Description

Business account management method and system based on block chain
Technical Field
The present disclosure relates to the field of computer communications technologies, and in particular, to a method and a system for managing service accounts based on a block chain.
Background
With the popularization of internet technology in various industries, many services (such as social contact, games, shopping and the like) are gradually transferred from off-line to on-line, and a user can register a service account on line and participate in the services by taking the service account as an identity certificate.
It goes without saying that the business account number often condenses on the energy or money that the user continuously invests, and is often an important on-line asset for the user. For example, when a user registers a game account to play an online game, as the effort or money put into the game by the user through the game account continuously increases, the higher the level of the game account is, the more items bound to the game account are, and the greater the value of the game account is.
In practice, security issues related to the business account number cannot be ignored. For example, once the user forgets the service account or the login password corresponding to the service account, the user cannot prove the ownership of the service account. In another example, the user's business account number may be stolen by a hacker, causing a loss to the user. For another example, a user sometimes wants to sell his/her business account to another person, but cannot find a secure transaction channel.

2. The user can log in the service account number through the account number ticket in the own block chain account. Since the user's blockchain account is difficult to be hacked (the blockchain account is only controlled by the user's private key, which is very complicated and difficult to be hacked), the user's business account is also difficult to be hacked.
3. The transaction and transfer of account number tickets can be carried out between the blockchain accounts, which is equivalent to the transaction and transfer of business account numbers. Because the change of the account number ticket in any blockchain account needs to be issued to the blockchain for public notice after passing the consensus verification of each user node, and the change record of the account number ticket cannot be tampered, the change record is equivalent to a safe channel for transaction and transfer of business account numbers.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
As described above, the business account number, as an online asset of the user, faces a plurality of security problems such as easy loss, easy theft, lack of reliable transaction channel, and the like.
In order to solve the security problems related to the service account, the disclosure provides a whole set of service account management method based on the block chain, and an account ticket is issued in the block chain network by using the characteristics of an account authorization mechanism, programmability (supporting an intelligent contract), data non-falsification and the like of the block chain, and is used as a right certificate of the service account in the block chain.
It should be noted that the account number ticket described herein may be a token issued in a blockchain network and having a service account number ownership verification function. As is known, in a blockchain network, tokens can serve as virtual properties owned by blockchain accounts, and tokens can be circulated between blockchain accounts. It is worth emphasizing that the account number ticket does not have a currency attribute, but only has a mapping of the business account number in the blockchain network, and only has a business account number ownership proving function.
Thus, the user can use the token owned by the block chain account to realize the authorization of the business account, and further realize the authorization registration, authorization login, authorization transaction, authorization transfer and the like of the business account.
Through one or more embodiments of the present disclosure, the business account of the user is not easy to lose and stolen, and the user can also conveniently and safely trade the business account or transfer the business account.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Fig. 1 is a schematic flowchart of a service account registration method based on a block chain according to an embodiment of the present disclosure, which includes the following steps:
s100: and the target user node receives an account registration instruction.
In the disclosed embodiments, the blockchain network is generally built based on a public chain architecture (e.g., etherhouse). Any user can become a user node in the blockchain network by installing a blockchain program (such as an etherhouse wallet program) on own equipment (such as a computer, a mobile phone and the like) and opening an own blockchain account. That is, the user node is specifically the user's device + blockchain program + the user's blockchain account, and one user node represents one user.
In the blockchain network, each user node has a unique blockchain account corresponding to the user node, and the blockchain account has a balance (under the ethernet architecture, the balance in the blockchain account may specifically be an ethernet balance). It should be noted here that the user's blockchain account is usually controlled by the user's private key, and the user provides the user's private key to the blockchain program installed on the user node to log in the user's blockchain account, and at this time, the user has obtained control right to the user node.
For each customer node, an intelligent contract may be deployed on the customer node. The intelligent contract is essentially a piece of code for implementing the specified logic, and the user node calls the intelligent contract to implement the specified logic.
In the service account registration method shown in fig. 1, an intelligent contract deployed on each user node may be used to execute account ticket-related logic. The account ticket correlation logic may include generation logic of an account ticket, logic for assigning a ticket identity to the account ticket, logic for establishing a correspondence between the ticket identity and the account identity, and the like.
