Description

[Technical field]

[0001] The present invention relates to a management device for an electronic commerce site. [Background technology]

[0002] Crypto assets are becoming more popular and used as a currency in emerging markets, in demand for remittances, and as a means of storing value instead of gold. Even if the use of crypto assets in Japan is limited, the value of crypto assets is expected to rise in the long term as their use expands in the global market. In Japan, the exemption from tax on end-of-period valuation gains on self-issued tokens on blockchains such as crypto assets has been in place since 2023. This has begun to create an environment for token issuance in Japan. Therefore, it is believed that the expansion phase of blockchain in Japan is about to begin.

[0003] Regarding smart contracts realized on the blockchain, smart contract networks can realize management and services of tokenized financial products at a fraction of the cost of traditional finance. Therefore, it is expected that token issuance by large companies, local governments, and NPOs will become more widespread in Japan in the future. Therefore, the cryptocurrency economy is expected to become widespread as a new means of fundraising and an economy that replaces points. In the global market, tokenization of financial assets is expected to popularize self-custody, where token assets are stored in wallets to which the private key is held. This is expected to accelerate the transition of financial assets to blockchain.

[0004] Incidentally, electronic commerce transactions in which settlement is made using crypto assets on a blockchain require access to a wallet in which the crypto assets are stored. To maintain high security, access to the wallet is usually restricted by authentication using a corresponding cryptographic key. Therefore, if a user cannot access the cryptographic key, the user cannot access the wallet to perform the above-mentioned electronic commerce transactions. Examples of situations in which the cryptographic key cannot be accessed include a situation in which the cryptographic key is stored in a specific device and the device is not at hand. Due to these circumstances, there is a demand for a means to improve user convenience in transactions using a blockchain, such as authentication in electronic commerce transactions in which settlement is made using crypto assets.

[0005] Regarding a means for improving the convenience of users in transactions using blockchain, Patent Document 1 discloses a proposed evaluation system that performs authentication using user identification information such as user ID and password stored in a user information DB realized by a distributed ledger such as blockchain or other means, SNS linked authentication, etc. The technology described in Patent Document 1 can improve security at the time of login, etc. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2021-149898 Summary of the Invention [Problem to be solved by the invention]

[0007] The blockchain in the technology described in Patent Document 1 is used to realize a user information DB, etc. in the proposal evaluation system, and is not intended for users of the system to make payments using crypto assets. Therefore, the technology described in Patent Document 1 only enables users to log in to the proposal evaluation system by authentication using a password, etc., SNS linked authentication, etc. Therefore, the technology described in Patent Document 1 has room for further improvement in terms of increasing the convenience of users in transactions using the blockchain, such as authentication in electronic commerce where payments are made using crypto assets.

[0008] The present invention has been made in consideration of the above circumstances. An object of the present invention is to improve the convenience of transaction participants in electronic commerce where settlement is made using crypto assets. [Means for solving the problem]

[0009] As a result of intensive research into solving the above problems, the inventors have found that the above object can be achieved by enabling a user who has been authenticated using either a password, an external authentication server, or a cryptographic key of a crypto-asset wallet to make a payment using crypto-asset stored in the crypto-asset wallet. The inventors have then completed the present invention. Specifically, the present invention provides the following.

[0010] The present invention provides an e-commerce site management device comprising: a Web1 authentication unit that performs Web1 authentication, which is authentication using a password set by a user; a Web2 authentication unit that performs Web2 authentication, which is authentication using social authentication information that is information indicating successful authentication of the user sent from an external authentication server; a Web3 authentication unit that performs Web3 authentication, which is authentication using a cryptographic key of a cryptocurrency wallet owned by the user; an authentication management unit that manages the correspondence between two or more of the Web1 authentication, the Web2 authentication, and the Web3 authentication for each user; and a payment unit that makes payment using cryptocurrency stored in the cryptocurrency wallet in response to instructions from an authenticated user who is a user authenticated by the Web1 authentication, the Web2 authentication, and / or the Web3 authentication.

[0011] Regarding the improvement of the convenience of authentication in electronic commerce where payment is made using crypto assets, the improvement of the convenience of authentication associated with payment can be mentioned. When electronic commerce where payment is made using crypto assets on a blockchain only performs authentication using the cryptographic key of a crypto asset wallet, the cryptographic key is stored in a specific device, and the user cannot make the payment in a situation where the device is not at hand. On the other hand, in authentication using a password, the user cannot make the payment in a situation where the password is forgotten. Also, in authentication using an external authentication server such as Google Authentication System (registered trademark) or Facebook Integration (registered trademark), the user cannot make the payment in a situation where the authentication server is unavailable. Therefore, there is a demand for an improvement in convenience that allows authentication associated with payment to be performed even in these situations.

