Example two
Based on a more preferable scheme of the file processing method provided by the first embodiment, please refer to fig. 2, which shows a method flowchart of the file processing method provided by the second embodiment of the present invention. The file processing method can be used for encrypting or hiding files in a terminal, the files can be documents, pictures, videos or audios and the like, and the terminal can be a mobile terminal such as a smart phone, a tablet computer, an electronic book reader or a digital camera. Taking an example of encrypting a shot photo in a smart phone including an image acquisition unit, the file processing method may include:
step 202, the terminal acquires an identifier of an application program at the stack top of a current operating system, and detects whether the acquired identifier of the application program is matched with an identifier of a specified application program;
specifically, when the file to be processed is a photograph just taken, the specified application program may be a camera program in a smartphone. In the smart phone, an application program at the top of a current operating system stack is usually displayed on the top layer of a screen of the smart phone, so that a terminal can start a stack top scanning thread for monitoring the change of the top of the operating system stack, when the application program at the top of the stack is monitored to be changed, an identifier of the application program at the top of the stack, such as the name of the application program, is obtained, whether the name of the application program is matched with the name of a camera program in the smart phone is detected, if the name of the application program is detected to be matched with the name of the camera program in the smart phone, it is indicated that the camera program in the smart phone is in an open state, and at the moment, if a newly generated picture type file is monitored, the newly generated picture type file can be determined to be a photo to be processed.
Step 204, if the obtained identifier of the application program is matched with the identifier of the specified application program, the terminal determines an effective directory;
for example, a user may manually change a storage directory of a newly-taken photo, and monitoring file events in all storage directories in the smart phone wastes too many resources and is not easy to implement. Therefore, before monitoring the picture file corresponding to the newly-taken picture, it is necessary to determine the active directory that the camera program may use to store the newly-taken picture, and only monitor the active directory for the file event. Specifically, the terminal may determine a storage directory meeting a second predetermined condition under the current operating system as an active directory, where the second predetermined condition may be one or a combination of two or more of the following three conditions:
1) the storage directory is in a non-hidden state;
since the camera program does not usually hide the storage directory, the terminal may listen only to the non-hidden storage directory.
2) The storage directory is located at a level less than a predetermined level;
in general, the number of hierarchies is not too high whether the default storage directory of the camera program or the storage directory manually set by the user, so the terminal may preset a predetermined hierarchy, for example, set the predetermined hierarchy to 5, and listen to the directory with the hierarchy number less than 5 as an active directory that the camera program may use to store a newly taken picture, while the storage directory with the hierarchy number greater than or equal to 5 is ignored.
3) The storage directory is a directory that the specified application program was last stored.
The directory storing the newly taken picture may not be changed between the last time the camera program takes the picture and the current time the camera program takes the picture, so that the terminal records the storage directory storing the newly taken picture in the camera program when the terminal last listens for a file event, and determines the recorded directory as an effective directory when the terminal this time listens.
By determining the effective directory, the terminal can avoid consuming too many resources while expanding the monitoring range as much as possible, and the terminal performance is improved.
Step 206, the terminal monitors each file event corresponding to the file in the active directory, filters the monitored file events, and adds the filtered file events into the event sequence corresponding to the file;
many types of files may be contained in the effective directory, not all types of files meet the requirements, and the event sequence corresponding to the file is acquired only when the type of the file is consistent with that of the file generated by the specified application program.
For example, in the second embodiment of the present invention, a photo newly taken by a camera program must be in a picture format, and a terminal may detect a format type of a file corresponding to a monitored file event, and if the file is not in a picture format such as BMP (Bitmap), JPEG (joint photographic experts group), or GIF (graphics interchange format), an event sequence corresponding to the file is not acquired.
In addition, there may be many file events corresponding to one file, and not all file events may be used to detect whether to process the file, and even if all the monitored file events are added to the event sequence, the terminal needs to select a part of the file events to detect in the subsequent process of detecting whether to process the file. If all file events are added into the event sequence, the file events which are not suitable for detection occupy too much memory resources, and a certain processing resource is additionally consumed in the subsequent process of detecting whether the file can be processed according to the file events in the event sequence because the file events which are not suitable for detection are contained in the event sequence. In order to reduce the consumption of memory and processing resources and improve the system performance, the type of the file event monitored by the terminal needs to be limited.
