Description

Contract authenticating system using certification of contractor in mobile configuration and contractor authenticating method

The present invention authenticates the information of the contracting party when receiving the information of the contracting party from the user and applying for the contract authentication, and if the authentication is successful, issuing an authentication code and sending an SMS to the contracting party to authenticate the real name and identity of the contractor. A contract authentication system and a contract authentication method thereof.

A normal contract is based on the contents of the contract, the name of the contractor, the seal of the contractor, or the signature. Among them, the contractor's name and the seal or signature of the contractor guarantee the authenticity of the contracting party. And sincerity is proof that the contractor has stamped or signed at his or her will to commit to the faithful implementation of the contract.

Nowadays, contracts related to relatively simple and universal rights have tended to use simple signatures rather than cumbersome seals. However, in the case of signature, a third party can sign by stealing the contractor's identity. In addition, if the signature is stolen, there is a problem that it is difficult to determine whether the signature of the actual contractor or the counterfeit signature of a third party.

Therefore, the seal is usually used in the case of a contract with a significant contract, and in the case of a seal, a seal certificate is attached to guarantee the authenticity of the contract. However, in the case of the seal also a lot of cases of forgery or theft of the coating occurs. The same is true for an agent contract, such as an unauthorized agent signing a contract. The contract that can maximize the authenticity is a costly and time-consuming inconvenience despite attaching a seal certificate, and also has the problem of counterfeiting or theft.

The present invention is to solve the above-mentioned problems, when receiving the contract authentication application from the applicant, and extracts the information of the individual contractor to authenticate the mobile communication terminal of the real name and his name, and if the authentication of the power supply unique authentication code It is intended to provide a contract authentication service that authenticates the contractor himself / herself to the contractor whose certification code is specified by sending SMS to each contractor after granting.

According to the contract authentication system using the contractor authentication of the present invention for achieving the above object, SMS authentication to the contractor in real time after authenticating the contractor information to prove whether the contractor is listed in the contract on the wired or wireless network A contract authentication system comprising: means for registering an applicant and storing membership registration information; Means for comparing the applicant's access information and membership registration information and receiving a contract authentication application including at least one contractor's information from the applicant and storing it in a DB when authentication is successful; Means for requesting authentication of individual contractor information extracted from the contract authentication application and receiving an authentication result; Means for generating a unique authentication code and storing it in a DB if the authentication result of each individual contractor is successful; Means for responding to the applicant the results of the processing of the contract certification application; And a contract authentication server comprising means for SMS sending the authentication code to the individual contractor using the individual contractor's mobile phone number extracted from the contract authentication application, thereby realizing the authentication code that the contractor wishes to prove himself. Characterized in that issued.

Preferably, the contract authentication server, means for performing online real name authentication through an external credit information company using the name and social security number extracted from the contractor information; And means for performing online authentication of whether or not the user is registered through an external mobile communication company by using the name, social security number, and mobile phone number extracted from the contractor information.

Further, the contract authentication server is to receive the contract authentication request from the applicant using a communication method including a homepage, a wireless application protocol (WAP), an auto response service (ARS), a short message service (SMS), or an email. It features.

Preferably, the contract authentication server further comprises means for sending an SMS asking whether to agree to the applicant's contract authentication application using the individual contractor's mobile phone number if the authentication result of all the contractors is successful, When the individual contractor responds to the SMS, the authentication code is generated.

Further, the contract authentication server is characterized in that the agreement of the contractor by receiving a specific character string or the authentication password previously registered by the contractor in response to the SMS from the contractor mobile communication terminal.

Furthermore, if the contractor agrees, the contract authentication server examines the GPS location or the LBS location based on the mobile communication network base station for the mobile communication terminals of all contractors, and sets the service provider using the transmitted coordinates. When within the error distance of, characterized in that to allow the generation of the authentication code.

