Description

Method of providing electronic registration service based on virtual authentication code {METHOD AND PROGRAM FOR PROVIDING ELECTRONIC REGISTRATION SERVICE BASED ON VIRTUAL AUTHENTICATION CODE}

The present invention relates to a method and apparatus for providing an electronic registration service based on a virtual authentication code. In more detail, it relates to a method and system for providing an electronic registration service that generates a user authentication code that is generated not to be duplicated at each point in time, searches user information based on this, and conducts a real estate transaction.

The accredited certificate system, which was used to authenticate user information in various fields, including online financial transactions, was abolished as of December 10, 2020. In the meantime, the accredited certificate required repeated renewal, and many users felt inconvenience due to the inconvenience of forcing the installation of a security program during the authentication process. In addition, when the public certificate is stored on the user's device, security vulnerabilities are exposed in the storage method, and above all, the system has been criticized for transferring the security responsibility to the user. Nevertheless, many users had no choice but to use public certificates for the security of personal information despite the inconvenience and vulnerability exposed.

On the other hand, code form data is used in many areas. In addition to card numbers and account numbers used for payment, IPIN numbers for user identification, resident registration numbers, etc. are code-type data. OTP (One Time Password) is a code-type data that is frequently used in the recent financial transaction process. However, in the case of OTP, although the code is changed every time and generated, it is difficult to apply to various areas because a login procedure is required to determine the algorithm assigned to the user. Specifically, in order to use OTP, it is impossible to recognize the serial number without omitting the log-in process because it is necessary to log in with an ID and password, register a number, and then synchronize the time. Therefore, OPT only plays a role as a secondary means in authenticating users.

That is, as a user authentication means to replace the public certificate, there is no suitable method for generating code data that can immediately authenticate the user based on the security code that can authenticate the user according to the user's request. the current situation.

2 is a block diagram illustrating a method of providing an electronic registration service based on a virtual authentication code according to an embodiment of the present invention.

As shown in FIG. 1 , the electronic registration service system replacing the OTAC-based accredited certificate consists of a plurality of user terminals 10 , and a real estate broker terminal 20 and a server 30 .

In order to help the understanding of the present invention, the user terminal will be described by dividing the registration right holder terminal 11 and the registration obligation terminal 12. In addition, an embodiment of the present invention will be described with an example of real estate transaction through a server.

First, referring to FIGS. 1 and 2 , the registration right person or the person responsible for registration requests the server to generate an entitlement number (S310).

In the present specification, the user terminal 10 is a mobile terminal of a user who wishes to perform real estate-related administrative procedures and real estate transactions. The user terminal 10 may have a built-in or installed dedicated program or dedicated application (hereinafter, virtual authentication code-based electronic registration dedicated program) for the electronic registration service replacing the OTAC-based accredited certificate.

In one embodiment of the present invention, the electronic registration service dedicated program serves to register information about the user in the server (30). That is, the user installs the electronic registration service dedicated program in the user terminal, or receives user information from the user during the membership registration and/or login process in the process of executing the electronic registration dedicated program, and sends the user information to the server 30 . Send and register

The server 30 serves to generate a 'qualification number' for real estate transaction execution by using the user information provided from the user terminal 10 . That is, the server 30 generates an entitlement number by using all or part of the user information provided from the user terminal 10, including the entitlement number generation function. For example, the server 30 may generate an entitlement number by using the resident registration number included in the user information as seed data of the entitlement number generating function.

More specifically, when the seller, the person responsible for registration, accesses the server of the Internet registry through a terminal, or executes an application and/or program provided from the Internet registry and requests issuance of a qualification number for registration application, the server 30 requests In response, a qualification number for registration application is issued to the person responsible for registration. On the other hand, the server 30 issues a qualification number for registration application to the registration right holder in response to a request for issuance of the qualification number for registration application of the purchaser, the registration right holder. That is, each of the qualification numbers for the registration right holder and the registration obligation person who conducts transactions with respect to the same real estate is generated and issued.

Meanwhile, according to an embodiment of the present invention, the server may generate an OTP (One Time Password) based on the time when the seller, the person responsible for registration, requests the creation of the qualification number, and may also generate the qualification number based on the OTP. Similarly, the OTP may be generated based on the time when the purchaser, the registration right person, requests the generation of the qualification number, and the qualification number may be generated based on the OTP.

In this case, the OTP may be characterized in that it is used when the server checks whether the entitlement number is normally generated. That is, according to an embodiment of the present invention, the entitlement number that is the virtual authentication code may be generated based on the time data when the server 30 is requested to generate the entitlement number from the user. At this time, the OTP generated based on the time data corresponds to the verification number.