In step S100, the target user node may be any user node in the blockchain network. The account registration instruction may be issued by a target user represented by the target user node. The intention of the account registration instruction is to instruct the blockchain network to generate an account number ticket, and distribute the generated account number ticket to a blockchain account of a target user, so that a service server under a chain registers a service account number according to the account number ticket, and the binding of the account number ticket and the service account number is completed.
It should be noted that the target user generally needs to provide its own private key to the blockchain program installed on the target user node to obtain control right for the target user node, and at this time, the target user node can represent the target user and the target user can send an instruction to the target user node (for example, the target user inputs an instruction in the blockchain program installed on the target user node).
That is, the target user provides its private key to the blockchain program installed on the target user node, and then logs in its target blockchain account. In this case, the target user node, and the target blockchain account are substantially integrated.
S102: and the target user node constructs an account registration message according to the account registration instruction, and signs the account registration message through a target block chain account corresponding to the target user node.
As is well known, a message is a data structure employed for communication in a blockchain network. In step S102, the account registration message may include an account identifier of a target blockchain account corresponding to the target user node. The target node signs the account registration message through the target blockchain account (to indicate that the account registration message is authorized by the target user), specifically, the target node encrypts the digest of the account registration message by using a private key for controlling the target blockchain account to obtain a signature corresponding to the account registration message.
S104: and the target user node broadcasts the account registration message to the blockchain network.
In step S104, the target user node may broadcast the account registration message and the signature corresponding to the account registration message to a blockchain network.
S106: and aiming at each user node obtaining the account registration message, after determining that the account registration message passes signature verification, the user node generates an account ticket based on a deployed intelligent contract and establishes a corresponding relation between a ticket identifier of the account ticket and the account identifier.
In a block chain network, each user node (including the target user node) obtaining the account registration message needs to perform signature verification on the account registration message, namely, a public key corresponding to the target block chain account is used for decrypting a signature corresponding to the account registration message, if the signature is decrypted, the account registration message is authorized by the target block chain account, then, the account registration message is subjected to digest operation, and if the operation result is consistent with the result obtained by decryption, the account registration message is not tampered in the broadcasting process. Determining that the account registration message passes signature verification if the account registration message is not only authorized by the target blockchain account but has not been tampered with.
And for each user node obtaining the account registration message, after the account registration message is confirmed to pass signature verification, calling a deployed intelligent contract to generate an account ticket, and establishing a corresponding relation between a ticket identifier of the account ticket and the account identifier. This means that each user node that obtains the account registration message acknowledges that the target blockchain account has ownership of the account ticket.
S108: and the user node issues the account registration message to a block chain.
Furthermore, each user node also needs to publish an account registration message verified by a signature to the blockchain, which means that each user node is not regret upon approval for the fact that the target blockchain account has ownership of the account ticket.
S110: and the service server acquires the ticket identification from the block chain network.
In the embodiment of the present disclosure, the service server refers to a server responsible for registering a service account, managing the service account, and providing a service for a user.
The service server can monitor the execution state of the intelligent contract deployed in the blockchain network, and when the fact that the account number right is generated is monitored, the service server accesses any user node to obtain the right identification of the generated account number right.
In addition, the target user node may send the ticket identifier of the account ticket to the service server after generating the account ticket.
S112: and the service server establishes a service account and establishes a corresponding relation between the service account and the ticket identification.
After the service server obtains the ticket identification, a new service account can be registered, and the corresponding relation between the service account and the ticket identification is established. In this way, it is equivalent to that the target blockchain account has ownership of the service account number, and since the release of the correspondence between the target blockchain account and the ticket identifier must be performed by authorization of the target user and consensus of the blockchain network, the service account number of the target user is not easy to lose and is not easy to be stolen.
In addition, the service account registration method shown in fig. 1 may be used for more than one service server to register a service account. In the embodiment of the disclosure, for each user node, more than one intelligent contract for executing the account number ticket related logic is deployed on the user node; the contract identifications of more than one intelligent contract deployed on the user node correspond to more than one server identification one to one.
