These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with an embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

FIG. 1 schematically illustrates a server for issuing a call according to an embodiment of the present invention. The server 100 may include a communication unit 110 and a processor 120. The use of the same reference numerals is for convenience of explanation only and is not intended to mean that these individual devices are the same. In another embodiment of the present invention, the server may be configured differently to perform the corresponding method, or may perform the corresponding method through the same server 100.

In particular, the server 100 typically includes a computing device (e.g., a computer processor, memory, storage, input and output devices, and other devices capable of including components of a conventional computing device; (E.g., an electronic information storage system such as a network attached storage (NAS) and a storage area network (SAN)) and computer software (i.e., instructions that cause a computing device to function in a particular manner) ≪ / RTI >

The communication unit 110 of such a computing device can send and receive requests and responses to and from other interworking computing devices. As an example, such requests and responses can be made by the same TCP session, For example, as a UDP datagram.

The processor 120 of the computing device may include a hardware configuration such as a micro processing unit (MPU) or a central processing unit (CPU), a cache memory, and a data bus. It may further include a software configuration of an operating system and an application that performs a specific purpose.

Referring to FIG. 2, a method of issuing a call according to an exemplary embodiment of the present invention will now be described with reference to FIG. 1.

When a currency issuer A including a central bank of a specific country or a currency management subject of a specific organization generates and transmits a currency issue transaction TrxA through a terminal to issue a currency at step S100, And acquires the call issue transaction TrxA through the communication unit 110. [

At this time, the currency issuing transaction TrxA is configured to receive the call issuer information of (i) the call recipient information, (ii) the issue amount of the currency, (iii) the public key of the call issuer, and (iv) (i) the recipient information of the call, (ii) the issue amount of the call, and (iii) the signature value of the call issuer who signed the public key of the call issuer. The recipient information of the call may be a public key of a specific user registered as a call user as information on the recipient of the issued call, and the public key of the call recipient and the public key of the call issuer may be registered in advance in the server 100 The registration information may be registered by the issuer or the user having the private key and the public key registered in the server 100 as their own public key, Are described in other operations. The call issuer A may previously have the public key of the call recipient B as information on the call recipient B,

For example, the currency issue transaction (TrxA) has a data format of 1. payment settlement method, 2. previous transaction ID, 3. recipient, 4. issuance amount, 5. issuer public key, 6. issuer signature value But is not limited thereto.

At this time, "1. Payment method "may include" immediate payment "and" delayed payment ", where the" immediate payment "is to process the currency transaction immediately and the" delayed payment " It may be to delay processing of the associated transaction. For example, "delayed payment" means that if you make a payment for more than your balance in order to resolve the liquidity problem if you do not have enough money to pay, you can offset the amount you receive afterwards . However, since the issuer of the currency is the agency issuing the new currency or the equivalent party, the issuance of the currency does not result in a "delayed payment settlement" and therefore the "immediate payment settlement" is set as the default or the " Data format may not be included. And, "2. The previous transaction ID " includes information on the balance of the issuer or the user, and includes a private block chain database in which transactions previously generated or traded in association with the currency are registered, or a private transaction ID Or a public transaction ID, the issuance of the currency may generate a new currency and thus may not have a previous transaction ID. Also, " 3. Recipient " may be the public key (PubB) of the recipient of the call to receive the issued call, and " 4. Issuing amount "may be the amount of money to be issued, and" 5. Issuer public key " may be a public key PubA registered by the issuer, and " 6. Issuer signature value " may be a signature value (SigPrivA (1, 2, 3, 4, 5)) of 1, 2, 3, 4, 5 signed by the issuer with a private key.

Then, the processor 120 of the server 100 determines whether or not the caller information acquired through the communication unit 110, (ii) the issue amount of the call, (iii) the public key of the call issuer, and (iv) And the validity of the call issuer (S110). At this time, the processor 120 of the server 100 confirms whether the data format of the currency issue transaction TrxA is valid, whether the call receiver is valid, whether the public key of the call issuer is valid, and whether the signature value of the call issuer is valid And confirms the validity of the currency issue transaction (TrxA). As an example, it is confirmed whether the public key of the call receiver and the call issuer acquired by using the public key of the call issuer with respect to the signature value of the call issuer A matches the value included in the call issuance transaction (TrxA) And the validity of the public key of the call issuer. In addition, the signature value of the call issuer can be verified by using the public key of the call issuer, so that the validity of the signature value of the call issuer can be verified, and it is possible to confirm whether or not the call issuer is a valid call issuer through the public key of the call issuer.