Referring to FIG. 2 , the server generates a virtual security code, which is a one-time code of a specific number of digits, by the virtual security code generating module according to a user's request (S310).

In this case, the virtual security code may be generated according to the OTP method as a verification means for authenticating the user in the server. That is, based on the time of requesting the issuance of each user's entitlement number for registration application, an OTP for each user is generated.

At this time, in an embodiment of the present invention, the entitlement number generation module of the server may generate an entitlement number corresponding to the user based on the virtual security code (OTP) and information related to the user who requested the entitlement number generation (S320). ). As described above, the user-related information is information about each user registered in the server, and may include a resident registration number, address, phone number, etc.

On the other hand, after generating the entitlement number, the server transmits the entitlement number to the user (S330). The user may use the qualification number to perform real estate administrative procedures through the server, and may be used for real estate transactions.

At this time, the virtual security code and the entitlement number are changed and generated for each unit count by the entitlement number generating module, and the unit count is set at a specific time interval, and is changed as the time interval elapses. Therefore, the qualification numbers of the registration right person and the registration duty person are generated with different values because they are changed and generated for each different unit count.

On the other hand, referring to FIG. 1, according to a typical real estate transaction method, the registration right holder and the registration duty person may provide each of the qualification numbers provided from the server to the real estate agent to execute the real estate transaction. Through this, the real estate agent can perform real estate transactions based on each qualification number provided without an authentication means such as an accredited certificate of each registration right holder and registration obligation.

On the other hand, referring to FIG. 1, when the real estate agent provides the respective qualification numbers of the registration right holder and the registration obligation to the server 30, the server 30 performs a verification process based on the corresponding qualification number and verification number. . In this case, the verification number means the above-described security code, OTP.

Specifically, based on each qualification number, information on the verification number is extracted, and then it is checked whether the corresponding qualification number is normally generated using the verification number. Meanwhile, in the above-described verification process, the server may verify the digital signature of the real estate agent to verify in advance whether the real estate agent corresponds to an agent having a legitimate authority of representation.

Meanwhile, referring to FIG. 3 , the server 30 includes a virtual verification number generation unit 310 and a virtual verification code generation unit 320 .

Verification number generator 310 serves to generate one or more detailed codes based on user data stored in the server in response to a request for generating a qualification number through the user terminal 10 .

The virtual authentication code generating function includes one or more detailed code generating functions. For example, when the virtual authentication code includes a plurality of detailed codes, the virtual authentication code generating function generates a plurality of detailed codes using a plurality of detailed code generating functions, and a detailed code combination for combining the plurality of detailed codes Create a virtual authentication code using a function.

In one embodiment, the server may use the serial number of the user terminal provided from the user terminal as one of the seed data of the virtual authentication code generating function. As a specific example, the virtual verification number generation unit 310 uses a combination serial number that combines the serial number of the user terminal and the serial number of the dedicated program using one detailed code generation function as seed data of each detailed code generation function. Generate each detail code. At this time, the virtual verification number generation unit 310 may generate each detailed code by using the time when the user's entitlement number generation is requested or the count value.

In one embodiment, the virtual verification number generator 310 may generate the first code and the second code, including the first function and the second function as the detailed code generation function. At this time, in order to increase security, the first function for generating the first code and the second function for generating the second code are included as detailed code generating functions, and data on the correlation between the first code and the second code is may not be included.

On the other hand, the verification number is a security code generated based on a specific verification number generation function, and is used to verify whether it is a normal virtual authentication code. The verification number generating function may generate a security code having a specific number of digits by using time data and a unique value for each user as a function value.

An example of the process of determining whether the virtual card number is normal by using the virtual security code is as follows. When the server 30 registers user information, the user terminal 10 receives a specific value (eg, a unique value of a chip in a smart card or a unique value of a smart phone in which an app card is installed) or authentication information about the user and receives a specific You can save it to your storage space. After the server 30 generates a virtual authentication code combined with a virtual security code and provides it to the user, when the virtual authentication code is provided again through the user or a real estate agent, the virtual authentication number verification means (not shown) is based on the detailed code Acquires time data in which a virtual authentication number is generated by using a method, extracts the unique value of a specific user terminal 10 stored therein, and generates a verification number with time data (eg, OTP (One-Time Password) function) is applied to calculate the virtual security code. And the server 30 determines whether the calculated virtual security code (ie, received virtual security code) matches the virtual security code (ie, generated virtual security code) calculated by the verification number generation function stored therein.

