Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
FIG. 1 is a schematic diagram of the main flow of an asset management method according to an embodiment of the application, as shown in FIG. 1, which may specifically include the following steps:
step S101, receiving an asset transfer notification request sent by a first node, where the asset transfer notification request indicates asset transfer information between the first node and a second node, and information of one or more third nodes to acknowledge the asset transfer information.
The first node, the second node and the third node may be corresponding to natural persons, or may be an enterprise, an organization or the like. The asset transfer information includes a first node that is a transferor, a second node that is a transferee, and the transfer asset information involved, etc. Transfer assets include, but are not limited to, creditors, copyrights, items, and the like. Specifically, the embodiment of the application is described by taking the transfer asset as an example, and asset transfer information comprises an original creditor, namely a first node, a new creditor, a second node, a creditor transfer agreement signed by the original creditor and the new creditor, and the like; correspondingly, the liability person who needs to fulfill the obligation is the third node which needs to be informed of the right transfer information or confirm the right transfer information, and in the case that the right has a guarantor, the guarantor is the third node which needs to be informed. The information of the third node includes, but is not limited to, one or more of the following: the mobile phone number, the mailbox and the account, the identity and the like which are provided by the first node and used for contacting the third node are registered in the asset management device by the third node.
It will be appreciated that before the first node sends the asset transfer notification request to the asset management device, the first node and the second node need to complete registration at the asset management device, and the third node needs to complete registration at the asset management device, but in some special cases, the third node may be allowed to complete registration of the asset management device according to the direction of the reminding content when receiving the reminding for confirming the asset transfer notification.
In an alternative embodiment, the first node, the second node, and the third node all use distributed digital identities to register with the asset management device and pass KYC or KYB authentication.
The distributed digital identity identifier (Decentralized Identifiers, DID) is a decentralised verifiable digital identifier composed of character strings, and has the characteristics of being distributed, independently controllable, multiplexing across block chains and the like. Each entity can autonomously complete registration, resolution, updating or revocation operations of the DID, and each entity can possess multiple identities, each identity corresponding to a unique DID value and an asymmetric key pair associated therewith. In addition, the user can define the information describing the identity in the DID Document by himself, so that the DID identity can be adopted, private information which is not wanted to be public or is inconvenient to disclose by the user can be hidden, and the safety and privacy of asset transfer are considered.
KYC (Know your customer) is a personal-oriented authentication method, while KYB (Know your Business) is an enterprise-oriented authentication method. Specifically, taking the first node as a natural person to perform KYC verification as an example for explanation, the first node needs to provide information such as name, mobile phone number, identity card number, address and the like when the asset management device registers, so that the asset management device can verify the real identity of the first node through the access authority identity authentication system according to the identity information provided by the first node, and the first node is allowed to complete registration if and only if the real identity verification of the first node passes. Similarly, if the first node is an enterprise, it needs to perform kbb authentication, that is, the first node needs to provide information such as an enterprise name, a unified social credit code, a registration number or a registration address, service flow, and the like for the device when the asset management device registers, so that the asset management device verifies the true identity of the first node by accessing an authoritative identity authentication system such as a national enterprise credit information presentation system according to identity information provided by the first node, and allows the first node to complete registration if and only if the true identity of the first node passes verification.
Thus, the distributed identity identifier can be used for identifying each party identity in the asset management device to carry out asset transfer management, and meanwhile, the authenticity and the effectiveness of each party or each user in the asset management device can be ensured based on KYC or KYB authentication, so that the safety and the reliability of asset transfer are improved.
And step S102, generating an asset transfer notification according to the asset transfer information and uploading the asset transfer notification to a block chain.
Specifically, the generating asset transfer notification according to the asset transfer information and uploading the asset transfer notification to a block chain includes: generating the asset transfer notification based on the intelligent contract of the blockchain according to the asset transfer information; and issuing the asset transfer notification to the first node so that the first node encrypts the asset transfer notification by using a corresponding private key and uploads the asset transfer notification to the blockchain.
That is, asset transfer notifications may be automatically generated by predefined blockchain smart contract templates, for example, right transfer notifications, and the included information includes, but is not limited to, the original right person, the assignee, the transfer time, the debtor, the guarantor, the right itself, and the like. Further, the first node encrypts the right transfer notice by using the private key and uploads the right transfer notice to the blockchain, so that the real validity of the right transfer notice is ensured. On the basis, the credited right transfer notice uploaded to the blockchain is the credited right transfer notice encrypted by the private key of the first node, so that only a user knowing the public key of the first node can decrypt the credited right transfer notice for confirmation, and the security and the reliability of the credited right transfer notice are ensured.
