1 shows a flow 100 of one embodiment of a file processing method for an electronic device of the present application having a file management function.

Flow 100 describes the processing steps when locking a file. Specifically as shown in Figure 1. It is shown that the file processing method for an electronic device of this embodiment includes the following steps:

Step 101: Acquire an operation of the electronic device by the user in each time period in the predetermined at least two time periods.

In the present embodiment, an electronic device (i.e., a terminal device such as a mobile phone having a file management function) can locally acquire an operation of the user for each time period. The above operations may include: inputting a set of passwords, artificially caused state changes of the electronic device hardware (eg, volume addition, subtraction, shutter, etc.), or other conceivable operations (eg, screen combo three times), and the like. The number of the predetermined time periods described above may be preset by the user, and after all the time periods are over, the step 101 ends; or the end of the step may be determined by the user having no operation for a predetermined length of time (for example, 5 seconds).

Step 102: Generate operation key data corresponding to each operation according to the obtained operation, and assign a permission level to each of the operations, and each permission level is incremented step by step according to the execution order of the corresponding operation.

In this embodiment, generating the operation key data corresponding to each of the operations according to the obtained operation may include: the electronic device may generate, for each operation acquired, if the operation is performed first, generate the operation Corresponding operation key data, otherwise the operation is combined with all operations performed before the operation in an execution order to generate an operation key data. Exemplarily, for the first operation, a binary data may be generated according to the first operation as the operation key data corresponding to the first operation; for other operations, the binary data corresponding to the operation may be performed on the operation. The binary data corresponding to all previous operations are combined in the order of execution as the operation key data corresponding to the operation. On this basis, the privilege level assigned to the operation can be expressed as the privilege level of the operation set combined with the operations performed before the operation in the execution order. For example, the user performs three operations on the electronic device in three time periods, so the permission level assigned to the first operation is one level, the permission level assigned to the second operation is level two, and so on. The secondary permission level can be expressed as the first operation plus the permission level of the second operation. An operation key data is generated by combining operations and all operations performed before the operation in an execution order, so that one operation key data can be used to identify a plurality of sequential operations, thereby enabling file processing of the present embodiment. The method of document protection is more diverse.

Step 103: Bind each of the foregoing operation key data to a permission level corresponding to the corresponding operation.

In this embodiment, the electronic device may perform binding by associating the operation key data with the permission level. After binding, when unlocked later, the current user's own permission level can be obtained according to the matched operation key data.

Step 104: Hide the to-be-locked file associated with the permission level of each of the foregoing operation key data bindings.

In this embodiment, the to-be-locked file and its associated permission level are specified by the user. After the user sets the above operation, the electronic device hides the file associated with the permission level corresponding to the operation. .

In some optional implementations of this embodiment, before the hiding of the to-be-locked file associated with the permission level of each of the foregoing operation key data bindings, the method may further include: displaying for the user to select to be added. The file is locked and the interface of the permission level of the file to be locked is specified; the permission level to be locked by the user and the permission level of the file to be locked set by the user are associated and saved. The foregoing processing may be performed after the user sets the operation, or before the user sets the operation, and the embodiment does not limit the sequence.

In some optional implementation manners of this embodiment, the file processing method for an electronic device of the present application may further include: displaying an interaction interface for specifying an operation name for an operation performed by the user; receiving the operation name, and The above operation name is associated with the operation key data corresponding to the above operation. By adding the operation name attribute and associating with the operation key data, when the electronic device cannot recognize the operation or the user forgets the unlocking operation, the file can be unlocked and displayed by the operation name instead of the operation key data. Thereby, the fault tolerance of the file processing method for an electronic device of the present embodiment is enhanced.
