However, in the above-described embodiment, when an OP message is generated for each file and is recorded in a block chain, a bottleneck phenomenon of service provision may occur when transaction requests are increased. There are disadvantages that can be costly.
Hereinafter, the above-mentioned disadvantages are compensated for, while making it possible to support the registration of the shareholder list or the transfer of the ownership of the stock in real time, which can not be stooped / altered and real time, Describe unlisted stock trading support systems. This system uses a separate data structure managed by the
The
That is, the
The computation of a particular hash value and at least one neighbor hash value may be performed by various functions. A particular hash value is denoted as input, and at least one neighboring hash value is denoted by x1, x2, ... , xn, the representative hash value t can be expressed by the following equation.
≪ Equation &
t = hash (function (input, x1, x2, ..., xn))
At this time, the

Meanwhile, the
In particular, as in the above example, 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 the first leaf node of the second data structure Lt; / RTI >
In addition, when the second data structure is created, verification of the first data structure is performed, so that data integrity can be further guaranteed. Verification of the second data structure will be described later.
In addition, in the case of the first merge tree among the at least one merge tree connected in a chain form, the first leaf node of the first merge tree is assigned a hash value of a predetermined message data composed of text, numbers, or symbols or a processed value thereof . For example, a hash value of an input message initially assigned by the
FIGS. 3 and 4 are views showing examples of a merge tree generated according to an embodiment of the present invention.
In FIG. 3, the number of leaf nodes is 4 (22) An individual mu tree is shown. Since the illustrated merge tree is the first merge tree (tree_id = 0), it can be seen that the hash value (triplesha256digest (coinplug_unique_message)) of the predetermined message data "Coinplug 2016-01-01" is assigned to the first leaf node h1. If there is a registration request for the shareholder list file, the
On the other hand, the predetermined conditions are (i) conditions in which a predetermined number of share list files are acquired or a predetermined number of message digests are generated, (ii) conditions in which a predetermined time elapses, (iii) A condition in which a block is generated in the service characteristic, and (iv) a condition for a service characteristic.
For example, if a plurality of shareholder registration requests are made and a message digest is obtained for the number of leaf nodes of the muckle tree, the result of encoding each private key of each user and the private key of the
In addition, the
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 allocated, the
The service characteristic includes at least one of cost information paid by a user who made a request for registration of a shareholder list, time zone information at which the shareholder list registration is performed, region information at which the shareholder list registration service is performed, . 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 the predetermined condition is satisfied without acquiring a shareholder list file or a message digest, the
Meanwhile, as described above, the
4 is a diagram illustrating a merge tree generated as the 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 (triplesha256digest (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 performing verification on the registered share list file using the above-described data structure will be described.
The
Here, the second representative hash value may be a second specific hash value, and the second specific hash value may be (i) related to the input data included in the verification request, (Ii) a hash value of a file in which the shareholder list file A is signed by the private key of the
At this time, the input data included in the verification request includes any one of (i) the shareholder list file, (ii) a message digest for the shareholder list file, or (iii) an ID issued at the time of registering the shareholder list file can do.
In the case where the share list file is included in the input data, the message digest for the shareholder list file is generated in the above-described manner, and the second specific hash value can be calculated based on the message digest. The second representative hash value may be generated by calculating at least one neighboring hash value matching the second specific hash value.
When the input data includes the ID issued at the time of registering the shareholder list file, the value assigned to the leaf node corresponding to the ID in the existing generated muckree may be set to the second specified hash value. In the example shown in Figs. 3 and 4, the ID may be a unique ID.
For the second specific hash value, the description of the first specific hash value described above can be applied equally. That is, the operation of the second specific hash value and the at least one neighbor hash value can be performed by various functions. Since this has been described above, the explanation is omitted.
In this case, the calculation of the second specific hash value and the at least one neighbor hash value may be performed through a merkle tree. Once the verification request associated with the shareholder list file is obtained, the
The second representative hash value may be at least one other hash value that matches the second specific hash value and the second specific hash value in a merge tree assigned to a particular leaf node. Can be generated by computing a hash value assigned to a leaf node.
When a service is performed using a database (for example, a block of virtual money) not managed by the
In this case, when a verification request related to the shareholder list file is obtained, the
Meanwhile, the predetermined transaction ID may be provided in the input data. That is, the user inputs a transaction ID together with either (i) the shareholder list file, (ii) the message digest for the shareholder list file, or (iii) the ID issued at the time of registering the shareholder list file, To the server (100).
In the verification operation, the
If the root value of the finally generated muck tree or the processed value corresponds to the value obtained by processing the first representative hash value or the first representative hash value included in the OP message, And can help judge or judge that the verification associated with the file has been made.
As described above, in the present invention,mWhen a merge tree with (= N) leaf nodes is created, the height of the merge tree (lognN = m), so that the integrity of the transaction can be confirmed quickly.
Meanwhile, when obtaining the input data, the
Hereinafter, a verification process will be described with reference to a concrete example shown in FIG.
Referring again to FIG. 3, when there is a verification request for
Hereinafter, a method of recording stock ownership transfer according to an embodiment of the present invention will be described. However, the description overlapping with the above embodiment will be omitted.
