Embodiments of the present invention will be described below with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the execution subject of the embodiment of the present invention may be various types of terminals or servers, where the terminal may be a terminal capable of performing data processing, such as a smart phone, a tablet computer, a wearable Device, a computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the server may be a server capable of performing data processing, such as a text server and a database server, and the present invention is not limited thereto.
For convenience of description, the following method embodiments take the execution subject as an example for further description.
Referring to fig. 1, a flow chart of a data processing method according to an embodiment of the present invention is shown, where the data processing method shown in fig. 1 includes:
s101, obtaining user data block states of all terminals in a terminal set, selecting a target terminal from the terminal set according to the user data block states, and generating a user data block chain according to a user data block in the target terminal.
It should be noted that the terminal set may be a terminal set participating in recording user data. Each terminal in the terminal set can store and record the user data.
It should be further noted that the user data block state may be a parameter such as a speed, a correct rate, an error rate, and the like for the server to generate the user data block according to each terminal in the terminal set, and the user data block state may be used to analyze a recording quality of each terminal recording the user data block.
In some possible embodiments, the server may use the speed at which each terminal generates the user data block as the user data block status. Specifically, the server may sort the speed at which each terminal in the terminal set generates the user data block in the order from fast to slow, and then select the terminal corresponding to the terminal with the highest speed at which the user data block is generated as the target terminal.
In some possible embodiments, the server may also use the correct rate or the error rate of the user data block generated by each terminal as the user data block state, then sort the user data blocks according to the correct rate or the error rate of the user data block generated by each terminal in the terminal set, and then select the target terminal according to the sorting result.
In some possible embodiments, the server may further use a generation quality obtained by analyzing a speed, a correct rate, and an error rate of each terminal in the terminal set to generate the user data block as the user data block status. Of course, the above-mentioned modes are only examples, not exhaustive, and include but are not limited to the above-mentioned alternatives.
It should be noted that the user data block may be a block into which one or more user data generated within a period of time are packed for the target terminal.
In specific implementation, the server may obtain a plurality of user data blocks in the target terminal after selecting the target terminal according to the state of the user data blocks, and the server may associate each user data block according to a time sequence and generate the user data block chain.
And S102, storing the user data block chain and sending the user data block chain to each terminal in the terminal set.
It should be noted that the server may store the user data blockchain in a storage component of the server after generating the user data blockchain. Further, the server may also send the user data block chain to each terminal in the terminal set, and each terminal in the terminal set may verify the integrity of data of the user data block chain by using the user data block chain.
S103, when a data verification request of a request terminal is received, calculating user data corresponding to the user data block chain according to the data verification request to obtain a verification hash value.
The data verification request is a request for verifying a first determination result, and the first determination result is a result of determining the integrity of the user data by the request terminal.
In a specific implementation, the requesting terminal may be one of the terminals in the terminal set, or the requesting terminal may also be a terminal that receives the user data block chain through any one of the terminals in the terminal set, or the requesting terminal may also be any other terminal, which is not limited in this embodiment of the present invention.
In some possible embodiments, the requesting terminal may perform integrity verification on the user data in the user data blockchain according to the user data blockchain.
Specifically, the requesting terminal may calculate the user data to obtain a verification hash value of the terminal side, match the verification hash value of the terminal side with an initial hash value in a user data block chain, and if a matching result indicates that the verification hash value of the terminal side is the same as the initial hash value, the requesting terminal may generate a first determination result, where the first determination result may be a result of determining that the integrity of the user data is not modified by the user data.
Wherein, if the matching result indicates that the verification hash value at the terminal side is not the same as the initial hash value, the requesting terminal may generate a first determination result, and the first determination result may be a result of determining that the integrity of the user data is that the user data is modified.
In some possible embodiments, after the requesting terminal generates the first determination result, it may request the server to verify whether the first determination result is correct. Specifically, the requesting terminal may send a data verification request to the server, where the data verification request may include the first determination result, and the first determination result may include a verification hash value at the terminal side.
In some possible embodiments, when receiving a data verification request from a request terminal, the server may calculate, according to the data verification request, user data corresponding to a user data block chain in the server, to obtain a verification hash value on the server side.
And S104, matching the initial hash value with the verification hash value, and determining the integrity of the user data according to a matching result.
Wherein the integrity is used for indicating whether the user data is modified, and the initial hash value is a hash value in the user data block chain.