Thus, in step S100, the target user node receives an account registration instruction including the target server identifier. In step S102, the target user node determines, according to a target server identifier included in the account registration instruction, a contract identifier corresponding to the target server identifier as a target contract identifier, and then includes an account identifier of a target block chain account corresponding to the target user node and an account registration message of the target contract identifier. In step S106, each user node generates an account number ticket based on the intelligent contract corresponding to the target contract identifier, and establishes a corresponding relationship between the account number ticket and the account identifier. In step S110, when it is monitored that the intelligent contract corresponding to the target contract identifier generates the account ticket, the service server corresponding to the target server identifier obtains the ticket identifier from the blockchain network.
Fig. 2 is a schematic flowchart of a service account registration method based on a block chain according to an embodiment of the present disclosure.
In the service account registration method shown in fig. 2, actually, a user has a service account registered on a service server, and needs to generate an account ticket corresponding to the service account in a blockchain network, and allocate the generated account ticket to its own blockchain account. That is, the user needs to register its ownership of the registered service account in the blockchain.
The service account registration method shown in fig. 2 is based on the same inventive concept as the service account registration method shown in fig. 1, and when the method shown in fig. 2 is described later, reference may be made to the foregoing for relevant details, which are not described again.
The service account rating method shown in fig. 2 includes the following steps:
s200: and the target user node receives an account registration instruction.
In step S200, the target user node may be any user node in the blockchain network. The account registration instruction may be issued by a target user represented by the target user node. The intention of the account registration instruction is to instruct the blockchain network to generate an account ticket, and distribute the generated account ticket to a blockchain account of the target user, so that a service server under the chain can complete the binding of the account ticket and the registered service account of the target user.
It should be noted that the account registration instruction includes a service account. The business account is the business account to be registered and specified by the target user.
S202: and the target user node constructs an account registration message according to the account registration instruction, and signs the account registration message through a target block chain account corresponding to the target user node.
S204: the target user node broadcasts the account registration message to the blockchain network.
S206: and aiming at each user node obtaining the account registration message, after determining that the account registration message passes signature verification, the user node generates an account ticket based on a deployed intelligent contract and establishes a corresponding relation between a ticket identifier of the account ticket and the account identifier.
In step S202, the account registration message may include an account identifier of a target blockchain account corresponding to the target user node. Likewise, the target node needs to sign the account registration message through the target blockchain account. In step S206, each user node also needs to perform signature verification on the account registration message first, and after the verification is passed, an account ticket is generated based on the deployed intelligent contract, and a correspondence relationship between a ticket identifier of the account ticket and the account identifier is established.
S208: the user node issues the account registration message to a blockchain.
S210: and the target user node sends the ticket identification and the service account to a service server.
S212: and the business server establishes a corresponding relation between the business account and the ticket identification.
In addition, the service account registration method shown in fig. 1 may be used to register a service account for more than one service server. In the embodiment of the disclosure, for each user node, more than one intelligent contract for executing the account number ticket related logic is deployed on the user node; the contract identifications of more than one intelligent contract deployed on the user node correspond to more than one server identification one to one.
In step S200, the account registration instruction includes a target server identifier and a service account registered on a service server corresponding to the target server identifier. In step S202, the target user node determines, according to a target server identifier included in the account registration instruction, a contract identifier corresponding to the target server identifier as a target contract identifier, and then constructs an account registration message. The account registration message includes an account identifier of a target block chain account corresponding to the target user node and the target contract identifier. In step S206, each user node generates an account ticket based on the intelligent contract corresponding to the target contract identifier, and establishes a correspondence between a ticket identifier of the account ticket and the account identifier. In step S210, the target user node sends the ticket identifier and the service account to a service server corresponding to the target server identifier.
Based on the service account registration method shown in fig. 1 or the service account registration method shown in fig. 2, each service account registered on the service server may be mapped to an account ticket in the blockchain network, and ownership of each account ticket in the blockchain network is explicit and non-falsifiable.
Fig. 3 is a schematic flowchart of a service account login method based on a block chain according to an embodiment of the present disclosure.
