Technical Field

The present invention relates to the field of data processing technologies, and in particular, to a method and an apparatus for data processing, an electronic device, and a storage medium.

Background

At present, in order to ensure the synchronization of data of two parties in business cooperation, after a data set of one party is changed, the data stored in a local terminal needs to be updated in time, and the data of the other party also needs to be updated in time, the data change time of one party is uncontrollable, so the data change time of the two parties is difficult to align, in the process, the data of the two parties needs to be updated in real time based on a privacy request mode, so that the synchronization of the data of the two parties can be ensured under the condition of ensuring the data privacy.

In the privacy committing process, each piece of data to be compared needs to be processed by the keys of both parties respectively, and after the processing is finished by the keys of both parties respectively, the comparison operation can be performed on the data. In the prior art, both data are stored in only one data set, and the data set usually has a large data size, so when one data set is changed, all the changed data need to be compared with all the data in the other data set, and obviously, the comparison takes much time. The privacy delivery process consumes much time, and any party cannot update data in time.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

In the embodiment of the invention, the two parties needing data synchronization are called two ends, and all data held by each end is called a data set.

In the embodiment of the invention, the data sets held by each end are divided into commonly held data sets and non-commonly held data sets in advance. Intersection data of the held data sets at the two ends are stored in the commonly held data set, and the intersection data are identical data obtained by comparing the held data sets at the two ends; the non-commonly held data sets store non-intersection data of the held data sets at the two ends, and the non-intersection data is non-identical data obtained by comparing the held data sets at the two ends.

The comparison is realized by a privacy intersection method, the privacy intersection method is characterized in that the intersection of data sets held by two parties or multiple parties is solved on the premise of protecting the privacy of multiple parties, and the privacy intersection method does not reveal the content and information except the intersection of any party while solving the intersection. Therefore, in the present invention, the process of "comparing" the data at both ends is substantially a process of comparing the data of both ends without revealing the data of both ends.

Of course, the present invention does not limit the obtaining manner of the commonly held data set and the non-commonly held data set pre-stored at both ends performing data synchronization, and any possible manner may be applied to the present invention. For example, the first generation of the commonly-held data set and the non-commonly-held data set by the home terminal performing data synchronization may be performed by performing privacy intersection on all data in the data set of the home terminal and all data at the other end performing data synchronization to obtain an intersection result set, then taking data belonging to the intersection result set of the home terminal as the commonly-held data set of the home terminal, and taking the remaining other data of the home terminal as the non-commonly-held data set of the home terminal; the other end, which performs data synchronization, generates its commonly-owned data set and non-commonly-owned data set in the same manner. For another example, directly obtained data commonly held by both ends is stored in each end as a commonly held data set, and directly obtained data not commonly held by both ends is stored in each end as a non-commonly held data set, where each end may be various types of terminals, such as a desktop computer, a notebook computer, a smart phone, and the like.

The two ends needing data synchronization can be two parties carrying out service cooperation.

According to a first aspect of the embodiment of the present invention, refer to fig. 1, which is a flowchart of a first method for data processing according to the embodiment of the present invention. The embodiment is applied to one end of data sets that are changed in two ends of data synchronization, where the data sets stored at the end include a commonly-held data set and a non-commonly-held data set, and the method shown in fig. 1 specifically includes:

and S110, detecting that the data of the local terminal is changed.

The data processing method provided by the embodiment of the invention can be executed by a server and a user terminal, and specifically can be executed by a desktop computer, a notebook computer, a smart phone, a smart tablet and the like.

The two ends of the data synchronization can be any two ends needing data synchronization. In one example, the two ends are two parties that collaborate on the service.

The local stored data set stores any data that needs to be synchronized with the other end authentication. In one example, the data set may store local information related to the user, such as a mobile phone number, an identification number, a device ID, and the like of the user.

The change of the data of the local terminal can be adding one or more data, deleting one or more data, or modifying one or more data sets. In fact, the process of "modifying" is a combination of "deleting" + "adding", and modifying one data is to delete one data and add one data, so the present application only describes "adding" and "deleting" in detail, and does not describe "modifying" in detail, which can be regarded as performing the process of "adding" and "deleting" once respectively.

And S120, judging whether the changed data meets the preset conditions or not according to the change.

