the originality is automatically given to the electronic information in the process of creating the electronic information by the person in charge and this is registered in the database 6 is shown. FIG. 2-A and FIG. 2-B are flowcharts showing the processing procedure.
As shown in FIG. 2-A, electronic information is created by the person in charge (step S20). This electronic information is disclosed information that is disclosed at the request of the customer later in the basic process (B), or electronic information that is verified by a person in charge in the basic process (D). Electronic information is, for example, a stock price certificate, listing certificate, listing date certificate, or financial statement certificate, but the same information that is submitted to administrative agencies such as the Financial Services Agency, as well as notification information from the stock exchange. The type and contents of information are not particularly limited. Moreover, the software application used for information creation is not limited. For example, it is assumed that electronic information is created by an arbitrary application that handles electronic information, such as a Microsoft product or an Acrobat product.

  The electronic information acquisition unit 12 of the electronic information system 1 receives the electronic information transmitted from the information terminal 2 in response to the selection of “Registration” on the menu screen as shown in FIG. At this time, in order to identify the person in charge, unique identification information (for example, user ID, password, biometric information, or these) is started. Request). Next, in step S22, the electronic information acquisition means 12 authenticates whether or not the person in charge is permitted in advance as a system user, for example, by referring to a table in which the accessor is permitted. If the person in charge is permitted, the process proceeds to the process for registering the input electronic file in the database 6 (the process in the broken line frame in FIG. 2A). On the other hand, when the person in charge who is not permitted can determine to access the electronic information system 1, the electronic information acquisition unit 12 rejects the access (step S23).

The registered electronic file is information that may be disclosed (published or distributed) later. For this reason, in the next step S24, the electronic information acquisition means 12 displays a selection screen as shown in FIG. 8B on the information terminal 2, for example, and the registration information disclosure type (publication by the Web server, individual use) Distribution to users, storage without disclosure), disclosure method (email, download, etc.), disclosure address, disclosure date and time, format format for registration (eg, XBRL, PDF, XML, text, bitmap, etc.), Furthermore, the person in charge specifies whether or not there is a related file in the registration information. The related file refers to past registration information associated with registration information. For example, a stock certificate of a certain brand as of January 1, 2004 and a stock certificate of the same brand as of January 1, 2005 are related. Accordingly, when the 2005 stock price certificate is registered, the 2004 stock price certificate (1) is designated as a related file (step S26). Further, in the present embodiment, as shown in the related file designation screen of FIG. 8C, the related contents indicating the relationship with the past registration information such as replacement, addition, and subset are specified. (Step S27).
The relevance may be automatically set on the electronic information system 1 side based on an arbitrary key item such as a brand name or company name, in addition to the designation based on the judgment of the person in charge.

  Once electronic information is disclosed, it cannot be kept secret thereafter. For this reason, it is important for the stock exchange to carefully decide whether or not to disclose information and to prevent unintended disclosure from the standpoint of maintaining confidence in customers and society. Therefore, the electronic information acquisition means 12 executes an approval process and requires approval by an approver designated before disclosure (steps S28 and S29). For example, when the person in charge needs to approve the target electronic information and designates the approver on the approval confirmation screen as shown in FIG. 8D, the electronic information acquisition unit 12 uses the approval process shown in the flowchart of FIG. Execute.

As shown in FIG. 3, the approval process first notifies an approval request “Please approve of certain electronic information” to the approval designated person in step S50. This is because each electronic information requiring approval is automatically given a unique approval number that can identify it, and further, as shown in the confirmation screen of FIG. Since it is configured to designate an approver when necessary, the electronic information acquisition unit 12 distributes a notification with an approval number for requesting approval from the approver via e-mail, for example. Can do.
It is assumed that the approver who has received the notification in which the approval number is written also has an access permission right to access the electronic information system 1 as in the case of the person in charge. For this reason, in step S51, the electronic information acquisition unit 12 requests the approver to input identification information (user ID, password, biometric information, or a combination thereof). At the same time, input of an approval number is requested in order to designate which electronic information is to be approved.