If it is determined that the confirmation result (S110) is valid (S210), the server 100 determines whether or not the validity of the call issuer, the call issuer information, the issuance amount of the call, (iii) (S211) to register or register in the private block chain database (S211) a currency issuing transaction (TrxA) including the value of the currency issuing transaction (TrxA) (S212, S213) to provide or provide the issuing private transaction ID (PrivTxid) to at least some of the call issuer (A) and the call receiver (B). However, if the confirmation result (S110) is not valid (S220), the server 100 may support to provide or provide a response indicating failure including the error message to the call issuer A (S221). However, it is essential that the present invention is registered in the public block chain database 120, which will be described later, and it may not be essential to register in the private block chain database.

If the triggering condition for registering a predetermined hash value in the public block chain database is satisfied (S230), the server 100 determines (i) the call recipient information, ( a hash value (hash (TrxA)) generated by applying a hash function to a call issuing transaction (TrxA) including the issuance amount of the call, ii) the amount of issued currency, (iii) the public key of the call issuer, and A value obtained by processing a representative hash value or a representative hash value by computing at least one neighbor hash value matching the specific hash value is generated as a much route (S231), and the representative hash value or the representative hash value, which is the generated muffle root, is processed (S232), and stores the representative hash value or the representative hash value registered in the public block chain database 120 in the public block chain database 120 To obtain or obtain a call issuing public transaction ID (Txid) indicating location information on the public block chain database (S233). At this time, the server 100 may obtain the OP message corresponding to the call issuing public transaction ID (Txid) from the public block chain database 200. [

The hash function may be an MD4 function, an MD5 function, a SHA-0 function, a SHA-1 function, a SHA-224 function, A SHA-256 function, an SHA-384 function, a SHA-512 function, and a HAS-160 function. For example, Triple SHA256 would be possible.

At this time, the server 100 may store and manage a specific hash value and at least one neighbor hash value in a predetermined data structure. Here, the data structure may be various, for example, a merkle tree structure. In this case, the calculation of a particular hash value and at least one neighbor hash value can be done through a merkle tree.

That is, the server 100 may support to generate or generate a merkle tree that a particular hash value is assigned to a particular leaf node, and if the predetermined condition is satisfied, at least one other leaf It is possible to register or register a value obtained by processing a representative hash value or a representative hash value, which is a merge root generated by computing a hash value assigned to a node, in the public block chain database 120. [

More specifically, (x1) server 100 supports to calculate or calculate a hash value assigned to (i) a particular hash value and (ii) a sibling node of a node to which a particular hash value is assigned, You can support assigning or assigning a hash value for a value to a node's parent node. (x2) If the parent node is the root node of the merge tree, the hash value assigned to the parent node is the representative hash value. (x3). On the other hand, if the parent node is not the root node of the merge tree, the server 100 repeats (x1) to (x3) with the hash value assigned to the parent node as a specific hash value.

Then, the server 100 finally registers the hash value assigned to the root node of the merge tree as a representative hash value in the public block chain database 120 or supports registration. At this time, a value obtained by processing the representative hash value may be registered. For example, a result obtained by performing a hex operation on a representative hash value may be registered.

Meanwhile, when the server 100 stores a specific hash value and at least one neighbor hash value in a predetermined first data structure and then stores and manages a second data structure of the same type as the first data structure, The data structure and the second data structure may be concatenated in a chain form.

In particular, if the first data structure and the second data structure are merc trees as in the above example, the root value of the first data structure or the hash value of the root value may be assigned to the first leaf node of the second data structure .

Further, when the second data structure is generated, verification of the first data structure is performed, so that data integrity can be further ensured. Verification of the second data structure will be described later.

