Some embodiments of the present application provide an account attribute processing method based on a blockchain, where multiple security attributes such as a single limit, a single daily limit, and a notification threshold are set in a blockchain account, and the security of a user account is ensured through the security attributes, and if a private key of the account is stolen, the risk that the balance of the account is completely transferred can be reduced by the single limit and the single daily limit. The notify threshold attribute may notify the actual owner of the account when transferring higher amounts, improving the security of the account. The method also provides the service for the user to confirm the identity of the other party before the user transfers the account, and avoids the loss caused by transferring the wrong object. The method can also set a spare account corresponding to the account, so that the user can freeze the account when the private key is stolen, the balance loss of the account is avoided, the balance in the stolen account can be completely transferred to the spare account, and the property safety of the user is improved.
When the user needs to transfer money from the user account to other accounts, the user inputs the transfer amount and the destination account address in a transfer interface displayed by the terminal. After detecting that the user inputs the destination account address, the terminal performs identity confirmation on the owner of the destination account through the following operations of steps S1-S3, which specifically includes:
step S1: and receiving an identity confirmation request sent by the terminal, wherein the identity confirmation request comprises a destination account address.
When the terminal detects that a user inputs a destination account address in a transfer interface, the terminal sends an identity confirmation request to the blockchain node, wherein the identity confirmation request comprises the destination account address input by the user. The blockchain node receives the identity confirmation request.
Step S2: and acquiring user identity information corresponding to the destination account address.
After receiving an identity confirmation request sent by a terminal, a block link node acquires user identity information of an owner of a target account from account information of the target account corresponding to a target account address according to the target account address included in the identity confirmation request, wherein the user identity information can be the name or nickname of the owner of the target account.
Step S3: and sending the user identity information to the terminal.
And the block link point sends the acquired user identity information to the terminal. And after the terminal acquires the user identity information, displaying 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 or not through the user identity information displayed by the terminal, and if not, the user can input the destination account address corresponding to the person who wants to transfer money again. And after the user confirms that the currently input destination account address is the destination account address corresponding to the person who wants to transfer accounts, the transfer operation is triggered by clicking a confirmation transfer button in the transfer interface.
By the method, before the transaction request is sent, the owner corresponding to the destination account address is firstly identified, so that the condition of transferring a wrong person due to the mistake input of the destination account address can be avoided, and property loss caused to the user due to the wrong person is avoided.
When the terminal detects that a confirmation transfer button in a transfer interface is clicked by a user, the terminal obtains a transfer amount and a destination account address input by the user from the transfer interface, obtains a private key submitted by the user, and locally obtains a pre-stored public key. And signing the transfer amount and the destination account address through a private key of the user to obtain a transfer information ciphertext. And then generating a transaction request according to the pre-stored public key and the generated transfer information ciphertext. The terminal sends the transaction request to the block link point. Then, as shown in fig. 1, the block link points perform secure transaction processing on the transaction request of the account through the following operations of steps S101 to S103 based on the security attributes of the account, including:
step S101: and receiving a transaction request of the user account sent by the terminal.
And the block chain node receives a transaction request of the user account sent by the terminal, and acquires a public key and a transfer information ciphertext from the transaction request. And decrypting the transfer information ciphertext through the public key to obtain transfer information, wherein the transfer information comprises the transfer amount and the destination account address. The public key is generated by operation through the preset asymmetric encryption algorithm according to the user account address, so that the block link point can also perform reverse operation on the public key through the preset asymmetric encryption algorithm to obtain the user account address. The predetermined asymmetric encryption Algorithm may be rsa (rsa Algorithm), DSA (Digital Signature Algorithm), ECC (Elliptic encryption Algorithm), etc.
After the transfer amount, the destination account address and the user account address corresponding to the current transaction request are obtained in the above manner, the transaction request is subjected to secure transaction processing through the following operations of steps S102 and S103.
Step S102: and judging whether the transaction request conforms to a safety rule corresponding to the safety attribute of the user account.
In the embodiment of the application, the security attribute comprises one or more of a single limit attribute, a single-day limit attribute and a notification threshold attribute.
Step S103: and if the transaction request is determined not to be in accordance with the safety rule corresponding to the safety attribute, sending a safety prompt notice to the terminal according to the safety rule and the transaction request, wherein the safety prompt notice is used for prompting the user that the transaction request is not in accordance with the safety rule.
In this embodiment of the application, the security attribute set in the blockchain account may include a single quota attribute, and the security rule corresponding to the single quota attribute may be that the transfer operation is performed only when the transfer amount is less than or equal to a specified single quota. Specifically, the following steps a1 and a2 are performed to perform corresponding security operations based on the single quota attribute, including:
step A1: judging whether the transfer amount included in the transaction request is larger than the single limit specified by the safety rule corresponding to the single limit attribute; if so, the transaction request is determined not to conform to the security rule corresponding to the single quota attribute.
And the block link point compares the transfer amount included in the transaction request with the single quota specified by the safety rule corresponding to the single quota attribute, if the transfer amount is greater than the single quota, the transaction request is determined not to conform to the safety rule corresponding to the single quota attribute, and the step A2 is executed subsequently. And if the transfer amount is less than or equal to the single limit, determining that the transaction request conforms to the safety rule corresponding to the single limit attribute.