  Next, in step S52, the electronic information acquisition means 12 stores the list of approvers stored in the database 6 or the like based on the approval number input by the approver and whether or not the item has been requested by the approver. Check by referring to the list. If the approver has designated an approval number that has not been requested due to an input error, it is requested to input the correct approval number again. In this way, the approval process is prevented from being executed without the knowledge of an unscheduled approver. When the approval number requested by the approver is input as scheduled, the electronic information acquisition unit 12 downloads the corresponding electronic information from the database 6 and outputs it on the screen (step S53).

  Next, in step S54, an approval confirmation screen as shown in FIG. 8E is output in order to input a judgment as to whether or not the approver approves the output electronic information. The electronic information acquisition means 12 determines whether or not the approver has pressed the button to approve this screen (step S55). If approved, the approver, approval date and time, etc. are left in order to leave the approval result as history information. Is recorded as related information of electronic information (step S58). In step S59, the person in charge is notified of the approval by the approver as an approval result by e-mail or the like, and the approval process is terminated. On the other hand, if the approver does not approve in step S55 (in the case of pressing a button that does not approve), the person in charge is notified of the unapproved result by e-mail or the like (step S56), and the unapproved state is indicated. The approval process is terminated with the hold (step S57).

  Even if the approval process shown in step S29 of FIG. 2-A is executed in this way and if the approval process is not performed in step S28, the electronic information acquisition unit 12 next sends the electronic information to step S24 in step S30. Convert to the format specified in. In this case, the number of formats that can be specified by the person in charge is not limited to one. When the person in charge designates a plurality of format formats, the same information is expanded into a plurality of formats. Note that the person in charge may automatically specify the format format to be developed according to the type of electronic document, etc., without selecting a specific format format.

  Next, in step S31, if the person in charge designates whether or not to give visual imprint data, that is, a so-called electronic seal stamp, to electronic information, and chooses to give imprint data, it is shown in FIG. 8 (f). As shown in FIG. 8G, a screen for designating what kind of imprint and what position to add to the electronic information is designated.

  The processing so far has been performed by the electronic information acquisition means 12, but the subsequent processing is handled by the electronic signature giving means 16, the time information giving means 17, and the information storage means 18 centering on the originality ensuring means 11. To do. Based on the designation relating to the seal imprint in step S32, the originality ensuring means 11 gives seal data to the electronic information in step S33. As described above, the electronic information after the format conversion in which the related file, the approval information, and the seal impression data are added as necessary based on the contents designated in step S24 is registered in the database 6 (step S34).

  Next, the originality ensuring means 11 checks whether or not the designated disclosure date has been reached (step S35). This disclosure date and time check uses an accurate electronic time that can be acquired from the time transmission means 5 outside the electronic information system 1. That is, a transmission station of time information such as telephone JJY, standard radio wave, FM broadcast time signal, etc. is used as an external time source, and for example, an FM receiver or the like, a highly accurate external standard time (hereinafter, referred to as timekeeping device) timed by a time station of the transmission station. The time signal generated based on the “external time” is received, and the external standard time is acquired and input based on the time signal. Note that a receiver that receives standard radio waves may be used instead of the FM receiver, and GPS time information may be received and can be changed as appropriate.

  If it is determined that the disclosure date and time has been reached by referring to the external time, and if the electronic information requires approval, the originality ensuring means 11 checks whether the approval procedure has been completed. (Step S37). As described in the approval process of FIG. 3, since there is electronic information that is not approved by the approver and registered in an unapproved state (step S57), the person in charge is notified of the approval request at this stage. This is because (Step S38) is required to complete the approval procedure. When the approval is finally finished, the electronic signature giving means 16 then creates an electronic signature by obtaining and encrypting the hash value of the target electronic information based on the format and relevance information described above. To do. At this time, since an electronic certificate indicating that "XX Stock Exchange has created" is encrypted together, an electronic signature using an electronic certificate with the name "XX Stock Exchange" must be generated become. The electronic signature attaching unit 16 attaches this electronic signature to the electronic information registered in the database 6 (step S39).

