Description

Electronic trade transaction server, seller's client, buyer's client, and integrated management method for electronic trade transaction method

The present invention relates to an electronic trade transaction server, a client for a seller, a client for a buyer, and an electronic trade transaction method for realizing a business model in which a trade procedure is electronic. In particular, by using a public key certificate issued by another certificate authority It relates to an electronic trade transaction server for electronically processing secure international trade transactions, a client for sellers, a client for buyers, and an electronic trade transaction method.

In recent years, electronic commerce (EC: Electronic Commerce) is rapidly developing, and in some regions, the "Electronic Signature Act" necessary for the electronic commerce to have legal binding force has been established. The current trade procedure treats the bill of lading issued by the shipping company as the securities in which the subject cargo is embodied, and the holder of the bill of lading ultimately has the right to receive the cargo from the shipping company at the place of import.

As described above, in the current laws and treaties, it is premised that the bill of lading be prepared in writing, and digitalized contents of the bill of lading cannot be legally protected as a bill of lading. As a method of digitalizing such trade procedures to receive legal protection, a method of binding all trade parties under one rule can be considered. In this method, the participant needs to be issued a public key certificate from the same Certification Authority (CA). Usually, a certification authority issues a public key certificate corresponding to a private key possessed only by a specific subject, that is, an individual or a company, and performs effective management of the certificate. When an electronic signature using a public key certificate is used for actual transactions, the certification authority needs to confirm that the subject is real. In order to confirm the existence of a subject, a certification body that exists geographically near the subject and can confirm the existence of the subject is in an advantageous position, difficult. Also, in case of a problem, the competent court is limited to one place. In addition, there are problems such as the absence of a standard competitive environment for conducting electronic trade procedures.

As one of the ways to overcome this, there is a method called Root CA. The root CA is a method in which a specific certification authority becomes the root and authenticates other certification authorities. However, from an international point of view, there is no uniformly agreed rule regarding electronic signatures, and the framework for electronically conducting all trade transactions having a special aspect of international electronic commerce is in a situation that has not yet been established.

The present invention is an electronic trade transaction that executes the cargo information initial registration processing of FIG. 15 showing the processing of FIG. 11 in detail, the rights transfer registration processing of FIG. 18, and the cargo information database closing processing for the termination of the rights transfer of FIG. A computer-readable storage medium on which a program is recorded is provided. The storage medium storing the electronic trade transaction program includes a removable portable storage medium such as a CD-ROM or a floppy disk, a storage device of a program provider who provides the program by line, and a RAM or hard drive of a processing device in which the program is installed. A memory device such as a disk. The electronic trade transaction program provided by this storage medium is loaded into the electronic trade transaction server 10 of FIG. 3 and executed on its main memory.

In addition, the present invention can provide a storage medium storing the client processing program for the transportation company of FIG. 21, the storage medium storing the client processing program for the seller of FIG. 22, and the storage medium storing the buyer client processing program of FIG. and each storage medium is loaded into the apparatus of each of the client 18 for the transportation company, the client 14 for the seller, and the client 16 for the buyer in FIG. 3, and is executed on its main memory.

Also, in the actual electronic trade transaction system shown in Fig. 2, the bill of lading banking system 20 and the letter of credit issuing bank system 24 participate as users receiving the service, and this bill of lading banking system 20 ) and letter of credit issuance bank system 24 functions as a buyer and a seller, so that the functions of both the seller client 14 and the buyer client 16 shown in FIG. 3 are installed. Also, for each of the seller and the buyer, depending on the transaction situation, they become a buyer or a seller on the contrary. As each client, similarly to the bank system side, the seller client 14 and buyer client 16 shown in FIG. 4 . It is preferable to provide both processing functions.

In addition, although the above embodiment has been described by taking an electronic trade transaction as an example, the present invention is not limited thereto, and in the case of performing a transaction of goods by electronic signature using a public key certificate issued by each certification authority, Similarly, the same structure as the electronic trade transaction system of the present invention can be applied. Further, the present invention is not limited to the above-described embodiments, but includes appropriate modifications without impairing the purpose and advantages thereof. In addition, the present invention is not limited by the numerical values shown in the above-described examples.

As described above, according to the present invention, according to the present invention, each person using a public key certificate for real transactions registers their respective public key certificates in the database of an electronic trade transaction service institution that has secured security, and as long as the public key certificate is registered, electronic The signature can be verified, and as a result, it becomes possible to safely conduct electronic trade transactions using a public key certificate issued by any certification authority without presupposing the existence of a root CA.

In addition, according to the present invention, the trade transaction is completely digitalized and the right of cargo is secured at high speed and safely by making the transfer of cargo rights electronically and with legal effect without electronicizing the current bill of lading. It can transfer from seller to buyer, and this electronicization can achieve efficiency of trade procedure.

