Detailed Description

To facilitate understanding of the aspects of the embodiments of the present application, a brief introduction of related concepts is first given as follows:

first, the blockchain technique.

The blockchain technique, also called distributed ledger technique, is an emerging technique for a plurality of computing devices to jointly participate in "accounting" (i.e. recording transaction data), and to jointly maintain a complete distributed database. The blockchain technology has been widely used in many fields due to its characteristics of decentralization (i.e., no central node), transparency of disclosure, participation of each computing device in database recording, and rapid data synchronization among computing devices.

Currently, the blockchain can be divided into: public and federation chains. Public chain refers to a blockchain that can be read by any device worldwide or a blockchain that can be used by any device to participate in a consensus verification process of a transaction. A federation chain, also called a community block chain (consortium block chains), refers to a federation formed by participating members of a specified block chain, and information about business transactions between the members is recorded in the block chain, which defines the size and right of use. The block chain in the embodiment of the present application may be a federation chain, which is described in a unified manner herein and will not be described in detail below.

Second, blockchain nodes.

The blockchain in the embodiments of the present disclosure may also be referred to as a blockchain system. The blockchain system in the embodiments of the present disclosure includes a plurality of blockchain nodes (hereinafter, may be simply referred to as nodes). The node is a device having a communication function and a storage function, such as a device storing block chain data. Each node may receive information and may generate information. Communication and data synchronization is maintained between different nodes by maintaining a common blockchain. Specifically, in the blockchain system, any node may generate new blockchain data according to data related to a transaction sent by a client, and distribute the new blockchain data to other nodes in a broadcast manner, and the other nodes may verify the blockchain data. When all nodes in the blockchain system agree, new blockchain data can be added to the blockchain.

Alternatively, the node in the embodiments of the present disclosure may be understood as a processing unit. In one implementation, a node may be a physical device, such as a server or a computer. In another implementation, the node may be a virtual computer; the virtual machine is a general term for a running environment virtualized by software in all types of virtualization devices, and the concept includes a virtual machine and a container. In other implementations, a node in embodiments of the present disclosure may be a process or a thread; the thread is the minimum unit which can be operated and scheduled by the operating system, is contained in the process and is the actual operation unit in the process; a process is a running activity of a program in a computer on a certain data set, and is a basic unit for resource allocation and scheduling of a system.

And thirdly, managing the asset information.

Asset information in embodiments of the present disclosure includes asset income data and asset expenditure data for a user. Currently, asset information is primarily stored and managed by asset management authorities (e.g., banks, third party payment authorities).

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).

The embodiment of the disclosure provides an asset information management method based on a block chain, wherein the block chain is provided with a plurality of nodes, and the asset information management method is applied to N nodes in the plurality of nodes. For the nth node of the N nodes, the asset management method comprises the following steps: in response to a first instruction of the asset management authority, the asset information of the customer is updated to obtain first asset information. When N is more than or equal to 2 and less than or equal to N-1, the following steps are executed: responding to a second instruction of the (n-1) th node, combining the first asset information of the 1 st node to the (n-1) th node with the first asset information in the node to obtain second asset information; judging whether the second asset information in the node has the first asset information of each of the N nodes, if so, issuing the second asset information of the node to each of the N nodes; if not, sending a second instruction to the (n + 1) th node; wherein N and N are both positive integers.

With the asset information management method according to the embodiment of the present disclosure, N nodes generate second asset information in order, and for an nth node, the second asset information is obtained by combining (e.g., merging) first asset information in the first node to the nth node. Therefore, when any node judges that the second asset information of the node has the first asset information of each of the N nodes, the node determines that the node summarizes the asset information of the client in all the nodes, and at this time, the node distributes the second asset information of the node to other nodes so as to synchronize the N nodes. Therefore, when a client accesses any one of the N nodes, the summary of the asset information of the client in all asset management organizations can be obtained, and the summary of the asset information of the cross-organization is realized.

The client can access the nodes of the blockchain in the server 105 through the asset management APP program to query the asset information of the client on the current day. For example, a customer may make a look at his total assets and total liabilities in all asset management organizations, as well as his total assets and total liabilities in a certain asset management organization. Wherein the user may also view details of the total assets and total liabilities, such as financial balances, credit card outstanding amounts, stock market values, etc.

When using the asset management APP, the client can perform real-name registration through the identity card, and the registration information is respectively stored in the asset management mechanism and the main node of the blockchain. And establishing a mapping relation between the registration information of the client and the asset information of the client in each node through the identity card number of the client.

The client can establish mutual trust relationship with the appointed people, such as family, at the moment, the asset information between the client and the family can be merged to realize the family asset summary. In the embodiment of the present disclosure, the manner of establishing the mutual trust relationship is not particularly limited, and for example, the mutual trust relationship may be established by an identity authentication manner such as face recognition.

