Abstract

PROBLEM TO BE SOLVED: To solve the problem that a global economy is prevented from development by an authoritative procedure such as making trade document and seal and signature by an executive, and that a public document issued from an autonomy and a certificate, etc., can not be received unless we go to a counter in a specified hour. SOLUTION: Declaration about tax, registration of various types of public documents, storage and documentation of papers for business, and inspection of these documents can be realized from a terminal after a specified certification by a site called a digital post. Vast amount of documents are searched easily because they are stored in XML description. Besides, a new document can be carried out at once because finite form of the documents is formatted and stored. Digital signature and digital signet are stored in a high priority database, and then putting seal on the document and issuance and distribution of the certificate can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to registration and use of a digital signature and a digital seal for a document and its authentication. In particular, with the development of the Web business, a system is provided that promptly prepares transaction documents, quickly seals and signs executives of companies and government offices, enhances security, and performs business efficiently. It also provides a system for instantly submitting, filing and viewing documents to regulatory agencies.

[0002]

2. Description of the Related Art Conventionally, for example, submission of documents to regulatory authorities,
Declarations were extremely complicated, and in some cases, they used various specialists, tax, government, and judicial scriveners, went to consultation counters, and spent a lot of time and money. The same was true for reading official documents and issuing certificates.

[0003] The exchange of business slips is also carried out by a large number of people, and in the case of high-value transactions and important transactions, a high-level person's signature and seal certificate are attached, and the time and labor during that period are high. Expenses had been paid.

[0004]

SUMMARY OF THE INVENTION For this reason, We
It is based on the demands of society that urgently need to issue, certify and certify documents, backed by the high speed and high security required for business transactions around the world via the Internet like business b.

[0005] The development of telecommunications information networks has given significant changes not only to business practices but also to social life. As in the past, it is not possible to overcome intense international competition with Taramanashi by making decisions on settlement. Therefore, the system according to the present invention can be provided to help the recovery of the stagnant Japanese economy.

[0006]

An object of the present invention is to improve such inconveniences, and any person who has been authenticated can access a public document and quickly prepare a document in response to a request, thereby making it possible for himself or herself. We can provide documents with digital signatures and digital seals of companies and bosses.

[0007] Not only in business but also in personal life, public documents can be easily browsed and issued, and the poor administrative services can be overcome. On holidays and during holidays, administrative windows close. It is difficult at present to apply for and receive various official documents and certificates while working, and the aim is to improve these.

[0008]

In order to achieve the above object, the invention according to claim 1 processes creation and authentication of important documents and official documents safely, reliably, and promptly in accordance with the IT age. Means.

[0009] In issuing and distributing documents and documents, the official seal,
The signatures and seals of the executives of the company are stored in an encrypted form, and are checked and executed after a plurality of checks.

The browsing of the internal data of the document and the downloading of the format at the request of the user can be performed by the authentication at the previous stage. The issuance and distribution of signed documents, digital seals, and certificates require authentication at a later stage.
This process is monitored and stored at a business or public institution site.

In an era of a global economy that spreads globally in an instant, an e-government is aimed at realizing an e-business environment in order to avoid an Internet crime such as unauthorized intrusion and falsification and prepare an e-business environment.

Document storage, authentication, electronic signature, electronic seal,
The inventor named the business site for registering, issuing, and distributing certificates a soliton, document storage and management system.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall configuration diagram of the system. This system is configured by connecting sites 2, 3, 4, 5, and 7 for registering, storing, and authenticating documents and electronic signatures to a communication network 1 such as the Internet.

One communication network is communication means represented by the Internet. Conventional telephone network (PSTN), IS
DN, ATM, optical fiber network, mobile (wireless) network,
Satellite communication networks are also included.

Five official Web sites such as i-mode (trade name of NTT DOCOMO) are connected to one communication network. According to the present invention, a website (both formal and unofficial), which has been rapidly spreading in recent years, is used as a portal, and various documents are registered, stored, and browsed at the request of the user.

Of course, 5 may be an unofficial site operated as a business as well as an official site,
It may be an official website operated by a country or local government that specializes in official documents.

Reference numeral 2 denotes an electronic form with an electronic signature, a document, and a site for performing browsing and search fee processing. Digital post service (Digital Post Office S)
service). Documents and forms include various transcripts managed by the municipality, resident's cards, land and real estate related to buildings, companies, shops, individuals, receipts, receipts, bills, etc.