[0012] In the present invention, the Web1 authentication unit performs authentication using a password (Web1 authentication). Also, in the present invention, the Web2 authentication unit performs authentication using an external authentication server (Web2 authentication). Furthermore, in the present invention, the Web3 authentication unit performs authentication using the encryption key of the cryptocurrency wallet (Web3 authentication). And, in the present invention, the payment unit enables a user (authenticated user) authenticated by either Web1 authentication, Web2 authentication, or Web3 authentication to make payment using cryptocurrency stored in the cryptocurrency wallet.

[0013] That is, the present invention enables a user to perform electronic commerce using crypto assets for payment even in difficult authentication situations where any two of the following situations occur simultaneously: the user has forgotten his / her password, the user is unable to use the authentication server, and the user is unable to use the device on which the encryption key of the wallet is stored. As a result, the present invention can improve the convenience of users regarding authentication in electronic commerce using crypto assets for payment. That is, the present invention can improve the convenience of users who are transaction participants in electronic commerce using crypto assets for payment. Effect of the Invention

[0014] The present invention can increase convenience for transaction participants in electronic commerce where payments are made using crypto assets. [Brief description of the drawings]

[0016] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0017] <System S> 1 is a block diagram showing the hardware configuration of a system S according to this embodiment. The electronic commerce system (system S) according to this embodiment is configured to include at least a management device 1 of an electronic commerce site that communicates with a terminal T via a network N. In order to provide participants with the convenience of increasing the value of NFTs without having to expend effort on the manufacture of devices for cryptocurrency mining, it is preferable that the system S is further configured to include a cryptocurrency mining device 2 that communicates with the management device 1 via the network N.

[0018] [Management device 1] The management device 1 includes a control unit 11, a memory unit 13, a communication unit 14, etc. The type of the management device 1 is not particularly limited. The type of the management device 1 may be, for example, various types of servers, cloud servers, etc. The management device 1 participates in a blockchain via a network N. The management device 1 is capable of communicating with an external authentication server (not shown) via the network N.

[0019] [Control unit 11] The control unit 11 includes a Central Processing Unit (CPU), a Random Access Memory (RAM), and a Read Only Memory (ROM).

[0020] The control unit 11 cooperates with the storage unit 13 and / or the communication unit 14 as necessary. The control unit 11 then realizes the software components of the program of this embodiment executed by the management device 1. The software components include an authentication management unit 111, a Web1 authentication unit 112, a Web2 authentication unit 113, a Web3 authentication unit 114, a game token granting unit 115, a settlement unit 116, a reward granting unit 117, a fee granting unit 118, an application acceptance unit 119, a shipping command unit 120, an NFT granting unit 121, a first value granting unit 122, a second value granting unit 123, and the like.

[0021] [Storage section 13] The memory unit 13 is a device in which data and / or files are stored, and includes a storage unit that stores data non-temporarily using a hard disk, a semiconductor memory, a recording medium, a memory card, and the like.

[0022] The storage unit 13 may have a mechanism that enables connection via the network N to a storage device or storage system such as a Network Attached Storage (NAS), a Storage Area Network (SAN), cloud storage, a file server, and / or a distributed file system.

[0023] The memory unit 13 stores a program executed by the CPU, a user database 131, reward award conditions, reward award rates, fee award conditions, fee award rates, and criteria for assigning value to participants' NFTs in projects using crowdfunding.

[0024] (User database 131) The user database 131 stores correspondence between two or more of Web1 authentication, Web2 authentication, and Web3 authentication. Here, Web1 authentication, Web2 authentication, and Web3 authentication are as follows: Web1 authentication is authentication using a password set by the user. Web2 authentication is authentication using social authentication information, which is information indicating successful authentication of the user sent from an external authentication server. Web3 authentication is authentication using an encryption key of a cryptocurrency wallet owned by the user. Hereinafter, the cryptocurrency wallet will also be simply referred to as a "wallet".

[0025] In addition, the user database 131 stores information for identifying a user and authentication information related to the stored correspondence. The information for identifying a user is, for example, a uniquely determined user ID, a unique user account name, etc. The authentication information related to Web1 authentication is, for example, information for verifying a user's account name and password. The information for verifying a password is, for example, a hash value of a password. The authentication information related to Web2 authentication is, for example, a user ID in an authentication server, information for identifying an authentication server (authentication server information), and information indicating successful authentication. The authentication information related to Web3 authentication is, for example, a wallet public key, a signature made with a wallet private key, an address of a wallet on a blockchain, etc. By storing these pieces of authentication information in the user database 131, the management device 1 can perform Web1 authentication, Web2 authentication, and Web3 authentication using these pieces of authentication information. Note that the authentication information related to Web3 authentication preferably includes information for the management device 1 to perform a settlement using the cryptocurrency assigned to the wallet. As an example of such information, an address of a specific smart contract prepared for such a settlement can be given.

