Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
An exemplary embodiment of the present disclosure provides a method for data synchronization, which may be implemented by a terminal and a server together, where the terminal may be a terminal having a data synchronization function, such as a mobile phone, a tablet computer, and the like. The server may be a background server for the data synchronization function.
The terminal may include a processor, memory, transceiver, etc. The processor may be a CPU (Central Processing Unit), and may be used to determine the related Processing of the current login manner of the terminal. The Memory may be a RAM (Random Access Memory), a Flash (Flash Memory), and the like, and may be configured to store received data, data required by the processing procedure, data generated in the processing procedure, and the like, such as data sent by the server. The transceiver may be used for data transmission with other devices, for example, to receive data not stored in the terminal transmitted by the server, and may include an antenna, a matching circuit, a modem, and the like.
The server may include a processor, memory, transceiver, etc. The processor may be a CPU or the like, and may be used for processing related to determining a current login manner of the terminal. The memory may be a RAM, a Flash, or the like, and may be used to store received data, data required by the processing procedure, data generated in the processing procedure, or the like, such as data backed up by the terminal. The transceiver may be used for data transmission with a terminal or other server, e.g., to transmit data not stored in the terminal to the terminal, and may include an antenna, matching circuit, modem, etc.
The process flow shown in fig. 1 will be described in detail below with reference to the embodiments, and the contents may be as follows:
in step 101, the terminal determines that data not stored in the terminal exists in the server.
In implementation, a user can trigger the terminal to log in the server through operation in the process of using the terminal, wherein the terminal can log in the server through a common login mode or a safe login mode. Specifically, when a user wants to trigger the terminal to log in the server, the user can display a login mode selection interface by operating the trigger terminal, wherein a common login button corresponding to a common login mode and a safety login button corresponding to a safety login mode can be displayed in the login mode selection interface, and the user can select the corresponding login button according to the needs of the user. When a user clicks a common login button, the terminal can log in the server through user name and password authentication, when the user clicks a safe login button, the terminal performs two-step authentication (such as inputting an authentication code) besides authentication through the user name and the password, wherein in the login process, when the terminal sends a login request to the server, the login request can carry the user name and the password (and the authentication code), in addition, the login request can also carry a login mode identifier, and after the login is successful, the terminal and the server can record the current login mode of the terminal.
After the terminal logs in the server, the terminal may detect whether data that is not stored in the terminal exists in the server (i.e., data that is backed up to the server by another terminal), and when data that is not stored in the terminal exists in the server, the terminal may determine that data that is not stored in the terminal exists in the server.
In step 102, if the current login mode is a secure login mode, the terminal sends a data download request to the server, wherein the secure login mode is a login mode for performing two-step authentication.
In implementation, when the terminal determines that data which is not stored in the terminal exists in the server, whether the current login mode of the terminal is a normal login mode or a secure login mode may be determined, and if the current login mode is the secure login mode, the terminal may send a data download request to the server, as shown in fig. 2.
In step 103, if the current login mode is a normal login mode, the terminal does not send a data download request to the server, where the normal login mode is a login mode without performing the two-step authentication.
In implementation, when the terminal determines that data which is not stored in the terminal exists in the server, if the current login mode of the terminal is a common login mode, the terminal may not send a data download request to the server any more. In this way, when the current login mode is a login mode with low security, the terminal can not download data to the server any more so as to protect personal data stored in the server.
Optionally, the terminal may further upload data that is not backed up in the server and is stored in the terminal to the server, and correspondingly, the terminal may further perform the following processing: when detecting that data which are not backed up in the server exist in the terminal, sending a data uploading request to the server, wherein the data uploading request carries the data to be backed up.
In implementation, in the using process of the terminal, the terminal may further detect whether new data is generated in the terminal, that is, whether data that is not backed up in the server exists in the terminal, and when detecting that data that is not backed up in the server exists in the terminal, the terminal may send a data upload request to the server, where the data upload request may carry data to be backed up.
Optionally, the terminal may determine whether data not stored in the terminal exists in the server by querying the server, and accordingly, the processing procedure of step 101 may be as follows: sending a data inquiry request to a server every time a preset inquiry period is reached; when a data confirmation message corresponding to the data inquiry request transmitted by the server is received, it is determined that data not stored in the terminal exists in the server.
In implementation, the terminal may be preset with an inquiry period, and each time the preset inquiry period is reached, the terminal may send a data inquiry request to the server, where the data inquiry request is used to inquire whether data that is not stored in the terminal exists in the server. Correspondingly, after the server receives the data inquiry request, if data which is not stored in the terminal exists in the server, the server can send a data confirmation message corresponding to the data inquiry request to the terminal. The terminal may receive a data confirmation message corresponding to the data inquiry request sent by the server, and at this time, the terminal may determine that data not stored in the terminal exists in the server.
