First, a process of issuing and distributing stocks using virtual money will be described with reference to FIGS. 1 and 2. FIG.

Referring to FIG. 1, a server 100 according to an embodiment of the present invention includes a communication unit 110 and a processor 120.

The communication unit 110 transmits and receives data to and from a user 400 or a user terminal, a specific company 300 or a company terminal, and a database 200. The communication unit 110 can acquire the stock issue and distribution request (S205). When a stock issuance and distribution request is obtained as shown in FIG. 2, a share list file and a public key (PubA) of the specific company 300 can be obtained. The communication unit 110 can respond to the request (S215), and a response corresponding to the request can be made during one TCP session. However, since the server 100 does not necessarily have a shareholder file, the above-described process can be omitted.

The processor 120 may support to generate or generate a message digest (MD = Hash (File)) of the shareholder file using the hash function if there is a stock issue and distribution request (S210). The type of the hash function is not limited. For example, the hash function may be triple sha256. In the present specification, a hash function generally refers to a function for transforming an original file, but in an extreme case, it may include a function for simply storing a file without any processing. In this case, the message digest generated by applying the hash function may be the same as the specific file.

In step S215, the generated message digest may be transmitted to the specific company 300 in response to the stock issue and distribution request. If the specific company 300 makes a request through a terminal (not shown), the generated message digest may be transmitted to the terminal.

Next, the communication unit 110 may acquire a message digest (EncPrivA (MD)) signed by the private key (PrivA) of the specific company 300 from the specific company 300 (S220). In this case, since the TCP session may be disconnected after the response in step S215, the message digest from the specific company 300 and the public key (PubA) of the specific company may also be received.

The processor 120 obtains a message digest signed with the private key of the specific company 300 and verifies the message digest signed by the private key of the specific company 300 with the public key of the specific company 300 (S235-2), it can support or execute a stock issuing transaction for transferring virtual money representing a predetermined number of shares at the address of the specific company 300 (S235) . At this time, unlike the case described above, the server 100 may not receive the shareholder list file. In this case, the step S205 to S225 may not be performed and the step S235 may be performed immediately.

The stock issuance transaction is defined as a transaction in which the server 100 transmits the virtual money corresponding to the number of shares issued by the specific company 300 to the address of the specific company 300 on the block chain. At this time, the transferred virtual money corresponds to the issued stock. In the present invention, a specific virtual currency is used as a specific stock in correspondence with a specific stock. Thus, the existing virtual currency is used with a specific meaning, so it can be called colored coin.

 The stock issuance transaction includes a predetermined amount of virtual money as an input, and a hash value (Hash [SigPrivC (statement (Hash)] for information obtained by signing information including a predetermined record related to the stock with the private key of the server 100 )] And an operation of transmitting the virtual money of the predetermined amount to the address of the specific company 300 as an output. The predetermined record associated with the stock may be a variety of records. For example, it may be a record indicating that the server 100 has issued a certain number of shares to a specific company 300. In addition, the stock issuing transaction may further include a virtual currency for the transaction fee as an input.

When the stock issuance transaction is recorded on the database 200, the communication unit 110 obtains a first transaction ID indicating the position information recorded on the database 200 (S240). The first transaction ID is also transmitted to the specific company 300 (S245). Here, the database 200 may be a block chain of virtual money. For example, it may be a bit coin block chain.

Next, the processor 120 generates a multisig address indicating an address for distributing the issued stock using the public key of the shareholder, the public key of the specific company 300, and the public key of the server 100 (S255). The multisig address may be generated by the server 100 or another device (e.g., a terminal of the company 300), but a transaction that distributes and transmits the stock may be ultimately performed by the company 300. When the server 100 generates a multisig address, the public key PubD of the user 400 is provided as shown in FIG. 2 (S250).

Here, the multisig address may be a pay-to-script hash (P2SH) address used in the virtual money system. For example, the multisig address may be a 3-based address used in the bit coin. The processor 120 uses the public key of the shareholder 400, the public key of the specific company 300 and the public key of the server 100 to generate a redeem script (RDSD = Func (PubD, PubA, PubC)). A redeem script is a lock script that is replaced by a hash in a P2SH transaction. The processor 120 may support generating or generating the multisig address by encoding the generated redeem script. The encoding may be Base58 encoded (MSAD = Base58Check (RDSD)).

The user 400 and the specific company 300 receive the generated RDSD and MSAD (S260, S265). Processor 120 may support performing a stock distribution transaction to transfer at least a portion of the virtual currency to the generated multisig address (S275). The stock distribution transaction may be made at the request of the specific company 300 (S270).

The stock distribution transaction may include as input an amount of virtual money sent as an input to the address of the specific company 300 and an output to transmit at least a portion of the predetermined amount of virtual money to the multisig address have. In addition, the stock distribution transaction may further include an operation of returning, as an output, an address of the specific company 300 other than the at least a portion of the predetermined amount of virtual money. However, it is also possible to transmit them in parallel at several addresses. The stock distribution transaction may further include an operation of further including a virtual currency for a transaction fee as an input and returning the remainder of the fee to a predetermined address as an output.

