A detailed description is given below of a data processing method, an apparatus, a device, and a storage medium based on a block chain according to an embodiment of the present application.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a block chain-based data processing method provided in an embodiment of the present application, where the data processing method includes steps S101-S104; specifically, the method comprises the following steps:
s101, responding to a data protection request of the user terminal for target data, and configuring a locking parameter for protecting the target data for the target data.
S102, responding to the parameter query request of the user terminal for the locking parameter, and sending the parameter value of the locking parameter at the first time to the user terminal.
S103, receiving a data processing instruction of the user terminal aiming at the target data, and verifying parameter information carried in the data processing instruction according to a parameter value of the locking parameter at a first moment when the execution result of the data processing instruction is determined to depend on the data value of the target data.
And S104, responding to the fact that the parameter information carried in the data processing instruction passes verification, and executing the data processing instruction aiming at the target data to obtain a data processing result of the target data.
In the data processing method based on the block chain provided by the embodiment of the application, a data protection request of a user terminal for target data is responded, and a locking parameter for protecting the target data is configured for the target data; responding to a parameter query request of the user terminal for the locking parameter, and sending the parameter value of the locking parameter at the first moment to the user terminal; receiving a data processing instruction of a user terminal aiming at target data, and verifying parameter information carried in the data processing instruction according to a parameter value of a locking parameter at a first moment when the execution result of the data processing instruction is determined to depend on the data value of the target data; and responding that the parameter information carried in the data processing instruction passes verification, and executing the data processing instruction aiming at the target data to obtain an execution result of the data processing instruction.
By the method, the realization of the interface idempotent function can get rid of the dependency on specific data processing logic, and the user terminal can conveniently access the intelligent contract system.
In this embodiment of the application, the data processing method based on the block chain is applied to an intelligent contract system, where the intelligent contract system and at least one user terminal are located on the same block chain, and each user terminal can access the intelligent contract system on the block chain and store electronic information with storage value in the intelligent contract system. The embodiment of the present application does not limit any specific terminal type of each ue in the block chain.
The following takes a user equipment as an example, and respectively illustrates each step in the above data processing method based on a block chain according to the embodiment of the present application:
s101, responding to a data protection request of the user terminal for target data, and configuring a locking parameter for protecting the target data for the target data.
Here, each user terminal corresponds to an intelligent contract in the intelligent contract system, and the intelligent contract system may receive data to be stored sent by the user terminal and store the data to be stored in the intelligent contract corresponding to the user terminal.
The target data may be used to characterize all data stored by the user terminal in the intelligent contract system, and may also be used to characterize a part of data that needs to be protected and is specified by the user terminal from the stored data.
Specifically, the locking parameter is used for locking and protecting the target data, an initial parameter value of the locking parameter may be automatically generated by the intelligent contract system or may be set by the user terminal, and the embodiment of the present application is not limited to the initial parameter value of the locking parameter.
S102, responding to the parameter query request of the user terminal for the locking parameter, and sending the parameter value of the locking parameter at the first time to the user terminal.
It should be noted that the user terminal may directly communicate with the intelligent contract system by accessing an external interface of the intelligent contract system, or may send a function name of the intelligent contract to be called to the commission system, and indirectly access the intelligent contract in the intelligent contract system through the commission system.
Specifically, when the user terminal is in direct communication with the intelligent contract system, the user terminal may directly send the parameter query request to an external interface of the intelligent contract system, the intelligent contract system responds to the parameter query request, obtains a parameter value of the locking parameter at the current time from the intelligent contract corresponding to the user terminal, and sends the parameter value of the locking parameter at the current time to the user terminal as the parameter value of the locking parameter at the first time.
Specifically, when the user terminal and the intelligent contract system indirectly communicate with each other through the commission system, the user terminal may send the parameter query request and the function name of the intelligent contract to be called to the commission system, and indirectly access the intelligent contract in the intelligent contract system through the commission system, and the intelligent contract system indirectly sends the parameter value of the locking parameter at the current time as the parameter value of the locking parameter at the first time to the user terminal through the commission system.
S103, receiving a data processing instruction of the user terminal aiming at the target data, and verifying parameter information carried in the data processing instruction according to a parameter value of the locking parameter at a first moment when the execution result of the data processing instruction is determined to depend on the data value of the target data.
Here, the user terminal needs to perform different data processing on the target data according to different service requirements (which is equivalent to sending different types of data processing instructions for the target data), and the embodiment of the present application is not limited in any way as to the specific data processing logic corresponding to the data processing instructions.
