5. The method according to claim 2, further comprising:

resetting a confidential-data-or-not flag of the non-confidential data, and setting the confidential-data-or-not flag of the confidential data, wherein the confidential-data-or-not flag is used for indicating whether the data is confidential data or non-confidential data.

6. The method according to claim 5, wherein the process of obtaining and processing the non-confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is non-confidential data; and

obtaining and processing the data if the data is non-confidential data.

7. The method according to claim 5, wherein the process of obtaining and processing the confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is confidential data; and

obtaining and processing the data if the data is confidential data.

13. The method according to claim 3, further comprising:

resetting a confidential-data-or-not flag of the non-confidential data, and setting the confidential-data-or-not flag of the confidential data, wherein the confidential-data-or-not flag is used for indicating whether the data is confidential data or non-confidential data.

14. The method according to claim 13, wherein the process of obtaining and processing the non-confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is non-confidential data; and

obtaining and processing the data if the data is non-confidential data.

15. The method according to claim 13, wherein the process of obtaining and processing the confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is confidential data; and

obtaining and processing the data if the data is confidential data.

16. The method according to claim 4, further comprising:

resetting a confidential-data-or-not flag of the non-confidential data, and setting the confidential-data-or-not flag of the confidential data, wherein the confidential-data-or-not flag is used for indicating whether the data is confidential data or non-confidential data.

17. The method according to claim 16, wherein the process of obtaining and processing the non-confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is non-confidential data; and

obtaining and processing the data if the data is non-confidential data.

18. The method according to claim 16, wherein the process of obtaining and processing the confidential data of every service comprises:

determining, according to the confidential-data-or-not flag of each data of the service, whether the data of the service is confidential data; and

obtaining and processing the data if the data is confidential data.
