The user account opening unit is used for collecting enterprise information of a user to be subjected to account opening, and takes a provider C14 as an example in the examples of fig. 1 and 2;
the account opening setting unit is used for generating a secret key pair associated with the user and setting the operation authority of the secret key pair for an account of the user, so that account information is submitted to the affiliated blockchain to generate an account blockchain address corresponding to the user and broadcast the account blockchain address to all nodes of the blockchain;
a user operation unit for submitting an asset information change request of the account to the asset information recording unit in response to a user operation;
the asset information recording unit submits an asset information change request, an account blockchain address, a key pair and an associated user account blockchain address corresponding to asset change of the user to the blockchain, so that the blockchain returns a change identification to the asset information recording unit, and the asset information recording unit records the asset information change;
the asset information querying unit is configured to query the asset information modification in response to input of a modification identifier.
Wherein the asset change includes asset registration, asset transfer, etc., i.e., operations corresponding to creation, addition and deletion, change, etc., of asset information. Such as asset changes between suppliers 12 and 14 due to purchasing transactions.
Preferably, the key pair is generated by an RSA encryption procedure.
The RSA encryption algorithm is fast, the characteristic that the RSA encryption algorithm is difficult to crack is utilized to encrypt and encode the complete authentication process, and then the encoding is added into the blockchain, so that the openness of the whole process is ensured, the privacy of a user is ensured, and meanwhile, the repudiation problem is avoided.
Furthermore, the RSA encryption algorithm encrypts a plaintext generated in the authentication process by using a public key of the user, and can only decrypt by using a private key of the user to acquire the information of the whole authentication process.
By using blockchain technology, it can be ensured that asset information is not tampered with, and user 14 can monitor changes to the asset through asset change identification, such as transaction ID. Other associated users, such as the warranty 16, the provider 12, may also provide asset change information from the system when needed.
In a preferred embodiment, the blockchain may selectively send the change identification to an associated user account through which the associated user can query the asset change information as soon as logging into his own account, while the information is truly valid and tamper-proof due to the blockchain technology.
In a preferred embodiment, the account opening setting unit sets a plurality of key pairs for the same account, wherein the plurality of key pairs correspond to different account operation rights.
This mainly considers that an enterprise creates an account, modifies enterprise information and modifies asset information, these operations often need to be handled by different people, and different people have different rights, for example, the rights to create an account, in the system, the threshold value is set to 10, and only if the threshold value exceeds 10, the rights to create an account can be provided.
In general, the key pair generated for the user is kept by the user, and in the embodiment of the invention, the key pair is stored in the database of the system to facilitate unified management because the use condition of paying money needs to be paid attention to as a guarantee manager of paying money.
Next, still taking provider 14 as an example, the processes of opening an account, asset linking, asset transfer, and asset querying, respectively, will be described.