The present invention provides an electronic trade transaction server for building a business model of electronic trade transaction that electronically digitizes cargo ownership without electronic billing of lading, and transfers this cargo ownership with a legal effect to achieve efficiency in trade procedures; It aims to provide a client for a seller, a client for a buyer and an electronic trade transaction method.

In addition, the present invention is based on the existing legal structure in a situation where the legal maintenance regarding electronic signatures is incomplete, and to establish a business model of electronic trade transactions that realizes safe international trade transactions using electronic networks by electronic signatures. An object of the present invention is to provide an electronic trade transaction server, a client for sellers, a client for buyers, and an electronic trade transaction method for

The main points of the business model of electronic trade transaction constructed by the present invention are the following three.

(1) Conduct electronic trade transactions by separate contracts.

(2) In the verification of the electronic signature, the exchange of the public key certificate in advance and the user registration information are used.

(3) Without using the bill of lading or the electronic bill of lading which is an electronic bill of lading, based on the legal method of "Transfer of title by instruction (map; 指圖)", the ownership of goods is transferred electronically.

These three points will be described in more detail as follows.

(separate contract)

In order to carry out the electronic trade transaction procedure with legal binding force, the following three contractual relationships are established in addition to the previous working contract.

(1) Certificate Authority Agreement (CA Agreement)

A contract for the issuance and use of a public key certificate required for verification of electronic signatures, respectively, between a trading party (exporter, importer, bank, insurance company, transport company, etc.) and a certification body.

(2) Electronic Trade Service Agency Agreement

It is a service contract that manages the transfer and registration of cargo information and cargo ownership information on a specific cargo subject to trade transaction in the database of an electronic trade transaction service institution. fastened between the tubes. Also, since the electronic trade transaction service institution functions as a Repository Service Provider (RSP), this contract is also referred to as an RSP contract.

(3) Data Exchange Agreement (IA Agreement: Interchange Agreement)

An electronic trade procedure involving registration in a database of public key certificates and cargo ownership provided by two services based on a Certificate Authority Agreement and an Electronic Trade Transaction Service Agency Agreement for trade transactions, hitherto conducted in writing, called bills of lading. (Transfer of ownership of goods) is a contract that gives rise to legal binding force, and is concluded between the trading parties with whom they have a direct transaction relationship.

(Verification of electronic signature)

The structure of the following 4 items is introduced.

(1) When a data exchange contract is concluded, a public key certificate issued by an arbitrary certification authority selected by the user is exchanged. In the case of not exchanging at the time of the contract, set the procedure for safe exchange at a later date, and exchange it at a later date.

(2) If the electronic signature can be verified using the public key certificate exchanged in the data exchange contract, the effect that the registrant of the electronic signature key is legally bound to the content of the transmission has occurred, or the transmission It is mutually agreed that the creation of the content is registered in the public key certificate and presumed to be signed.

(3) In order not to cause legal binding by verification of the public key certificate due to loss or compromise of the signing key, contact the e-trade transaction service institution to revoke the public key certificate registered in the user registration database. to be registered.

(4) In the data exchange contract, when the public key certificate is in an unregistered state at the time of verification of the electronic signature, it is agreed not to effect attribution or presumptive effect.

By introducing this structure, trading parties can obtain public key certificates using available nearby national certification authorities and use them for electronic signatures of electronic trade transactions.

(Transfer of ownership of cargo by direction)

The present invention is characterized in that, without using an electronic bill of lading, the current right holder of cargo ownership transfers the right electronically by giving an instruction to the occupant of the cargo (transportation company). However, since the present transportation company does not have an electronic service organization that receives and manages cargo ownership transfer instructions, the present invention is an electronic trade transaction service organization (repository service provider (RSP)) establishes, the electronic trade transaction service organization acquires the authority of representation from the transportation company, and transfers the cargo ownership registered in the database according to the instructions of the cargo owner. In this way, in order for the electronic trade service organization to replace the transport company's procedure, the electronic trade service organization acquires two of the passive authority and the active agent authority by contract from the transportation company in advance. The right of proxy is the right of the transport company to receive transfer instructions from the cargo owner. In addition, the right of active representation is the right to obtain approval from the transferee for the transfer instruction received from the cargo owner.

In the present invention, three "rights to possess", "right to possess", and "other rights" are assumed as the right of cargo. The right to occupy is defined as an access right in the present invention. This access right is the right to occupy the cargo and the right to change the registration of the database of the present invention. And the person who has the right of access is called the person with the right of access, and when the person with the right of access is changed, the occupant (a person who indirectly occupies the cargo) is also changed. In the electronic trade transaction of the present invention, the act of delivering the bill of lading in the conventional trade transaction is replaced by changing the right of access. Also, since the person occupying the cargo is not necessarily the owner, in the present invention, a data item called the owner is provided for the right to own the cargo. In addition, other rights are cargo incidental rights such as pledges or mortgages on the cargo.

