The various steps of the data synchronization method are described in detail below.

In step S101, when the user needs to obtain the previously backed up data from the server, first log in to the cloud account on the terminal, and then send a synchronization request to the server. The synchronization request includes: a synchronization request instruction, a cloud account information, and feature information of a terminal that logs in to the cloud account, wherein the feature information may be one or more of the following information: SIM card information and physical address information. , address book information and communication log information.

In step S102, for each cloud account, a corresponding storage area is established in the server, and the storage area stores user information corresponding to the cloud account, data that has been backed up, and the like.

For example, as shown in FIG. 3, the pre-stored information refers to the previously backed up communication information, and the step S102 includes the following sub-steps:

S1021: Extract communication information from the synchronization request; wherein the communication information may be address book information or communication record information.

S1022: Compare the address book information with the communication information that the account has backed up;

Please refer to FIG. 4. FIG. 4 is a flowchart of a data synchronization method in an optional embodiment of the present invention. The method is mainly used in a server, and the data synchronization method comprises the following steps:

S201. Receive a synchronization request sent by the terminal, where the synchronization request carries cloud account information and feature information of the terminal.

S202. Compare the feature information with the pre-stored information to obtain a matching degree.

S203. Determine, according to the matching degree, whether the cloud account is logged in at a predetermined terminal.

S204. When the cloud account is logged in at the predetermined terminal, the synchronization data is sent to the terminal according to the synchronization request.

S205. When the cloud account is not logged in at the predetermined terminal, send a security verification request to the terminal.

S206. Receive a security verification response sent by the terminal, where the security verification response is generated by the terminal according to the security verification request.

S207. Determine, according to the security verification response, whether the verification is successful.

S208: If the verification is successful, send synchronization data to the terminal according to the synchronization request; if the verification fails, send a prompt message for verification failure.

In this step S201, when the user needs to obtain the previously backed up data from the server, first log in to the cloud account on the terminal, and then send a synchronization request to the server. The synchronization request includes: a synchronization request instruction, a cloud account information, and feature information of a terminal that logs in to the cloud account, wherein the feature information may be one or more of the following information: SIM card information and physical address information. , address book information and communication log information.

In the step S202, for each cloud account, a corresponding storage area is established in the server, and the storage area stores user information corresponding to the cloud account, data that has been backed up, and the like.

For example, the pre-stored information refers to the previously backed up communication information, and the step S102 includes the following sub-steps:

S2021. The communication information is extracted from the synchronization request, where the communication information may be address book information or communication record information.

S2022: compare the communication information with the communication information that the account has backed up;

S2023, generating a matching degree according to the comparison result.

In the step S203, if the matching degree is greater than the predetermined value, it is determined that the cloud account is logged in on the predetermined terminal. The predetermined terminal may be a mobile phone or a plurality of mobile phones and a PAD. The step S103 specifically includes: comparing the matching degree with a threshold; if the matching degree is greater than the threshold, determining that the cloud account is logged in at a predetermined terminal; if the matching degree is less than the threshold, determining The cloud account is not logged in at the predetermined terminal. The following is an example.

In the step S204, if the cloud account is logged in on the predetermined terminal, the corresponding synchronization data is sent to the corresponding terminal according to the synchronization request in step S201.

In this step S205, if the cloud account does not log in on the predetermined terminal, security verification is required. The security verification request may be a request to send another feature information for obtaining the login of the cloud account. The security verification request may also send a verification code acquisition request to the terminal, and simultaneously send a verification code to the pre-stored mobile phone number.

In this step S206, for example, the security verification response may include a dynamic verification code, or may have another feature information different from the feature information in step S201. For example, when the feature information in step S201 is the communication record information, the security response in this step carries the address book information or the SIM card information and the physical address information. When the feature information in step S201 is address book information, the communication record information or SIM card information and physical address information should be carried in this step.

If they are the same, the verification is successful, if not, then The verification of the manual failed. For example, the verification code sent by the server to the predetermined mobile phone number is 20123, and the verification code received in the security verification response from the terminal is also 20123, indicating that the verification is successful.

Case 2: If the request for acquiring another feature information of the terminal sent in the step S205 is performed, the feature information in the security verification response is compared with the pre-stored information, and if the matching degree exceeds a predetermined value, the security is indicated. The verification is successful. If the match is lower than the predetermined value, the security verification fails.

In this step S208, if the verification in step S207 is successful, indicating that the user sends the synchronization request, the corresponding synchronization data is sent to the terminal according to the synchronization request in step S201. If the verification fails in step S207, it indicates that the synchronization request is not sent by the user, and the cloud account password may be leaked, so that the synchronization data is prohibited from being sent, and the password leakage prompt information is sent to the predetermined mobile phone or mailbox.

As shown in the above, the present invention receives the synchronization request sent by the terminal, where the synchronization request carries the cloud account information and the feature information of the terminal; and based on the pre-stored information, acquires the matching degree of the feature information; Whether the cloud account is logged in at the predetermined terminal; when the cloud account is logged in at the predetermined terminal, the synchronization data is sent to the terminal according to the synchronization request, thereby completing the synchronization of the data from the server to the terminal, thereby preventing the cloud account and password from being leaked.
