Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
FIG. 1 is a flow diagram illustrating a method for asset issuance supervision, applicable to an asset issuer, that may be executed by an electronic device, such as a computer or server, according to an exemplary embodiment. As shown in fig. 1, the method comprises the steps of:
and S1A, allocating public key addresses for the users. Firstly, a user registers or registers at an asset issuer, and the issuer allocates a private public key address to all registered users, wherein the public key address is an address in a block chain and is used for storing the digital assets of the user and the certificates generated when the digital assets are traded.
The user may extract a certificate generated by the transaction (e.g., a certificate to buy the asset, a certificate to replace the asset, etc.) into their public key address, which may be understood herein as an electronic private wallet.
S2A, using the private key of the asset issuer as the public key address signature;
and S3A, sending the signed public key address to the exchange for verifying the compliance of the user by the exchange. The exchange is specifically a secondary exchange, such as a stock exchange, a bitcoin exchange, etc. In order for the exchange to be able to verify the public key address and its signature, the public key of the issuer should also be sent to the exchange or be actively acquired by the exchange.
According to the asset issuing supervision method provided by the embodiment of the invention, the asset issuer allocates the public key address for storing the transaction certificate for the user, and uses the private key of the asset issuer to sign the public key address, and then sends the public key address to the exchange, so that the exchange can verify the compliance of the user according to whether the public key address is provided by the issuer, thereby playing a role in asset issuing supervision and improving the safety of the transaction process.
In a preferred embodiment, the compliance of the user should be verified by the asset issuer, and specifically, the step S1A includes:
S1A1, obtaining the registration information of the user, providing the user with the relevant registration content according to the rule required by the verification, and obtaining the corresponding information provided by the user, wherein the registration information comprises the relevant personal information such as income condition, practice, age and the like of the user, official certification and the like.
And S1A2, determining whether the user can pass the authentication required by supervision according to the registration information. Step S1a3 is performed when the user is able to pass the authentication required for administration, otherwise the user is denied assignment of an address.
In the present embodiment, the asset issuer verifies, based on the registration information provided by the user, whether the user can pass the authentication required by the Anti-Money Laundering (AML) rule, and whether the user can pass the authentication rule required by knowing the customer (KYC).
And S1A3, allocating public key addresses to the users. According to the preferred scheme, the compliance of the user is verified by the asset issuer, and the public key address is distributed to the user passing the related verification without the intervention of other verification organizations, so that the supervision efficiency is improved.
Fig. 2 is a flow diagram illustrating a method of asset issuance supervision, applicable to an exchange, that may be performed by an electronic device, such as a computer or server, according to an example embodiment. As shown in fig. 2, the method comprises the steps of:
S1B, receiving the public key address of the user sent by the asset issuer, wherein the public key address comprises signature information. The public key address is a special address in a block chain distributed by an issuer for a user, and is used for storing the digital assets of the user and the certificates generated when the digital assets are traded. And the public key address is signed by the private key.
And S2B, verifying whether the public key address is provided by the asset issuer according to the signature information of the public key address. Step S3B is performed when the public key address is confirmed as being provided by the asset issuer, otherwise the address is considered tampered with, prompting the issuer and the user to confirm the security of the transaction. The exchange should have obtained the public key of the issuer so that verification of the signature information with the public key can determine whether the public key address was generated by the issuer.
S3B, determining that the user possessing the public key address is a compliant user, and then allowing the user to conduct a transaction with the issuer through the exchange.
In this embodiment, once the exchange confirms that the user's public key address is provided by the correct issuer, it is determined that the user has passed the authentication required by the Anti-Money Laundering (AML) rule, and that the user has passed the authentication rule required to know the customer (KYC).
According to the asset issuing supervision method provided by the embodiment of the invention, the exchange receives the public key address, then judges whether the public key address is provided by the issuer for the user according to the signature information, if the public key address is provided by the issuer, the public key address used for storing the transaction pass certificate is distributed to the user by the asset issuer, and the signature is carried out on the public key address by using the private key of the asset issuer, so that the user is confirmed to be a compliant user, the asset issuing supervision function is achieved, and the security of the transaction process is improved.