In order to realize a business model of electronic trade transaction according to the above structure, the present invention provides an electronic trade transaction server, a client for sellers, a client for buyers, and an electronic trade transaction method.

The present invention provides an electronic trade transaction server installed in a core electronic trade transaction service institution, the electronic trade transaction server comprising a user registration processing unit, a transfer registration processing unit 34 and a verification processing unit . The user registration processing unit is, at the request of the trading parties, including sellers, buyers, and transport companies (shipping companies, airline companies, truck companies, railroad companies, etc.), a certification body in which each party has jurisdiction over them. Register the user registration information including the public key certificate obtained from the database. The transfer registration processing unit, based on the change registration request of the party with the digital signature and public key certificate attached, changes the access right holder of the cargo information 42 registered in the database and the cargo owner to another party at the time of transaction initiation. . The verification processing unit verifies that the digital signature attached to the change registration request has been created by the private key as a pair of public key certificates registered in the database, and also obtains the consent of the other party, thereby establishing a legally binding transfer registration. According to the electronic trade transaction server of the present invention, each public key certificate is registered in the database of an electronic trade transaction service institution that has secured security between those that use the public key certificate for real transactions, and the public key certificate is registered. As far as possible, it should be possible to verify the electronic signature. For this reason, it is possible to safely conduct electronic trade transactions using a public key certificate issued by any certification authority without the premise of the existence of a root CA.

Here, the transfer registration processing unit initially registers cargo information having the cargo owner as the seller in the database based on an initial registration request attached with a digital signature and a public key certificate from a transportation company client. Next, on the basis of the change registration request attached with the digital signature and public key certificate from the seller's client, the freight rights are changed to the buyer. Finally, on the basis of a closure request with a digital signature and public key certificate from the buyer client, the registration of the cargo information is closed to prevent the change of the cargo owner. In this case, the verification processing unit 36 verifies that the digital signature attached to each request is created by the private key that is a pair of public key certificates registered in the database 38, and obtains the consent of the other party, thereby increasing legal binding force. establish a previous registration with The user registration processing unit creates user registration information including the user ID of the trading party, the user registration date, the registration expiration date, the public key certificate, and user information, and registers it in the database. In addition, the user registration processing unit sets and registers the public key certificate revocation information in the user registration information at the request from the trading party, and changes it to the non-registration state, so as not to establish a legally binding previous registration by the verification processing unit. .

Freight information registered in the electronic trade server consists of fixed information and update information, and the fixed information includes cargo information ID, cargo information hash value, cargo information registration date and time, and cargo information, and updated information is accessed It includes information on the title holder, information on the owner of the cargo, information on the rights of the cargo unit, and the registration date and time of the change of the cargo information. In addition, the request message from the trading party has a message structure including the sender ID, the cargo information ID, the instruction to the server, the next owner ID, the cargo information, and a digital signature. The user registration processing unit of the electronic trade server also registers user registration data of an intermediate party such as a bank interposed between the seller and the buyer in the database. In actual trade transactions, intermediaries such as a plurality of banks intervene between a seller who becomes an exporter and a buyer who becomes an importer. For this reason, the transfer registration processing unit initially registers the cargo information based on the initial registration request with the digital signature and public key certificate attached from the transport company client, and then attaches the digital signature and public key certificate from the seller client. Based on one change registration request, the accessor and the cargo owner are changed to an intermediate party, and then, based on the change registration request attached with a digital signature and public key certificate from the intermediate party, the accessor and the cargo owner are changed to another intermediate party. Or change to buyer, and finally, on the basis of a closure request with a digital signature and public key certificate from the buyer's client, the registration of cargo information is closed to prevent the change of cargo rights. Even in this case, the verification processing unit verifies that the digital signature attached to the request has been created by the private key as a pair of public key certificates registered in the database, and obtains the consent of the other party, thereby establishing a legally binding transfer registration. . Intermediary banks in electronic trade transactions are, for example, the purchasing bank of a bill of lading that has a foreign draft contract with the seller, and/or the issuing bank of a letter of credit with the buyer. When the former registration processing unit of the electronic trade transaction server closes the registration of cargo information and prohibits the change of the owner of the cargo, it notifies the client for the transportation company of the closure of the database registration of the cargo information, and the cargo to the current owner of the cargo to direct the guidance of

The present invention provides a client for a transportation company for use in a business model of an electronic trade transaction. A client for a transportation company includes a user registration requesting unit that requests the electronic trade transaction server to register a database of user registration information including a public key certificate obtained from a certification authority having jurisdiction over it, and a digital signature and public key for cargo information.