When the stock distribution transaction is recorded on the database 200, the communication unit 110 obtains a second transaction ID indicating location information recorded on the database 200 (S280).

Meanwhile, when the stock distribution is completed, the processor 120 may generate a shareholder file (S290, meaning that the server stores the file) and store or store the shareholder file (FileC) (S295). The share list file can be AES encrypted and stored. The shareholder file can store shareholders' public keys, RDS, and MSA.

Next, the process of transferring ownership of shares issued using virtual money will be described with reference to FIGS. 1 and 3. FIG.

The communication unit 110 acquires the stock ownership transfer transaction information reqTransDE indicating the previous transaction details of the stock ownership of the specific company 300 between the first user 400-1 and the second user 400-2, (TransDE = Hash (reqTransDE)) for the stock ownership transfer transaction information (S305, S310).

Upon acquiring the stock ownership transfer transaction information, the processor 120 generates or generates a hash value for the stock ownership transfer transaction information (S310), and determines whether the information related to the stock ownership transfer transaction information is true (S325). If the check result is true (S325-2), it is supported to generate or generate an unsigned transaction as follows.

That is, if the result of the check is true, the processor 120 transmits at least a part of virtual money of a predetermined amount corresponding to a predetermined number of shares of the first user 400-1 to the second user 400- 2) unsigned transaction (UST) to be transmitted to the multisig address (S335).

The unsigned transaction includes (UTXO) a virtual money of a predetermined amount corresponding to a predetermined number of stocks of the first user 400-1 as input and outputs at least a part of the virtual money of the predetermined amount as the 2 to the multisig address of the user 400-2 and the remaining part of the virtual money of the predetermined amount excluding the at least a part of the virtual money to the address of the first user 400-1 as an output . The generated unsigned transaction is transmitted to the first user 400-1 (S340). In addition, it may further include a virtual money for a transaction fee as an input of the unsigned transaction, and returning the remainder of the fee to a predetermined address as an output.

The process of confirming whether the information related to the stock ownership transfer transaction information is genuine can be performed as follows.

The processor 120 may assist in generating or generating a hash value (TransDE = Hash (reqTransDE)) of the stock ownership transfer transaction information using the hash function when the stock ownership transfer transaction information (reqTransDE) is acquired. The type of the hash function is not limited. For example, the hash function may be triple sha256. In the present specification, the hash function generally refers to a function for transforming an original file, but in an extreme case, it may include a function for simply storing stock ownership transfer transaction information without any processing.

In step S320, the generated TransDE can be transmitted to the first user 400-1. If the first user 400-1 requests the stock ownership transfer through the terminal (not shown), the generated TransDE can be transmitted to the terminal.

Next, the communication unit 110 may acquire a TransDE (SigPrivD (TransDE)) signed by the private key (PrivD) of the first user 400-1 from the first user 400-1 (S320) . In this case, the TransDE and the public key PubD of the first user 400-1 may be received from the first user 400-1 since the TCP session may be disconnected after the response of step S315.

In addition, the processor 120 may determine whether the result of checking the TransDE signed with the private key of the first user (400-1) using the public key of the first user (400-1) is true S325).

Meanwhile, when a partly signed transaction (PST) signed by the private key of the first user (400-1) is obtained (S345, S350), the processor 120 determines whether the partly signed transaction (i) signing with the private key of the server 100 or (2-of-3 address) (ii) signing with the private key of the specific company 300 (2-of-3 address) (3-of-3 address) Fully Signed Transaction (FST) by signing with the private key of the specific company 100 and the private key of the specific company 300 (S355). (iii) is not limited to the signature sequence.

The communication unit 120 supports transmission or transmission of the generated fully signed transaction (FST) to the database 200 (S375), and the fully signed transaction transmits position information recorded on the database 200 The transaction ID may be obtained (S380)

On the other hand, when the stock ownership transfer is performed, the processor 120 may support updating or storing or storing the shareholder file. Specifically, the processor 120 supports decrypting or decrypting the existing share list file stored at step S360, updating the decrypted share list file at step S365, and updating the updated share list file FileC ' May be encrypted and stored or stored (S370). The updated share list file can be AES encrypted and stored.

When the stock ownership transfer is completed, the communication unit 110 transmits a transaction success message to the first user 400-1, the second user 400-2, and the specific company 300 (S385).

Meanwhile, the processor 120 functions to control the flow of data between the communication unit 110 and other components. That is, the processor 120 controls the flow of data between each component of the server 100 to control the communication unit 110 and other components to perform their own functions.

The processor 120 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.

In addition, the embodiments of the present invention described above can be implemented in the form of program instructions that can be executed through various computer components and recorded in a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, and the like, alone or in combination. The program instructions recorded on the computer-readable recording medium may be those specially designed and constructed for the present invention or may be those known and used by those skilled in the computer software arts. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks and magnetic tape, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like.