Specifically, for example, in the second embodiment of the present invention, the criterion for determining whether to process the photo generated by the camera program is that the photo is a newly taken photo, and for a newly taken photo, the generation process of a picture file is necessarily accompanied, and the generation process of the picture file corresponding to the photo mainly includes the following types of file events: create event Create, Open event Open, Modify event Modify, Close event Close, and Move To specified directory event Move To. In addition, the system may generate some events unrelated to the picture file generation process, such as Access event Access generated when the file is accessed, Move _ From specified directory event, negligible event generated when the monitoring item itself is terminated or removed, overflow event generated when the system is busy to cause file event overflow, directory related event generated when the directory is created or deleted, and the like. When monitoring file events, the terminal can be preset to monitor only 5 types of file events related to the generation process of the picture file, and the other types of file events are ignored.
Secondly, even the 5 types of file events may include situations that are not suitable for detecting whether to process the file, and further filtering the monitored predetermined type of file event is needed, for example, the terminal may monitor the predetermined type of file event corresponding to the file and detect whether to perform the predetermined processing on the file corresponding to the monitored predetermined type of file event currently; and if the detection result is that the monitored file corresponding to the file event of the preset type is not subjected to preset processing currently, adding the file event into the event sequence corresponding to the file.
In the second embodiment of the present invention, the predetermined processing performed by the terminal on the photo generated by taking the photo may include encrypting or hiding the photo. However, in the process of encrypting or hiding the photo, operations such as opening, modifying or closing the file may be involved, and file events such as an opening event, a modifying event or a closing event may be generated correspondingly.
Specifically, the terminal may record an identifier of a file undergoing a predetermined process, for example, a name or an ID (IDentity) of a photo, compare the name or the ID of the file corresponding to the file event with the name or the ID of the recorded file when the file event is monitored, and filter the file event if the name or the ID of the file corresponding to the file event is matched with the name or the ID of the recorded file.
Step 208, the terminal detects whether the file event in the event sequence meets a first predetermined condition;
after obtaining the filtered event sequence, the terminal may detect whether a file event in the event sequence meets a first predetermined condition, where the first predetermined condition may include one of the following two conditions:
1) the event sequence comprises a move-in appointed directory event;
the specified directory may be an active directory currently monitored by the terminal, and before the application program moves a file from outside the active directory into the active directory currently monitored, the operation processes of creating, opening, modifying, closing and the like of the file are usually completed under the original directory of the file, so that when an event sequence of a file contains an event of moving in the specified directory, other types of file events are often not included, and therefore, when the event sequence contains an event of moving in the specified directory, the file corresponding to the event sequence can be considered to be subjected to predetermined processing.
2) The event sequence comprises a creation event and at least one modification event, and the number of opening events and closing events contained in the event sequence is the same;
if the event sequence of a file contains a creation event, the file is indicated as a newly generated file, and if the event sequence only contains the creation event but does not contain a modification event, the newly created file is indicated as an empty file without being modified, and predetermined processing is not required. Therefore, the terminal may detect whether at least one modification event is further included in the event sequence when the creation event is included in the event sequence, and if so, determine that the file is not an empty file.
In addition, modifying a file requires opening and closing the file, and accordingly, an opening event and a closing event are necessarily generated, and when a file is in an open state, the file may not be modified, or some specific processing cannot be performed on the file in the open state, for example, the file in the open state cannot be encrypted. Therefore, the terminal needs to detect whether the file is in a closed state, specifically, the terminal may detect whether an open event and a close event in an event sequence corresponding to the file occur in pairs, for example, whether the numbers of the open event and the close event included in the event sequence are the same, and if the numbers are the same, the terminal detects that the file is in the closed state. For a newly created file, the terminal will determine it as a pending file only if the file is not an empty file and the file is in a closed state.
The method comprises the steps of detecting a combination of multiple types of file events, directly determining a file to be processed when detecting that an event sequence corresponding to the file contains a move-in appointed directory event, further detecting an opening event, a closing event and a modification event in the event sequence when detecting that the event sequence corresponding to the file contains a creation event, determining the file event as the file to be processed if detecting that the opening event and the closing event occur in pairs and at least one modification event is contained, and fully considering the specific situation in the file generating process, thereby effectively detecting whether the file can be processed or not and improving the detection accuracy.
Step 210, if the file event in the event sequence meets the first predetermined condition, the terminal performs predetermined processing on the file.
If the terminal detects that the file meets the processing condition through the file event in the event sequence, the file can be subjected to predetermined processing such as encryption or hiding.
