The following describes an embodiment of the present invention by taking the above-mentioned predetermined file as a picture or a video file as an example:

In this embodiment, the encryption operation is performed during the photographing or imaging process, and the encryption is performed by red. The complex gestures implemented by the outside sensor are completed. In addition, four small infrared sensors are built in the terminal, and the image is encrypted by a palm-shaped 8-word method. The generated 8-word graphic is converted into a hexadecimal digital signal by analog-to-digital conversion as the first two digits of the generated picture or video file name and the corresponding suffix name (may also be used as the suffix name of the picture or video file). Moreover, in this embodiment, the generated picture or video is generally invisible in the library because of the encryption process, and only the corresponding user knows the existence of the picture, and the user can proceed before the user enters the library to open the encrypted picture. The corresponding finger operation (ie, the decryption operation), the operation is received, and converted into a corresponding digital signal, and then matched with the secret used by the saved picture. If they are consistent, the first two bytes of the file name are temporarily removed, and the operation is resumed. The original file suffix name, the correct naming file for the user to consult, if the review is completed, exit the gallery interface, then immediately encrypt again. Wherein, when the decryption operation is performed, the reverse direction gesture action can be used for decryption, and after a series of processing, it becomes a string of digital codes, and the digital code can be compared with the encryption secret after the reverse order processing, and the security is performed. higher.

In this embodiment, the front panel of the smart terminal can have four infrared sensors built in, as shown in FIG. 3 above, the four infrared sensors need to be placed at the four corners of the terminal (assuming that the infrared sensor in the upper left corner is numbered 101, upper right The number of the infrared sensor of the corner is 102, the number of the infrared sensor in the lower left corner is 103, and the number of the infrared sensor in the lower right corner is 104), and the palm (or finger) is sequentially drawn in the order of 101 to 102 to 103 to 104 to 101. According to the size and time of the infrared light return value, a figure drawn by the palm is generated as shown in FIG. 4 .

The following describes the principle of the infrared gesture: the four infrared sensors receive the reflected infrared light value and the corresponding time value, and recover the graphic drawn by the palm according to the maximum order of the received infrared light. It should be noted that the number and position of the infrared sensors in the above terminal can be flexibly set, and the image swiped by the palm can also be freely defined (for example, a rectangle is drawn). Therefore, for a single use, the palm is crossed. The image can be unique.

The following describes the photo encryption process in conjunction with a specific embodiment:

An encryption method is provided in this embodiment. As shown in FIG. 5, FIG. 5 is a schematic diagram of a process of encrypting a photographing process. Among them, the photo process encryption operation mainly involves five modules, namely an image sensor module, a gesture sensor, an A/D conversion module, an encryption processing module, and a storage module. The specific process is as follows:

Step 1: Turn on the camera to enter the framing mode, and the gesture sensor and image sensor enter the working mode respectively. The user operates his own gestures directly above the screen of the mobile phone, such as drawing a character, drawing a square, and the infrared gesture sensor recovers the gesture pattern according to the time of the strongest infrared light reflected from the palm;

Step 2: The finger clicks on the camera button, and the image sensor starts to receive the different intensity light of the received scene and converts it into an analog electrical signal;

The third step: analog image electrical signal, the simulated gesture signal enters the A/D conversion module at the same time, and the A/D conversion module mainly converts the analog signal into a digital signal that is convenient for the central processor to process;

The fourth step: the image digital signal and the gesture digital signal respectively enter the encryption processing module. Here, the encryption processing module includes several aspects of work, firstly, the digital signal is received for optimization, amplification, correction, etc., and is converted into a complex digital operation. The picture signal that can be displayed on the display; secondly: the gesture digital signal is converted into a specific code, and the first two letters of the image file are named or the image file suffix name, and the image encrypted by the gesture is saved in the memory, but Since it is encrypted, the same gesture is not used to decrypt the person and the picture will not be visible.

FIG. 6 is an encryption flowchart of a photographing process according to an embodiment of the present invention. As shown in FIG. 6, the method includes the following steps:

Step S600: Start.

Step S601: For the camera function, the user turns on the terminal device camera to enter the framing mode; for the camera function, the user directly enters the recording interface.

Step S602: For the camera function, the framing mode system automatically gives a certain waiting time, during which the gesture sensor is in a working state, monitoring whether there is a gesture action signal, if any Directly entering the gesture signal receiving step, go to step S603; if the gesture signal is not received within the prescribed time period, directly enter the photographing step S604, and for the camera function, the gesture sensor can work synchronously with the image sensor.

