Exchangeable image file information simultaneously preserves.
In the present embodiment, if camera is secrecy type, need to exchangeable image file information into edlin, such as
Exchangeable image file information is modified as to the corresponding exchangeable image file information of camera of other unclassified types, reaches pseudo-
The purpose of dress, in this way, if the picture of the camera shooting of secrecy type when leaking, even if other people obtain the picture to leak can
Swap image fileinfo can only know that the camera is the camera of unclassified type, cannot judge that the camera is exactly crypto
The camera of type also would not learn the confidential information of the camera by analyzing exchangeable image file information in this way, improve
The safety of the camera of secrecy type.
Wherein, the exchangeable image file for the exchangeable image file information of secrecy type being compiled as to unclassified type is believed
Breath is there are many mode, such as can only change the model of exchangeable image file information, or modification model and some other
Important device-dependent information, or the exchangeable image file information of secrecy type is all replaced with other and has been listed
Unclassified type exchangeable image file information, in such manner, it is possible to prevent the confidential information of secrecy type from leaking.
Compared with prior art, the present embodiment obtains the exchangeable image file information of the picture of camera output in real time, when
Judge the camera for secrecy type when, can be edited by the exchangeable image file information of the secrecy type into edlin
It is pseudo- to be carried out to the exchangeable image file information of secrecy type for the exchangeable image file information of other unclassified types
Dress, in this way, even if the picture captured by the camera of secrecy type leaks, other people are in the commutative image for getting the picture to leak
After fileinfo, it can not know that the camera is that secrecy type carries therefore, it is possible to prevent the confidential information of secrecy type from leaking
High security.
In a preferred embodiment, as shown in figure 4, on the basis of the embodiment of above-mentioned Fig. 3, the reality of the information security
Now method further includes：
Step S201, when listening to write-in file in memory, obtains the type letter of the file under exposal model
Breath；
Step S202 then judges that the file exports for the camera when the type information is picture format information
Picture.
In the present embodiment, when camera enters exposal model, phase chance starts the associated snoop being mounted thereon and answers automatically
For monitoring whether camera exports picture.Preferably, camera is write by starting SD card file monitor to monitor in SD card in real time
The file entered, under exposal model, after camera shooting, captured picture can be written into SD card.
The file being written in SD card in order to prevent be not camera shooting picture and cause maloperation, camera is further to SD
The type for the file being written in card is judged, that is, obtains the type information of the file of write-in, when the type information is picture lattice
When the information of formula, it can be determined that this document is the picture of camera output.
In a preferred embodiment, as shown in figure 5, on the basis of the embodiment of above-mentioned Fig. 3, above-mentioned steps S102 packets
It includes：
Step S1021 reads the exchangeable image file information by scheduled mode and obtains the commutative figure
As the unit type in fileinfo；
Step S1022 judges whether the camera is secrecy type according to the unit type.
In the present embodiment, after getting the picture of camera output, picture can be read according to current operating system
Exchangeable image file information：It, can be by being in when current operating system is Android operation system "
ExifInterface classes under android.media.ExifInterface " packets read the exchangeable image file letter of picture
Breath, wherein although including Interface in ExifInterface titles, actually it is a class rather than one connects
Mouthful, the part of functions for belonging to media library is realized；When current operating system is iOS operating systems, imageIO can be utilized
Frame reads the exchangeable image file information of picture.
When reading the exchangeable image file information of picture, can know the manufacturer of camera, model, ISO, focal length,
Then the information such as aperture, white balance, shutter speed may determine that whether camera is secrecy type according to model.
The present embodiment can also preset blacklist on camera, and it is black that the model of the camera of all secrecy types is listed in this
In list, when whether judge camera is secrecy type, the model of the camera can be compared with the model on blacklist,
If there is identical, you can to judge the camera as secrecy type.
In a preferred embodiment, as shown in fig. 6, on the basis of the embodiment of above-mentioned Fig. 3, above-mentioned steps S103 packets
It includes：
Step S1031 obtains the corresponding exchangeable image file information of unclassified type；
