It should be noted that, the terminal device obtains the first pixel data corresponding to the original photo generated when the user takes a picture through steps 305 and 306, and in practical applications, the user may also select to encrypt the existing local photo, so that the user sends a second instruction to the terminal device to instruct the terminal device to encrypt the locally stored original photo, and after receiving the second instruction, the terminal device obtains the first pixel data corresponding to the original photo from the local database. Therefore, the specific manner of obtaining the first pixel data is not limited herein.
In addition, the terminal device performs format processing on the first pixel data and the temporary data to obtain a native photo and a preview photo, where the format of the native photo and the preview photo may be jpeg, bmp, jpg, or the like, and the specific generation format is not limited here.
307. The terminal equipment executes other steps;
and after the terminal equipment receives the instruction that the user confirms not to start the encryption function, executing a normal photographing process.
308. The terminal equipment encrypts the original photo according to the secret data and the first pixel data to obtain an encrypted photo;
after the terminal device generates the first pixel data, the secret data and the first pixel data are operated according to a preset encryption algorithm to obtain a second pixel set, the terminal device performs format processing on the second pixel set to obtain an encrypted photo, and meanwhile, the terminal device stores the generated second pixel data and the secret data in different positions of the terminal device, such as a folder, a disk or a storage medium, and the specific position is not limited here.
It should be noted that the second pixel data may be stored in the terminal device after being generated, or may be obtained in real time when the encrypted photograph is decrypted without being stored, and therefore, the specific details are not limited herein.
It can be understood that the content displayed by the encrypted original photo is different from the content displayed by the encrypted original photo, i.e. the user cannot see the content displayed by the original photo from the encrypted photo.
In practical application, there are various preset encryption algorithms. For example, the first pixel data and the secret data are sequentially subtracted or sequentially added by a round function, or the first pixel data is alternately used at the center, and the secret data is interleaved according to a predetermined sequence, so that a specific preset encryption algorithm is not limited here.
309. The terminal equipment receives a photo decryption request;
when a user wants to preview the encrypted original photo, the user clicks an application icon of the encrypted photo reference software to indicate the terminal device to run the software, the terminal device runs the encrypted photo reference software, and the user can enable the terminal device to receive a photo decryption request sent by the user through clicking the icon of the encrypted photo so as to decrypt the encrypted photo.
310. The terminal equipment obtains second pixel data;
and after receiving a photo decryption request sent by a user, the terminal equipment generates second pixel data through the encrypted photo, wherein the second pixel data is a pixel set of the encrypted photo.
It should be noted that, in practical applications, the terminal device encrypts the original photo to obtain the second pixel data and generate the encrypted photo, the second pixel data and the secret data may be stored in different locations of a local database of the terminal device, and when the encrypted photo is decrypted, the second pixel data is directly obtained from the local database.

and after the terminal equipment obtains the second pixel data, the secret data and the second pixel data are operated according to a preset decryption algorithm to obtain temporary data, and the terminal equipment performs format processing on the temporary data to obtain a preview picture.
It will be appreciated that the preset encryption algorithm and the preset decryption algorithm are reversed. For example, the data 1358 is encrypted by an algorithm of adding 1 to each bit number to obtain encrypted data 2469, and when the encrypted data needs to be decrypted, the decryption algorithm is to subtract 1 from each bit number to obtain original data 1358.
312. The terminal equipment judges whether the state of the terminal equipment meets the preset condition of deleting the preview photo, and if so, the step 313 is executed; if not, go to step 314;
when the terminal equipment decrypts to obtain temporary data and a preview photo, detecting whether the state of the terminal equipment meets a preset condition for deleting the preview photo, and if so, executing a step 313; if not, go to step 314.
It should be noted that, in order to prevent the preview photo and the temporary data from being copied, the terminal device presets a condition for deleting the preview photo, and the condition may include: the terminal device detects that the decryption function is closed, the terminal device detects that the encrypted photo reference program is closed, the terminal device connects to an external storage device or the terminal device detects that the encrypted photo reference program is closed, and the like, and it is required to ensure that the encrypted photo reference program is in a preview state and the terminal device does not have access to the external storage device when the preview photo and the temporary data exist. Therefore, the specific condition for deleting the preview photo is not limited here.
In addition, as science and technology is continuously developed, more and more terminals are preset with a screen capture function, so that when a user utilizes an encrypted photo look-up program to decrypt and view a preview photo, the screen capture function of the terminal device is set to a use-prohibited state by the terminal device, so that when the user previews a primary photo, the display interface of the terminal device is currently captured, the generated screen capture picture can display the content displayed by the primary photo, and the privacy of the user is threatened.
313. The terminal equipment deletes the preview photo and the temporary data;
and the terminal equipment detects that the state of the terminal equipment meets the preset condition for deleting the preview photo, and simultaneously deletes the decrypted preview photo and the temporary data together to prevent the preview photo from being utilized by other people.
314. The terminal device performs other operations.
And when the terminal equipment detects that the state of the terminal equipment meets the preset condition of deleting the preview photo, the terminal equipment displays the preview photo.