On the other hand, in one embodiment, when the virtual authentication code is generated as a combination according to a specific rule of the first code and the second code, the first code and the second code is each role for searching the storage location where user information is stored can be performed. For example, the first code sets a starting point of searching for a storage location, and the second code sets a search path from the starting point to the storage location according to a specific search method. That is, after the virtual authentication code normally generated for each unit count is provided from the server 30, the server 30 moves from the search start point corresponding to the first code along the search path corresponding to the second code to the user information is determined by the storage location of A specific method of searching a storage location based on the first code and the second code constituting the virtual authentication code will be described later.

The virtual authentication code generation unit 320 serves to generate a virtual authentication code, that is, an entitlement number by combining one or more detailed codes using a virtual authentication code generating function. In one embodiment, the virtual authentication code is generated by combining a plurality of detailed codes according to a specific rule. The virtual authentication code generation function includes a rule for combining a plurality of detailed codes (ie, a detailed code combining function). That is, the virtual authentication code generation unit 320 may combine one or more detailed codes using the detailed code combining function included in the virtual authentication code generating function.

Various methods may be applied as a method of generating one virtual authentication code by combining a plurality of detailed codes. As an example of the detailed code combination function, the virtual authentication code generation unit 320 may generate a virtual authentication code by alternately disposing an N-digit first code and an N-digit second code. Also, as another example, the detailed code combining function may be a function of combining the second code after the first code. As the number of detailed codes included in the virtual authentication code increases, various detailed code combining functions may be generated.

In addition, in one embodiment, when the virtual authentication code is generated by a combination according to a specific rule of the first code and the second code, the first code and the second code are matched to the user to search for a location where user information is stored Each can play a role. For example, the first code sets a starting point of searching for a storage location, and the second code sets a search path from the starting point to a storage location of the user information according to a specific search method.

That is, after the virtual authentication code (entitlement number) normally generated for each unit count is generated in the server 30, the server 30 moves from the search start point corresponding to the first code along the search path corresponding to the second code. A point is determined as a point connected to the user information storage area. A specific method of searching for a storage location of user information based on the first code and the second code constituting the virtual authentication code (entitlement number) will be described later.

As an embodiment of the method in which the virtual verification number generation unit 310 generates a detailed code (verification number), the virtual verification number generation unit 310 generates a new detailed code (verification number) for each unit count, and accordingly The server 30 generates a new virtual authentication code for each unit count. A newly generated virtual authentication code for each unit count is not duplicated. Specifically, the virtual verification number generation unit 210 is configured so that the newly generated virtual authentication code for each unit count is not duplicated for a specific user or a specific server for a predetermined period, and is not duplicated between users belonging to a specific group. can be set.

As a specific embodiment of preventing duplicate generation of virtual authentication codes, when generating N-digit first or second codes with M characters, the detailed code generating function included in the virtual authentication code generating function is MN codes can be generated as the first code or the second code, and each code is matched for each count from the initial time point at which the detailed code generation function is driven. For example, when the unit count is set to 1 second, different MN codes are matched every second from the time when the detailed code generating function is first driven. And, if the period using a specific detailed code generation function or the period of use of the server 30 is set to a time length shorter than the time length corresponding to the MN count (eg, MN seconds when 1 count is 1 second), the first The code or the second code is not duplicated during the use cycle. That is, when the count increases as time passes, when the user requests generation of a qualification number or virtual authentication code from the server 30 at a specific time, the server 30 matches the count corresponding to the specific time. The converted code value may be generated as the first code or the second code.

Specifically, if uppercase letters of the alphabet and numbers from 0 to 9 are used as characters that can be included in the code (that is, 36 characters are used), and 6 digits are allocated to the first code and the second code, respectively, the server (30 ) may provide 366 codes as the first code and the second code. In this case, the server 30 may provide the first code and the second code changed for each count by matching each code for each count.

As another specific embodiment for preventing the duplicate generation of the virtual authentication code, the function (ie, the first function or the second function) that periodically generates the first code or the second code is changed, or the first code and the second code Change the matching relationship of , so that a virtual authentication code different from the previous use cycle is generated. When the virtual authentication code is combined with the first code generated by the first function and the second code generated by the second function, when the first code generating function or the second code generating function is changed, the server 30 is As the order in which the first code or the second code appears is different from the previous use cycle, a virtual authentication code generation function that generates a virtual authentication code different from the previous cycle may be applied to the new use cycle. In addition, the server 30 prevents the same code as the virtual authentication code used in the previous use cycle from appearing as the virtual authentication code (= entitlement number) of each count in the new use cycle (that is, the first function generated according to the first function). The first function and the second function may be selected so that the matching relationship between the first code and the second code generated according to the second function is not included in the matching relationship included in the previous use period in all counts of the new use period). In other words, after the use cycle in which MN codes can be applied once has elapsed, the virtual authentication code overlaps with the previous use cycle through adjustment or renewal of the virtual authentication code generation function, that is, virtual authentication of a new use cycle in which no qualification number is generated. Code generation function can be applied.