In the DP (Digital Post) site, companies, stores, and individuals can receive and order slips and forms, register and issue them, browse past slips, forms, and document histories, The user provides a service for obtaining these copies. This configuration will be described later.

Reference numeral 3 denotes a storage site for documents, slips, forms, and digital signatures. Storing electronic signatures, which are also called electronic seals like registration of official seals, and setting priorities including the most important things such as signed documents and the storage of office documents, encryption, Store in clear text.

Reference numeral 4 denotes an authentication site. Provides services to prove that the electronic, signature, electronic seal, and signed documents belong to the user. It also issues an electronic signature certificate instead of a seal seal certificate.

Reference numeral 7 denotes a site such as a financial institution, a bank, a credit company, a post office, and the like, from which a fee collected from a user when performing various services and settlements is reduced.

Initially, the user registers 9
And registers a predetermined format document and electronic signature by management not shown. These operations are performed by management.

Reference numerals 13 and 14, which correspond to the windows of the local government, are servers for registering signed documents and electronic signatures. Reference numeral 15 denotes an image reader for reading documents, photographs, and the like. Reference numeral 16 denotes an encryption key issuing device for transmitting or transmitting important documents and electronic signatures.

Electronic authentication is an important factor in security so that it is never leaked outside or falsified by a third party. This security is the key to the success of e-business, and can be said to be an indispensable issue for the development of business on the Internet in the future.

The present invention does not refer to cryptographic element technologies related to security. . Here, a generally usable encryption method is used. As a data encryption technique, there is a secret lock encryption scheme and a public lock encryption scheme.

The secret lock cryptosystem (also called a common lock)
The communicating parties encrypt and decrypt with a common secret lock. In this method, since a common lock must be kept secret from each other, in electronic commerce, when performing many-to-many communication, there is a complication that a partner key must be managed for each partner.

In the public lock cryptosystem, it is not necessary to keep the lock secret for each transaction partner. Each person has two pairs of keys, and performs encryption and decryption with different keys.

Of the two keys, the secret key for decryption is kept secret by the owner, and the public key for encryption is made public. In the case of electronic commerce, the latter is more convenient. The present invention uses the latter method because an electronic signature is used for authentication in electronic commerce.

Reference numeral 19 denotes a dedicated line connecting the 2 DP sites, 3 storage sites, and 4 authentication sites. Since a confidential document and a digital signature are exchanged between the sites, a general communication network is not used. In addition, an advanced encryption is used.

Data that has arrived at the D / P site 2 from the storage site 3 and the authentication site 4 can be read and written by the above-described public key encryption.

In the storage site 3, a database is constructed according to the degree of importance. Naturally, high-priority data is stored using advanced encryption. This DP
The site has various functions for receiving and issuing texts, reports, and electronic signatures, and can be executed with a public key possessed by the user.

Reference numeral 10 denotes a user, and the figure shows the user's office, store, and home. 11 is the user's PC,
Reference numeral 12 denotes a fax with telephone.

Numeral 18 denotes a user's portable terminal which can access 5 Web sites through 6 base stations by mobile. 17 users, who are users, can browse documents from 5 Web sites as needed with 18 mobile terminal devices.

In electronic commerce (e-business), settlement is required instantaneously with time. As the global economy expands, its markets are growing and, at the same time, exposed to an ever more competitive world.

Creation of a document for settlement of a transaction, access to an electronic signature from a portable terminal device (portable telephone), decryption of an encryption, insertion of an encryption key into the portable device, issuance in a short time,
Receipt can be realized.

The more severe the competition, the more thorough the security must be. With just one document, a huge amount of money travels around the world instantly. We consider that four issuance sites are indispensable for issuing documents with electronic signatures to ensure security. This digital post has a function to check for wrongdoing, and if found, sends the data to the police site 20 connected at 19 to determine the culprit.

The user and the recipient of the user mutually transmit and receive an important document by holding an encryption key for cipher explanation.
Further, when simply reading an official document such as a resident's card, a copy of a family register, a real estate registry, etc., or downloading and obtaining only a document, an encryption key is not necessarily required.