Step A2: generating a first transaction failure notice according to the safety rule and the transaction request, wherein the first transaction failure notice is used for prompting that the transfer amount exceeds a single limit; and sending a first transaction failure notice to the terminal.
And when the transaction request does not accord with the safety rule corresponding to the single limit attribute, the block chain node sends a first transaction failure notice to the terminal, wherein the first transaction failure notice comprises the transfer amount and the single limit and is used for prompting that the transfer amount is larger than the single limit.
If the transfer amount is less than or equal to the single limit as determined in step A1, normal transfer processing may be performed on the transaction request. Specifically, the transfer amount is subtracted from the current balance of the user account according to the transfer amount and the user account address. And adding the transfer amount on the basis of the current balance of the destination account according to the transfer amount and the destination account address.
After the transfer is carried out from the user account to the destination account in the mode, a transfer success notice is generated according to the user account address, the transfer amount and the destination account address, and the transfer success notice comprises the user account address, the transfer amount, the destination account address and prompt information for prompting the transfer success. And sending a transfer success notice to the terminal so that the user can know the balance change condition of the user account in real time.
After the transfer is completed in the mode, a transfer record is generated according to the transfer amount, the destination account address, the user account address, the timestamp and the like. And storing the corresponding relation between the user account address and the transfer record in each block chain node. Based on the traceable and non-falsifiable characteristics of the block chain, the transfer records of the user accounts are stored in the block chain link points, the authenticity of the transfer records of the user accounts can be ensured, and account book counterfeiting is avoided.
In other embodiments of the present application, a single-day quota attribute is also set in the blockchain account, and the security rule corresponding to the single-day quota attribute may be that the total amount of the transfers on a single day is less than or equal to the specified single-day quota. Specifically, the following steps A3-a6 are performed to perform corresponding safety operations based on the single-day quota attribute, including:
step A3: and acquiring the total amount of the money transfer on the current day corresponding to the user account.
For each blockchain account, the blockchain node records the total daily transfer amount corresponding to the account in the account information. And the block chain node performs reverse operation through a preset asymmetric encryption algorithm according to the public key included in the transaction request to obtain a user account address corresponding to the user account. And acquiring the current day transfer sum of the user account from the corresponding account information according to the user account address.
Step A4: the sum of the total daily transfer amount and the transfer amount included in the transaction request is calculated.
Step A5: judging whether the sum is larger than the single-day quota specified by the safety rule corresponding to the single-day quota attribute; if so, determining that the transaction request does not conform to the safety rule corresponding to the single-day quota attribute.
And the block link point compares the calculated sum value with the single-day quota specified by the safety rule corresponding to the single-day quota attribute, if the sum value is greater than the single-day quota, the block link point determines that the transaction request does not conform to the safety rule corresponding to the single-day quota attribute, and then step A6 is executed. And if the sum is less than or equal to the single-day quota, determining that the transaction request conforms to the safety rule corresponding to the single-day quota attribute.
Step A6: generating a second transaction failure notice according to the safety rule and the transaction request, wherein the second transaction failure notice is used for prompting that the transaction request can enable the total amount of the daily transferred accounts to exceed the single-day limit; and sending a second transaction failure notice to the terminal.
And when the transaction request does not accord with the safety rule corresponding to the single-day quota attribute, the block chain node sends a second transaction failure notice to the terminal, wherein the second transaction failure notice comprises the transfer amount and the single-day quota and is used for prompting that the transaction request can enable the total daily transfer amount to exceed the single-day quota.
If step A5 determines that the calculated sum is less than or equal to the single daily limit, then normal transfer processing may be performed for the transaction request. The specific transfer processing procedure is the same as the transfer procedure described above, and is not described herein again. And after the transfer is finished, a transfer success notice is sent to the terminal through the related operation, and the corresponding relation between the user account address and the transaction record corresponding to the transaction is stored in the block link point.
In some embodiments of the present application, the single limit attribute and the single daily limit attribute may be set in the blockchain node, when it is determined that the transfer amount included in the transaction request is less than or equal to the single limit through step a1, it is further determined whether the transfer amount would cause the total daily transfer amount to exceed the single daily limit through the operations of steps A3-a5, and if so, the transaction request is discarded, and a second transaction failure notification is sent to the terminal through the operation of step a 6. If not, the transfer process is carried out on the transaction request.
In some embodiments of the application, a notification threshold attribute is further set in the blockchain account, and the transfer amount is notified to the user when the transfer amount is smaller than the single limit and larger than a preset amount specified by the security rule corresponding to the notification threshold attribute. And specifically, the following steps A7-A9 are used for carrying out corresponding safety operation based on the notification threshold attribute, including:
step A7: judging whether the transfer amount included in the transaction request is smaller than a single limit and larger than a preset amount specified by a safety rule corresponding to the notification threshold attribute; if so, the transaction request is determined not to conform to the security rule corresponding to the notification threshold attribute.