Hereinafter, a method of authenticating a user based on the server's entitlement number and verification number will be described.

Referring to FIG. 3 , the server 30 includes a verification number extraction unit 330 , a storage location search unit 340 , a user information storage unit 350 , and a user information extraction unit 360 .

Here, the server 30 refers to a server (eg, an Internet registry server) that extracts user information connected to the virtual authentication code based on the virtual authentication code and performs real estate transactions with the user information.

The verification number extraction unit 320 serves to extract one or more verification numbers included in the virtual authentication code. In one embodiment, the verification number extraction unit 320 extracts only the OTP from the qualification number including the verification number.

In addition, in another embodiment, the verification number extraction unit 320 of the server 30 includes a detailed code combination function included in the virtual authentication code generation function. Accordingly, when the virtual authentication code includes a plurality of detailed codes, the verification number extraction unit 320 may extract a plurality of detailed codes from the virtual authentication code by applying the detailed code combining function.

For example, when the server 30 generates a virtual authentication code in which two detailed codes (ie, the first code and the second code) are combined at the time when the user requests the creation of the entitlement number, the detailed code extraction unit 320 ) can separate the first code and the second code by applying the detailed code combination function in the character array of the virtual authentication code.

The storage location search unit 340 serves to search the storage location of user information in the storage location search algorithm based on one or more extracted detailed codes. Here, the storage location search algorithm matches the virtual authentication code generation function used when generating the virtual authentication code. Various methods may be applied as a method for the storage location search unit 340 to search the user information storage location based on each detailed code. In order for the storage location search unit 340 to search for a storage location based on the plurality of detailed codes, a correlation may be included between the detailed codes.

When the virtual authentication code (entitlement number) is composed of the first code and the second code, in an embodiment having a correlation between the detailed codes, the storage location search unit 340 determines the search start point corresponding to the first code. It is determined, and a point moved along the search path corresponding to the second code from the search start point may be found as a storage location of the user authentication information. That is, the detailed code may include a first code for setting a starting point of the storage location search and a second code for setting a search path from the starting point to the storage location of the user authentication information according to a specific search method. can

In addition, in another embodiment, as the server 30 provides a new virtual authentication code for each unit count, the user sets the search start point and the search path based on the first code and the second code that are changed for each count. A storage location of information (ie, a location where user information is registered) can be searched.

Also, as another embodiment, the storage location search unit 340 may include a storage location search algorithm to find a storage location of the user's authentication information using a plurality of detailed codes having correlations. The storage location search algorithm is an algorithm that makes it possible to search for a storage location when each detailed code included in the virtual authentication code is applied, and generates a virtual authentication code used when the virtual authentication code generating device 200 generates a virtual authentication code. It matches the function.

For example, when the virtual authentication code includes a first code for determining a search start point of a storage location and a second code for suggesting a storage location direction from the search start point, the storage location search algorithm corresponds to the first code. When the direction corresponding to the second code is indicated at the point in question, it is an algorithm that adjusts so that a storage location matching the registration time of the user information is arranged at the corresponding location.

In addition, in another embodiment, the virtual verification number is to be used when checking whether the virtual authentication code transmitted from the user terminals 11 and 12 or the real estate agent terminal 20 in the server 30 is normally generated. can That is, the server 30 extracts the virtual verification number included in the virtual authentication code after receiving the virtual authentication code, and user information stored in the server 30 (eg, as user authentication information, resident registration number, address, phone number). number, etc.), it is checked whether the received virtual verification number is normally generated at the time of requesting the generation of the virtual verification code, and it is determined whether the virtual verification code is normal.

In addition, in one embodiment, the server 30 extracts the virtual verification code from the second code generated based on the virtual verification number, and then uses the virtual verification code generation function to input a count within a specific range from the count of receiving the virtual verification code. It is checked whether there is a value that matches the virtual verification code among the calculated OTP numbers. The server 30 applies the inverse function of the second function to the second code to obtain a virtual verification code value used for generating the second code, that is, an OTP value, and finds a count that yields the same value as the virtual verification code value.

