Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as 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.
According to one aspect of the embodiment of the invention, a system for under-chain asset hosting transfer is provided.
Fig. 1 is a schematic diagram of the main components of the system for the managed transfer of assets under the chain of the present invention. As shown in fig. 1, a system 100 for hosting transfer of an asset under chain according to an embodiment of the present invention includes: an asset hosting system 102 and an asset application terminal system 101; wherein the content of the first and second substances,
the asset application terminal system generates managed transfer request information with a user private key signature based on a managed transfer request instruction of a user, and sends the managed transfer request information with the user private key signature to the asset hosting system;
the asset hosting system verifies the user private key signature and the hosted transfer request information; after the verification is passed, sending uplink request information with the asset hosting system signature to the asset application terminal system;
the asset application terminal system verifies the uplink request information with the asset hosting system signature; after the verification is passed, signing the uplink request information with the asset hosting system signature by adopting a user private key to obtain the uplink request information with the signatures of both the user and the asset hosting system; returning uplink request information of the two-party signature to the asset hosting system;
the asset hosting system verifies the uplink request information of the two-party signature; and after the verification is passed, sending notification information to the asset application terminal system to notify the user to handle the offline asset hosting transfer.
The asset application terminal system is security software and hardware installed on the terminal equipment. The terminal device may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like.
The asset hosting system can be a system for hosting and managing the real-name registered assets under the chain by a user through a designated hosting party and for registering and managing the process of issuing the digital assets on the block chain by the hosted assets; the user may access the asset hosting system via the Web or otherwise.
The method comprises the steps that a user initiates custody transfer request information through an asset application terminal system, the asset custody system initiates uplink request information to the asset application terminal system after verification is passed, the user signs a contract and sends the contract to the asset custody system after confirming the uplink request information through the asset application terminal system, and the asset custody system informs the user of handling the offline asset custody transfer after confirming the uplink request information through the asset application terminal system so as to carry out uplink operation on the offline asset custody transfer in a subsequent custody mode.
The uplink request message corresponds to a managed uplink protocol that is sent by the asset hosting system to the user. In the invention, before the mandate uplink protocol is sent to the user, the asset mandate system firstly verifies the user private key signature and mandate transfer request information sent by the asset application terminal system. The identity of the user can be verified by verifying the private key signature of the user so as to determine whether the current operation is the operation of the user; by verifying the hosted transfer request information, the user's off-chain assets can be verified, e.g., to verify whether the off-chain assets belong to the user, as well as other registration information, such as asset registration information for the off-chain assets, stakeholder information, asset amount or quantity information, asset-related status information (e.g., whether a pledge is present, whether a flaw is present, etc.), and the like. After the mandate uplink protocol is sent to the user and before the notice information is sent to the asset application terminal system, the asset mandate system sends the uplink request information with the signature to the user for signature verification, and the subscription confirmation of the user can be ensured; after the asset application terminal system adopts a user private key to sign the uplink request information with the asset hosting system signature and sends the uplink request information with the user signature and the asset hosting system signature to the asset hosting system, the asset application terminal system indicates that the hosting uplink protocol obtains user subscription confirmation; after obtaining the user subscription confirmation, the asset hosting system verifies the uplink request information of the two-party signature sent by the user again, and can confirm whether the operation of sending the signature is the operation of the user. Therefore, the security of the process of the asset hosting transfer under the chain can be greatly improved through the bidirectional signature.
A user may download and install asset application end system software from an asset hosting system by accessing the asset hosting system. In some embodiments, before a user initiates a managed transfer request instruction to an asset application terminal system, a terminal device accesses the asset application terminal system, submits identification information according to a preset login identification mode, and logs in the asset application terminal system. And the asset application terminal system judges that the user is used as a real-name user of the account book address of the associated digital asset, and acquires a real-name account book record corresponding to the user. The real-name account book record comprises: an identity certificate associated with the identity information of the user (the identity certificate may include the identity information of the user and the public key of the user), asset ledger address information associated with the identity information of the user. The identity Certificate may be a CA (Certificate Authority) Certificate provided for the purpose of making information non-repudiation. The asset application terminal system can preset different uplink templates of the uplink-capable downlink assets for selection and input of a user, so that on one hand, the convenience of the user for sending the managed transfer request instruction is improved, and on the other hand, the asset application terminal system is convenient to capture and analyze the managed transfer request instruction of the user.
The hosted transfer request instruction may include: and (4) under-chain asset registration information, and hosting transfer asset amount or quantity. The under-link asset registration information refers to under-link asset information registered in an under-link asset right registration system by a user, such as which types of assets the user owns, the amount or quantity of each type of assets, relevant status information of the assets (e.g., whether the assets are pledged, whether flaws exist, etc.), and the like. The amount or quantity of the escrowed transfer asset refers to the amount or quantity of the asset under the chain that the user requests to escrow transfer. In an alternative embodiment, the under-link asset registration information includes: an access address of a linked asset right registration system, asset identification information; wherein the asset identification information comprises at least one of: name or identification of the righter, asset class, asset identification or number, asset amount or quantity.