If the change is adding data, judging whether the added data meets a first preset condition; if the change is deleting the data, judging whether the deleted data meets a second preset condition; if the change is the modification of the data, corresponding to the modification operation, judging whether the deleted data corresponding to the modification operation meets a second preset condition, and judging whether the added data corresponding to the modification operation meets a first preset condition.

And S130, if so, updating the data in the commonly held data set and/or the non-commonly held data set of the local terminal.

In the embodiment of the invention, the data set is divided into the commonly held data set and the non-commonly held data set, so that when the data set is updated, part of data of the local terminal is preferentially processed, and all data of the local terminal only needs to be processed under individual conditions, thereby ensuring timely synchronous updating of the data of the local terminal and greatly improving the efficiency of data processing.

In one possible implementation, referring to fig. 2, when the change in the embodiment shown in fig. 1 is an add operation, step S120 shown in fig. 1 may include:

s1201, when the adding operation is changed, judging whether the added first data meet a first preset condition, wherein the first preset condition is that the first data exist in a non-commonly-held data set of a local terminal; alternatively, the first data does not exist in the co-owned data set and the non-co-owned data set of the local end.

Step S130 shown in fig. 1 may include:

s1301, when a first preset condition is met, a comparison request of first data is sent to an opposite terminal; the comparison request is used for enabling the opposite terminal to compare the first data with each data in the data set stored by the opposite terminal to obtain result information;

s1302, updating the data in the co-owned data set and/or the non-co-owned data set of the local terminal in response to the result information sent by the opposite terminal.

In this embodiment, the change is an add operation, and the change in the data may be an add of the first data. The first data is determined according to the change condition of the actual data of the home terminal, in one example, when the home terminal detects that a bound mobile phone number is newly added to a user, the change means that the mobile phone number to be bound by the user is newly added, and the first data is the mobile phone number newly bound by the user. Of course, in one change, only one item of information may be changed, for example, a newly bound mobile phone number is added, or two or more items of information may be changed, for example, a newly bound mobile phone number and an identity card number are added.

When the first preset condition is: when the first data exists in the non-commonly held data set of the local terminal, it indicates that the first data is data whose data is different from the data compared by the opposite terminal before, and at this time, the data set of the opposite terminal may have been changed, and a comparison request of the first data needs to be sent to the opposite terminal. For example, if the change is to add data a, and it is determined that data a exists in the non-commonly-owned dataset of the local peer, and the data a satisfies the first preset condition, it indicates that data a is data whose data is different from that compared after the comparison between the local peer and the peer, and a comparison request for data a needs to be sent to the peer.

When the first preset condition is: when the first data does not exist in the commonly held data set and the non-commonly held data set of the local terminal, the first data is the newly added data, at this time, the first data needs to be compared with the data set of the opposite terminal to judge whether the first data is the data commonly held by the two terminals, and therefore the data set of the local terminal is updated according to the judgment result. For example, if the change is to add data B, and it is determined that data B does not exist in the shared data set and the non-shared data set of the local terminal, indicating that data B is newly added data, it is necessary to send a comparison request for data B to the opposite terminal.

The comparison request in the present invention is actually a privacy request, and the data comparison is performed in a privacy request manner, that is, the data of both parties are compared without revealing the data in the data sets held by both parties.

The result information may be that the first data is data held by both ends, or that the first data is not data held by both ends. When the opposite terminal compares the first data with each data in the data set stored by the opposite terminal, if the compared data are the same, the first data are data held by both terminals; if the comparison data are not the same, namely the comparison data are different, the first data are not the data held by both ends together.

And when the first data exists in the non-commonly-held data set of the local terminal and the result information is that the first data is the data commonly held by the two terminals, updating the data in the commonly-held data set and the non-commonly-held data set of the local terminal.

In addition, when the first data exists in the non-commonly-owned data set of the local terminal and the result information indicates that the first data is not data commonly owned by both terminals, the first data should be added to the non-commonly-owned data set.

And when the first data does not exist in the commonly held data set and the non-commonly held data set of the local terminal and the result information is that the first data is the data commonly held by the two terminals, updating the data in the commonly held data set of the local terminal.

And when the first data does not exist in the commonly held data set and the non-commonly held data set of the local terminal and the result information is that the first data is not the data commonly held by the two terminals, updating the data in the non-commonly held data set of the local terminal.