However, if the member is registered in advance at the D / P site 2 and becomes a so-called member, he / she can access by the previous authentication using only the assigned password and telephone number. The D / P site stores who viewed what document and when, and a history of downloading and writing.

At present, administration of resident registration, transcript of family register, and seal certification are performed by the government at the municipal offices. According to the present invention, by using an encryption key, an important document can be obtained anywhere as long as there is a terminal device, and a document and an official document that can be viewed by a third party can be obtained.

In the near future, the world's three largest economies, the United States, Europe, and Asian countries will have digital signatures in a common format,
Official documents for business transactions, personal resident IDs, and copies of family register must be realized.

[0042] Commercial texts and documents are rapidly developed and need to be signed and signed by a company executive immediately, as they have developed into a global economy. Business people are active around the world, both at home and abroad.

Many texts and documents on transactions are similar in content and format. There are few examples of making it from scratch.
When we usually create sentences by operating on a personal computer,
You can easily create a document by recalling the contents of a previously created document and modifying the necessary parts.

Similarly, the user can call his or his own document stored in the DP and extract internal data to create a new document. The original version of the signed text is systematically stored strictly in the storage site 3 via the DP 2.

In the case of downloading the original or separately attaching an electronic signature or an electronic seal stamp of the user or the boss of the company to a new document, it is necessary to perform authentication from the authentication site 4 and an encryption key.

FIG. 2 is a diagram showing the configuration details of the two digital posts and their interaction with other sites. A digital post is a program that controls the system, an OS, an intermediate language, a valid check that performs signature verification, and a monitor that monitors text and document communication between the user and the five Web sites.
electronic format section that formats rival Watchers, sentences, and documents.

If the electronic format is an electronic commerce document, for example, a document can be created in a predetermined format with the name of a company or store. It will be converted into a final return and an official report.

The Digital Post has also made it much easier for office workers to file year-end tax returns at the end of the year. The same is true for self-employed blue declarations, which can be easily achieved without hassle.

XML Gen is used to convert data and text into XML.
(Extensible Markup Langua
ge). XML is a language capable of not only describing a document itself, but also describing a message when data is exchanged between systems by defining a document structure and tags.

The file describing the contents of the document and the file defining the document structure and tags can be handled as one content, so that the document itself displayed as a document on the Web browser is exchanged with the message data for commerce. Can be used as A language that is expected to become the standard for data formats.

Inserting a tab (style) in a document allows the sentence after insertion to be freely changed. By attaching tabs to text, the movement of documents and data between sites and systems will be smooth. The user can easily create a new document based on the data of the downloaded original document.

The intermediate language located at the digital post is:
The user owns various terminal devices. For PCs, Microsoft's Windows or Apple's Mac are the mainstream. However, there are many types of portable information terminal devices.

In recent years, the balm OS has gradually penetrated, but the portable telephone has become a compact browser, the OS has an itron, the Zaurus has a unique OS, and the Cassiopea has a Casio Pear. There are many with Win CE.

Since documents and documents created by any OS can be freely communicated with the user's terminal device, different OSs are absorbed by using an intermediate language. Therefore, the user has a feature that the user can communicate with the Web site and the digital post using his / her own terminal device.

The external interface unit is a connection and communication unit for connecting the digital post to other sites and the Web. First,
The user registers the personal signature and the original document at the window 9. The registration window is the same as before,
You may install it in a post office, a bank, or a convenience store.

In registering, 9 has a manager,
You may go through this person, or you may mail it. Also, an automated registering machine such as an ATM (automatic cash input / output machine) at a bank or supermarket may be installed.

The password and the encryption key are issued from the registration device. This registration procedure causes the reader to read the document with the electronic signature. If a password and an electronic signature are registered in advance at the two digital post sites, a password or an encryption key is used.

At the window where the manager is present, a password and an encryption key can be issued on the spot. Of course, you need to have your own certificate, and you may need a certificate or a health insurance card as well as a document guaranteed by a third party.

The information is transmitted from the window 9 to five Web sites. 5 may be an official site such as i-mode or a self-run site operated by a private company. Reference numeral 22 denotes a registration server on the Web site. The server performs a predetermined format and transmits the digital post via the 8 IP lines.

The received original text with signature or digital signature is converted into an electronic document format, converted into an XML document structure, and transmitted to the server 23 of the storage site 3 through the 19 dedicated line. In this case, since it is an original, it is encrypted and stored in the high-priority database 24 for the purpose of preventing intrusion of a third party.