On the other hand, according to the contract authentication method using the contractor authentication of the present invention, after authenticating the contractor information to prove whether the contractor is listed in the contract on the wired or wireless network, the contract authentication of the contract authentication server for SMS transmission of the authentication code to the contractor in real time A method comprising: (S21) contract authentication server registering an applicant and storing membership registration information; (S22) when the authentication is successful by comparing the applicant's access information and membership registration information, receiving a contract authentication request including at least one contractor information from the applicant and storing the contract authentication application in a DB; (S23) requesting authentication of individual contractor information extracted from the contract authentication application and receiving an authentication result; (S25) if the authentication result of all the individual contractors is successful, generating a unique authentication code and storing it in a DB; (S26) responding to the applicant the processing result of the contract certification application; And (S27) sending an SMS to the individual contractor using the mobile telephone number of the individual contractor extracted from the contract certification application, and sending the verification code to the individual contractor in real time. It features.

The contract authentication system using the contractor authentication and the contract authentication method according to the present invention perform user authentication for all contractors involved in the contract for the contract authentication application of the applicant, and if authentication is successful, issue a real-time authentication code to issue the authentication code. DE certifies the contractual details and the contractor of the contract.

In addition, if an important contract or field is considered important, whether the contracting parties exist at the same location can be examined and if they exist at the same location, an authentication code can be issued to guarantee the identity and authenticity of the contracting parties.

<1. System configuration>

1.1 System Overview

1 to 3 show a schematic configuration of the contract authentication system 1 according to the present invention. 1 illustrates a schematic configuration of a contract authentication system 1 according to the present invention, and FIG. 2 illustrates a method for transmitting a contract authentication request from a user terminal 3 to a contract authentication server 2 according to an embodiment of the present invention. 3 illustrates a platform environment, and FIG. 3 illustrates a data flow of the contract authentication server 2 according to an embodiment of the present invention.

Referring to Figure 1, the contract authentication system 1 according to the present invention is applied to the contract authentication application from the user terminal 3, the applicant's user terminal 3, which the applicant and the contractor use for communication with the contract authentication server (2) After receiving and authenticating the contractor, if the authentication is successful, the authentication request of the user is received from the contract authentication server 2 and the contract authentication server 2, which sends an SMS to the contractor's user terminal 3, and the authentication is performed. It is configured to include an authentication service server.

The contract authentication system 1 of the present invention authenticates the contractor's own person when receiving the contract authentication application from the applicant (individual, corporation, organization, etc.), and if successful, provides a contract authentication service for issuing a unique authentication code to the contractor. to provide. This authentication code certifies that the signature or seal corresponding to the names of all listed contractors listed in the contract is a true statement of intent.

Referring to FIG. 2, according to an embodiment of the present invention, the applicant transmits a "contract authentication request" requesting the contractor's authentication to the contract authentication server 2 using the user terminal 3.

In the present invention, the contract authentication server 2 may receive a contract authentication request from the applicant through various communication methods. The communication methods are a) web method, b) WAP method, c) ARS method, d) SMS method, and e) email method according to the communication platform.

A) The web method requires the applicant's user terminal 3 to have a homepage access function capable of accessing the Internet using a wired or wireless network, and the web server 201 of the contract authentication server 2 is provided from the applicant who accesses the homepage. Receive a contract certification application.

B) The WAP method requires the applicant's user terminal 3 to have a wireless Internet access function capable of wireless Internet access using a mobile communication network, and the WAP server 202 of the contract authentication server 2 accesses a WAP page. A contract authentication application is transmitted from an applicant's mobile communication terminal.

C) The ARS method requires the applicant's user terminal 3 to have a dial-up function capable of dial-up using a wired or wireless telephone network, and the ARS server 203 of the contract authentication server 2 provides an automatic guide voice. Receive the contract authentication request from the applicant who connected the call.

D) The SMS method requires the applicant's user terminal 3 to have an SMS transmission function capable of SMS transmission using a mobile communication network, and the SMS server 204 of the contract authentication server 2 is configured from the applicant's mobile communication terminal. Receive SMS of contract certification application.

ㅁ) In the mail method, the user's terminal 3 of the applicant is required to have a mail sending function capable of sending mail using a wired or wireless Internet network, and the mail server 205 of the contract authentication server 2 receives the mail of the contract authentication application from the applicant. Receive the.

Here, in the SMS method and the mail method, it is preferable that a document form template for creating a contract authentication application is stored in the user terminal 3 of the applicant.