  As is apparent to those skilled in the art, a hash value is a fixed-length value generated from a given original text using an irreversible one-way function (hash function), and is also called a message digest. is there. Since it is extremely difficult to obtain electronic information of the original text from the hash value or to create electronic information of different sentences with the same hash value, whether or not it is identical to the original electronic information by comparing the hash values Can be confirmed.

Next, in step S40, the time information adding unit 17 acquires the accurate external time described above and adds it to the electronic information as the current time (including date). This is a so-called time stamp known to those skilled in the art. Like a digital signature, a hash value related to electronic information is obtained by adding a time stamp, sent to an arbitrary time stamp company via a communication network, and is sent back together with accurate time information using an external time. It may be. By embedding the returned time stamp in the electronic information, it is possible to create electronic information with a time stamp.
By adding the electronic signature and time information as described above, the originality required is (1) the creator is not created by impersonation or copying, and (2) the content is complete without alteration. It is possible to create electronic information that ensures (3) that the time of creation or the like is guaranteed.

Next, in step S <b> 41, the information storage unit 18 stores again the electronic information in which the originality is ensured in the database 6. At the time of this storage, the storage time and the registrant (that is, the person in charge of the electronic information system 1 that created and registered the electronic information) information are linked and stored.
In the present embodiment, the electronic information in which the originality is ensured in step S41 is stored in the database 6, but may be stored in a database different from the database used in the processing up to step S40. Needless to say.

  Further, when the disclosure date and time designated in step S24 is reached, the electronic information distribution means 19 discloses the target electronic information in the designated format format to the designated disclosure address destination by the designated disclosure type and the disclosure method.

As explained above, in the service that gives originality to the electronic information created by the person in charge, when storing the electronic information created on the stock exchange side, the electronic certificate with the name of the stock exchange is used. While giving an electronic signature, time certification (time stamp), and seal stamp data, it is possible to develop it into multiple formats (formats), associate information related to the electronic information, and further, an approval process if necessary Because it is configured to register after passing through, the electronic information of the approved contents with guaranteed originality must be disclosed (published or distributed) accurately in the specified date and time in any format specified by the customer Is possible.
Therefore, it becomes possible to use electronic information distributed through a generally popular communication path such as the Internet with peace of mind.

(B) Procedures for providing electronic information services with guaranteed originality as requested by customers:
Next, in response to a request for disclosure of predetermined electronic information from a customer (user), the stock exchange collects, shapes, and distributes information collected in advance from listed companies and participants. Indicates. 4A and 4B are flowcharts showing the processing procedure. Here, “registration” means that an external individual (organization) gives electronic information to the person in charge of the stock exchange, and “acquisition” means that an external individual (organization) records on the stock exchange. Or it shall mean acquiring registered electronic information.
As shown in FIG. 4-A, a person who desires to request disclosure or registration of electronic information tries to access the electronic information system 1 via the information terminal 3 (step S70). Specifically, for example, an electronic information providing page on a website set up by a stock exchange is clicked. In response to this, the customer request accepting means 14 of the electronic information system 1 uses unique identification information for identifying the user who wishes to use the user (for example, the user's name and address, etc.) If an ID, a password, or the like is given, an input of such information, biometric information, or a combination thereof is requested (step S71). The customer request accepting unit 14 determines whether or not to permit access to the electronic information system 1 based on the input identification information (step S72). For example, referring to a list of persons who have obtained information for criminal purposes or who are attempting to obtain information by impersonation, access can be denied if the person is an appropriate person (step S73).

