The token transmission unit 113 receives a process processing request for presenting the gold held by the first member to the second member, the other, from the member terminal 130 of the first member, which is one of the plurality of members. Upon receipt, the first digital gold token corresponding to the gold asset information held by the first member is extracted from the gold information database 112 and transmitted to the member terminal 130 of the first member.

At this time, according to one embodiment of the present invention, the member terminal 130 of the first member is the first digital gold corresponding to the asset information on the gold held by the first member from the gold asset management server 110 . When the token is received, the digital signature value included in the first digital gold token is decrypted with the public key distributed in advance to the member terminal 130 of the first member, and the value contained in the first digital gold token. When it is confirmed that the hash values for the data of the asset information match each other, the verification complete message is generated indicating that the verification of the first digital gold token is completed, and then the verification is performed. A completion message may be transmitted to the gold asset management server 110 .

When the verification complete message indicating that verification of the first digital gold token is completed is received from the member terminal 130 of the first member, the asset information providing unit 114 receives the first digital gold token from the gold information database 112 . Asset information on gold held by the member is extracted and transmitted to the member terminal 130 of the first member.

That is, the asset information providing unit 114 transmits information about the gold held by the first member to the member terminal 130 of the first member only when the verification complete message is received from the member terminal 130 of the first member. By transmitting asset information, it can contribute to increasing the stability of gold trading.

In this way, when the first member's member terminal 130 receives asset information on gold held by the first member, the first member allows the first member through the first member's member terminal 130 . View the asset information on the gold held, and designate a first weight that is enough to present gold to the second member, and then display the information about the gold held by the first member to the member terminal 130 of the first member. The first weight may be input, and in this case, the member terminal 130 of the first member uses the gold asset management server 110 to provide gold corresponding to the first weight with respect to the gold held by the first member. You can send a gift request.

The gift request approval unit 115 instructs the first member to gift the second member with gold corresponding to a first weight of the gold held by the first member from the member terminal 130 of the first member. When the request is received, after authentication of the member terminal 130 of the first member is performed, the first member from asset information on gold held by the first member stored in the gold information database 112 . It is checked whether the weight of the gold held by the first member exceeds the first weight, and if it is confirmed that the weight of the gold held by the first member exceeds the first weight, approval of the gold gift request is requested. process done

When the approval of the gold gift request is completed, the asset update unit 116 determines that the first member holds the gold asset information stored in the gold information database 112 on the gold held by the first member. By subtracting the weight of the gold by the first weight, the asset information on the gold held by the first member is updated, and the second member holds from the asset information on the gold held by the second member. By increasing the weight of the gold by the first weight, the asset information of the gold held by the second member is updated.

Hereinafter, operations of the token transmission unit 113 , the asset information provision unit 114 , the gift request approval unit 115 , and the asset update unit 116 will be described in detail as an example.

First, when a process processing request for gifting gold held by the first member to a second member is received from the member terminal 130 of the first member, which is one of the plurality of members, the token transmission unit 113 may extract the first digital gold token corresponding to the gold asset information held by the first member from the gold information database 112 and transmit it to the member terminal 130 of the first member.

In relation to this, when the first member and the second member are referred to as 'Member 1' and 'Member 2' in the gold information database 112 as shown in Table 1, the token transmission unit 113 may From the same gold information database 112, 'Digital Gold Token 1' corresponding to 'Gold Weight: 100g', which is asset information on gold owned by 'Member 1', is extracted and the member terminal 130 of 'Member 1' ) can be transmitted.

At this time, when the 'digital gold token 1' is received from the gold asset management server 110, the member terminal 130 of 'member 1' converts the electronic signature value included in the 'digital gold token 1' to that of 'member 1'. When it is confirmed that the value decrypted with the public key distributed in advance in the member terminal 130 and the hash value of the asset information data included in 'Digital Gold Token 1' match each other and both values match each other , after generating a verification completion message indicating that verification of 'digital gold token 1' is completed, the verification completion message may be transmitted to the gold asset management server 110 .

In this way, when the verification completion message indicating that verification of the 'digital gold token 1' is completed is received from the member terminal 130 of 'member 1', the asset information providing unit 114 provides gold information as shown in Table 1 above. 'Weight of gold: 100 g', which is asset information on gold owned by 'Member 1', may be extracted from the database 112 and transmitted to the member terminal 130 of 'Member 1'.