In addition, in the case of the first one of the at least one merch tree connected in a chain form, the first leaf node of the first merch tree may be assigned a hash value or a processed value of predetermined message data composed of text, numbers, or symbols have. For example, a hash value of an input message initially assigned by the server 100 when generating a merge tree can be assigned.

FIG. 3 and FIG. 4 are views showing examples of a merge tree generated according to an embodiment of the present invention.

FIG. 3 shows a merge tree having four leaf nodes. Since the illustrated merge tree is the first merge tree (tree_id = 0), it can be seen that a hash value (sha256 (coinplug_unique_message)) of a predetermined message data is assigned to the first leaf node h0. When there is a registration request for write data (i.e., a write request related to messenger service transmission / reception data), the server 100 generates a next leaf node of the last leaf node of the currently configured MUCLE tree, Supports assignment or assignment of processed values. For example, if a new leaf node needs to be created in a state where the value assignment from the merge tree to the h1 node as the second leaf node is completed, a h2 node, which is a next leaf node, is generated to process a specific hash value or a specific hash value One value (sha256 (input2)) can be assigned. The server 100 may also support computing or computing (i) a particular hash value assigned to the h2 node and (ii) a hash value assigned to the h3 node, which is a sibling node of the h2 node. The hash value for the computed value is assigned to the h2 node and the parent node (h23 node) of the h3 node. Since the parent node (h23 node) is not the root node of the merge tree, the server 100 can repeat the above process with the hash value assigned to the h23 node as a specific hash value. That is, the hash value assigned to the h23 node is set as a specific hash value, and the hash value assigned to the h23 node and the hash value assigned to the h01 node are calculated and assigned to the h23 node and the parent node (h0123 node) of the h01 node have. At this time, since the h0123 node is the root node of the merge tree, the server 100 registers or registers the value (hex (h {node_index})) obtained by processing the hash value assigned to the node h0123 in the public block chain database 120 .

(Ii) a condition that a predetermined time elapses; (iii) a condition in which a block is generated in a private block chain; (iv) a condition in which a transaction is generated by a predetermined number of And < RTI ID = 0.0 > a < / RTI > service characteristic. At this time, the transaction related to the call may include issuer registration, payment settlement of currency, user registration, etc., in addition to issuance of the currency.

Meanwhile, for example, when a plurality of call related transactions are obtained for the number of leaf nodes of the merge tree, a merge tree may be created, and the root value of the merge tree may be registered or registered in the public block chain database 120.

In addition, the server 100 can generate the root value of the aforementioned mu tree at predetermined time intervals (condition (ii) above). In this case, the server 100 may generate a merge tree using the input values up to that time and register or register the root value of the merge tree in the public block chain database 120 when a predetermined time has elapsed.

In this case, although a predetermined time has elapsed, a value may not be assigned to a sibling node of a node to which a particular hash value of the merge tree is assigned. If the hash value is not allocated to the sibling node of the node to which the specific hash value is assigned even though the predetermined condition is satisfied, the server 100 supports to assign or assign a predetermined hash value to the sibling node, The root value of the merge tree can be calculated. For example, the server 100 may support to replicate and allocate or assign a particular hash value to a sibling node.

The service characteristic includes at least one of cost information provided by the issuer of the call issuance request, time zone information in which the call issuance transaction registration is performed, region information in which the call issuance transaction registration service is performed, It can be a part. However, the present invention is not limited to the one described here, but includes various condition information in which a generally accepted differential service can be provided.

On the other hand, when a new merge tree generation is started and a predetermined condition is satisfied in the absence of a call issuing transaction, the server 120 generates a merge tree in which predetermined message data is allocated to the first leaf node and the second leaf node And supports to register or register the route value of the merge tree or the processed value in the public block chain database 120. [ In this case, a merge tree with two leaf nodes may be created.

Meanwhile, as described above, when the server 100 stores a specific hash value and at least one neighbor hash value in a predetermined first data structure and then stores and manages a second data structure of the same type as the first data structure , The first data structure and the second data structure may be connected in a chain form. In particular, if the first data structure and the second data structure are merc trees, the root value of the first data structure or the hash value of the root value may be assigned to the first leaf node of the second data structure.