In practice, through the method shown in fig. 1 or fig. 2, the service account is already mapped to the account ticket in the blockchain network, and then the user can log in the service account on the service server through the own blockchain account. Due to the high security of the blockchain account, the mode of logging in the business account is also very secure. For the service server, if a user logs in a service account through a blockchain account, the user can be considered as the actual owner of the service account.
The service account rating method shown in fig. 3 includes the following steps:
s300: and the target user node receives an account login instruction.
In step S300, the account login instruction may be issued by a target user represented by a target user node.
Further, if there is more than one service server, the account login command may contain a target server identification indicating which service server the target user wants to login to.
S302: and the target user node constructs an account login request according to the account login instruction, and signs the account login request through a target block chain account corresponding to the target user node.
In step S302, the target user node needs to sign the account login request through the target blockchain account to indicate that the account login request is authorized by the target blockchain account. And the account login instruction comprises an account identifier of the target block chain account.
S304: and the target user node sends the account login request to a service server.
In step S304, if the account login instruction includes a target server identifier, the target user node sends the account login request to a service server corresponding to the target server identifier.
S306: and after determining that the account login request passes the signature verification, the service server inquires a ticket identifier corresponding to the account identifier from the blockchain network according to the account login request.
In step S306, if the service server determines that the account login request passes the signature verification, it indicates that the account login request is authorized by the target blockchain account, which is equivalent to completing the user identity verification required for logging in the service account.
Next, the service server queries the blockchain network for a ticket identification corresponding to the account identification of the target blockchain account.
Further, if there is more than one ticket id queried, the service server may request the target user to select a ticket id.
S308: and the business server determines the business account corresponding to the inquired ticket identification and logs in the business account.
In step S308, the service server may determine the service account corresponding to the queried ticket identity according to the queried ticket identity and the pre-established correspondence between the ticket identity and the service account, which is the service account that the target user wants to log in.
Fig. 4 is a schematic flow chart of a service account selling method based on a block chain according to an embodiment of the present disclosure.
In practice, through the method shown in fig. 1 or fig. 2, the service account number is already mapped to the account number ticket in the blockchain network, and then the user can perform the transaction of the account number ticket through the own blockchain account. For the service server, usually, only the corresponding relationship between the ticket identification and the service account is maintained, and the personal information of the owner of the service account is not recorded, so that the users trade the own account ticket through a block chain network, and the business account trading under the chain is indirectly realized.
In a blockchain network, transactions between user nodes are generally authorized by a blockchain account of a transaction initiating node, and are issued to the blockchain after being authenticated by a consensus of each user node. This determines that valid transactions between user nodes are not revocable and therefore, changes in ownership of account credentials that occur through transactions between user nodes are also not revocable. This provides a safe and reliable business account transaction channel for users.
The service account selling method shown in fig. 4 includes the following steps:
s400: the selling user node receives an account selling instruction.
The selling user node is a user node controlled by a selling user who wants to sell the business account of the selling user node. It should be noted that, the selling user generally needs to provide the own private key with the blockchain program installed on the selling user node to log in the own blockchain account (for descriptive convenience, it is referred to as a selling blockchain account), and also obtains control over the selling user node.
The account number selling instruction can be issued by a selling user, and the intention of the selling user is to instruct the selling user node to sell an account right owned by the selling block chain account. In the business account selling method shown in fig. 4, an intelligent contract for executing logic related to account transaction is deployed on each user node. The details of the logic related to account transaction are described later. The method and apparatus shown in FIG. 4 is described below
The intelligent contract referred to in the description of the method shown in fig. 5 refers to an intelligent contract for executing logic associated with an account transaction.
The account sales instructions typically include a specified ticket identification and a sales amount. The account number ticket corresponding to the designated ticket identification is an account number ticket corresponding to a selling account identification, and the selling account identification is an account identification of a selling user account corresponding to the selling user node.
S402: and the selling user node constructs an account selling message according to the account selling instruction, and signs the account selling message through the selling block chain account.
The account number sale message comprises the sale account identification, the designated ticket identification and the sale amount. In step S402, the selling user node needs to sign the account number selling message through the selling blockchain account to indicate that the account number selling message is authorized through the selling blockchain account.
S404: the selling user node broadcasts the account selling message to a blockchain network.
S406: and for each user node obtaining the account selling message, after determining that the account selling message passes signature verification, the user node establishes a corresponding relation among the specified ticket identification, the selling amount and the contract identification of the intelligent contract based on the deployed intelligent contract.
In step S406, each user node determines that the account selling message is authorized by the owner identified by the designated ticket after determining that the account selling message passes signature verification.
Each user node may then establish a correspondence between the specified ticket identification, the sales amount, and the contract identification of the intelligent contract based on the deployed intelligent contract. This amounts to temporarily transferring account number credentials owned by the selling blockchain account to the smart contract custody, which in effect acts as a transaction intermediary. In a service account purchasing method to be mentioned later, it will be seen how a purchasing user purchases a service account from the smart contract.
S408: the user node issues the account selling message to a blockchain.
Meanwhile, each user node also needs to issue an account selling message passing signature verification to a block chain, and record and disclose the account selling behavior of the selling user.
In addition, in the service account selling method shown in fig. 4, after the account right corresponding to the specified right identifier is temporarily transferred to the smart contract, the selling user may cancel the selling at any time before the account right corresponding to the specified right identifier is not finally sold by the smart contract.
In particular, the selling user node may receive a revocation selling instruction, the revocation selling instruction including the designated ticket identification; then according to the revocation selling instruction, a revocation selling message is constructed, and the revocation selling message is signed through a selling block chain account corresponding to the selling user node, wherein the account selling message comprises a selling account identifier of the selling block chain account and the appointed ticket identifier; the sell revocation message is then broadcast to the blockchain network. In this way, for each user node that obtains the revocation sale message, after determining that the revocation sale message passes signature verification, the user node releases the correspondence among the designated ticket identification, the sale amount, and the contract identification of the smart contract based on the deployed smart contract, and issues the revocation sale message to a block chain.
Fig. 5 is a schematic flowchart of a service account purchasing method based on a block chain according to an embodiment of the present disclosure, including the following steps:
s500: the purchasing user node receives an account purchasing instruction.
The purchasing user node is a user node controlled by a purchasing user who wants to purchase a business account. It should be noted that, the purchasing user usually needs to provide its private key with the blockchain program installed on the purchasing user node to log in its blockchain account (for descriptive convenience, it is referred to as purchasing blockchain account), and also obtains control over the purchasing user node.
The account purchasing instruction can be issued by a purchasing user, and the intention of the purchasing user is to instruct the purchasing user node to purchase a desired business account. In the business account number purchasing method shown in fig. 5, an intelligent contract for executing logic related to account number transaction is deployed on each user node.
The account purchase instruction typically contains a specified ticket identification. And the designated ticket identifies the corresponding account ticket.
S502: and the purchasing user node constructs an account purchasing message according to the account purchasing instruction and signs the account purchasing message through a purchasing block chain account corresponding to the purchasing user node.
The account purchase message includes a purchase account identification and the designated ticket identification for the purchase blockchain account. In step S502, the purchasing user node needs to sign the account purchase message with the purchasing blockchain account to indicate that the account purchase message is authorized by the purchasing blockchain account.
S504: the purchasing user node broadcasts the account purchasing message to the blockchain network.
S506: and for each user node obtaining the account number purchasing information, after determining that the account number purchasing information passes signature verification, the user node deducts the selling amount corresponding to the appointed ticket identification from the purchasing block chain account based on the intelligent contract, and adds the selling amount to the selling block chain account of the selling account identification corresponding to the appointed ticket identification.
In step S406, after determining that the account purchase message passes signature verification, each user node determines that the account purchase message passes authorization of an owner of the purchase blockchain account corresponding to the purchase account identifier.
S508: the user node removes the corresponding relation among the appointed ticket identification, the selling amount and the contract identification, removes the corresponding relation between the appointed ticket identification and the selling account identification and establishes the corresponding relation between the appointed ticket identification and the purchasing account identification based on the deployed intelligent contract.
Each user node may then settle the transaction amount based on the deployed smart contract, based on the smart contract, and alter ownership of the account number ticket corresponding to the designated ticket identification. This corresponds to selling an account number ticket corresponding to the designated ticket id temporarily held by the smart contract to the purchasing blockchain account.
S510: the user node issues the account purchase message to a blockchain.
Meanwhile, each user node also needs to issue an account purchasing message passing signature verification to a block chain, and record and disclose account purchasing behaviors of the purchasing user.
In addition, in practical applications, each user node in the blockchain network may also perform service account transfer (generally, free).
Fig. 6 is a schematic flow chart of a service account number transfer method based on a block chain according to an embodiment of the present disclosure, which includes the following steps:
s600: and giving a user node to receive an account number transfer instruction.
The giving-out user node is a user node controlled by a giving-out user who wants to give the business account of the user node to others. Of course, the giving user should first take control of the giving user node.
The receiving account number transfer instruction is generally sent by the giving-out user, and the intention is to instruct the giving-out user node to transfer all account number tickets of the corresponding giving-out blockchain account to other blockchain accounts.
S602: and the giving-out user node constructs an account number transfer message according to the account number transfer instruction, and signs the account number transfer message through a giving-out block chain account corresponding to the giving-out user node.
S604: and the giving-out user node broadcasts the account number transfer message to the blockchain network.
S606: and for each user node which obtains the account number transfer message, after determining that the account number transfer message passes signature verification, the user node relieves the corresponding relation between the designated ticket identification and the giving-up account identification based on a deployed intelligent contract, and establishes the corresponding relation between the designated ticket identification and the given-up account identification.
In the business account number transfer method shown in fig. 6, transfer transactions are actually performed between two user nodes, and intelligent contracts do not need to be invoked.
Specifically, the giving user node constructs an account number transfer message and signs and authorizes through the giving block chain account. The account number transfer message comprises a giving-up account identifier, the designated ticket identifier and the transferee account identifier of the giving-up blockchain account.
And then, the user node broadcasts the account number transfer message after signature authorization to the block chain network, so that each user node which obtains the account number transfer message firstly carries out signature verification on the account number transfer message, and after the verification is passed, the ownership of the account number ticket corresponding to the appointed ticket identification is changed.
S608: and the user node issues the account number transfer message to a block chain.
Meanwhile, each user node issues the account number transfer message to a blockchain for showing so as to ensure that the ownership change of the account number ticket corresponding to the specified ticket identification cannot be revoked.
Through the service account management method based on the block chain shown in fig. 1 to fig. 6, the following beneficial effects can be achieved:
1. the method comprises the steps of mapping a service account number of a user into an account number ticket in a block chain account of the user, issuing the generated account number ticket and the attribution to a block chain after passing consensus verification by user nodes of the whole network, wherein the generation and the attribution of the account number ticket cannot be tampered, and the method is equivalent to the method that each user node in the block chain network carries out endorsement on the ownership of the service account number of the user, so that the service account number of the user cannot be lost.
2. The user can log in the service account number through the account number ticket in the own block chain account. Since the user's blockchain account is difficult to be hacked (the blockchain account is only controlled by the user's private key, which is very complicated and difficult to be hacked), the user's business account is also difficult to be hacked.
3. The transaction and transfer of account number tickets can be carried out between the blockchain accounts, which is equivalent to the transaction and transfer of business account numbers. Because the change of the account number ticket in any blockchain account needs to be issued to the blockchain for public notice after passing the consensus verification of each user node, and the change record of the account number ticket cannot be tampered, the change record is equivalent to a safe channel for transaction and transfer of business account numbers.
In addition, when the service account is a game account and the service server is a game server, after understanding the core idea of the present disclosure, a person skilled in the art can easily perform a right to a property in one game account, and map the right to a property right in a block chain, which is equivalent to registering the ownership of the property in the game account by the user in the block chain. Therefore, in the block chain, one block chain account not only can own a plurality of account number tickets, but also further owns a plurality of property tickets under each account number ticket. Therefore, the user can realize the transaction and transfer of the property right through the block chain network, and the transaction and transfer of the property in the service account number are also indirectly realized.