If the transfer amount is judged to be less than the single limit in the step A1, the transfer amount is further compared with the preset amount specified by the safety rule corresponding to the notification threshold attribute, if the transfer amount is greater than the preset amount, it is determined that the transaction request does not conform to the safety rule corresponding to the notification threshold attribute, and the step A8 is executed subsequently. And if the transfer amount is less than or equal to the preset amount, determining that the transaction request conforms to the safety rule corresponding to the notification threshold attribute.
Step A8: and acquiring a user address corresponding to the user account according to the transaction request.
And performing reverse operation through a preset asymmetric encryption algorithm according to the public key included in the transaction request to obtain a user account address corresponding to the user account. And acquiring a user address from the account information of the user account corresponding to the user account address, wherein the user address is a client URL of an actual owner of the user account.
Step A9: generating a large-amount transaction notification according to the security rule and the transaction request, wherein the large-amount transaction notification is used for prompting that the transfer amount of the owner of the user account in the transaction request is larger than a preset amount; and sending a large amount transaction notification to a user terminal corresponding to the user address.
And sending a large-amount transaction notification to a user terminal corresponding to the user address, wherein the large-amount transaction notification comprises a transfer amount and is used for prompting an actual owner of the user account that the transfer amount of the transaction request is larger than a preset amount.
The notification threshold attribute is set in the user account, if the transfer amount in the user transaction request is larger than the preset amount specified by the notification threshold attribute, the actual owner of the user account is notified of the fact that the transfer amount is larger than the preset amount, and therefore when the user account is stolen, the actual owner of the user account can be prevented from timely knowing that the user account has large-amount transfer, and loss of the user account can be reduced.
And under the conditions that the transfer amount is judged to be smaller than the single limit and larger than the preset amount corresponding to the notification threshold attribute, and the transfer amount is judged to be smaller than or equal to the preset amount corresponding to the notification threshold attribute, the transfer processing is carried out on the transaction request.
In the embodiment of the present application, if the user thinks that the account of the user is stolen, the freezing operation may be performed on the user account through the following operations of steps a10-a12, which specifically include:
step A10: and the receiving terminal sends an account freezing request of the user account.
When a user needs to freeze a user account, an account freezing request is sent to a blockchain node through a terminal, and the account freezing request comprises a user account address. And the block chain node receives the account freezing request, and discards the transaction requests for any transaction requests of the user account corresponding to the received user account address except for the operation of transferring to the standby account within the preset freezing duration after the account freezing request is received, and does not respond.
Step A11: and if a transaction request corresponding to the user account is received within the preset freezing duration.
Step A12: judging whether the destination account address included in the transaction request is a standby account address of the user account; if yes, transferring accounts to the transaction request; if not, the transaction request is discarded.
Within the preset freezing duration of the user account, if a transaction request corresponding to the user account is received, a destination account address included in the transaction request is firstly obtained, then a standby account address corresponding to the user account is obtained from account information of the user account, whether the destination account address of the transaction request is consistent with the standby account address or not is compared, if yes, transfer processing is carried out on the transaction request, and if not, the transaction request is discarded.
In the embodiment of the application, the single limit attribute, the single-day limit attribute, the notification threshold attribute and the like may not be set in the standby account, so that a user can transfer the account balance from the standby account to an account with high security in time.
And repeatedly freezing the user account within the preset freezing duration of the user account, and prolonging the freezing time of the user account by the preset freezing duration each time an account freezing request of the user account is received again.
Setting a freezing attribute for a user account, freezing the user account for a preset freezing time length when a freezing request of the user account is received, and discarding any transaction request except for transferring to a standby account of the user account within the preset freezing time length. Thus, under the condition that the user knows that the user account is stolen, the loss can be avoided by freezing the account. And freezing the user account for multiple times, and prolonging the freezing time of the user account for a preset freezing time length once the freezing is requested, so that the user account can be protected to the maximum extent.

The nickname confirmation attribute can enable the user to confirm the identity of the opposite party before the user transfers the account, and loss caused by transferring the wrong object is avoided. The notification threshold can notify the user when transferring higher amount of money, and the safety of the account is improved. The frozen and standby accounts can freeze the account when the private key is stolen, so that the balance loss of the account is avoided, and the balance in the stolen account can be completely transferred to the standby account, thereby improving the security of the property of the user.
According to the embodiment of the application, the safety attribute and the safety rule corresponding to the safety attribute are set in the blockchain account, when the transaction request of the account is received, whether the transaction request accords with the safety rule corresponding to the safety attribute is judged, and if yes, the safety operation corresponding to the safety rule is executed. Thus, 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 risk that the balance of the account is completely transferred can be reduced by the single limit and the single daily limit. The user identity confirmation of the destination account can ensure that the user confirms the identity of the other party before the user transfers the account, and the loss caused by transferring the wrong object is avoided. The notification threshold attribute can notify the user when a transfer of a higher amount is performed, improving the security of the account. The frozen and standby accounts can freeze the account when the private key is stolen, so that the balance loss of the account is avoided, and the balance in the stolen account can be completely transferred to the standby account, thereby improving the security of the property of the user.