4 is a diagram illustrating a merge tree generated as a second data structure according to an embodiment of the present invention.

Referring to FIG. 4, it can be seen that the root value (hex (h0123)) of the merge tree (tree_id = 0) of FIG. 3 is assigned to the first leaf node (h4 node) of the new merge tree (sha256 (input4)). The present invention has an advantage of improving data integrity by enabling easy tracking even when data is modulated in the middle by connecting a plurality of data structures generated at the time of occurrence of a transaction.

Next, a process of registering the call issuer A will be described with reference to FIG.

When the issuer registration request by the public key PubA of the call issuer A is obtained S300, the server 100 confirms the validity of the call issuer A, and when the issuer A is valid S310) and may support delivery or delivery of the random nonce (RN) to the call issuer A (S311). If the call issuer A is not valid (S320), for example, if the person is a person who has stolen the name of another person, the server 100 provides the call issuer A with a response indicating the issuer identification failure (S321). However, the method for determining whether the issuer A is valid is not limited to this, and the validity of the issuer A may be determined using a time stamp, for example. For reference, an example will be described below in which validity is judged by using random nonce.

When the call issuer A transmits the public key PubA to the server 100 in order to register the issuer for issuing the call with the private key PrivA and the public key PubA created in the terminal, (100) confirms that the call issuer (A) of the obtained public key is valid. At this time, the validity of the call issuer A may be determined by using a public key infrastructure (PKI) certificate or by using the identification information of the call issuer A, but the present invention is not limited thereto. For example, it is possible to identify a specific issuer through a public key-based certificate, an OPSign certificate, or the like, or to provide identification information that can prove the identity of an individual, a bank or an organization such as a resident registration number, a passport, To identify the call issuer.

Thereafter, when the random non-signature value SigPrivA (RN) obtained by signing the random number RN with the private key of the call issuer A is obtained (S312), the server 100 determines whether the random non- And verifies using the public key of the call issuer A. [ That is, the server 100 confirms the random nonce (RN) from the random nonce signature value using the public key of the call issuer, and determines whether the confirmed random nonce (RN) matches the random nonce (RN) If it matches, it verifies that it is a valid signature.

If the signature value obtained from the call issuer A is valid (S330), the server 100 transmits an issuer registration transaction RN, SigPrivA (RN (RN), RNN ), PubA) to the private block chain database (S331), and includes an issuer-registered private transaction ID (PrivTxid) indicating the location information on the private block chain database of the issuer registration transaction registered in the private block chain database (S332) to provide or provide a response to the call issuer A indicating that the registration is successful.

However, the server 100 may assist the call issuer A to provide or provide a response including a message indicating a failure to verify the signature value when the signature value obtained from the call issuer A is not valid (S340) (S341).

If the triggering condition for registering a predetermined hash value in the public block chain database is satisfied (S350), the server 100 determines whether the signature value of the call issuer is valid or not based on the randomness, (Hash (RN, SigPrivA (RN), PubA) generated by applying a hash function to the issuer registration transaction including the value of the public key of the issuer and the public key of the issuer, and at least one neighboring hash value (S351). A value obtained by processing the representative hash value or the representative hash value, which is the generated merge root, is registered in the public block chain database (S352). A public block chain having a value obtained by processing a representative hash value or a representative hash value, which is a merge root registered in the public block chain database 120 (S352) to obtain or obtain an issuer-registered public transaction ID (Txid) indicating location information on the database 120. [ At this time, the value obtained by processing the representative hash value or the representative hash value, which is the merge root, can be generated by the merge tree as shown in FIG. The server 100 may acquire the OP message corresponding to the publisher registered public transaction ID (Txid) from the public block chain database 200. [

Next, a method of paying a call according to an embodiment of the present invention will be described with reference to FIG. In the following description, a portion similar to the method of issuing a call according to the embodiment of the present invention shown in Fig. 2 can be understood from the description of Fig. 2, and a detailed description thereof will be omitted.