Taking the example of encrypting a newly shot photo in a smart phone, in practical applications, the specific process of monitoring a file event and detecting whether to process the photo according to the monitored file event can be implemented as follows:
the smart phone presets the type of the file event monitored, and in the embodiment of the present invention, the preset type of the file event includes a Create event Create, an Open event Open, a Modify event Modify, a Close event Close, and a Move-in specified directory event Move _ To. It should be noted that the Close event Close can be divided into two categories: events Close _ Write that closes a writeable file or directory, or Close _ Write that closes a read-only file or directory, both of which can be classified as Close events.
Specifically, when the smart phone monitors a file event in an active directory, it first sequentially detects whether the monitored file event is a file event unrelated to the picture generation process, such as a negligible event, an overflow event, or a directory-related event.
If the file event is not a file event which is irrelevant to the picture generation process, such as an ignorable event, an overflow event or a directory-related event, whether a file corresponding to the file event is encrypted is further detected.
If the file event is not encrypted currently, the smart phone performs the following processing according to the specific type of the file event:
if the file event is a creation event, further detecting whether a file created by the file event is in a picture format, if so, correspondingly creating an information monitoring item for the file, setting an identifier of the creation event in the information monitoring item, and adding the information monitoring item into a monitoring item list;
if the file event is a moved-in appointed directory event, further detecting whether a file corresponding to the moved-in appointed directory event is in a picture format, if so, correspondingly creating an information monitoring item for the file, setting an identifier of the moved-in appointed directory event in the information monitoring item, and adding the information monitoring item into a monitoring item list;
if the file event is an opening event, searching an information monitoring item of a file corresponding to the opening event in a monitoring item list, and adding 1 to the count of the opening event;
if the file event is a closing event, searching an information monitoring item of a file corresponding to the closing event in a monitoring item list, and subtracting 1 from the count of the opening event;
if the file event is a modification event, searching the information monitoring item of the file corresponding to the modification event in the monitoring item list, and adding 1 to the count of the modification event.
While the above process is executed, the smart phone also selects a file to be encrypted according to the monitoring item list, and the specific selection methods may include the following two methods:
1) traversing the monitoring item list, and selecting files corresponding to the information monitoring items which comprise the identifiers of the created events, the count of the opened events is 0, and the count of the modified events is at least 1 as encrypted files;
2) and traversing the monitoring item list, and selecting files corresponding to the information monitoring items containing the identifiers of the moved-in appointed directory events as files to be encrypted.
And the smart phone encrypts the selected encrypted file.
It should be noted that, with the method provided in the second embodiment of the present invention, after a predetermined type of file event in an active directory is monitored, the monitored file event is distinguished by taking a file as an object, and an event sequence is respectively obtained for each file, so that respective detection of multiple files can be realized, mutual interference can be effectively avoided when different files in the same file directory are detected, and in addition, the method for respectively detecting multiple files can also simultaneously support the operation of multiple similar applications.
In summary, in the file processing method provided in the second embodiment of the present invention, the event sequence corresponding to the file is obtained by monitoring the file event corresponding to the file of the specific type, and the file is subjected to the predetermined processing when it is detected that the file event in the event sequence satisfies the predetermined condition, so that the problems that the user needs to manually complete the processing process in the prior art, thereby wasting the user time and consuming a large amount of electric quantity of the terminal are solved, and the purposes of saving the processing time and the electric quantity of the terminal and improving the endurance performance of the terminal are achieved; secondly, in the file processing method provided by the second embodiment of the present invention, by monitoring the file events of the predetermined type, filtering the monitored file events of the predetermined type, and only adding the file events suitable for detection into the event sequence, the purposes of reducing memory consumption and improving system performance are achieved; in addition, in the file processing method provided by the second embodiment of the present invention, the valid directories are determined in all the storage directories under the system, and the files in the valid directories are monitored, so that the purpose of avoiding consuming too many resources and improving the terminal performance while expanding the monitoring range as much as possible is achieved; in addition, the file processing method provided by the second embodiment of the present invention monitors files as objects, and obtains event sequences for each file, so as to be able to implement respective detection for multiple files, effectively avoid mutual interference when detecting different files in the same file directory, and provide support for the operation of multiple similar applications at the same time; finally, the file processing method provided by the second embodiment of the present invention fully considers the specific situation of file operation by detecting the combination of multiple types of file events, and can effectively detect whether the corresponding file can be processed, thereby improving the detection accuracy.