  Next, the customer request accepting means 14 displays a usage content selection screen on the information terminal 3 for the user who has permitted access. The user selects one of (1) information displayed as usage details, (2) registration, or (3) disclosure, and then sequentially inputs more specific specified items. I will do it.

(1) When “Acquire” is selected in Step S74:
In step 75, the customer request accepting means 14 determines which type of information the user holds on the stock exchange (for example, listing related information, futures / Understanding the range of options trading related information, stock proof information, exchange information, etc., and what range (eg, initial listing, closing price of specific stock, dividend forecast, etc.) To do. Here, FIG. 9A shows an example of a screen for selecting the classification of acquired information, and FIG. 9B shows the specific proof information when “certification information” is selected in FIG. 9A. FIG. 9C is a screen example for selecting a specifiable range condition when “stock price certification” is selected in FIG. 9B. It may include. FIG. 9D shows an example of a screen for selecting a format format of acquired information, FIG. 9E shows an example of a screen for selecting / specifying a disclosure destination and a disclosure method of acquired information, and FIG. 9F shows an acquisition. It is an example of a screen at the time of downloading information. Note that these screen examples are merely examples and are not limited. In step S76, the information collecting unit 15 searches and extracts necessary information from the database 6 based on the designation information obtained by the customer request accepting unit 14, and generates electronic information arranged in a form desired by the user. To do.

  Next, in step S77 shown in FIG. 4-B, the information collecting means 15 determines whether the generated electronic information has a content that requires approval, and if necessary, performs an approval process on the person in charge of the stock exchange. A request is made to execute (step S78). It is assumed that what kind of electronic information requires approval and which person in charge is requested in advance. The requested person designates the approver and notifies the approval request, which is the same as the procedure in FIG. 3 shown in step S29 in the procedure (A), and will be omitted.

  Next, the information collecting means 15 further gives seal data to the electronic information generated in step S76 and appropriately approved (steps S80 to S82). In step S83, a billing process is performed to collect a fee for the information providing service. The billing process may be performed by providing billing means in the electronic information system 1, but in this embodiment, the billing process is executed by the external billing system 7 as shown in FIG. A typical accounting process is calculated based on what information is provided in what amount, but can be changed as appropriate.

  Next, confirmation of end of approval (steps S84 to S86), addition of an electronic signature (step S87), addition of time information (step S88), storage in a database (step S89), disclosure to a specified disclosure destination ( Step S90) is executed, but this is the same as the corresponding processing in steps S36 to S42 in the procedure (A), and will be omitted.

(2) When “Register” or “Public” is selected in Step S74:
If the usage content selected by the user is “registration”, the customer request accepting means 14 further designates a person in charge of registration (may be a department in charge), a disclosure method, and a disclosure destination address. These pieces of information are input (step S91). On the other hand, if the usage content selected by the user is “public”, a public method and a public destination are input (step S92). In step S93, the disclosure time, format format, and the like are input. Next, in step S94, the customer request accepting means 14 inputs (uploads) electronic information provided by the user. Next, if there is a related file for the uploaded information, the person in charge designates the related file (step S96), and further creates relevance information between the related files (step S97).

  After that, as shown in FIG. 4-A and FIG. 4-C, “Registration” and “Publication” are both approval process, conversion to a specified format, imprint data assignment, billing process, approval confirmation, and electronic signature assignment. The time information is assigned and stored (steps S100 to S112), but the specific contents thereof are the same as the corresponding processes of the same names in steps S28 to S42 in the procedure (A), and the description thereof is omitted. To do. Then, in step S113, notification to the person in charge or publication to the designated publication destination is performed. In the case of “registration”, since the information does not go out of the stock exchange, the present embodiment is configured not to perform the process related to the approval process and confirmation of approval.