In addition, if the first data does not satisfy the first preset condition, that is, the first data exists in the commonly-held data set of the local terminal, which indicates that the first data is the data whose data are compared to be the same, at this time, it is not necessary to send a comparison request to the opposite terminal, and since the first data already exists in the commonly-held data set, it is also not necessary to add the data to the commonly-held data set.

In the embodiment of the present invention, the local end stores two data sets, that is, a commonly-held data set and a non-commonly-held data set, and only when the first data meets a first preset condition, the comparison request of the first data is sent to the opposite end, that is, only when the first data exists in the non-commonly-held data set of the local end, or does not exist in the commonly-held data set and the non-commonly-held data set of the local end, data comparison is required, instead of performing comparison processing after each data set is changed, so that the number of comparison times is greatly reduced. In the comparison process, all data does not need to be compared every time, so that the single comparison time is greatly shortened, the data processing efficiency is improved, and the data set is updated in time. The invention effectively reduces the time for comparing data and improves the efficiency, thereby meeting the system requirement of real-time intersection. Because the intersection time is greatly saved, the model statistics and the related calculation of the data can be supported in real time, and the timely synchronization of the data at the two ends can be ensured.

In one possible implementation, the result information is that the first data is data held by both ends together;

if the first data exists in the non-commonly-held data set of the local terminal, updating the data in the commonly-held data set and/or the non-commonly-held data set of the local terminal, including:

adding the first data into the commonly held data set of the local terminal, and deleting the first data from the non-commonly held data set of the local terminal to obtain an updated data set;

if the first data does not exist in the commonly-held data set and the non-commonly-held data set of the local terminal, updating the data in the commonly-held data set and/or the non-commonly-held data set of the local terminal, including:

adding the first data into a commonly held data set of the local terminal to obtain an updated data set;

the result information is that the first data is not data which is commonly held by two ends;

if the first data does not exist in the co-owned data set and the non-co-owned data set of the local end, updating the data in the co-owned data set and/or the non-co-owned data set of the local end, including:

In one example, the data a exists in the non-commonly-held data set of the local end, and the result information sent by the opposite end is that the data a is data commonly held by both ends, and in this case, the description data a is data whose data are the same after comparison, so the update operation is: and deleting the data a from the non-commonly-held data set of the local terminal and adding the data a into the commonly-held data set of the local terminal.

In one example, the data b does not exist in the commonly-owned data set and the non-commonly-owned data set of the local terminal, which indicates that the data b is brand-new data compared with the data in the local terminal data set, and when the result information sent by the opposite terminal indicates that the data b is data commonly owned by both terminals, the data b is compared and compared to obtain the same data, so the update operation is: and adding the data b into the commonly held data set of the local terminal.

In one example, the data c does not exist in the commonly held data set and the non-commonly held data set of the local end, the result information sent by the opposite end is that the data c is commonly held by both ends, and the description data c is data with different data compared after comparison, so the updating operation is as follows: and adding the data c into the non-commonly held data set of the local end.

In the embodiment of the invention, the data set of the local terminal is updated in real time based on the first preset condition and the result information which are met by the first data, so that the data set can be updated in time, and the data accuracy of the data set is ensured.

In a possible implementation manner, referring to fig. 3, when the change in the embodiment shown in fig. 1 is a deletion operation, step S120 shown in fig. 1 may include:

s1202, when the deletion operation is changed, judging whether the deleted second data meets a second preset condition, wherein the second preset condition is that the second data exists in a commonly-held data set of the local terminal; alternatively, the second data exists in a non-commonly held dataset of the local end.

Step S130 shown in fig. 1 may include:

s1303, when a second preset condition is met, if second data exists in the commonly-held data set of the local terminal, directly deleting the second data from the commonly-held data set of the local terminal to obtain an updated data set; and if the second data exists in the non-commonly-held data set of the local terminal, directly deleting the second data from the non-commonly-held data set of the local terminal to obtain an updated data set.

In this embodiment, the change is a delete operation, and the change of the data may be a delete of the second data. The second data is determined according to a change condition of the actual data of the home terminal, in one example, when the home terminal detects that a certain user account is logged off, the change means to delete an existing account that the user logs off, and the second data is the existing account that the user wants to log off. Of course, in one change, only one item of information may be changed, for example, the existing mobile phone number may be deleted, or two or more items of information may be changed, for example, the existing mobile phone number and the identification number may be deleted.