Referring to FIG. 3, the contract authentication server 2 receives a contract authentication request from the applicant's user terminal 3 according to the platform environment of FIG. 2 described above (①).

Preferably, the applicant of the present invention may limit the eligibility for the application only to the contractor, or may be a third party (eg, broker, stakeholder, etc.).

Further, the contract certification application includes all the contractors' information (eg, name, social security number, address, mobile phone number, etc.) for user authentication. In addition, it may further include contract information (eg, contract name, contract date and time) and applicant information. In addition, in the case of an agent contract, it may be required to include only the agent information or to include both the information of the agent and the agent.

Furthermore, a picture file of the contract can be attached as an attachment to the contract certification application. The photo file of the contract is to prove the contents of the contract.

The contract authentication server 2 extracts the contractor's information from the received contract authentication application and applies for user authentication to the authentication service server 4 (②). User authentication may further include applicant authentication, and the applicant information is extracted from the sender information of the contract certification application or from the contents of the contract certification application.

The authentication service server 4 is a server for performing user authentication, for example, a server of a credit information company or a mobile communication company server. The user authentication of the present invention performs either real name authentication or mobile communication service subscriber authentication or both.

Real name authentication is to authenticate the real name using the user's name and social security number. And the mobile communication service subscriber authentication is to authenticate whether the user is a mobile communication service subscriber using the user name, social security number, and mobile phone number. The mobile communication service subscriber authentication proves that the mobile communication terminal is a terminal subscribed to by the contractor when the authentication code of the present invention is transmitted to the contractor's mobile communication terminal.

The contract authentication server 2 receives the contractor authentication result or the applicant and contractor authentication results from the authentication service server 4 (③). If only one of the user authentication results in the service policy fails, the failure can be notified and the contract authentication can be stopped.

If the authentication of all the users is successful, the contract authentication server 2 generates an authentication code and responds in real time to the application result including the authentication code to the user terminal 3 of the applicant (6). Then, the authentication code is transmitted to the user terminal 3 of the individual contractor by SMS (⑦). Here, the authentication code may be a different code for each contractor or may issue the same code to everyone. If different authentication codes are issued, the security of the individual contractor's authentication codes is enhanced. And if the same code is issued, it is possible to collectively query the contract information, applicant and contractor information when searching using the authentication code instead of weakening the security.

On the other hand, if the user authentication is successful (③), in the present invention, as an optional addition, the consent SMS requesting whether or not to agree to the applicant's contract authentication application to inform the contractor that the applicant performed the contract authentication application to the contractors. (④). In case of receiving agreement confirmation from all contractors (⑤), respond to each applicant's results and send SMS to the applicant and contractor (⑥, ⑦). Here, the agreement confirmation of the contractor may be input of a specific button of the user terminal 3, input of a specific character string of the message content, or input of a password previously set in the contract authentication server 2 by the contractor.

And when sending the consent SMS, it is also possible to issue a verification code by checking whether the agreement response SMS of the same location. This is to perform the security certification of the enhanced requirements, and when receiving the agreement of the power supply for a predetermined time from the contractor, the GPS coordinates of the user terminal 3 of the contractor or coordinates based on the mobile carrier base station (location tracking service, LBS) If it is determined that the service provider is within a predetermined error range set by the service provider, the authentication code is allowed to be generated. For example, in consideration of the efficiency of the system, the service provider registers the GPS coordinates with a radius of 10 m, and sets the error range to the jurisdiction of the same base station for the LBS. Since there are more general terminals than GPS-embedded terminals, it is preferable to determine whether all users and contractors are in the same location using location coordinates based on a mobile communication company base station. Of course, whether the same location survey associated with the consent SMS can be changed at any time according to the service policy. For example, this can be done before receiving an application for contract certification from the applicant and performing contractor certification.

Subsequently, the applicant and the contractor who issued the verification code SMS authenticate the authenticity of the contract by entering the contract by entering the verification code in the contract. And when a problem occurs in the intention of the contractor after the contract, it is possible to claim the authenticity of the contract by requesting the generation history information of the authentication code to the contract authentication server (3). This is because the contract authentication server 3 stores the date and time history information related to the applicant's certification application facts, user authentication results, agreement results of all contractors, and the like.