Illustratively, based on the data modification requirement, the user terminal may send a data modification instruction for modifying the target data to the intelligent contract system to instruct the intelligent contract system to modify the target data, so as to modify the target data into a data modification result specified in the data modification instruction; modifying requirements based on the data; based on the data increment/decrement demand, the user terminal can send a data increment/decrement instruction for performing addition and subtraction operation on the target data to the intelligent contract system so as to instruct the intelligent contract system to increase/decrease the data increment/data decrement specified in one data modification instruction on the basis of the target data.
Here, whether or not the execution result of the data processing instruction depends on the data value of the target data may be determined based on whether or not the execution result of the data processing instruction changes depending on the data value of the target data.
Specifically, for the case where the execution result of the data processing instruction does not depend on the data value of the target data, the following is exemplarily described:
for example, when the execution result of the data processing instruction is a fixed result (for example, the data processing instruction is that the target data is modified into data x), the execution result based on the data processing instruction does not change due to the difference of the data value of the target data, so that the execution result of the data processing instruction can be determined not to depend on the data value of the target data; for another example, when the data processing instruction does not involve performing arithmetic processing on the target data (for example, the data processing instruction is a data query instruction for performing data query on the target data), the execution result based on the data processing instruction does not change due to the difference of the data value of the target data, and thus it can be determined that the execution result of the data processing instruction does not depend on the data value of the target data.
It should be noted that, because the data query does not cause the data value of the target data to change at the adjacent time, the execution result of the data query instruction may also be considered to be the return of the target data, and is not related to the specific data value of the target data.
Specifically, for the case where the execution result of the data processing instruction depends on the data value of the target data, the following is exemplarily described:
for example, when the execution result of the data processing instruction is a non-fixed result and the execution result of the data processing instruction is affected by the target data (e.g. the data processing instruction is data update to the target data at fixed unit step length), the execution result based on the data processing instruction may change due to the difference of the data value of the target data, and thus it may be determined that the execution result of the data processing instruction does not depend on the data value of the target data; for another example, when the execution result of the data processing instruction involves changing from the target data to an operation result based on the target data (e.g., the data processing instruction is multiplying the target data by the data x), the execution result based on the data processing instruction may change according to the data value of the target data, and thus it may be determined that the execution result of the data processing instruction depends on the data value of the target data.
And S104, responding to the fact that the parameter information carried in the data processing instruction passes verification, and executing the data processing instruction aiming at the target data to obtain a data processing result of the target data.
Specifically, in step S102, the user terminal obtains a parameter value of the locking parameter at the first time from the intelligent contract system through the parameter query request (that is, a parameter value of the locking parameter at the current time when responding to the parameter query request), and in the subsequently sent data processing instruction, the user terminal may send the obtained parameter value of the locking parameter at the first time as parameter information to the intelligent contract system together with the data processing instruction, so that the intelligent contract system can verify the authenticity of the data processing instruction according to the parameter information carried in the data processing instruction.
When detecting that the parameter information carried in the data processing instruction is the same as the parameter value of the locking parameter at the first time, determining that the parameter information carried in the data processing instruction passes verification; at this time, the intelligent contract system executes the data processing instruction and sends the executed data processing result to the user terminal.
Here, when detecting that parameter information carried in a data processing instruction is different from a parameter value of a locking parameter at a first time, determining that verification of the parameter information carried in the data processing instruction fails; at this time, the intelligent contract system refuses to execute the data processing instruction, thereby ensuring.
The following detailed description is made for the specific implementation process of the above steps in the embodiments of the present application, respectively:
in the specific implementation process of step S103, considering that there may be a plurality of user terminals capable of communicating with the intelligent contract system on the block chain, at this time, after receiving a data processing instruction of the user terminal for the target data, the identity of the user terminal may be verified by the following method, so as to improve the data security performance of the target data.
As shown in fig. 2, fig. 2 is a schematic flowchart illustrating a method for authenticating an identity of a user terminal according to an embodiment of the present application, where in step S103, a data processing instruction further carries a block chain address of the user terminal and user signature information; at this time, after receiving a data processing instruction of the user terminal for the target data, the method includes steps S201 to S203; specifically, the method comprises the following steps:
s201, verifying the authenticity of the user signature information according to the block chain address of the user terminal.
Here, for the block chain address, it should be noted that: in the blockchain, when any user terminal accesses the blockchain, the identity on the blockchain is unique, and the unique identity is the blockchain address of the user terminal. Specifically, in the embodiment of the present application, the block chain address is equivalent to a corresponding unique identity address when the user terminal accesses the intelligent contract system on the block chain; that is, the blockchain address may uniquely identify each user terminal from among a plurality of user terminals included on the blockchain.