In one example, the change is deletion of data C, and if the change is deletion of data, it is determined that the data C is deleted from data already existing at the local end, and it is determined whether the data C exists in the co-owned data set or the non-co-owned data set at the local end; if the data C is judged to exist in the commonly held data set of the local terminal, directly deleting the data C from the commonly held data set of the local terminal; and if the data C is judged to exist in the non-commonly-owned data set of the local terminal, directly deleting the data C from the commonly-owned data set of the local terminal.

In the embodiment of the invention, because the local terminal stores two data sets, namely a commonly-held data set and a non-commonly-held data set, and the second data is deleted from the data set in which the second data exists by judging whether the second data exists in the commonly-held data set or the non-commonly-held data set of the local terminal, the updating operation only updates part of the data sets of the local terminal and ensures the accurate deletion of the second data, thereby ensuring the timely and accurate updating of the data sets of the local terminal.

In a possible implementation manner, when the second preset condition is met, before the step of updating the data in the co-owned data set and/or the non-co-owned data set of the local end, the method may further include: sending a comparison request of second data to the opposite terminal; and after receiving result information sent by the opposite end, executing the step of updating the data in the commonly held data set and/or the non-commonly held data set of the local end.

Whether the result information is that the second data is the data which both ends hold together or the second data is not the data which both ends hold together, the execution of the following steps is not influenced.

In this embodiment, before deleting the second data, by sending a comparison request of the second data to the opposite end, whether the second data is the commonly held data is confirmed again, and then the second data is deleted from the data set, so that robustness in the data updating process is improved.

In addition, if the change is to modify data, the step corresponding to the change to the add operation and the step corresponding to the delete operation are both executed, and in one example, when the home terminal detects that a certain user changes a bound mobile phone number, the "change" includes: and deleting the previously bound mobile phone number and the newly added and changed mobile phone number, wherein the added first data is the mobile phone number newly bound by the user, and the deleted second data is the mobile phone number previously bound by the user, so that the data set stored at the local terminal is updated.

According to a second aspect of the embodiment of the present invention, referring to fig. 4, the embodiment is applied to one of two ends of data synchronization, where the one end receives a comparison request, and the data set stored by the local end includes a commonly-held data set and a non-commonly-held data set.

The method shown in fig. 4 may specifically include:

s410, receiving the comparison request, and identifying the change operation and the change data indicated in the comparison request.

The compare request may come from the side where the data change occurred. The change operation in the request can be a deletion operation, and the change data is defined as first data corresponding to the deletion operation; the change operation in the request may also be a delete operation, and the changed data is defined as second data corresponding to the delete operation, where the first data and the second data are the same data or different data.

And S420, comparing the changed data with the data set stored in the local terminal to obtain result information.

And S430, when the result information indicates that the data are the data commonly held by the two ends, updating the data in the commonly held data set and/or the non-commonly held data set of the local end.

And S440, feeding back result information to the end sending the comparison request.

In the embodiment of the invention, after receiving the comparison request, the changed data is compared with the data set stored at the local terminal of the local terminal, and the result information is obtained and fed back to the opposite terminal (the terminal sending the comparison request), so that the real-time interaction of the information of the two parties is realized, the two parties can update the stored data sets of the two parties according to the result information fed back in real time, and the real-time synchronization of the data sets is realized.

In addition, if the result information indicates that the data is not data held by both ends, the data in the end receiving the comparison request does not need to be updated.

In the data synchronization process of the two ends, if no abnormality occurs, the data stored in the commonly held data sets of the two ends should be kept consistent, in this case, the first data may be compared with only the non-commonly held data set of the local end, and the second data may be compared with only the commonly held data set of the local end. However, if an abnormality occurs, for example, an interruption occurs in the information transmission process, so that the data of one end is not updated, and the data sets of the two ends are not consistent, in this case, the first data or the second data may be compared with the commonly-held data set and the non-commonly-held data set that have been stored by the local end, so as to ensure the accuracy of the comparison result.

In one possible implementation, the change operation is an add operation, and the change data is first data; the comparing the changed data with the data set stored in the local terminal includes: comparing the first data with data in a non-commonly-held data set stored by a local terminal;

the updating of the data in the co-owned data set and/or the non-co-owned data set of the local end includes:

and adding the first data into the commonly held data set of the local terminal, deleting the first data from the non-commonly held data set of the local terminal, and obtaining an updated data set.