  As described above, in the electronic information providing service in which the originality is guaranteed in response to a request from the customer (user), even if the information obtained from the user is registered or disclosed, Even when acquiring information sent from the stock exchange, it is configured to give an electronic signature with an electronic certificate having the name of the stock exchange and a time proof (time stamp). Electronic information to be distributed can show highly reliable information with originality secured. Furthermore, notification to a person in charge in the stock exchange and storage in a database can be surely performed at a designated time while guaranteeing the originality.

  In addition, after the stock exchange disclosed the electronic information that passed through the electronic information system 1 to the customer, the customer decrypted the electronic signature embedded in the electronic information, and whether or not the falsification was made based on the obtained hash value. Can be verified. For this reason, regardless of the information acquisition route, the originality of the electronic information is guaranteed by the stock exchange, the electronic certificate has not expired, or has been tampered with since the time stamp until now. It is possible to confirm whether or not the electronic information is reliable. This is very effective for confirming the credibility (originality) for a third party who is unable to specify the route to obtain the electronic information due to various distribution of the acquired electronic information. is there.

  For the electronic information providing service according to the customer's request described here, for example, disclosure information and various materials of stock exchanges nationwide and JASDAQ listed companies can be viewed on the customer's information terminal through the Internet. Includes network services. This network service allows you to view timely disclosure documents (financial results, earnings forecasts, dividend forecasts, etc.), mass ownership reports, treasury stock purchase status reports, securities reports for listing applications, etc. Although the document is printed or stored, the present invention makes it possible to implement a document or report whose originality is guaranteed at a designated processing time.

(C) Regarding the procedure for storing electronic information with guaranteed originality as requested by the person in charge:
Next, a processing procedure for storing electronic information whose originality is ensured in response to a request from the person in charge will be shown. FIG. 5 is a flowchart showing the processing procedure.
As shown in FIG. 5, storage information is created by the person in charge (step S120). The software application used for creating information is not limited. For example, it is assumed that electronic information is created by an arbitrary application that handles electronic information, such as a Microsoft product or an Acrobat product.

  The electronic information acquisition means 12 of the electronic information system 1 inputs the storage information (electronic file) transmitted from the information terminal 2. At this time, in order to identify the person in charge, in step S121, The input of unique identification information (for example, user ID, password, biometric information, or a combination thereof) is requested. In step S122, the electronic information acquisition unit 12 authenticates whether or not the person in charge is permitted in advance as a system user, for example, by referring to an accessor permission table. If it is an authorized person in charge, the input electronic file is registered in the database 6 (step S124). On the other hand, when the person in charge who is not permitted can determine to access the electronic information system 1, the electronic information acquisition unit rejects the access (step S123).

  Further, in step S124, the processing contents are selected, such as the type of the imprint data, the position where the imprint data is added, the format, and the presence / absence of a related file. Next, in step S126, if there is a related file for the stored information, the electronic information acquisition unit 12 causes the person in charge to specify the related file and creates the relevance information (step S127). After that, after conversion to a designated format (step S128), imprinting data is added (steps S129 to S131), it is once registered in the database 6 (step S132), an electronic signature is added (step S133), and time information is added (step S133). Step S134) is performed. In step S <b> 135, the information storage unit 18 stores the electronic information whose originality is ensured by the processing so far in the database 6. Since these specific contents are the same as the corresponding processes of the same name in the above (A) and (B), the description is omitted. Note that information such as storage date / time, storage requester, and approver is also recorded as a storage log while being associated with the storage data (step S135).

  As described above, in the service that stores electronic information whose originality is ensured in response to a request from a person in charge, an electronic signature using a digital certificate and a time certificate (time stamp) are provided. For example, important electronic information such as timely disclosure materials (new product information, executive personnel information, or financial results information) that may affect the stock price of listed companies, etc. are secured. It becomes possible to store in. As a result, when the electronic information is given value as objectively reliable information, it can be immediately proved by indicating that it is stored at the stock exchange.