It should be noted that the initial hash value may be a hash value in the user data chunk chain. The server may generate a hash value corresponding to user data of the user data block chain at the same time when generating the user data block chain according to the user data block in the target terminal, and add the hash value corresponding to the user data block chain.
In some possible embodiments, the specific way for the server to match the initial hash value with the verification hash value may be: the server determines whether the initial hash value and the verification hash value are the same.
Further, if the matching result determines that the initial hash value is the same as the verification hash value for the server, the server may further determine that the integrity of the user data is that the user data is not modified. If the matching result determines that the initial hash value is different from the verification hash value for the server, the server may further determine that the integrity of the user data is that the user data is modified.
It can be seen that, in the embodiment of the present invention, a user data block chain is generated by selecting a target terminal, then the user data block chain is stored and sent to each terminal in a terminal set, when a data verification request of a request terminal is received, a verification hash value is obtained by calculating user data corresponding to the user data block chain according to the data verification request, finally, an initial hash value is matched with the verification hash value, and the integrity of the user data is determined according to a matching result, and the integrity of the user data corresponding to the user data block chain can be effectively verified by using the hash value.

s201, obtaining user data block states of all terminals in a terminal set, selecting a target terminal from the terminal set according to the user data block states, and generating a user data block chain according to a user data block in the target terminal.
Optionally, the server may further obtain a user identifier of each user data in the target terminal, and determine work information corresponding to the user identifier of each user data; determining the capability level corresponding to the user identification of each user data according to the working information; and if the capability level of the user identifier is within a preset range, executing the content corresponding to the recommendation information when the recommendation information of the user identifier with the capability level within the preset range is received.
It should be noted that the user identifier may be a user name, a user account, an identity ID of the user, a user avatar, and the like, which is not limited in this embodiment of the present invention.
The target terminal may include user data corresponding to a plurality of user identifiers. For example, user data 1 may represent data corresponding to user identity a, user data 2 may represent data corresponding to user data B, and so on.
It should be further noted that the work information may be, for example, a workload, a work intensity, a processing speed of a work corresponding to the user identifier, and the like, which is not limited in this embodiment of the present invention.
For example, the server may obtain the user data block state of each terminal in the terminal set, and at the same time, obtain the user identifier corresponding to each user data in the target terminal, where user data 1 corresponds to user identifier a, user data 2 corresponds to user identifier B, and user data 3 corresponds to user identifier C. The terminal may record in advance the work information (e.g., workload) corresponding to each of the user identifier a, the user identifier B, and the user identifier C.
The workload corresponding to the user identifier a is, for example, 50, the workload corresponding to the user identifier B is, for example, 20, and the workload corresponding to the user identifier C is, for example, 70. If the server presets the user identifier with the workload of 0-20, the corresponding capability level is a, the user identifier with the workload of 21-50, the corresponding capability level is B, the user identifier with the workload of 51 or above, the corresponding capability level is C, the capability level corresponding to the user identifier a is B, the capability level corresponding to the user identifier B is a, and the capability level corresponding to the user identifier C is C.
Further, the preset range of the capability level may be b or above. Therefore, the server may determine that the user identity a and the user identity C are user identities with the capability level within a preset range.
Further, if the server receives recommendation information (e.g., a data update method, a data verification method, etc.) sent to the server by the user identifier a or the user identifier C, the server may execute the content corresponding to the recommendation information according to the recommendation information (e.g., adjust the data update method of the server according to the recommended data update method, etc.).
In some possible embodiments, when the server may further receive user data corresponding to the user identifier a or the user identifier C, if the user data is data that needs to be executed by the server, the server may directly execute the user data corresponding to the user identifier a or the user identifier C.
S202, storing the user data block chain, and sending the user data block chain to each terminal in the terminal set.
It should be noted that step S202 in the embodiment of the present invention may be implemented according to step S102 in the above method embodiment, and the specific implementation process may refer to the related description of the above method embodiment, which is not described herein again.
S203, when a data verification request of a request terminal is received, user information corresponding to the request terminal is obtained.
Wherein, the user information at least comprises the user identification of the request terminal.
The data verification request is a request for verifying a first determination result, and the first determination result is a result of determining the integrity of the user data by the request terminal.
It should be noted that the user information corresponding to the requesting terminal may at least include the user identifier of the requesting terminal. Alternatively, the user information may further include the number, size, and the like of the user data of the requesting terminal in the server, which is not limited in the present invention.
In some possible embodiments, the server may obtain the user data of the requesting terminal according to the data verification request when receiving the data verification request sent by the requesting terminal. And the amount, size, etc. of the user data of the requesting terminal in the server.