It will be appreciated that the first node and the third node may exchange their public keys in an offline manner, or may send the public key of the first node to the third node via the asset management device. If the first node uploads the encrypted asset transfer notification, the asset management device may send the public key of the first node to the account of the third node according to the distributed identity Fu Dingwei corresponding to the third node provided by the first node, where the account of the third node is in the asset management device, or attach the public key of the first node when sending a message, an email, or other alert to the third node. Meanwhile, in order to facilitate the third node logging in the asset management device to confirm the asset transfer notification, the encrypted asset transfer notification may be directly issued to the account of the third node, or the hash value or the identifier corresponding to the asset transfer notification may be issued to the account of the third node, so that the third node queries the encrypted asset transfer notification from the blockchain and confirms the encrypted asset transfer notification.
Step S103, monitoring a status of the asset transfer notification on the blockchain, so as to remind the third node to confirm the asset transfer notification on the blockchain according to the information of the one or more third nodes when the status of the asset transfer notification is to be confirmed.
Specifically, by establishing an off-chain monitoring mechanism, that is, monitoring the status of the asset transfer notification on the blockchain in real time independently of the monitoring service outside the blockchain, not only can the instantaneity of the monitored asset transfer notification status be ensured, but also the interference of the monitoring service on the asset transfer notification on the blockchain can be avoided, and even if the monitoring message is intercepted or the monitoring service is attacked, the third node can still ensure the reliability of the confirmed asset transfer notification by means of inquiring the asset transfer notification through the uplink.
It will be appreciated that since there may be more than one third node to acknowledge the asset transfer information and the time points at which each third node completes the acknowledgement may be different, it is necessary to record the acknowledgement result for each third node separately and update the corresponding status of the asset transfer notification to acknowledged if and only if all third nodes complete the acknowledgement. For example, if the third node has the first node and the second node, the status of the asset transfer notification needs to be updated according to the confirmation time points of the first node and the second node, for example, the status of the asset transfer notification is updated to be confirmed when the first node and the second node are confirmed. In this process, if the status of the asset transfer notification is monitored to be confirmed, the third node that has not completed the confirmation may be further selectively reminded according to the confirmation records of the first and second nodes.
In an alternative embodiment, the third node is prompted to confirm the asset transfer notification stored on the blockchain by any one or more of: short messages, mails, telephones, messages; and the short message or the mail comprises a link for the third node to log in the asset management device to confirm the asset transfer notification.
Specifically, the third node may log in the asset management device quickly or automatically according to the link indicated in the mail or the sms under the condition that the third node receives the alert. Based on this, the third node may obtain the encrypted asset transfer notification from the blockchain according to the identifier or the hash value of the asset transfer notification indicated in the reminder, or may obtain the encrypted asset transfer notification from the blockchain according to the identifier or the hash value of the asset transfer notification issued in the asset management device account, or directly use the asset transfer notification issued in the asset management device account. In addition, the third node may query the encrypted asset transfer notification from the blockchain by using other asset transfer information, such as the DID of the first node and the DID of the third node. Further, after the third node obtains the encrypted asset transfer notification, the third node decrypts the asset transfer notification by using the public key of the first node exchanged offline, or the public key of the first node additionally sent in the reminder, or the public key of the first node already issued in the third node asset management device account, so as to confirm the asset transfer notification.
In an alternative embodiment, the method further comprises: and reminding the first node and the second node of the current state of the asset transfer notice under the condition that the asset transfer notice on the block chain is in the to-be-confirmed state for more than a threshold time. The threshold time is a valid period of the right transfer notice set according to actual conditions, such as 30 days, 15 days, and the like. That is, if the right transfer notification is not confirmed after being expired, the first node and the second node participating in the right transfer notification are reminded in time, and the third node does not confirm the right transfer notification, so that the first node and the second node can take other processing measures in time.
In an alternative embodiment, the method further comprises: receiving an asset transfer notification acknowledgement request sent by the third node, the asset transfer notification acknowledgement request indicating the asset transfer notification; and generating asset transfer confirmation information corresponding to the asset transfer notification, and uploading the asset transfer confirmation information to the block chain to update the state of the asset transfer notification to be confirmed by the third node.