When a second call transaction TrxC for payment of a call from a specific user C is transmitted from a terminal of a specific user C to settle the payment of the call, the server 100 transmits the second call transaction TrxC to the communication unit 110 (S400).

At this time, the second call use transaction TrxC includes at least one unused at least one first call use transaction ID, (ii) call recipient information, (iii) payment amount, (iv) (Ii) a call recipient information; (iii) a payment payment amount; (iv) a specific user's private key; (i) And may include the signature value of a particular user who signed the public key. At least one of the at least one unused at least one transaction-use transaction ID previously used is a currency-related transaction in which a usage amount is left for payment payment received from a currency issuer or other users by a specific user. The sum of the unused amounts of all the first call-enabled transactions may be the current balance of a particular user. The call recipient information may be the public key of the call recipient who receives the payment to be paid among the users who are registered as the call user as the information on the recipient of the paid-out call. The public key of the call recipient and the specific user C May be registered in the server 100 in advance or may be registered in the server 100 at the time when necessary, and the registration information may be issued by an issuer or a user having a private key and a public key, The key is registered in the server 100, and a description thereof will be given in another operation. Also, the specific user C may have the public key of the call recipient in advance as information on the call recipient.

For example, the second call transaction (TrxC) includes: 1. payment settlement method; 2. transaction ID used for the first call; 3. recipient; 4. usage amount; 5. balance; 6. balance owner information; A public key of a particular user, and a signature value of a particular user.

At this time, "1. Payment method "may include" immediate payment "and" delayed payment ", where the" immediate payment "is to process the currency transaction immediately and the" delayed payment " It may be to delay processing of the associated transaction. For example, "delayed payment" means that if you make a payment for more than your balance in order to resolve the liquidity problem if you do not have enough money to pay, you can offset the amount you receive afterwards . And, "2. Quot; first call use transaction ID " includes information on the balance of the specific user (C), and indicates a private block chain database or a public block chain database upper position information registered in the previously used currency use transaction A private transaction ID, or a public transaction ID, which is related to the information of the currency use transaction including the currency use transaction and the unused amount, which is paid by the issuer or other users of the currency, The balance of all the first call usage transactions may be the balance currently owned by the particular user C. [ Also, " 3. Recipient " may be the public key (PubB) of the recipient of the call to receive the payment, and " 4. The amount used may be the amount you wish to pay for, and "5. Balance "is the amount remaining after the payment in the balance of the specific user (C), and may have no balance or negative value due to the settlement of payment. The balance owner information is "5. In the present embodiment, there may be no information when there is no balance with the public key of the specific user C, and " 7. Public key of the specific user " may be the public key of the specific user C who is going to make a payment now, and " 8. SigPrivC (1, 2, 3, 4, 5, 6, 7) signature values of 1, 2, 3, 4, 5, 6, 7 signed by a particular user C with a private key, ).

Then, the server 100 refers to the balance of the specific user C to check the payment settlement method of the second call use transaction. At this time, if the balance owned by the specific user (C) is equal to or greater than the payment settlement amount, it is confirmed as "immediate payment settlement". If the balance owned by the specific user (C) is less than the payment settlement amount, . In addition, it can be confirmed as "immediate settlement payment" and "delayed payment settlement" according to the payment settlement method included in the second call use transaction. In particular, the payment settlement method included in the second currency use transaction is referred to as "immediate payment settlement" If the balance entered by a particular user (C) is less than the payment settlement, it can be determined as "delayed payment settlement".

At this time, if the second call use transaction TrxC is confirmed as " immediate payment " (S410), the server 100 determines whether the signature value of the specific user C in the second call use transaction TrxC is valid If it is valid (S430), the second call use transaction TrxC is registered in the private block chain database (S431) and position information on the private block chain database of the second call use transaction TrxC registered in the private block chain database (PrivTxid) indicating that the second call is to be used to provide or provide the second currency-use private transaction ID (PrivTxid) to at least some of the specific user (C) and the call recipient (S432). However, the server 100 may support to provide or provide a response indicating failure including the error message to the specific user C (S441) if the verification result is not a valid signature value (S440).