The server 105 may be a server providing various services, such as a background management server (for example only) providing support for websites browsed by users using the

terminal devices

101, 102, 103. The background management server may analyze and perform other processing on the received data such as the user request, and feed back a processing result (e.g., a webpage, information, or data obtained or generated according to the user request) to the terminal device.

It should be noted that the asset information management method provided by the embodiment of the present disclosure may be generally executed by the server 105. Accordingly, the asset information management device provided by the embodiments of the present disclosure may be generally disposed in the server 105.

The asset information management method of the disclosed embodiment will be described in detail through fig. 3 to 7 based on the scenarios described in fig. 1 and 2.

It should be noted that the asset information management method according to the embodiment of the present disclosure is applied to N of a plurality of nodes of a block chain, where each of the N nodes corresponds to one asset management mechanism, and different nodes correspond to different asset management mechanisms. Each of the N nodes can execute the asset information management method according to the embodiment of the present disclosure, and the embodiment of the present disclosure describes the asset management method according to the embodiment of the present disclosure by taking the nth node of the N nodes as an example, where N and N are positive integers. FIG. 3 schematically shows one of the flow diagrams of an asset information management method according to an embodiment of the disclosure. As shown in fig. 3, the asset management method includes steps S210 to S260.

First, the asset management authority sends a first instruction to a node corresponding to the asset management authority.

In the disclosed embodiment, the asset management authority may periodically send the first instruction to the node corresponding thereto, for example, the asset management authority sends the first instruction to the node corresponding thereto every day.

In step S210, the nth node updates the asset information of the client in response to a first instruction of the asset management authority to obtain first asset information.

In the embodiment of the present disclosure, the nth node may store asset information of a customer in a day, and when receiving a first instruction from an asset management authority, the nth node may obtain the asset information of the customer in the day and update the asset information of the previous day, thereby obtaining the first asset information.

In this embodiment of the present disclosure, the blockchain may be a federation chain, where the federation chain further includes a master node, the master node may sort the N nodes after the N nodes all complete step S210, and the N nodes perform step S220 after the master node completes the sorting.

In step S220, the nth node determines the serial number of the node in the N nodes, i.e. determines the size of N, and when N is greater than or equal to 2 and less than or equal to N-1, step S230 is executed.

In step S230, the nth node responds to the second instruction of the (n-1) th node, and combines the first asset information of the 1 st to the (n-1) th nodes with the first asset information in the node to obtain second asset information.

In the embodiment of the present disclosure, the first asset information of the 1 st node to the n-1 st node may be merged with the first asset information in the node to obtain the second asset information.

For example, taking N as 3 as an example, the first asset information of the client is B in the 1 st node, C in the 2 nd node, and D in the 3 rd node. Then the second asset information generated by the 3 rd node is B + C + D. It should be noted that, in the embodiment of the present disclosure, when the 3 rd node generates the second asset information, not only the first asset information in the 1 st node to the 3 rd node is added, but also a part of information of the first asset information in the 1 st node to the 3 rd node may be removed by the 3 rd node, for example, the cross-row transfer information of the customer, which will be specifically described below in detail, and is not described herein again.

In step S240, the nth node determines whether the second asset information in the node has the first asset information of each of the N nodes, and if yes, step S250 is executed; if not, go to step S260.

In step S250, the nth node issues second asset information of the present node to each of the N nodes;

in step S260, the nth node sends a second instruction to the (n + 1) th node.

In the embodiment of the present disclosure, when the nth node determines that the second asset information of the nth node has the first asset information of each of the N nodes, it is determined that the nth node summarizes the asset information of the client in all the nodes, and at this time, the nth node distributes the second asset information of the nth node to other nodes, so that the N nodes are synchronized. Therefore, when a client accesses any one of the N nodes, the summary information of the asset information of the client in all organizations can be obtained, and therefore the cross-organization asset summary is achieved. When the nth node judges that the second asset information of the nth node lacks the first asset information of a certain node, the nth node determines that the node does not complete the summary, and at this time, the nth node sends a second instruction to the next node, and the next node executes the steps S220 to S260.

The asset information management method of the embodiment of the present disclosure is described below by taking an example of a complete summary process performed by N nodes on asset information of one client. Fig. 4 schematically shows a second flowchart of an asset information management method according to an embodiment of the present disclosure, fig. 5 schematically shows a third flowchart of an asset information management method according to an embodiment of the present disclosure, and fig. 6 schematically shows a fourth flowchart of an asset information management method according to an embodiment of the present disclosure, and in conjunction with fig. 4 to 6, first, an asset management entity sends a first instruction to a node corresponding thereto. In the embodiment of the disclosure, when sending the first instruction to the node corresponding to the asset management mechanism, the asset management mechanism may send the stored asset information of the current day of the client to the node.