Also, according to an embodiment, in the storage location search algorithm, a user identification (UID) may be assigned to each storage location. That is, each storage location may include a user identification (UID), which is a code value that can specify each. Specifically, the UID is a code value assigned to each storage location on a storage location search algorithm for an OTAC-based real estate transaction service used by a user, and is a code value indicating a count in which user information of a specific user is registered. That is, the storage location search unit 300 may extract the storage location of the user information based on the virtual authentication code, and extract the UID assigned to the storage location.

4, the storage location search algorithm is a k-shaped (k is MN) that moves along the track where MN codes corresponding to the first code are listed, and the vertices of the k-shaped code are on the first code track. When moving while corresponding to the arrangement point, each vertex of the k-shaped is matched with the storage location of the actual card number (user information), and the point where the first code track (i.e., the first track) and the k-shaped corresponds is the second It may be a starting point of searching for a storage location corresponding to code 1. In this case, rolling movement of the k-shaped can be applied so that the vertices of the k-shaped are in contact with the point corresponding to the extracted first code. Through this, the server 30 indicates the angle corresponding to the second code at the position on the first track where the k-gon is in contact (for example, a specific angle obtained by dividing 180 degrees into MN pieces to face the vertex of the k-gon). Accordingly, it is possible to search for the vertex of the k-shape, which is a storage location where the actual card number (user information) corresponding to the virtual authentication code is stored.

Specifically, as shown in FIG. 4 , the server 30 moves the k-gonal to a point corresponding to the first code (ie, moving while each vertex of the k-shaped and each point on the track are in contact with each other in turn). Thereafter, the server 30 searches for a vertex corresponding to the storage location by indicating the angular direction corresponding to the second code. For example, since 2 counts have elapsed since the virtual authentication code generating means B is issued the real card number, the virtual authentication code generating means B generates a second code by applying the 2 counts as a function value and provides it as a virtual authentication code verification means do. The virtual authentication code verification means matches and stores the second code generated by the second function for each count at the angle from the point where the k-shaped and the track are in contact with each vertex (that is, the second code to which the n count is applied to k As the cloud moves by n counts of the square shape, it matches and stores the angle toward the nth vertex where the cloud is moved), so the virtual authentication code verification means applies the angle corresponding to the second code to the first code corresponding point, The vertices of the k-gon corresponding to the storage location are searched for.

5 is an exemplary diagram of a storage space search algorithm for searching a storage space of user information by moving on a track based on a detailed code according to an embodiment of the present invention.

In one embodiment of the present invention, the server 30 includes a search algorithm, and the search algorithm moves on the track based on a plurality of detailed codes constituting the virtual authentication code to a point matching the UID assigned to the user. Go to and explore the payment code storage space.

Referring to FIG. 5 , the virtual authentication code includes a first code and a second code as a plurality of detailed codes generated based on a time elapsed from the time when the virtual authentication code generating function is driven.

As a specific example of the first code and the second code, the code value (first code value) corresponding to the first code may be a value obtained by adding the OTP code value to the count corresponding to the current time based on the virtual authentication code generating function driving time. have. The first code value serves as a waypoint in the actual code search process. The code value (second code value) corresponding to the second code may be a value obtained by subtracting the storage location value of the actual code from the first code value. The second code value is the count from the waypoint (first code value) to the actual code storage location value.

That is, an embodiment of the first code and the second code generated by the virtual authentication code generation module 200 are as follows.

1st code = current time count + OTP code

2nd code = 1st code - actual code storage location value

OTP (One time password) code is a code generated by the OTP code generation function included in the virtual verification number generation function, and is a code that is generated differently every time. Accordingly, since the detailed code is generated differently depending on the creation time of the virtual code, it is possible to prevent duplicated generation, and there is an effect of enhancing security.

As another specific example of the first code and the second code, the code value (first code value) corresponding to the first code is a value obtained by adding the UID value to the OTP code value, and the code value corresponding to the second code (second code) value) may be an OTP code value. In this case, a user identification (UID) value is a code value that is given to a user at a specific time (eg, a server registration time of user information, etc.) and can identify each user.

That is, another embodiment of the first code and the second code generated by the virtual code generation module 200 are as follows.

1st code = OTP code + UID

2nd code = OTP code

As shown in FIG. 5 , the server 30 passes the count on the track matching the first code value as a stopover point, and moves along the track in the direction set by the count corresponding to the second code value to receive the qualification number. A point matching the UID assigned to the corresponding user is searched, and the user information storage space connected to the UID is searched.