If the triggering condition is satisfied under a predetermined condition, for example, S450, the server 100 generates a specific hash value (hash) generated by applying a hash function to the second call use transaction TrxC (TrxC)) and a neighboring hash value matched with a specific hash value to generate a value obtained by machining a representative hash value or a representative hash value (S451), and generates a representative hash value or a representative hash value (Step S452). In step S452, the public block chain database 200 stores the processed value in the public block chain database 200 (step S452). The public block chain database 200 stores the representative hash value To acquire or obtain a second call-enabled public transaction ID (Txid) indicating location information on the chain database (S453). At this time, the value obtained by processing the representative hash value or the representative hash value, which is the merge root, can be generated by the merge tree as shown in FIG. The server 100 may obtain the OP message corresponding to the second call use public transaction ID (Txid) from the public block chain database 200.

On the other hand, when the second call use transaction TrxC is confirmed as " delayed payment " (S420), the server 100 determines whether the signature value of the specific user C in the second call use transaction TrxC is valid (S470) and stores the second call transaction (TrxC) in a recording device such as a netting database, a storage unit, a memory, or the like (S471). However, if the verification result is not a valid signature value (S480), the server 100 may support to provide or provide a response indicating failure including the error message to the specific user (S481).

 Then, in a state where the second call use transaction (TrxC) is stored in the storage device, at least one or more third call use transactions (hereinafter referred to as " TrxD is obtained (S472), the server 100 confirms whether the acquired third call-enabled transaction TrxD and the second call-enabled transaction TrxC satisfy the upper-limit condition. At this time, the third call use transaction (TrxD) may be a call use transaction stored in the storage device as a payee of the specific user (C) as a "delayed payment". In this case, The server 100 can perform the offset processing for the second call use transaction TrxC in response to the offset processing of the stored third call use transaction TrxD. (TrxD) is obtained, it is determined whether or not the balance of the specific user (C) has a value of "0" or more by the upper-order processing.

On the other hand, if the offset condition is not satisfied by the acquired third call transaction TrxD (S500), the server 100 stores the acquired third call transaction TrxD on the recording medium, And waits for the used transaction to be acquired (S501).

In this state, if the offsetting condition is satisfied by at least one third call-enabled transaction TrxD (S490), that is, the amount to be received by the plurality of third call-enabled transactions TrxD is the second call- TrxC) or the sum of the amount of money to be received by the third currency use transaction (TrxD) and the balance of the second specific user (C) exceeds the amount to be paid by the second currency use transaction TrxC The server 100 processes the second call use transaction TrxC and at least one or more third call use transactions TrxD. At this time, a plurality of third currency transactions TrxD are generated by a plurality of currency transactions generated by a specific other user, a plurality of currency transactions generated by a plurality of other users, or a plurality of other users, Or may be a currency transaction created by a number of other users.

In addition, when a specific user C and a plurality of other users are connected to a payee and a recipient of a currency use transaction of "late payment settlement" respectively to form a circulation loop, And "delay payment settlement" among a plurality of other users, and can process all the connected currency transactions. Of course, if any currency-using transaction identified as "deferred payment" does not satisfy the offsetting condition due to the difference in payment settlement amount with another currency-using transaction, the offsetting condition of any currency-using transaction, When an arbitrary currency-using transaction satisfies the upper-level processing condition by the currency-using transaction, the server 100 can offset all the call-using transactions that are "delayed payment"

As an example, the user A creates a call-using transaction A as a "delayed payment" to the user B, the user B creates a call-using transaction B as a "delayed payment" to the user C, Delayed payment ", and the user D generates a currency-use transaction D as the" delayed payment "to the user A, so that the user A, the user B, the user C, In the case where the circulating loop as the payee is formed, the server 100 transmits the call use transaction A, the call use transaction B, the call use transaction C, and the call use transaction D generated by the user A, the user B, the user C and the user D It is possible to perform an offset process. Of course, the condition that the settlement payment amounts in the respective currency use transactions of "delayed payment settlement" must be met, and if the settlement payment amounts do not match, each currency use transaction of "delayed payment settlement" The uplink processing can be performed when each of the " late payment settlement ", that is, the currency use transaction satisfying the upper limit processing condition and satisfying the upper limit processing condition by another currency use transaction satisfies the upper limit processing condition.