Optionally, the asset management entity encrypts the asset information in sending the asset information, and the encryption manner in the embodiments of the present disclosure is not particularly limited, for example, the encryption manner may use a symmetric encryption algorithm or an asymmetric encryption algorithm, and for example, the embodiments of the present disclosure may use an asymmetric encryption algorithm. In the asymmetric encryption technology, two keys are provided, namely a private key and a public key, wherein the private key is held by a key pair owner and cannot be published, and the public key is published to others by the key pair owner. Wherein the public key is used to encrypt data, and data encrypted with the public key can only be decrypted using the private key. The private key is used to decrypt the public key encrypted data. The digest is a hash of the data to be transmitted, for example, a Secure Hash Algorithm (SHA) is generally used for the hash. After receiving the transmitted data, the data receiving end needs to determine whether the data is the data sent by the data sending end and whether the data is tampered in the middle. Therefore, the received data is decrypted by the private key held by the user (the data encrypted by one key in the key pair can be decrypted by using the other key) to obtain the digest of the data, then the digest value of the received data is calculated by using the same hash algorithm as that of the data sending end, and then the comparison is carried out with the decrypted digest, and if the two are completely consistent, the text is not tampered.

In step S310, the nth node updates the asset information of the client in response to a first instruction of the asset management authority to obtain first asset information.

In this step, the nth node may update the asset information sent by the asset management authority over the asset information currently stored by the nth node, so as to obtain the first asset information.

In some embodiments, after step S310, the asset information management method further includes step S370.

In step S370, the first asset information is sent to other nodes of the N nodes for backup.

In the embodiment of the present disclosure, the number of nodes for performing backup may be determined according to actual needs, and is not limited herein, for example, 2. The node for backup may be determined according to actual needs, and the embodiment of the present disclosure is not limited, for example, the node for backup may be a fixed number of preset nodes, or may be a number of randomly set nodes.

In this embodiment of the present disclosure, the blockchain may be a federation chain, where the federation chain further has a master node, the master node may sort the N nodes after the N nodes all complete step S310, and the N nodes perform step S320 after the master node completes the sorting.

In step S320, the nth node determines the sequence number of the node in the N nodes, that is, determines the size of N, and if N is equal to 1 (that is, the node is the 1 st node), steps S330 to S334 are performed; when N is more than or equal to 2 and less than or equal to N-1 (namely the node is the 2 nd to the N-1 st node), executing the steps S341 to S343; when N is equal to N (i.e., the node is the nth node), steps S351 to S353 are performed.

First, the 1 st node performs step S331.

In step S331, the 1 st node sends a second instruction to the (n + 1) th (i.e., 2 nd) node.

In the embodiment of the present disclosure, before step S331, the 1 st node may first perform step S330.

In step S330, the first asset information is signed to obtain third asset information.

In the disclosed embodiment, step S331 includes step S3311.

In step S3311, the 1 st node sends the second instruction and the third asset information of the node to the 2 nd node. At this time, the first node enters a waiting state until receiving the second instruction of the nth node.

In the embodiment of the present disclosure, an asymmetric encryption algorithm may be used for signing, for example, a private key is used to encrypt a digest of data to be transmitted, and an obtained ciphertext is the third asset information. After receiving the transmitted data, the data receiving end decrypts the received signature by taking the own public key to obtain the abstract of the data, then calculates the abstract value of the received data by using the same Hash algorithm as that of the data sending end, and compares the abstract value with the abstract value obtained by decryption, if the two are found to be completely consistent, the text is not tampered.

After that, the 2 nd node performs step S341.

In step S341, the 2 nd node responds to the second instruction of the (n-1) th node (i.e., the 1 st node), and combines the first asset information of the 1 st node to the (n-1) th node with the first asset information of the local node to obtain the second asset information of the local node.

In the embodiment of the present disclosure, the 2 nd node may acquire the first asset information of the 1 st node in multiple ways, for example, the 2 nd node may actively acquire the first asset information from the 1 st node, or passively accept the first asset information from the 1 st node. For example, when the 2 nd node actively acquires the first asset information from the 1 st node, specifically, the 2 nd node sends an asset information request instruction to the 1 st node, and the 1 st node sends the stored first asset information to the nth node when receiving the asset information request instruction.

In the embodiment of the present disclosure, as shown in the foregoing, the 1 st node may send the third asset information while sending the second instruction to the 2 nd node, where the third asset information is obtained after being signed by the first asset information, and therefore, the 2 nd node does not need to actively obtain the first asset information of the 1 st node. Specifically, step S341 includes step S3411.

At step S3411: and the nth node combines the third asset information of the (n-1) th node with the first asset information in the node to obtain the second asset information of the node.