As another example of the present invention, it is also possible for an applicant to design and register an authentication procedure in advance, and then transmit a contract authentication application. This can be used more effectively if the contract's authentication options are complex and there are multiple contractors. For example, when you want to register and authenticate contract photos or scan information in advance, when all the contractors require consent from all the contractors, but want to receive the same location service for only some contractors (e.g., only the agent except yourself) Users can design and apply various authentication options.

First, since the applicant has already registered the detailed information corresponding to the contract code, when the contract authentication application is transmitted to the contract authentication server 2, the user information and the contractor information can be substituted by only inputting the contract code.

First, the applicant registers the contents of the contract, the authentication procedure, and the like in advance in the contract authentication server 2. The contract authentication server 2 registers the mobile communication terminal telephone numbers of all parties (including the owner and the agent) and stores them in the DB. And the applicant issues a unique contract code corresponding to the contract information entered.

After the contract code is issued, upon receiving the contract authentication request including the contract code from the applicant, authentication is performed using user information extracted from the contract information corresponding to the contract code, and if successful, all users of the contractor SMS the authentication code to the terminal (3). Of course, it is also possible to selectively add a technique for sending a consent SMS.

1.2 Structure of Contract Authentication Server

4 shows the internal structure of the contract authentication server 3 according to an embodiment of the present invention.

The contract authentication server 3 according to an embodiment of the present invention is a contract authentication application means 22 for receiving a contract authentication application from an applicant, and user authentication means for extracting contractor information included in the contract authentication application to authenticate individual contractors. 23, authentication code generation means 25 for generating an authentication code if the user authentication is successful, the application result response means 26 for responding the application result to the applicant, and the SMS of the authentication code as a user of the individual contractor; It comprises a verification code SMS transmission means 27 for sending to the terminal (3).

Preferably, as a component that can be optionally added to the above components (indicated by dashed lines in FIG. 4), the member management means 21 for receiving the membership request from the user and processing the membership to store membership information, user authentication If this is successful, the consent SMS transmission means 24 which inquires whether to accept the contract authentication application of the applicant by the contractor and agrees and receives the response, and the authentication code retrieval means which receives the authentication code retrieval request from the user and provides the processing history ( 28) may be further included.

Detailed functions and operations of the individual components 21 to 28 constituting the contract authentication server 2 will be described through the contract authentication method described below.

<2. Method composition>

A contract authentication method for authenticating a contract using SMS of a mobile communication terminal according to an embodiment of the present invention can be preferably realized through the construction of the contract authentication method system 1 described above.

2. 1 day Example  Contract authentication method

Figure 5 shows the overall sequence of the contract authentication method according to an embodiment of the present invention.

The applicant connects to the contract authentication server 2 using his user terminal 3, and enters contractor information (eg, name, social security number, mobile phone number, etc.) to transmit the contract authentication request. If the contractor includes an agent, the agent information is required and additional information may be required.

The contract authentication application means 22 of the contract authentication server 2 receives the contract authentication application of the applicant and stores it in the DB (S22). As shown in FIG. 2, the transmission path of the contract authentication application may be various communication methods such as a web method, a WAP method, an ARS method, an SMS method, or an email method, depending on the platform environment.

When the contract authentication application is received, the user authentication means 23 extracts user information from the received contract authentication application and performs authentication (S23). Here, the user to be authenticated may necessarily include contractor authentication, and optionally, applicant authentication may be further included. And the applicant information may be extracted from the sender information or application details of the contract certification application. User authentication includes real name authentication by transmitting user information to a server of an external credit information company and authenticating user subscription to a mobile communication service by transmitting user information to an external mobile carrier server.

If the authentication result is successful for all the users, the authentication code generating means 25 generates an authentication code and stores it in the DB (S25). The authentication code has already described that each user can issue a different code.

After generating the authentication code, the application result response means 26 responds to the processing result to the user terminal 3 of the applicant who sent the contract authentication application in step S22 (S26). The processing result may include an authentication code.

