update the database file to correspond to the security data without the additional file, and
return the update authority when the update is completed.
4 . The electronic device of claim 1 , wherein the processor is further configured to perform a third security data processing process when the first security data processing process or the second security data processing process fails.
5 . The electronic device of claim 4 , wherein the processor is further configured to perform the third security data processing process to:
add a frame corresponding to the security data to the additional file,
produce a thread for processing the security data,
update a database file to correspond to the security data based on a life cycle configured in the security data, and
invalidate the additional file corresponding to the security data when the update is completed.
6 . The electronic device of claim 5 , wherein the processor is further configured to:
when the life cycle is configured in the security data, wait for the update by the life cycle, determine whether an update condition of the additional file is satisfied after the life cycle has elapsed, acquire an update authority for the database file to attempt to update the database file to correspond to the security data when the update condition is satisfied, and
when the life cycle is not configured in the security data, determine whether the update condition of the additional file is satisfied, and acquire the update authority for the database file to attempt to update the database file to correspond to the security data when the update condition is not satisfied.
7 . The electronic device of claim 6 , wherein the processor is further configured to:
determine whether a configured condition is satisfied when the attempted update fails,
wait for the update until acquiring the update authority when the configured condition is satisfied, and
acquire the update authority to update the database file to correspond to the security data.
8 . The electronic device of claim 5 , wherein the processor is further configured to invalidate the additional file by truncating a size of the additional file corresponding to the security data or by overwriting a frame of the additional file.
9 . The electronic device of claim 8 , wherein the processor is further configured to perform one of an operation of truncating the size of the additional file based on a storage space of the memory or an operation of overwriting the frame of the additional file.
10 . The electronic device of claim 9 , wherein the processor is further configured to:
perform the overwriting operation when the storage space of the memory is equal to or greater than a predetermined size, and
perform the truncating operation when the storage space is less than the predetermined size.
11 . The electronic device of claim 1 , wherein the processor is further configured to:
determine whether security attributes are configured in a storage for a database file when the database file stored in the memory is opened, and
apply the security attributes to the entire opened database file when the security attributes are configured in the storage.
12 . The electronic device of claim 11 , wherein the processor is further configured to:
determine whether the security attributes are configured in the memory when the security attributes are not configured in the storage; and
read a value configured in the memory to perform update corresponding to the security data when the security attributes are configured in the memory,
wherein the security attributes of the storage have a characteristic of being maintained until an application corresponding to the database file is deleted, and
wherein the security attributes of the memory have a characteristic of being maintained to correspond to a connection of the database file.
13 . The electronic device of claim 12 , wherein the security attributes are configured in at least one of the entire database file and a table or column of the database file.
14 . An operation method of an electronic device, the operation method comprising:
receiving a request for updating security data in which security attributes are configured in application data;
identifying a state of an additional file corresponding to the security data;
determining a first security data processing process when the identified state of the additional file is invalid, and determining a second security data processing process when the identified state of the additional file is valid; and
updating the security data according to the determined security data processing process.
15 . The method of claim 14 , wherein the first security data processing process comprises:
acquiring an update authority for a database file stored in a memory;
updating the database file to correspond to the security data without the additional file; and
returning the update authority when the update is completed.
16 . The method of claim 14 , wherein the second security data processing process comprises:
determining whether a page structure of a database file stored in a memory is changed;
determining whether a page corresponding to the security data exists in the additional file when the page structure is not changed;
acquiring an update authority of the database file when the page corresponding to the security data does not exist in the additional file;
updating the database file to correspond to the security data without the additional file; and
returning the update authority when the update is completed.
17 . The method of claim 14 , further comprising:
performing a third security data processing process when the first security data processing process or the second security data processing process fails.
18 . The method of claim 17 , wherein the third security data processing process comprises:
adding a frame corresponding to the security data to the additional file;
producing a thread for processing the security data;
updating a database file to correspond to the security data based on a life cycle configured in the security data; and
invalidating the additional file corresponding to the security data when the update is completed.
19 . The method of claim 18 , further comprising:
when the life cycle is configured in the security data,
waiting for an update by the life cycle,
determining whether an update condition of the additional file is satisfied after the life cycle has elapsed, and
acquiring an update authority for the database file to attempt to update the database file to correspond to the security data when the update condition is satisfied; and
when the life cycle is not configured in the security data,
determining whether the update condition of the additional file is satisfied, and
acquiring the update authority for the database file to attempt to update the database file to correspond to the security data when the update condition is not satisfied.
20 . The method of claim 19 , further comprising:
determining whether a configured condition is satisfied when the attempted update fails;
waiting for the update until acquiring the update authority when the configured condition is satisfied; and
acquiring the update authority to update the database file to correspond to the security data.