If only the electronic signature is stored, it is also stored in the high priority signature database 25. As described above, XML has a structure in which a tag is inserted, and can indicate the level of confidentiality in the heading of the document structure.

It is also possible to discriminate the viewers according to the confidentiality. For corporate documents, general photos, managers,
Documents can be browsed by dividing into officers.

The user 10 can access 5 Web sites from home, regardless of whether the user is in a company, on a moving transportation, or on the road. As an example of a commercial transaction, if a negotiation is concluded during a meeting, the contracts are mutually exchanged.

The terminal in the conference room or 5 W
Access the website. Then, a model of the contract document is obtained from the digital post, and a contract document for the negotiation concluded in the current meeting is created. The contract is completed by downloading the signature from the digital post using the encryption key and attaching it to the created document.

This document creation is a document in which high-level confidential information has been input, and the imprint of the digital signature and the digital seal is instantaneously completed. Efficiency is by far the best, with few mistakes and mistakes.

When an electronic signature and an electronic seal are pasted on a document, a check is made by an authentication site 4 for the purpose of stricter security. The check in the first step is performed only with digital posts, and for highly confidential ones, an authentication site is used.

The authentication site 4 is preferably operated by a public organization of a government or a local government. Financial institutions such as private companies and banks with abundant financial power and high creditworthiness may establish and operate the site.

In order to guarantee the electronic title and the electronic seal stamp to be attached to the confidential document at a high level, the identity verification by the authentication site requires the user to bear a corresponding expense.

In the first step, the authentication means performs the confirmation with the digital post 2, encrypts the digital post 2, and transmits the encrypted data via the dedicated line 19.
7 is input. Next, the second step is confirmed. Similarly, the electronic signature and the electronic seal stamp at the storage site are taken out from the high-priority database 24 via the dedicated line and confirmed.

In the third step, the electronic signature and the electronic seal stored in the authentication site 4 are retrieved from the databases 28 and 29 and collated. If the three steps are confirmed and verified and there is no error, an electronic signature and an electronic seal are sent as requested. The authentication site 4 issues a certificate as necessary.

The process of delivering an electronic signature and an electronic seal stamp to the user is described in the digital post Arrival.
Monitored by Watcher. If there is an intrusion of a hacker or the like by a third party in the middle of the process, a warning is issued and the authentication work is interrupted, and the issuance of the electronic signature and the electronic seal is stopped.

Then, a search is made for the source of the occurrence of wrongdoing, and if it is illegal, appeal is made to the police. The police sites in FIGS. 1 and 20 are on a communication network and detect illegal acts related to authentication and strictly punish.

Since there is evidence of credibility, financial strength, and detection and penalties for illegal activities, the presence of an authentication site can obtain credibility from users. In addition, it is possible to prevent unauthorized entry. According to the present invention, it may be said that it is constantly under police supervision.

FIG. 3 is a flowchart showing a process of authenticating and issuing an electronic signature and an electronic seal stamp. In step S301, the user accesses the Web site using the encryption key in order to authenticate the electronic signature and the electronic seal stamp from the terminal device.

In this case, the encryption key is a card, a mobile phone,
Plug in terminal device. Enter your own phone number and password (password) to ensure security.

In S302, the request of the user is received in the Web site diagrams 1 and 5, and is converted into a fixed format and converted into a fixed format.
To digital post. Here, in the first step of personal authentication, a telephone number and a password are confirmed. If they are different, they are unconditionally excluded.

In step S303, a request from the user is transmitted to the digital post from the Web site. In step S304, authentication in the second step of identity verification is performed. Decrypt the code and confirm the identity of the person from the XML tag. If not,
Although excluded, the process jumps to S322 to check for unauthorized intrusion.

In step S305, all processes up to this point are monitored and stored as a function of the digital post. Trade to leave a history of access along with the purpose of the fraud detection.

For authentication, the data is transmitted to the authentication sites in FIGS. The contents and data are protected via the dedicated line 19 and by advanced encryption.

In step S307, in order to confirm the data received at the authentication site 4, the electronic signature and the electronic seal which are strictly stored in the storage sites shown in FIGS. During this time, the dedicated line 19 and the highly encrypted data are transmitted to the authentication site 4 and received.