(D) Procedures for verifying electronic information that is guaranteed to be original as requested by customers:
Next, a processing procedure for verifying electronic information according to a request from a customer or the like will be described.
For example, a customer has requested distribution of listing certification information about Company A and has already obtained it. After that, there was a change in the listing information about Company A, and we obtained further listing certification information from the third party. There is a demand for grasping the relationship between two listing certification information, such as whether the listing certificate obtained earlier is information replaced or added later. In such a case, the electronic information system 1 searches and verifies various electronic information and related information recorded in the database with the originality ensured, and notifies the verification result. FIG. 6 is a flowchart showing the processing procedure. Such a request is generated not only by the customer but also by a person in charge within the stock exchange. For example, the person in charge in the stock exchange wants to view the disclosure history for the stock certificate information of company B. At this time, the verification result processed by the electronic information system 1 is an internal notification.

  As shown in FIG. 6, first, verification information is prepared by the user, and the electronic information system 1 is accessed via the information terminal 3 (step S140). At this time, in order to identify who the user is, the customer request accepting unit 14 of the electronic information system 1 has unique identification information (for example, a user ID, a password, biometric information, or these in step S141). Request combination). Similarly, when the person in charge prepares the verification information and accesses the electronic information system 1 via the information terminal 2, the electronic information acquisition unit 12 of the electronic information system 1 identifies the person in charge. To input the unique identification information. In the following, verification of electronic information according to a request from a user will be described as an example, but verification according to a request from a person in charge is the same.

  In step S142, the customer request accepting means 14 (in the case of a request by the person in charge, the electronic information acquisition means 12, the same applies hereinafter) indicates whether or not the user has been authorized in advance as a system user. If it is authorized, the electronic information to be verified is registered in the database 6 (step S144). On the other hand, when it can be determined that an unauthorized person tries to access the electronic information system 1, the customer request accepting unit 14 rejects the access (step S143).

  Next, in step S145, the customer request accepting unit 14 outputs a screen for allowing the user to specify what kind of verification processing is specifically performed on the registered information to be verified. For example, in addition to specifying to verify the browsing request and disclosure history for verifying related information such as replacement and addition described above, verify the same content information registered in other format formats Or instructing to verify records at the time of registration, such as disclosure time, creator, and approval records.

  Next, in step S146, the information verification unit 19 searches for and acquires related information registered in the database using the electronic signature value of the registered verification information as a reference key. Since various kinds of electronic information are recorded in the database 6 in a state where the originality is ensured by the electronic signature and the time certificate (time stamp), the search based on the electronic signature value can be executed. Here, if verification information and related information can be uniquely and comprehensively searched using information other than the electronic signature value, the information may be used as a reference key. When the information verification unit 19 passes the information obtained as a result of the verification to the customer request reception unit 14, the customer request reception unit 14 outputs the information to the information terminal 3 to notify the user (step S147). The information can be browsed or downloaded (step S148).

  As described above, in a service for verifying electronic information in response to a request from a customer or the like, an electronic information system 1 is used to create an electronic signature and time certificate, which are disclosed or distributed Since information is configured to be registered in the information verification means 19, related information relating to registration information, a log relating to an approval process such as a registrant or an approver, a log relating to use (passing) of the electronic information system 1, and different Electronic information recorded in the format can be searched. In particular, since originality information (for example, an electronic signature value) of electronic information whose originality is ensured is referred to as a unique key at the time of this search, related information desired by a customer or a person in charge can be acquired reliably and promptly. be able to.

  In this embodiment, each constituent unit of the electronic information system 1 executes the series of processes described above to control the information terminal 3 of the user on the client side or the information terminal 2 of the person in charge inside the stock exchange. However, the present invention is not limited to this. As is often done in the client / server system type, in order to reduce the burden on the electronic information system (server) 1, input / output processing is performed by the browser on the information terminals (clients) 2 and 3, and the result is electronic information. You may comprise so that it may transmit to the system 1.