Specifically, the intelligent contract system stores the user signature of the user terminal, wherein the specific signature format of the user signature can be set by the user terminal, and the block chain address can uniquely identify the identity of the user terminal, so that the intelligent contract system can determine the unique user terminal from a plurality of user terminals according to the block chain address, and thereby the real user signature pre-stored in the intelligent contract system by the user terminal can be determined; the intelligent contract system compares the user signature information carried in the current data processing instruction with the pre-stored real user signature of the user terminal, and the identity of the user terminal can be verified.
S202, responding to the verification that the user signature information passes, and detecting whether the execution result of the data processing instruction depends on the data value of the target data to obtain a detection result.
Illustratively, the intelligent contract system determines, according to a blockchain address a carried in the data processing instruction, that the user terminal corresponding to the blockchain address a is the user terminal a, and obtains, from the intelligent contract corresponding to the user terminal a, that the real user signature of the user terminal a is a 1; at this time, if the user signature information carried in the data processing instruction is a1, it is determined that the user signature information is verified.
S203, responding to the verification failure of the user signature information, and refusing to execute the data processing instruction.
Illustratively, the intelligent contract system determines, according to a blockchain address a carried in the data processing instruction, that the user terminal corresponding to the blockchain address a is the user terminal a, and obtains, from the intelligent contract corresponding to the user terminal a, that the real user signature of the user terminal a is a 1; at this time, if the user signature information carried in the data processing instruction is B1, it is determined that the user signature information verification fails, and the intelligent contract system refuses to execute the data processing instruction.
Specifically, for the step S202, in an optional implementation, as shown in fig. 3, fig. 3 is a schematic flow chart illustrating a method for detecting whether an execution result of a data processing instruction provided in an embodiment of the present application depends on a data value of target data, where, when the step S202 is executed, the method includes steps S301 to S302; specifically, the method comprises the following steps:
s301, when the step of executing the data processing instruction does not need to perform arithmetic processing on the data value of the target data, determining that the execution result of the data processing instruction does not depend on the data value of the target data.
Specifically, when the execution step of the data processing instruction does not need to perform the operation processing on the data value of the target data, that is, no matter how many specific data values of the target data have an influence on the execution result of the data processing instruction, it may be determined that the execution result of the data processing instruction does not depend on the data value of the target data.
For exemplary illustration, the data processing instructions are: for example, the target data X is modified to be data X2, and at this time, when the data processing instruction is executed, no operation processing is performed on the target data X, that is, no matter the specific data value of the target data X is X1 or X3, the data processing result obtained after the data processing instruction is executed is: data X2; thus, it may be determined that the result of execution of the data processing instruction does not depend on the data value of the target data.
S302, when the step of executing the data processing instruction needs to perform operation processing on the data value of the target data, determining that the execution result of the data processing instruction depends on the data value of the target data.
Specifically, when the execution step of the data processing instruction needs to perform the operation processing on the data value of the target data, that is, when the same data processing instruction is executed on target data of different data values, the obtained data processing results are different, and at this time, it may be determined that the execution result of the data processing instruction depends on the data value of the target data.
For exemplary illustration, the data processing instructions are: in the case of adding data X2 to the target data X, if the specific data value of the target data X is X1 when the data processing instruction is executed, the execution result of the data processing instruction is: x1+ X2; if the specific data value of the target data X is X3, the execution result of the data processing instruction is: x3+ X2; since the data processing results obtained when the same data processing instruction is executed for target data X of different data values are different, it can be determined that the execution result of the data processing instruction depends on the data value of the target data.
Specific operation processing methods that can be performed on the data value of the target data include, but are not limited to: the present invention is not limited to the specific operation processing method performed on the data value of the target data, which is a common operation processing method such as addition, subtraction, multiplication, and division.
For the specific implementation process of the above steps S103-S104, considering that when the execution result of the data processing instruction depends on the data value of the target data, if the intelligent contract system repeatedly executes the data processing instruction for multiple times, the data processing result of the target data may change accordingly, and based on this, to avoid the above situation, as shown in fig. 4, fig. 4 shows a flowchart of a method for performing lock protection on the target data according to a parameter updating manner of a lock parameter, provided by an embodiment of the present application, where in step S104, after parameter information carried in the data processing instruction passes verification, the method includes steps S401-S402; specifically, the method comprises the following steps:
s401, according to a preset parameter updating mode, updating the parameter value of the locking parameter at the first moment to obtain a parameter updating result of the locking parameter at the second moment.
Here, the predetermined parameter updating method may be used to represent a parameter updating method for performing a stepwise updating on a parameter value of the locking parameter according to a preset fixed step length, and the specific value of the fixed step length is not limited in any way in the embodiment of the present application.
Here, the second time is used to represent the current time when the parameter value of the locking parameter at the first time completes the parameter update.