In S308, the pre-encryption is decrypted, and in S3
09 and collate. If not, the process jumps to S322. At S310, the sequence during this time is watched by the function of the digital post 2 to make sure.

At S311, the data of the digital signature and the digital seal are sent to the digital post, and the data is collated with the authentication site for security. In step S312, the data is decoded to check the details. S if different at S313
Jump to 322.

At S314, the sequence up to this point is watched and stored in the memory. In step S315, the encryption is opened with the user's key, and in step S316, the encryption is transmitted to the user or a business partner specified by the user.

At S317, the received user or the person designated by the user has a common key and decrypts the code. In S318, the signature of the received and decrypted encryption is pasted on the document, or the signature and the issue of the certificate of the electronic seal stamp are selected.

In step S319, the electronic signature and the electronic seal that have been sent and decompressed are pasted on a document created by a personal computer or a terminal device. In S320, whether or not to issue a certificate is selected.

The certificate referred to here is a certificate for an electronic signature and an electronic seal stamp, and corresponds to a seal stamp certificate currently issued by the local government.

In step S321, the user can print the certificate issued by the authentication site and attach it to the document. Effective in supporting credit for transaction documents, slips, receipts, etc.

S322 is the digital post 2 Val
This is a process in which the sequence of all processes is checked by the id Check function, and in the middle of the process, illegal acts such as unauthorized intrusion and tampering are eliminated.

If the evidence of illegal activities is clearly found in S323, the police are notified in S324. Figures 1 and 2
The 0 police site and the digital post are connected by 19 dedicated lines, and the search for criminals starts immediately.

FIG. 4 is a flowchart showing registration of an electronic signature, an original of a document with an electronic signature, and an electronic seal stamp. The electronic signature and the electronic seal mentioned here differ only in the format, and there is no difference in the means for performing personal authentication.

In step S401, the user registers a document. This is performed at the registration window 9 in FIG. In this flowchart, the registration of a document is specified, but here, registration including an original document with an electronic signature, only an electronic signature, an electronic seal, and a plain text document is shown.

In step S402, a document with an electronic signature, an electronic seal,
Select the registration of the electronic signature. In step S403, if the electronic signature, the electronic seal, and the important document to which the electronic signature is attached, encryption is performed along with the document itself.

In step S405, in the process of issuing a key, in the case of managing confidential documents in a transaction, a plurality of keys are issued which are both owned and owned by the user.

Step S409 is for registration of an electronic signature and an electronic seal. Since these are the same kind as the conventional stamp certificate issuance, the confidentiality is high. The user can create a document and download his / her signature and electronic seal from the Internet as needed, and attach it.

In step S406, a key is issued for the sender and the receiver. The sender key is an encryption key, and the receiver key is a decryption and decompression key.

S407 indicates that the registration of the document, digital signature, and digital seal has been completed in the digital post shown in FIGS. In S408, the registrant debits the commission from the predetermined account. At the time of registration, at the same time that the encryption key is issued, a password (password) for initial authentication
Registration is also performed.

Step S410 is a process for registering and storing a plaintext document. Although it is not very confidential, it is used when using a digital post site instead of a format for document creation or a file for each time series. When browsing a document, an XML tag is displayed, so that the document can be searched at a glance.

For official documents such as resident's card, family register, excerpt, real estate register, etc., those which can be viewed by a third party, a reading key issued by the local government is separately prepared and registered during this process. You can also get it issued.

[0099] The browsing of a third party also involves privacy.
There are many places to be issues. Therefore, a key and a password are issued so that who can understand the relationship between the official document and the viewer for what purpose.

FIG. 5 is a flowchart showing a sequence of browsing a document by a third party and issuing a browsed document by the person. In step S501, the We terminal shown in FIGS.
Access site b to search for documents. In order to enter here, at least the first step of authentication by telephone number and password is required.

Step S502 shows a process of finding and browsing a target document. Documents that cannot be accessed by a third party are naturally excluded. Still, if the intrusion is made by any means, a warning is issued from the digital post and the police site 20 is notified.

Step S503 shows a process of downloading the browsed document. In step S504, it is determined whether the document is an original document with a digital signature. Since S505 is a document with a digital signature, an encryption key is required to issue it. If there is no encryption key, it is naturally excluded.