Thereafter, the authentication code SMS transmission means 27 transmits an SMS with the content of the authentication code issued to the user terminal 3 of the individual contractor (S27). The contractor checks the authentication code and writes it in the contract to complete the contract.

FIG. 6 illustrates a sequence of additional steps that may optionally be added to the contract authentication method of FIG. 5.

In the present invention, it is possible to provide a contract authentication service for member subscribers. For example, the service is provided only when the applicant is a member subscriber, or when the applicant and the contractor are all members.

Accordingly, the contract authentication server 2 member management means 21 receives a member registration request from a user, provides a member registration page, registers member information, and stores the member information in a DB (S21). And, if the applicant is a member subscriber can perform the step (S22) receiving the contract authentication request. In this case, the contract authentication server 2 may compare the user terminal 3 of the applicant and the password input by the applicant with preset member information to determine whether to register.

In the user authentication step (S23), real name authentication, mobile communication service subscriber identity authentication, and member subscriber authentication may be further performed.

If the authentication is successful, the consent SMS transmission means 24 informs the contractor that all applicants now apply for contract authentication and sends a consent SMS asking whether to agree to it and receives a consent response SMS (S24). If the consent response is transmitted with the password set by the contractor, of course, the authenticity of the user can be secured. In other words, the password responded by the contractor with the intention of consent may be regarded as a more certain intention of consent because it is a unique password that only the contractor himself knows. Further, in the consent SMS step (S24), as described above, it is possible to determine whether or not the location is the same by comparing the location of sending the response SMS of the contractor.

If all the contractors agree or if it is determined to be the same location together with the power agreement, the authentication code generation step (S25) is performed to guide the applicant to the application result (S25) and at the same time send an SMS to the user terminal of the individual contractor. (S26).

If the same location service used in the present invention requires the same location between the contractors, the present invention can be applied to a variety of cases as well as when creating an important contract (eg real estate sales). For example, if a patient who smiles at the medical insurance card is referred to a hospital instead of a social security number, the hospital becomes an applicant and the hospital and the patient become contractors to use the same location service using the service of the present invention. This allows you to prove that you have visited the hospital. Another example is insurance coverage. When an insurance broker makes an insurance contract with an insurer or insured, the insurance broker becomes an applicant and the insurer and the insured become contractors. In addition, by verifying the same location for insurance agents, insurers and insureds, write the issued authentication code in the insurance contract, and then prepare the insurance contract to guarantee not only the authenticity but also the field of the contracting party.

In addition, the authentication code search means 28 of the contract authentication server 2 may provide the history information of the contract authentication application to a user who accesses the homepage through a wired or wireless network. By requesting the user to request the inquiry can be provided by requesting the applicant's contract certification application, contract photos, user authentication results, user consent results, the user's same location information from the DB. In particular, if the location information of the user and the contractor are judged to be in the same region, it is difficult for the parties to make invalid claims, signatures or seal claims in the contract. Such a search service may be provided in real time through the WAP server 202 and the ARS server 203 as well as the web server 201 of the contract authentication server 3.

On the other hand, as described above, in the present invention, when the contract information is registered in advance by the applicant, the contract code is issued, and the contract certification application including the contract code is received from the applicant to generate the authentication code. When the contract authentication server 2 registers the applicant and user information in advance, the contract authentication server 2 issues a contract code to the applicant. Upon receiving the applicant's contract certification application, the user stores the pre-stored information corresponding to the contract code, performs user authentication, consent SMS transmission, and issues an authentication code to the contractor.

7 and 8 illustrate screens in real estate sales contract authentication using a mobile communication terminal.

Referring to FIG. 7, the real estate agent receives an initial screen when accessing the wireless Internet using his user terminal 3, inputs the buyer and seller information, and transmits the information to the contract authentication server 2. If the user authentication is successful, a result screen is displayed in which a part of the authentication code issued to the individual contractor is displayed.

Referring to FIG. 8, the seller and the buyer corresponding to the contractor of the real estate contract receive the verification code SMS, and the other party's name is transmitted with the verification code to the SMS. The seller and the buyer then enter into their contract with their authorization code.