In step 104, the server receives a data download request sent by the terminal.
In implementation, after the terminal sends the data download request to the server, the server may receive the data download request sent by the terminal.
In step 105, if the current login mode of the terminal is a secure login mode, the server sends data not stored in the terminal to the terminal, wherein the secure login mode is a login mode for performing two-step authentication.
In implementation, after receiving a data download request sent by a terminal, a server may determine whether a current login manner of the terminal is a normal login manner or a secure login manner, and if the current login manner is the secure login manner, the server may respond to the data download request sent by the terminal, that is, the server may send data that is not stored in the terminal to the terminal.
In step 106, if the current login mode of the terminal is a normal login mode, the server does not send data which is not stored in the terminal to the terminal, wherein the normal login mode is a login mode without two-step verification.
In implementation, after the server receives the data download request sent by the terminal, if the current login mode of the terminal is the normal login mode, the server may not respond to the data download request sent by the terminal, that is, no data not stored in the terminal is sent to the terminal. In this way, when the current login method is a login method with low security, data which is not stored in the terminal is not sent to the terminal so as to protect personal data stored in the server.
Optionally, for a situation that the terminal sends a data upload request to the server, correspondingly, the server may further perform the following processing: receiving a data uploading request sent by a terminal, wherein the data uploading request carries data to be backed up; and storing the data to be backed up carried in the data uploading request.
In implementation, after the terminal sends the data upload request to the server, the server may receive the data upload request sent by the terminal, and may analyze the data upload request to obtain the data to be backed up carried in the data upload request. After the data to be backed up is acquired, the server can store the data to be backed up carried in the data uploading request so as to backup the data to be backed up.
Optionally, for a case that the terminal sends a data query request to the server, correspondingly, the server may further perform the following processing: when a data inquiry request sent by a terminal is received, if data which is not stored in the terminal exists in a server, a data confirmation message corresponding to the data inquiry request is sent to the terminal.
In implementation, after the terminal sends the data query request to the server, the server may receive the data query request sent by the terminal, and further, the server may determine whether data that is not stored in the terminal exists in the server, and if data that is not stored in the terminal exists in the server, the server may send a data confirmation message corresponding to the data query request to the terminal, so that after the terminal receives the data confirmation message, it is determined that data that is not stored in the terminal exists in the server.
In step 107, when data not stored in the terminal transmitted by the server is received, the data not stored in the terminal is stored.
In an implementation, when the server sends data not stored in the terminal to the terminal, after the server sends the data not stored in the terminal to the terminal, the terminal may receive the data not stored in the terminal sent by the server, and further, the terminal may store the data not stored in the terminal.
According to the scheme, the terminal and the server simultaneously support two login modes, namely a common login mode and a safe login mode, when the current login mode is the safe login mode, the terminal can download data which are not stored in the terminal to the server, when the current login mode is the common login mode, the terminal cannot download the data which are not stored in the terminal to the server, and no matter whether the current login mode is the safe login mode or the common login mode, the terminal can upload data which are not backed up in the server to the server. Therefore, when the terminal receiving the verification code is not at the user, the terminal can successfully log in the server so as to realize the backup of the data in the terminal. When the current login mode is the common login mode, the terminal is not allowed to download the data in the server, so that the safety can be improved.
In the embodiment of the disclosure, when the server receives a data download request sent by the terminal, if the current login mode of the terminal is a secure login mode, the server may send data that is not stored in the terminal to the terminal, and if the current login mode is a normal login mode, the data that is not stored in the terminal is no longer sent to the terminal, where the normal login mode is a login mode in which two-step authentication is not performed, and the secure login mode is a login mode in which two-step authentication is performed. Thus, when the terminal is in a normal login mode, the server does not allow the terminal to download the personal data stored in the server, and therefore, the security can be improved.

a receiving module 310, configured to receive a data download request sent by a terminal;
a sending module 320, configured to send data that is not stored in the terminal to the terminal if the current login manner of the terminal is a secure login manner, where the secure login manner is a login manner for performing two-step verification; and if the current login mode of the terminal is a common login mode, no data which are not stored in the terminal are sent to the terminal, wherein the common login mode is a login mode without two-step verification.

With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
In the embodiment of the disclosure, when the server receives a data download request sent by the terminal, if the current login mode of the terminal is a secure login mode, the server may send data that is not stored in the terminal to the terminal, and if the current login mode is a normal login mode, the data that is not stored in the terminal is no longer sent to the terminal, where the normal login mode is a login mode in which two-step authentication is not performed, and the secure login mode is a login mode in which two-step authentication is performed. Thus, when the terminal is in a normal login mode, the server does not allow the terminal to download the personal data stored in the server, and therefore, the security can be improved.