Further, the generating asset transfer acknowledgement information corresponding to the asset transfer notification and uploading to a blockchain to update the status of the asset transfer notification to be acknowledged by the third node includes: generating the asset transfer acknowledgement information based on the intelligent contract of the blockchain according to the asset transfer information; and transmitting the asset transfer confirmation information to the third node, so that the third node encrypts the asset transfer confirmation information by using a corresponding private key and uploads the asset transfer confirmation information to a blockchain.
That is, asset transfer validation information may be automatically generated by a predefined blockchain smart contract template, such as creditor transfer validation information, including but not limited to the original creditor, assignee, transfer time, debtor, guarantor, creditor, etc. Further, the third party encrypts the right-of-debt confirmation information by using the private key, so that the true validity of the right-of-debt transfer confirmation information is ensured. On the basis, the credited transfer confirmation information uploaded to the blockchain is the credited transfer notice encrypted by the private key of the first node, so that only the user knowing the public key of the third node can decrypt the credited transfer confirmation information, and the reliability and the safety of the credited transfer confirmation information are further ensured.
In an alternative embodiment, the method further comprises: and storing the asset transfer notification and the asset transfer confirmation information on the block chain to other block chains for certification through a relay chain. Taking the right transfer as an example, the right transfer notification and the right transfer confirmation information are uploaded to the judicial alliance chain through the relay chain, so that the right transfer notification and the right transfer confirmation information are stored.
Based on the above embodiment, by encrypting and uploading the right transfer notice and the right transfer confirmation information to the blockchain, the storage and recording of the right transfer notice and the right transfer confirmation information which cannot be tampered are realized, and further the storage of the right transfer notice and the right transfer confirmation information can be realized. Meanwhile, the state of the asset transfer notification on the block chain is monitored in real time through the off-chain monitoring service, so that the automatic reminding of confirming the asset transfer notification on the third node deblocking chain is realized, and the notifying efficiency of the asset transfer notification is improved. In addition, the user identity of the asset management device is managed by combining a distributed identity technology with KYC and KYB authentication, so that the authenticity and the reliability of the user identity are ensured, and the safety and the privacy of asset transfer are also ensured.
Referring to fig. 2, on the basis of the implementation described above, another asset management method is provided in an embodiment of the present invention, and the method specifically includes the following steps:
step S201, receiving an asset transfer notification request sent by a first node, where the asset transfer notification request indicates asset transfer information between the first node and a second node, and information of one or more third nodes to acknowledge the asset transfer information.
Step S202, generating an asset transfer notice according to the asset transfer information and uploading the asset transfer notice to a block chain.
Specifically, generating the asset transfer notification based on the intelligent contract of the blockchain according to the asset transfer information; and issuing the asset transfer notification to the first node so that the first node encrypts the asset transfer notification by using a corresponding private key and uploads the asset transfer notification to the blockchain.
Step S203, monitor the status of the asset transfer notification on the blockchain, so as to remind the third node to confirm the asset transfer notification on the blockchain according to the information of the one or more third nodes when the status of the asset transfer notification is to be confirmed.
Specifically, the third node is prompted to confirm the asset transfer notification stored on the blockchain by any one or more of: short messages, mails, telephones, messages; and the short message or the mail comprises a link for the third node to log in the asset management device to confirm the asset transfer notification.
In addition, the first node and the second node are reminded of the current status of the asset transfer notification if the asset transfer notification on the blockchain is in a to-be-confirmed status for more than a threshold time.
Step S204, receiving an asset transfer notification acknowledgement request sent by the third node, where the asset transfer notification acknowledgement request indicates the asset transfer notification.
Step S205, generating asset transfer acknowledgement information corresponding to the asset transfer notification, and uploading the asset transfer acknowledgement information to the blockchain to update the status of the asset transfer notification to be that the third node has acknowledged.
Specifically, according to the asset transfer information, generating the asset transfer confirmation information based on the intelligent contract of the blockchain; and transmitting the asset transfer confirmation information to the third node, so that the third node encrypts the asset transfer confirmation information by using a corresponding private key and uploads the asset transfer confirmation information to a blockchain.
In step S206, the asset transfer notification and the asset transfer confirmation information on the blockchain are stored to other blockchains for certification through a relay chain.