The server 100 supports registering or registering the second call use transaction TrxC and the at least one third call use transaction TrxD in the private block chain database at step S491, (PrivTxid) indicating the location information on the private block chain database of at least one or more third call use transaction (TrxD) registered in the second call use transaction (TrxC) and the third call use private transaction (S492, S493) to provide or provide the ID (PrivTxid) to at least some of the specific user (C), the call recipient, and at least one or more other users (D). At this time, information stored in the recording medium, that is, the second call use transaction TrxC and the acquired at least one third call use transaction TrxD can be deleted.

If the triggering condition is satisfied under a predetermined condition, for example, at step S510, the server 100 determines whether or not the second call use transaction (TrxC) A representative hash value generated by calculating a specific hash value generated by applying a hash function to the second call use transaction and at least one neighbor hash value matched with the specified hash value, or a value obtained by processing the representative hash value, (S511), and supports registration or registration in the public block chain database (S512). Also, the server 100 may generate a hash value by applying a hash function to each of the at least one third call-enabled transaction that has undergone the offset process, and at least one neighbor hash value matching the specific hash value, Value or the value obtained by processing the representative hash value may be generated as a muckrout (S511), and registered or registered in the public block chain database (S512). That is, the server 100 can support registration or registration of information on all the currency-used transactions that have been processed in the public block chain database 200.

Then, the server 100 obtains the information indicating the location information on the public block chain database of the muckrout corresponding to each of the muckle route corresponding to the second call using transaction registered in the public block chain database and each of the at least one third call using transaction (Step S513) to acquire or obtain at least one call-using public transaction ID (Txid) and at least one or more third call-using public transaction ID (Txid). At this time, the value obtained by processing the representative hash value or the representative hash value, which is the merge root, can be generated by the merge tree as shown in FIG. The server 100 may obtain the OP message corresponding to the second call use public transaction ID (Txid) and the third call use public transaction ID (Txid) from the public block chain database 200, respectively.

A process of registering a specific user who is a call user will be described below. The registration of the specific user also performs the same method as the registration of the call issuer in FIG. 5, and a similar portion is omitted because it can be understood by the description in FIG.

When the user registration request by the public key of the specific user C is obtained, the server 100 confirms the validity of the specific user C, and when the specific user C is valid, ) To the customer. When the specific user C is not valid, the server 100 can support the specific user C to provide or provide a response indicating the user confirmation failure.

On the other hand, in the case of a valid user, when the random non-signature value obtained by signing the random non-existence with the private key of the specific user is obtained, the server 100 verifies whether the random non-signature value is normally signed using the public key of the specific user .

When the signature value obtained from the specific user C is valid, the server 100 registers the user-registered transaction including the random non-existence, the random non-signature value, and the public key of the specific user in the private block chain database, , And can support or provide a specific user C with a user-registered private transaction ID (PrivTxid) indicating the location information on the private block chain database of the user-registered transaction registered in the private block-chain database.

However, the server 100 may assist the specific user 111 in providing or providing a response indicating failure to verify the signature value when the signature value obtained from the specific user C is invalid.

In addition, when the signature value of the specific user C is valid, the server 100 may perform a user registration transaction including a random non-existence, a random non-signature value, and a public key of a specific user when a predetermined condition, A representative hash value that is generated by computing a specific hash value generated by applying a hash function and at least one neighbor hash value matched with the specified hash value, or a value obtained by processing the representative hash value, 200 or a publicly registered public transaction chain ID (200) indicating the positional information on the public block chain database of the value obtained by processing the representative hash value or the representative hash value registered in the public block chain database 200 ≪ / RTI > Txid). At this time, the value obtained by processing the representative hash value or the representative hash value, which is the merge root, can be generated by the merge tree as shown in FIG.

Meanwhile, the call recipient B, the call user C, and the call user D described above may be a commercial bank or a general person.