At this time, when asset information on gold held by 'Member 1' is received in the member terminal 130 of 'Member 1', 'Member 1' is 'Member 1' through the member terminal 130 of 'Member 1'. By looking at the asset information of gold held by '1', it is possible to designate a first weight that is sufficient to present gold to 'member 2', and at this time, 'member 1' can present gold to 'member 2'. When '30g' is inputted to the member terminal 130 of 'Member 1' as the first weight equal to the weight, the member terminal 130 of 'Member 1' is charged with respect to the gold held by 'Member 1'. A gold gift request corresponding to the first weight of '30 g' may be transmitted to the gold asset management server 110 .

In this way, a gold gift instructing from the member terminal 130 of 'Member 1' to present to 'Member 2' gold corresponding to the first weight of '30g' with respect to the gold held by 'Member 1' When the request is received, the gift request approval unit 115 authenticates the member terminal 130 of the 'member 1', and then the 'member 1' stored in the gold information database 112 as shown in Table 1 above. In the asset information of gold held by ', it may be checked whether '100g', which is the weight of gold held by 'member 1', exceeds the first weight of '30g'.

At this time, since '100g', which is the weight of gold held by 'Member 1', exceeds the first weight of '30g', the gift request approval unit 115 may complete the approval of the gold gift request. can

In this way, when the approval of the gold gift request is completed, the asset update unit 116 selects the gold asset information held by 'Member 1' stored in the gold information database 112 as shown in Table 1 above. By deducting '100g', the weight of gold held by 'Member 1' by '30g', the first weight, asset information on gold held by 'Member 1' can be updated as shown in Table 2 below. can

Thereafter, the asset update unit 116 determines the weight of gold held by 'Member 2' in the asset information on gold held by 'Member 2' stored in the gold information database 112 as shown in Table 1 above. By increasing '50g', which is the first weight, by '30g', which is the first weight, asset information on gold held by 'member 2' may be updated as shown in Table 2 below.

Member identification information asset information for gold digital gold token Member 1's member identification information Weight of gold: 70g Digital Gold Token 1 Member identification information of Member 2 Weight of gold: 80 g Digital Gold Token 2 ... ... ...

At this time, according to an embodiment of the present invention, the gold asset management server 110 may further include a token update unit 117 .

The token update unit 117 is updated when the asset information on gold held by the first member and the asset information on gold held by the second member are updated by the asset update unit 116 . A first hash value is generated by applying data of asset information about gold held by a first member as an input to the hash function, and a first electronic signature value is generated by encrypting the first hash value with the private key, , the first digital gold corresponding to the asset information of the first member stored in the gold information database 112 after generating a second digital gold token including the first hash value and the first electronic signature value The token is replaced with the second digital gold token, and the updated data of asset information on gold held by the second member is applied as an input to the hash function to generate a second hash value, and the second hash The value is encrypted with the private key to generate a second digital signature value, and a third digital gold token including the second hash value and the second digital signature value is generated and stored in the gold information database 112 . A digital gold token corresponding to the asset information of the second member is replaced with the third digital gold token.

For example, according to the above-described example, when the asset information on gold held by 'Member 1' is updated by the asset update unit 116, the token update unit 117 is updated as shown in Table 2 above. A first hash value is generated by applying data of asset information about gold held by member 1' to the hash function as an input, and the first hash value is encrypted with the private key to generate a first electronic signature value, , after generating 'digital gold token 3', which is a second digital gold token including the first hash value and the first electronic signature value, 'member 1' stored in the gold information database 112 as shown in Table 2 above. 'Digital Gold Token 1', which is a digital gold token corresponding to the asset information of ', may be replaced with 'Digital Gold Token 3', which is the second digital gold token, as shown in Table 3 below.

In addition, the token update unit 117 applies the updated data of asset information on gold held by 'member 2' to the hash function as an input to generate a second hash value, and uses the second hash value as the input to the hash function. A second digital signature value is generated by encryption with the private key, and 'Digital Gold Token 4', which is a third digital gold token including the second hash value and the second digital signature value, is generated, and then gold as shown in Table 2 above. 'Digital Gold Token 2', which is a digital gold token corresponding to the asset information of 'Member 2' stored in the information database 112, is referred to as 'Digital Gold Token 4', which is the third digital gold token, as shown in Table 3 below. Can be replaced.