In some embodiments, the third asset information includes at least one asset income record and at least one asset expense record of the customer, and the asset management institution to which the income per asset record and the expense per asset record correspond; step S3411 includes:

for an asset income record and an asset expenditure record of the same client, when the two records respectively correspond to two asset management mechanisms and the amount of the asset income record is the same as the amount of the asset expenditure, the client performs a transfer step in the two asset management mechanisms, although the process causes the change of the asset information of the client, the total amount of the asset of the client does not change, therefore, the asset income record and the asset expenditure record can be deleted, and the storage space is saved.

After that, the 2 nd node performs steps S342 to S343.

In step S342, the 2 nd node signs the second asset information in the local node to obtain third asset information.

In step S343, the 2 nd node determines whether the second asset information in the node has the first asset information of each of the N nodes, and if yes, step S360 is executed; if not, go to step S344.

In some embodiments, step S343 includes step S3431

In step S3431, the 2 nd node determines whether the third asset information in the node has the signature of each of the N nodes, and if so, confirms that the second asset information in the node has the first asset information of each of the N nodes.

In the embodiment of the present disclosure, since the N nodes can obtain the third asset information thereof through the signature, each node can also determine whether the summary process is completed by determining whether the generated third asset information has the signature of each of the N nodes.

In some specific embodiments, after step S3431, the asset information management method may further include the steps of: when the first asset information of any one of the 1 st node to the n-1 st node is absent in the second asset information of the node and the first asset information of the missing node is backed up in the node, combining the backed-up first asset information of the missing node in the node with the current second asset information of the node to obtain the final second asset information of the node.

In the embodiment of the present disclosure, when it is determined that the signature of any one of the 1 st node to the n-1 st node is absent in the third asset information in the node, it is determined that the node lacks the first asset information of the node. At this time, it may be determined whether the node has the first asset information backed up, and if so, the current second asset information of the node is supplemented with the first asset information backed up by the node to obtain final second asset information, and the final second asset information is signed to obtain final third asset information of the node.

In step S344, the 2 nd node sends a second instruction to the n +1 th (i.e., 3 rd) node.

In some embodiments, step S344 may include step S3441.

In step S3441, the 2 nd node transmits the second instruction and the third asset information to the n +1 th node. At this time, the third asset information in the 2 nd node includes the first asset information of the 1 st node and the first asset information of the 2 nd node, and the signatures of the 1 st node and the 2 nd node.

When the 3 rd node receives the second instruction of the 2 nd node, the 3 rd node executes steps S341 to S343. At this time, the third asset information in the 3 rd node includes the first asset information of the 1 st node, the first asset information of the 2 nd node, and the first asset information of the 3 rd node, and the signatures of the 1 st node, the 2 nd node, and the 3 rd node.

And in analogy, the third asset information of each of the N nodes comprises the first asset information from the 1 st node to the node and the signature from the 1 st node to the node.

Until N is N. The nth node performs steps S351 to S353, wherein, as shown in fig. 5 and fig. 6, steps S351 to S353 are the same as steps S341 to S343, and thus are not described herein again.

It should be noted that, in the embodiment of the present disclosure, when the n-1 th node sends the second instruction and the third asset information to the nth node, there may be an abnormality in the nth node, which may cause the interaction between the n-1 th node and the nth node to fail. At this time, the abnormal node may be skipped and the second instruction and the third asset information may be transmitted to the (n + 1) th node. Since there is a possibility of skipping the nodes, the second asset information of the nth node lacks the first asset information of some nodes, and at this time, the nth node performs step S353 if the determination result is negative. At this time, the nth node performs step S354.

In step S354, the nth node transmits the second instruction and the third asset information of the nth node to the 1 st node.

When the 1 st node receives the second instruction of the nth node, the 1 st node performs steps S332 to S334. In the embodiment of the present disclosure, steps S332 to S334 may be obtained by referring to steps S341 to S343, and step S335 may be obtained by referring to step S344, which is not described herein again.

In this embodiment of the present disclosure, when a certain node of the N nodes can determine that the third asset information in the node includes the signature of each of the N nodes, that is, when it is determined that the second asset information in the node has the first asset information of each of the N nodes, it is determined that the summary is completed, and step S360 is executed to issue the second asset information of the node to each of the N nodes.

In some embodiments, the blockchain further includes a master node, and step S360 includes step S3611.

In step S3611, a third instruction and the second asset information of the node are sent to the master node, where the third instruction is configured to enable the master node to issue the received second asset information to the N nodes. In the embodiment of the present disclosure, the manner in which the master node issues the second asset information may be determined according to actual needs, for example, the master node may issue the second asset information by using a Gissip protocol.

In some embodiments, the master node stores the asset information of the clients in all nodes, and the master node may also be used for supporting asset graph, month and year summary functions.

In some embodiments, the master node may further issue to each node a digital certificate for the node to sign and a program update package for the node to upgrade.