Step S506 shows the process of issuing a document with a digital signature. In step S507, a determination is made as to whether or not to transmit the email to a business partner or a related party. In the case of mail transmission, it is again encrypted with an encryption key and transmitted to the other party via a digital post. S511 shows the process.

In step S508, the record of the browsed document is specified on the digital post. The whole process of viewing, publishing and publishing what documents is documented.

Step S510 is a process for downloading a document without a digital signature and a digital seal. In S509, the expenses required for browsing and issuing documents are deducted from the predetermined account.

FIG. 6 is a flowchart showing a process of discarding a registered document, digital signature, and digital seal. If these personal identification stamps, including confidential documents, are involved in any trouble, or are misused or tampered with by others, discard the documents, electronic signatures, and electronic seals stored in the digital post and replace them with new ones. They may be exchanged for something.

[0107] However, although it cannot be absolutely discarded like an official document, there is also a means for stamping and storing an original on the original. In step S601, the user informs the user of the discard / deletion by Web.
Send to site 5.

In step S702, it is determined whether the discarded / erased document, signature, and the like are within the validity period. For documents and signatures,
There is also a way to set an expiration date and let it disappear from the digital post site after a while. Thereby, the security is enhanced, and the registration is made again after a predetermined period has elapsed.

If the validity period has passed, discarding is performed in S606 even if there is no notification from the user. If there is no notification and the processing is performed, the user is notified that the processing is to be discarded or deleted. If the user desires to re-register, he or she is requested to perform a registration procedure in the process shown in FIG.

In step S603, it is determined whether the document is an official document. If the document is not an official document, in step S604, the document and signature reported by the user are compared with the original stored in the digital post. In S605, it is determined whether or not to discard. If it is a deletion procedure according to the user's notification, S6
At 09, a judgment is made.

In the case of disposal, in step S606, all documents, signatures, and the like stored in the digital post site are disposed. In step S607, the history of discard is stored. S60
In the case of erasure, the data of the contents remains as it is. Therefore, the user has to pay for the cost of storage to the site.

If it is not determined in step S609 that the data is to be deleted or discarded, the cause may be due to a defect or error in the user's notification. The process ends without doing anything.
Notify the user to that effect.

If it is determined in step S710 that the document is an official document and cannot be discarded, it is determined in step S711 that the document is to be deleted. If the document or signature cannot be deleted, only the history is discarded in S607.
Remember that there was a notice of deletion. The digital post notifies the user of the reason why it cannot be discarded or deleted.

In S312, since the deletion is permitted, the document and the signature are deleted. In S607, the history is stored to notify the user of the deletion. S608
Debits expenses from a predetermined account.

According to the above-described embodiment, in the case of a business transaction, the troublesome document creation and authentication are stored in a digital post in a fixed form, so that the processing can be performed quickly. It can provide an effective means to survive intense corporate business competition.

The storage of public documents, the certification, and the issuance of certificates can also be performed 24 hours a day from the offices of local governments. Personal life behaviors can also be expanded.

A double or triple check is performed at the authentication site, and the supporting mail is sent to the URL (Uniform Res).
(Source Locator) to inform the user, so that the risk of spoofing and unauthorized use is small and the security can be kept high.

Another feature of the present invention is that a user can easily search for a document he or she needs from a large number of documents. This is because each document is described in XML, so that the document can be searched quickly by the tag.

An electronic seal stamp and an electronic signature (not shown)
The imprint of the seal is read by a fine scanner and stored in the database of FIG. Electronic signatures are performed in a similar manner. Signs by hand have the advantage that each person has a habit and cannot be imitated by others.

[0120] Even in the case of an electronic seal stamp, it can be read and stored electronically by a scanner as in the case of conventional registration of a real seal. The same applies to electronic signatures. In this case, it is better to register a unique typeface by hand so that it will not be imitated by others. In the era of internationalization, any language can be used today, but unlike passwords, it is important that you use well-defined fonts and styles so that others cannot imitate them.

[0121]

Since the present invention is constructed and functions as described above, in developing into a global economy and society, it is possible to proceed with negotiations quickly, make decisions promptly, and perform secure and secure payment. , Can improve business efficiency.

In personal life, whether on holidays or late at night, official documents can be issued and obtained 24 hours a day, 365 days a year, which is considered to contribute to the realization of e-government. .