The hosted transfer request information may include: and hosting an assignment request instruction and a real-name account book record of the user. The asset application terminal system sends the mandate transfer request instruction and the real-name account book record of the user to the asset mandate system as mandate transfer request information, so that the asset mandate system can verify whether the authorized person of the asset in the mandate transfer request instruction is consistent with the identity information corresponding to the real-name account book record of the user, and therefore system safety is improved.
The uplink request information may include: the method comprises the steps of escrow transfer request information with a user private key signature, escrow asset issuing information and asset escrow party information. The managed asset issuance information is issuance information when an asset under the chain is managed to the chain, and the asset hosting party information is information of an asset hosting party responsible for hosting the asset under the chain that is issued to the chain. In an alternative embodiment, hosting asset issuance information includes: managed asset class, managed asset description information, authority address, number of asset issuing units. The managed asset class may be consistent with the asset class in the asset identification information of the downlinked asset registration information of the managed transfer request instruction.
Optionally, the asset application terminal system is further configured to: before generating managed transfer request information with a user private key signature, confirming that the managed transfer request instruction is verified and passes the verification according to the following steps:
and accessing a downlink asset right registration system to acquire the downlink asset registration information of the user, and confirming that the verification is passed when the acquired downlink asset registration information of the user is consistent with the downlink asset registration information in the hosting transfer request instruction.
In some embodiments, the under-link asset entitlement registration system provides an API interface for asset entitlement verification queries. And the asset application terminal system accesses an asset right verification inquiry API interface provided by the asset right registration system under the chain and verifies the asset identification information in the managed transfer request command submitted by the user. The under-chain asset right registration system returns verification results including: whether the asset belongs to the authorized person, and other registration information, such as asset registration information, authorized person information, asset amount or quantity information, asset-related status information, and the like. If the verification is not passed, returning a user error prompt, and ending the process. And if the verification is passed, the asset application terminal system generates managed transfer request information with a user private key signature, and then sends the managed transfer request information with the user private key signature to the asset management system.
Of course, if the asset right registration system under the chain does not provide an API interface for the asset right verification query, or the asset application terminal system cannot access the asset right registration system under the chain, the asset identification information in the managed transfer request command submitted by the user may be verified in an offline manual manner.
After the asset application terminal system confirms that the verification is passed, the asset application terminal system sends escrow transfer request information with the user private key signature to the asset escrow system, and the system security can be further ensured.
Optionally, the verifying the managed transfer request information by the asset hosting system includes:
the asset hosting system verifies whether the name or identification of the authorized person in the under-link asset registration information of the hosting transfer request information is consistent with the identity information corresponding to the user identification in the real-name book record; if not, the verification fails;
otherwise, the asset hosting system sends the under-link asset registration information to an asset hosting party so as to verify the under-link asset registration information in the hosting transfer request information through the asset hosting party; when the user's offline asset registration information acquired by the asset hosting party from the offline asset right registration system is consistent with the offline asset registration information in the hosted transfer request information, returning result information of passing verification to the asset hosting system; otherwise, returning the result information of the failed verification to the asset hosting system.
For example, the asset hosting system verifies the signature of the hosted transfer request information, and verifies whether the name or identification of the authorized person in the asset identification information of the asset registration information under the chain of the asset hosting transfer request instruction is consistent with the user identity information corresponding to the user identification recorded by the real-name account book user, so as to verify whether the user operates himself or herself. And if the two are inconsistent, directly returning error information. If so, the asset escrow sends an off-chain asset registration message to the asset escrow to notify the asset escrow to verify the asset rights request of the righter. The asset hosting system can carry out online verification by accessing an asset right verification inquiry API interface provided by the asset right registration system under the chain, and the asset hosting party carries out verification in a manual mode under the condition that online verification cannot be carried out through the API interface;
the property management party accesses the property right registration system, and inquires and checks the property registration information under the chain, whether the property is owned by the right holder, whether the property has flaws, whether the property amount or quantity information possibly involved is full, and the like;
the asset hosting party returns result information of the asset hosting system for verifying the asset right according to the query and check result, and the method comprises the following steps: whether the asset belongs to the obligee, and other registration information, such as asset registration information, obligee information, asset amount or quantity information, asset-related status information, and the like;
and the asset hosting system returns verification error information if the verification fails according to the verification result returned by the asset hosting party, and returns a user error prompt if the asset application terminal system locally verifies that the user submits the asset uplink information and fails, and the process is ended. If the verification is passed, the asset hosting system returns its signed uplink request message.
The following describes an example of the process of performing the offline asset hosting transfer by using the system for performing the offline asset hosting transfer according to the embodiment of the present invention with reference to fig. 2:
