Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

It will be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

Some embodiments of the present application provide a blockchain-based account attribute processing method. The method sets a single transaction limit, single-day limit, notification threshold and other security attributes in a blockchain account. To ensure the security of the user's account, if the private key of the account is stolen, the single limit and single-day limit can reduce the risk of the account balance being transferred in full. The notification threshold attribute can notify the actual owner of the account when transferring a higher amount, improving the security of the account. The method also provides the user with the service of confirming the identity of the other party before the user transfers money, so as to avoid losses caused by transferring the wrong object. The method can also set up a backup account corresponding to the account. When the private key is stolen, the user can freeze the account to avoid loss of account balance, and can transfer all the balance in the stolen account to the backup account to improve the security of the user's property. .

When the user needs to transfer money from the user account to other accounts, the user enters the transfer amount and the destination account address in the transfer interface displayed on the terminal. After the terminal detects that the user has entered the address of the destination account, it performs the identity confirmation of the owner of the destination account through the operations of the following steps S1-S3, including:

Step S1: Receive an identity confirmation request sent by the terminal, where the identity confirmation request includes a destination account address.

When the terminal detects that the user has entered the destination account address in the transfer interface, the terminal sends an identity confirmation request to the blockchain node, and the identity confirmation request includes the destination account address entered by the user. The blockchain node receives the identity confirmation request.

Step S2: Obtain the user identity information corresponding to the destination account address.

After receiving the identity confirmation request sent by the terminal, the blockchain node obtains the user identity information of the owner of the destination account from the account information of the destination account corresponding to the destination account address according to the destination account address included in the identity confirmation request, The user identity information may be the name or nickname of the owner of the purpose account.

Step S3: Send the user identity information to the terminal.

The blockchain node sends the obtained user identity information to the terminal. After acquiring the user identity information, the terminal displays the user identity information to the user. The user further confirms whether the owner of the currently input destination account address is the person who wants to transfer money through the user identity information displayed on the terminal. If not, the user can re-enter the destination account address corresponding to the person who wants to transfer money. After the user confirms that the currently entered destination account address is the destination account address corresponding to the person he wants to transfer, the user can trigger the transfer operation by clicking the Confirm Transfer button in the transfer interface.

Through the above method, before sending a transaction request, the identity of the owner corresponding to the destination account address is confirmed, which can avoid the situation of the wrong person being transferred due to the wrong input of the destination account address, and avoid the property loss caused by the wrong person for the user.

When the terminal detects that the confirm transfer button in the transfer interface is clicked by the user, the terminal obtains the transfer amount and destination account address entered by the user from the transfer interface, as well as the private key submitted by the user, and the pre-stored public key locally. The transfer amount and destination account address are signed by the user's private key, and the ciphertext of the transfer information is obtained. Then, a transaction request is generated according to the pre-stored public key and the generated ciphertext of the transfer information. The terminal sends the transaction request to the blockchain node. Then, as shown in Figure 1, based on the security attributes of the account, the blockchain node performs secure transaction processing on the transaction request of the account through the operations of the following steps S101-S103, including:

Step S101: Receive a transaction request of a user account sent by a terminal.

The blockchain node receives the transaction request of the user account sent by the terminal, and obtains the public key and the ciphertext of the transfer information from the transaction request. The ciphertext of the transfer information is decrypted by the public key to obtain the transfer information, and the transfer information includes the transfer amount and the destination account address. Since the public key is generated according to the user account address through a preset asymmetric encryption algorithm, the blockchain node can also perform a reverse operation on the public key through the preset asymmetric encryption algorithm to obtain the user account address. The preset asymmetric encryption algorithm can be RSA (RSA algorithm), DSA (Digital Signature Algorithm, digital signature algorithm), ECC (Elliptic curve cryptography, elliptic encryption algorithm), etc.

After obtaining the transfer amount, destination account address and user account address corresponding to the current transaction request in the above manner, the transaction request is processed securely through the operations of the following steps S102 and S103.

Step S102: Determine whether the transaction request conforms to the security rule corresponding to the security attribute of the user account.

In this embodiment of the present application, the security attributes include one or more of a single transaction quota attribute, a single daily quota attribute, and a notification threshold attribute.

Step S103: If it is determined that the transaction request does not conform to the security rule corresponding to the security attribute, send a security prompt notification to the terminal according to the security rule and the transaction request, and the security prompt notification is used to prompt the user that the transaction request does not conform to the security rule.

In the embodiment of the present application, the security attributes set in the blockchain account may include a single limit attribute, and the security rule corresponding to the single limit attribute may be that the transfer operation is performed only when the transfer amount is less than or equal to the specified single limit. Specifically, the corresponding security operations are performed based on the single limit attribute through the operations of the following steps A1 and A2, including:

Step A1: Determine whether the transfer amount included in the transaction request is greater than the single limit specified by the security rule corresponding to the single limit attribute; if so, determine that the transaction request does not conform to the security rule corresponding to the single limit attribute.

The blockchain node compares the transfer amount included in the transaction request with the single limit specified by the security rule corresponding to the single limit attribute. If the transfer amount is greater than the single limit, it is determined that the transaction request does not conform to the security rule corresponding to the single limit attribute. , and then perform step A2. If the transfer amount is less than or equal to the single limit, it is determined that the transaction request complies with the security rules corresponding to the single limit attribute.

Step A2: According to the security rules and the transaction request, a first transaction failure notification is generated, and the first transaction failure notification is used to prompt that the transfer amount exceeds a single limit; the first transaction failure notification is sent to the terminal.

When the transaction request does not conform to the security rules corresponding to the single limit attribute, the blockchain node sends the first transaction failure notification to the terminal. The first transaction failure notification includes the transfer amount and the single limit, which is used to prompt that the transfer amount is greater than the single transaction limit.

If it is determined in step A1 that the transfer amount is less than or equal to the single limit, normal transfer processing can be performed on the transaction request. Specifically, according to the transfer amount and the user account address, the transfer amount is subtracted from the current balance of the user account. And according to the transfer amount and the destination account address, add the transfer amount to the current balance of the destination account.

After transferring money from the user account to the destination account through the above method, a successful transfer notification is generated according to the user account address, the transfer amount and the destination account address. Success message. Send a successful transfer notification to the terminal, so that the user can know the balance change of the user's account in real time.

After the transfer is completed in the above manner, a transfer record is also generated according to the transfer amount, destination account address, user account address, timestamp, etc. The correspondence between user account addresses and transfer records is stored in each blockchain node. Based on the traceability and non-tampering characteristics of the blockchain, the transfer records of the user accounts are stored in the blockchain nodes, which can ensure the authenticity of the transfer records of the user accounts and avoid account book fraud.

In other embodiments of the present application, a single-day limit attribute is also set in the blockchain account, and the security rule corresponding to the single-day limit attribute may be that the total amount of transfers in a single day must be less than or equal to the specified single-day limit. Specifically, the following steps A3-A6 are used to perform corresponding security operations based on the single-day limit attribute, including:

Step A3: Obtain the total transfer amount of the day corresponding to the user account.

For each blockchain account, the blockchain node will record the total amount of transfers on the day corresponding to the account in the account information. According to the public key included in the transaction request, the blockchain node performs reverse operation through a preset asymmetric encryption algorithm to obtain the user account address corresponding to the user account. According to the user's account address, obtain the total transfer amount of the user's account on the day from the corresponding account information.

Step A4: Calculate the sum of the total transfer amount on the day and the transfer amount included in the transaction request.

Step A5: Determine whether the sum value is greater than the single-day limit specified by the security rule corresponding to the single-day limit attribute; if so, determine that the transaction request does not conform to the security rule corresponding to the single-day limit attribute.

The blockchain node compares the above calculated sum with the single-day limit specified by the security rule corresponding to the single-day limit attribute. If the sum is greater than the single-day limit, it is determined that the transaction request does not conform to the security rule corresponding to the single-day limit attribute. , and then perform step A6. If the sum value is less than or equal to the single-day limit, it is determined that the transaction request complies with the security rules corresponding to the single-day limit attribute.

Step A6: According to the security rules and the transaction request, a second transaction failure notification is generated, and the second transaction failure notification is used to prompt the transaction request that the total transfer amount on the day will exceed the single-day limit; send the second transaction failure notification to the terminal.

When the transaction request does not conform to the security rules corresponding to the single-day limit attribute, the blockchain node sends a second transaction failure notification to the terminal, and the second transaction failure notification includes the transfer amount and the single-day limit, which is used to remind that the transaction request will make the same day. The total amount of the transfer exceeds the daily limit.

If it is determined in step A5 that the calculated sum is less than or equal to the single-day limit, normal transfer processing can be performed on the transaction request. The specific transfer process is the same as the transfer process described above, and will not be repeated here. After the transfer is completed, a notification of successful transfer is sent to the terminal through the relevant operations above, and the correspondence between the user account address and the transaction record corresponding to this transaction is stored in the blockchain node.

In some embodiments of the present application, the above single limit attribute and single day limit attribute can be set in the blockchain node at the same time, and when it is determined through step A1 that the transfer amount included in the transaction request is less than or equal to the single limit, further Determine whether the transfer amount will exceed the single-day limit by the operation of steps A3-A5, and if so, discard the transaction request, and send a second transaction failure notification to the terminal through the operation of step A6. If not, transfer the transaction request.

In some embodiments of the present application, a notification threshold attribute is also set in the blockchain account, and the security rule corresponding to the notification threshold attribute is when the transfer amount is less than the single limit and greater than the preset amount specified by the security rule corresponding to the notification threshold attribute Notify the user of the transfer amount. And specifically through the operations of the following steps A7-A9 to perform corresponding security operations based on the notification threshold attribute, including:

Step A7: Determine whether the transfer amount included in the transaction request is less than the single limit and greater than the preset amount specified by the security rule corresponding to the notification threshold attribute; if so, it is determined that the transaction request does not conform to the security rule corresponding to the notification threshold attribute.

In step A1, if it is determined that the transfer amount is less than the single limit, the transfer amount is further compared with the preset amount specified in the security rule corresponding to the notification threshold attribute, and if the transfer amount is greater than the preset amount, it is determined that the transaction request does not meet the requirements The security rule corresponding to the threshold attribute is notified, and step A8 is subsequently performed. If the transfer amount is less than or equal to the preset amount, it is determined that the transaction request complies with the security rule corresponding to the notification threshold attribute.

Step A8: Obtain the user address corresponding to the user account according to the transaction request.

According to the public key included in the transaction request, the reverse operation is performed through a preset asymmetric encryption algorithm to obtain the user account address corresponding to the user account. The user address is obtained from the account information of the user account corresponding to the user account address, where the user address is the client URL of the actual owner of the user account.

Step A9: According to the security rules and the transaction request, a large-value transaction notification is generated, and the large-value transaction notification is used to prompt the owner of the user account that the transfer amount of the transaction request is greater than the preset amount; send the large-value transaction notification to the corresponding user address. user terminal.

Send a large-value transaction notification to the user terminal corresponding to the user address, where the large-value transaction notification includes the transfer amount, which is used to prompt the actual owner of the user account that the transfer amount requested by the transaction is greater than the preset amount.

The notification threshold attribute is set in the user account. If the transfer amount in the user's transaction request is greater than the preset amount specified by the notification threshold attribute, the actual owner of the user account will be notified that the transfer amount is greater than the preset amount, so that the user account is blocked. During theft, the actual owner of the user account can be prevented from being informed of the large-amount transfer in his user account in time, which can reduce the loss of the user account.

When it is determined that the transfer amount is less than the single limit and greater than the preset amount corresponding to the notification threshold attribute, and it is determined that the transfer amount is less than or equal to the preset amount corresponding to the notification threshold attribute, the transaction request is processed by transfer.

In the embodiment of the present application, if the user believes that his account has been stolen, the user's account can be frozen through the operations of the following steps A10-A12, which specifically include:

Step A10: The receiving terminal sends an account freezing request of the user account.

When the user needs to freeze the user account, the account freezing request is sent to the blockchain node through the terminal, and the account freezing request includes the user account address. The blockchain node receives the account freezing request, and within the preset freezing time period starting from receiving the account freezing request, any transaction request for the received user account corresponding to the user account address, except for the operation of transferring money to the standby account , the blockchain nodes discard these transaction requests and do not respond.

Step A11: Within the preset freezing period, if a transaction request corresponding to the user account is received.

Step A12: Determine whether the destination account address included in the transaction request is an alternate account address of the user account; if so, perform transfer processing on the transaction request; if not, discard the transaction request.

Within the preset freezing period of the user account, if a transaction request corresponding to the user account is received, first obtain the destination account address included in the transaction request, and then obtain the backup account corresponding to the user account from the account information of the user account address, compare whether the destination account address of the transaction request is consistent with the alternate account address, if so, perform transfer processing on the transaction request, if not, discard the transaction request.

In the embodiment of the present application, the above-mentioned single limit attribute, single-day limit attribute, notification threshold attribute, etc. may not be set in the backup account, so that the user can transfer the account balance from the backup account to his own account with high security in time.

The user account may also be frozen repeatedly within the preset freezing period of the above-mentioned user account, and each time an account freezing request of the user account is received again, the freezing period of the user account is extended by the preset freezing period.

Set the freezing attribute for the user account. When receiving the freezing request of the user account, the user account will be frozen for a preset freezing period. During the preset freezing period, any transaction request except the transfer to the standby account of the user account will be blocked. throw away. In this way, when the user learns that his user account has been stolen, he can avoid losses by freezing the account. Freeze the user account multiple times, and each time the user is requested to freeze, the user account freezing time will be extended by the preset freezing time period, so as to maximize the protection of the user account.

The security attributes and their corresponding security rules are set in the blockchain account. When receiving a transaction request from the account, first determine whether the transaction request conforms to the security rules corresponding to the security attributes, and if so, execute the security rules corresponding to the security rules. operate. In this way, the security of the user account is improved through the security attributes and the corresponding security rules.

If the private key of the account is stolen, the single limit and single day limit can reduce the risk of the account balance being transferred in full. The nickname confirmation attribute can enable the user to confirm the identity of the other party before the user transfers, so as to avoid losses caused by the wrong object. The notification threshold can notify the user when a higher amount of transfer is made, improving the security of the account. Freezing and standby accounts can freeze accounts when the private key is stolen to avoid loss of account balances, and can transfer all the balances in the stolen accounts to the standby accounts to improve the security of user property.