S204, calling a storage component to acquire the security information corresponding to the user identification of the request terminal stored in the storage component.
It should be noted that the storage component may be a storage medium dedicated to storing data in the server.
It should be further noted that the security information corresponding to the user identifier of the requesting terminal may be pre-stored in the storage component of the server, and the server may determine whether the data verification request of the requesting terminal is an illegal request according to the security information.
The security information may be information for determining whether the requesting terminal is a secure terminal authenticated by the server, or the like.
S205, if the safety information corresponding to the user identifier of the request terminal meets the preset condition, calculating the user data corresponding to the user data block chain according to the data verification request to obtain a verification hash value.
For example, the security information may include a security key of the requesting terminal, and the preset condition may be security authentication of the server itself. If the server can pass the security authentication of the server itself according to the security key of the requesting terminal, the server can determine that the requesting terminal is a secure terminal.
In some possible embodiments, after determining that the requesting terminal is a secure terminal, the server may calculate the verification hash value for the user data corresponding to the user data blockchain according to the data verification request.
If the server determines that the requesting terminal is not a secure terminal, the server may not perform any processing on the user data corresponding to the user data blockchain, and the server may further send a notification message that the requesting terminal is not authenticated to the requesting terminal.
Optionally, the user data corresponding to the user data block chain at least includes: first user data and second user data, the second user data having an association with the first user data.
It should be noted that the association between the second user data and the first user data may be a chronological association. For example, the first user data is the first data and the second user data is the second data.
It should be noted that the user data may further include third user data, fourth user data, and so on, and when there are more than 2 user data, the processing method may be similar to the processing method of the 2 user data, and the embodiment of the present invention does not limit this.
Optionally, the calculating the verification hash value for the user data corresponding to the user data block chain according to the data verification request specifically includes: calculating to obtain a first hash value according to first user data in the user data block chain; and calculating to obtain a verification hash value according to the second user data in the user data block chain and the first hash value.
In some possible embodiments, the first user data may be earlier data and the second user data may be later data. The server may calculate the first user data by using a hash algorithm to obtain a corresponding first hash value, then may calculate a corresponding second hash value by using a hash algorithm according to the second user data, and then may generate the verification hash value according to the first hash value and the second hash value.
In some possible embodiments, the server may further calculate the first user data by using a hash algorithm to obtain a corresponding first hash value, and then the server may obtain the verification hash value by using a hash algorithm according to the second user data and the first hash value.
S206, matching the initial hash value with the verification hash value, and determining the integrity of the user data according to the matching result.
It should be noted that step S206 in the embodiment of the present invention may be implemented according to step S104 in the above method embodiment, and the specific implementation process may refer to the related description of the above method embodiment, which is not described herein again.
S207, the determined integrity of the user data is compared with the first determination result to determine the correctness of the first determination result.
Wherein the first determination result is a result of the requesting terminal determining the integrity of the user data.
In some possible embodiments, the server may determine that the integrity of the user data is that the user data is not modified, and if the first determination result is that the user data is also not modified, the server may determine that the first determination result is correct. Alternatively, the server may determine that the integrity of the user data is such that the user data is modified, and if the first determination result is such that the user data is also modified, the server may determine that the first determination result is also correct.
In some possible embodiments, the server may determine that the integrity of the user data is that the user data is not modified, and if the first determination result is that the user data is also modified, the server may determine that the first determination result is erroneous. Alternatively, the server may determine that the integrity of the user data is that the user data is modified, and if the first determination result is that the user data is not modified, the server may determine that the first determination result is also erroneous.

Wherein, if the first determination result is correct, the notification message may be a message for notifying that the first determination result is correct. If the first determination result is erroneous, the notification message may be a message for notifying that the first determination result is erroneous.
It can be seen that, in the embodiment of the present invention, a target terminal is selected to generate a user data block chain, the user data block chain is stored and sent to each terminal in a terminal set, when a data verification request of a request terminal is received, if security information of a user identifier of the request terminal meets a preset condition, a verification hash value is calculated for user data corresponding to the user data block chain according to the data verification request, an initial hash value is matched with the verification hash value, the integrity of the user data is determined according to a matching result, and the determination result is sent to the request terminal, so that the integrity of the user data corresponding to the user data block chain can be effectively verified by using the hash value, and the verified result is sent to the request terminal to help the request terminal to determine the correctness of the determination result of the request terminal, the reliability of the determination result of the requesting terminal itself is enhanced.