[0026] 2 is an example of the user database 131. In the user database 131 of this example, the correspondence between the user ID "U0001", authentication information related to Web1 authentication (account name "BitC", password hash value "c86e38817a142a511f08fbfbbc1eb8b59aa8f31d"), and authentication information related to Web3 authentication (wallet public key "public key 1", signature "signature by private key 1", wallet address "0x1ABC...", and settlement smart contract address "0x2ABC...") is stored. In addition, the user database 131 in this example stores a correspondence between the user ID "U0002", authentication information related to Web2 authentication (user ID "@Shirushi", authentication server information "SNS1 authentication", information indicating successful authentication), and authentication information related to Web3 authentication (wallet public key "public key 2", signature "signature using private key 2", wallet address "0x1DEF...", and payment smart contract address "0x2DEF...").

[0027] By storing these correspondences in the user database 131, the management device 1 can manage the correspondences between two or more of the Web1 authentication, Web2 authentication, and Web3 authentication. The management device 1 can then make payments using crypto assets stored in the crypto asset wallet to users authenticated by various authentication means, not limited to Web3 authentication.

[0029] [Cryptocurrency mining device 2] The cryptocurrency mining device 2 is a device that mines cryptocurrency. The "mining" performed by the cryptocurrency mining device 2 is a process of verifying cryptocurrency transaction records based on blockchain technology and issuing new cryptocurrency. The cryptocurrency mining device 2 verifies the legitimacy of transactions by performing complex calculations associated with the issuance of new cryptocurrency, and adds new blocks to the blockchain. The blockchain then realizes a distributed ledger system that manages cryptocurrency.

[0030] It is preferable that the cryptocurrency mining device 2 is a so-called IoT device that automatically connects to the network N. This allows the owner of the cryptocurrency mining device 2 to use the cryptocurrency mining device 2 via the network N without having to go through the complicated procedures of connecting the cryptocurrency mining device 2 to the network N himself. This also allows the cryptocurrency mining device 2 to transmit information related to the mined cryptocurrency to the management device 1 via the network N. To further reduce the effort involved in connecting to the network N, it is preferable that the cryptocurrency mining device 2 is equipped with a security function related to communications and connects to a wireless LAN network.

[0031] It is preferable that the cryptocurrency mining device 2 is manufactured by the issuer of the cryptocurrency. This is expected to result in a cryptocurrency mining device 2 that is appropriately designed and manufactured by an issuer that is familiar with the characteristics of the cryptocurrency. In order to improve the cost-effectiveness of mining, it is preferable that the economic cost of the power consumption of the cryptocurrency mining device 2 is 5 yen or less per month. The cryptocurrency mining device 2 may be attached to other electronic devices, such as lighting fixtures. This allows the cryptocurrency mining device 2 to be used as the attached electronic device even when mining rewards cannot be obtained. In addition, the cryptocurrency mining device 2 may be installed in an IoT device equipped with various sensors. This allows the cryptocurrency mining device 2 to collect a wider range of information, enabling the formation of a more effective set of information. This also contributes to the promotion of the formation of a token economy, making it possible to achieve a synergistic effect between the provision of an effective set of information and the formation of a token economy.

[0032] [Network N] The type of the network N is not particularly limited as long as it enables communication between the management device 1 and the terminals T, etc. The type of the network N is, for example, the Internet, a mobile phone network, a wireless LAN, etc.

[0051] The management process includes a series of processes related to user sign-in so that a user who has been authenticated using any of authentication using a password, authentication using an external authentication server, and authentication using the cryptographic key of the cryptographic asset wallet can make a payment using the cryptographic asset stored in the cryptographic asset wallet. Steps S7 to S10 are an example of the process.

[0052] [Step S7: Determine if sign-in was performed using Web1 authentication] The control unit 11 executes the Web1 authentication unit 112 in cooperation with the storage unit 13 and the communication unit 14. Then, the control unit 11 executes a process to determine whether the Web1 authentication unit 112 has performed sign-in by Web1 authentication, which is authentication using a password set by the user (step S7, Web1 authentication step). If it is determined that the sign-in has been performed, the control unit 11 moves the process to step S10.