For example, taking an example that the predetermined parameter updating manner is to update the parameter value of the lock parameter in a stepwise manner with a step size of 1, if the parameter value of the lock parameter at the first time is a number 4, after updating the parameter value of the lock parameter at the first time according to the predetermined parameter updating manner, a parameter updating result of the lock parameter at the second time (i.e. the current time when the parameter is updated) can be obtained as follows: number 5.
S402, according to the parameter updating result of the locking parameter at the second moment, locking protection is carried out on the target data.
Here, for the case where the intelligent contract system repeatedly receives the same data processing instruction multiple times, it should be noted that: when the user terminal has communication delay or data transmission is blocked, the user terminal may mistakenly repeatedly send the same data processing instruction to the intelligent contract system; when the intelligent contract system is subjected to replay attack (i.e., the eavesdropper sends the eavesdropped data to the receiver without any change), the eavesdropper may repeatedly send the eavesdropped data processing instructions to the intelligent contract system.
Specifically, taking the fixed step length of 1 as an example, after the parameter information carried in the data processing instruction passes verification, adding 1 to the parameter value L of the locking parameter to obtain a parameter update result of the locking parameter at the second time as L +1, and performing data processing on the target data according to the data processing instruction to obtain a data processing result; at this time, after the data processing and the parameter updating are completed, responding to a parameter query request of the user terminal for the locking parameter, and sending the updated parameter value L +1 to the user terminal as a parameter value of the locking parameter at the first time; based on this, if the intelligent contract system receives the repeated data processing instruction again (that is, the carried parameter is still the data processing instruction of the parameter value L before the lock parameter is updated), since the parameter of the lock parameter at the current time is L +1 (that is, the parameter value of the lock parameter at the first time), when the parameter information carried in the repeatedly received data processing instruction is verified again according to the parameter value of the lock parameter at the first time in step S103, the repeated data processing instruction cannot pass the verification, so that the intelligent contract system can be effectively protected from the replay attack, and meanwhile, the idempotent function of the external interface can be realized, so as to prevent multiple repeated modifications to the target data caused by the misoperation of the user terminal.
With respect to the specific implementation process of the above steps S103-S104, considering that when the execution result of the data processing instruction does not depend on the data value of the target data, the data processing result will not change even if the data processing instruction is repeatedly executed, as shown in fig. 5, fig. 5 shows a flowchart of a method for directly executing the data processing instruction provided by the embodiment of the present application, where, in step S103, after receiving the data processing instruction of the user terminal for the target data, the method includes steps S501-S502; specifically, the method comprises the following steps:
s501, when the execution result of the data processing instruction is determined to be irrelevant to the data value of the target data, the data processing instruction is executed aiming at the target data, and the execution result of the data processing instruction is obtained.
And S502, storing the execution result into a target contract corresponding to the user terminal.
Specifically, regarding the above steps S501 to S502, it should be noted that: when the execution result of the data processing instruction is determined to be irrelevant to the data value of the target data, at this time, the data processing result cannot be changed even if the data processing instruction is repeatedly executed, that is, the realization of the intelligent contract interface idempotent function cannot be influenced even if the parameter verification is not performed on the locking parameter (which is equivalent to that the data processing result sent to the user terminal by the intelligent contract system cannot be changed because the data processing instruction is repeatedly sent for many times); based on this, when it is determined that the execution result of the data processing instruction is not related to the data value of the target data, it is possible to directly execute the data processing instruction without verifying whether the lock parameter is the same, and transmit the data processing result to the user terminal.
Based on the data processing method based on the block chain provided by the embodiment of the application, a data protection request of a user terminal for target data is responded, and a locking parameter for protecting the target data is configured for the target data; responding to a parameter query request of the user terminal for the locking parameter, and sending the parameter value of the locking parameter at the first moment to the user terminal; receiving a data processing instruction of a user terminal aiming at target data, and verifying parameter information carried in the data processing instruction according to a parameter value of a locking parameter at a first moment when the execution result of the data processing instruction is determined to depend on the data value of the target data; and responding that the parameter information carried in the data processing instruction passes verification, and executing the data processing instruction aiming at the target data to obtain an execution result of the data processing instruction.
By the method, the realization of the interface idempotent function can get rid of the dependency on specific data processing logic, and the user terminal can conveniently access the intelligent contract system.
Based on the same inventive concept, the present application further provides a data processing apparatus corresponding to the above data processing method based on a block chain, and as the principle of the data processing apparatus in the embodiment of the present application for solving the problem is similar to that of the above data processing method based on a block chain in the embodiment of the present application, the implementation of the data processing apparatus may refer to the implementation of the above data processing method, and repeated details are omitted.