Step S603: recovering the received gesture analog signal by the infrared sensor, and then performing specific analog-to-digital conversion, and then proceeds to the next encryption processing module, and proceeds to step S606.

Step S604: If the user does not find any gesture action, directly take a photo or video recording.

Step S605: The picture analog signal will be received, and after analog-to-digital conversion, a series of digital operations will become a specific digital signal.

Step S606: Then use the gesture digital signal to perform the encryption operation. The typical operation of the encryption operation here is: the digital signal output by the gesture action is converted into a hexadecimal number, and then the hexadecimal number is used as the first two digits of the generated image file name and corresponding The suffix name, the algorithm here can also be customized.

Step S607: After the encryption, the picture enters the memory saving, and the process ends.

It should be noted that the above gestures are not only applied to pictures, but also can be applied in video, short message, voice call and all mobile phone function operations.

Encrypted graphics users can also be customized, complex and simple, and give users maximum operational privileges.

Because the process is very fast, the camera will reserve a certain waiting time in the camera view interface. When the waiting time expires, if the gesture has not been received, the camera is considered not to be encrypted. For video recording, since the recording process takes a long time, input gestures and recorded video can be performed simultaneously.

The following describes the process of camera decryption in conjunction with a specific embodiment:

In this embodiment, a picture decryption method is provided. As shown in FIG. 7, FIG. 7 is a block diagram of a picture decryption process according to an embodiment of the present invention.

The image decryption consists of 6 parts, which are open the gallery, draw gestures, gestures The module, the A/D conversion module, the picture decryption module, and the picture in the last memory are displayed. First, the user enters the terminal memory display interface, and then controls the gesture, the gesture sensor immediately accepts the reflected infrared light, and then the original image is restored according to the chronological order and the intensity of the infrared light, and the A/D conversion module will receive the simulation. The signal is converted into a corresponding digital signal. The image decryption module mainly analyzes and processes the first two digits of the image file, and then compares with the acquired gesture signal value. If it matches, the image name is changed, the image is visible, and the image can be edited. Do not display, that is, users are not allowed to view related content.

FIG. 8 is a flowchart of decryption according to an embodiment of the present invention. As shown in FIG. 8, the process includes the following steps:

Step S800, starting;

Step S801, the user opens the picture memory;

Step S802: The user draws a gesture in the air;

Step S803: the gesture sensor converts the received gesture signal into an electrical signal, and then simulates a corresponding gesture motion according to the electrical signal, and then converts the gesture motion into a series of digital signals after being converted by A\D;

Step S804: Receive the gesture digital signal, rearrange it in reverse order, and then change to a hexadecimal number. The generated hexadecimal number is directly checked with the first two letters and the file suffix name of all the image file names that have been encrypted. ;

Step S805, if the match, the picture can be displayed and can be operated. If it does not match, the picture is not displayed, and is invisible;

In step S806, the process ends.

It should be noted that if the user opens the encrypted picture and then does not delete it after viewing the encrypted picture, the memory is turned off momentarily, and the picture continues to remain in the encryption mode.

9 is a schematic diagram of a sequence of encryption and decryption gestures according to an embodiment of the present invention, wherein the numbers in FIG. 9 represent the order of sliding, and the left diagram in FIG. 9 may be an encrypted schematic diagram, on the right side. The figure may be a schematic diagram of decryption. Due to the reverse reverse order calculation method adopted by the algorithm processor in the embodiment of the present invention, before the user browses the picture or video, the input gesture must be opposite to the order of encryption, if decrypted and encrypted. If the gestures are exactly the same, the match fails.

The solution in the embodiment of the present invention is mainly applied to photo-encryption: the specific process is: the user opens the photographing function, and then controls the drawing of the specific gesture, and then can start taking the photograph, the photographing is completed, the image is encrypted, and is not stored in the library and the like. display. If the user wants to view the image, open the gallery and then draw the same gesture in the air, you can open the image for browsing, or various corresponding operations.

The method used in this embodiment can also be applied to more scenarios, in addition to the above-mentioned photo process encryption, recording video process encryption, and a short message writing interface, and the call process can be applied, for example, when the user wants to call some people. As an encrypted phone, if you don't want other people to answer, you can set the gesture password in the contact. When the contact calls, the interface does not display the name of the person. Other users cannot access it. Only the specific user picks up the phone and controls the picture. A specific gesture is required to answer the call.