In the embodiment of the invention, when the first data is compared with the data in the non-commonly-held data set stored in the local terminal and the result information shows that the first data is the data commonly held by the two terminals, the commonly-held data set and the non-commonly-held data set of the local terminal are updated in time, so that data redundancy is not caused, and the data accuracy of the data sets is further ensured.

In one possible implementation, the change operation is a delete operation, and the change data is the second data; the comparing the changed data with the data set stored in the local terminal comprises: comparing the second data with data in the common holding data set stored by the local terminal;

In the embodiment of the invention, when the second data is compared with the data in the commonly-held data set stored at the local terminal and the result information indicates that the second data is the data commonly held at the two terminals, the second data is deleted at the opposite terminal, so that the second data which is not the data commonly held at the two terminals is deleted from the commonly-held data set in time and is added into the non-commonly-held data set, thereby ensuring the timely update of the commonly-held data set and the non-commonly-held data set at the local terminal and further ensuring the data accuracy of the data set.

In the process of two-party or multi-party cooperation, the data in the data set can be user information, the data in the commonly held data set can represent users commonly owned by two parties or multiple parties of cooperation, the data in the non-commonly held data set can represent users owned by a single party in cooperation, and due to the clearly distinguished common user and single user, any party in cooperation can share the single user information in the non-commonly held data set owned by the user to other parties in cooperation, or recommend services of the cooperation party for the user according to service cooperation, so that the user can know the services of the cooperation party to solve the service requirements of the user, and meanwhile, the cooperation party can also obtain more new users, thereby realizing multi-party win-win cooperation.

The following describes a process of data processing with a specific example:

the method comprises the steps of splitting a data set stored in a data set Block A into two data sets Block M and Block P, wherein the Block M stores the same data obtained by comparing the data sets at two ends, and the Block P stores different data obtained by comparing the data sets at two ends, namely the data obtained by removing the Block M from the Block A. The sum of the data volumes of BlockM and BlockP is the sum of all data sets at the local end, i.e. the total amount of the original data set BlockA.

When detecting that the data M needs to be added, the local terminal judges whether the data M meets a first preset condition, namely whether the data M exists in Block M or not, or whether the data M does not exist in Block M and Block P or not. When the data M is checked to exist in the Block M or the check data M does not exist in the Block M and the Block P, a comparison request of the data M is sent to a remote end.

And if the data M exists in the local blockP and the received result information indicates that the data M is data commonly held by the two ends, adding the data M to the blockM and deleting the data M from the blockP.

And if the data M does not exist in the Block M and the Block P and the received result information indicates that the data M is data held by both ends, adding the data M to the Block M.

And if the data M does not exist in the Block M and the Block P and the received result information indicates that the data M is not the data held by both ends, adding the data M to the Block P.

In addition, if the data M exists in the blockap and the result information indicates that the data M is not data held by both ends, the data set does not need to be updated.

The remote end, as the end receiving the comparison request, also splits the data set stored in one data set peer block a into two data sets peer block m and peer block p, where the peer block m stores the same data obtained by comparing the data sets at the two ends, and the peer block p stores different data obtained by comparing the data sets at the two ends, that is, the data obtained by removing the peer block m from the peer block a. The sum of the data volumes of the peer block m and the peer block p is the sum of all the data sets at the end, that is, the total volume of the original data set peer block a.

And after receiving the comparison request for adding the data M, the remote end compares the data M with the data in the peer Block P to obtain result information, and if the result information indicates that the data M is data which is commonly held by the two ends, the remote end adds the data M to the peer Block M, removes the data M from the peer Block P, and feeds back the result information to the end sending the comparison request.

Detecting that the data of the local terminal is changed, judging whether the data M exists in Block M or Block P when detecting that the data M needs to be deleted, and removing the data M from the Block M when judging that the data M exists in the Block M; and when judging that the data M exists in the Block P, removing the data M from the Block P. Or when detecting that the data M needs to be deleted, sending a comparison request for deleting the data M to a remote end, and then removing the data M from the existing data set BlockM or BlockP.

And after receiving the comparison request for deleting the data M, the remote end compares the data M with the data in the peer Block M, and if the result information indicates that the data M is commonly held by the two ends, the remote end adds the data M to the peer Block P and removes the data M from the peer Block M.

In the embodiment of the invention, according to the detected change of the data set, the two ends update the respective data sets of the two ends, thereby realizing the real-time synchronization of the data sets and ensuring the accuracy of the data sets.
