Detailed Description
The application simplifies the complicated encryption program into the operation of a single key or a few keys, and combines the detection of biological characteristics, and can provide different encryption modes for a user to select, so that the user can intuitively extract and encrypt the viewed screen contents (on-screen contents). Therefore, complex operation can be omitted, a user can conveniently select different modes to encrypt according to the requirement, and the data security is improved.
Fig. 1 is a block diagram of an electronic device according to an embodiment of the present application. Referring to fig. 1, the electronic device 100 of the present embodiment is, for example, a Smart phone (Smart phone) or a Personal Digital Assistant (PDA) phone, a Tablet PC (Tablet PC), a notebook PC, a Digital camera, a Digital video camera, a Digital audio recorder or any other electronic device, which includes a screen 110, at least one key 120 and a processor 130, and the functions thereof are described as follows.
The screen 110 may be a general Display such as a Liquid-Crystal Display (LCD), a plasma Display, a vacuum fluorescent Display, a Light-Emitting Diode (LED) Display, a Field Emission Display (FED), and/or other suitable type of Display. The screen 110 may also be a touch screen, for example, formed by integrating a resistive, capacitive or other touch sensing device with a liquid crystal display. In the present disclosure, any type of screen can be used to display the screen content of the electronic device 100.
The keys 120a, 120b, 120c may be physical keys configured on the electronic device 100 or virtual keys displayed on the screen 110 of the electronic device 100. In the present disclosure, the keys 120a, 120b, 120c are used to detect user operations to generate the trigger signal.
The Processor 130 is, for example, a Central Processing Unit (CPU), or other Programmable general purpose or special purpose Microprocessor (Microprocessor), Digital Signal Processor (DSP), Programmable controller, Application Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or other similar devices or combinations thereof. The processing unit 130 is coupled to the screen 110 and the keys 120, and executes an encryption function of the screen content according to the trigger signal generated by the keys 120. The following describes the detailed steps of the electronic device 100 executing the screen content encryption method by way of example.
Fig. 2 is a flowchart illustrating a screen content encryption method according to an embodiment of the present application. Referring to fig. 2, the method of the present embodiment is applied to the electronic device 100 of fig. 1, and the detailed steps of the screen content encryption method of the present application will be described below with reference to various elements in the electronic device 100.
First, in step S210, the electronic device 100 displays an arbitrary screen through the screen 110. Next, in step S220, the user operation is detected by the key 120 to generate a trigger signal. In step S230, the processor 130 encrypts the content displayed in the screen according to the trigger signal. The number of the keys 120 may be one or more. In one embodiment, the user touches different keys 120 to generate different trigger signals, and the processor 130 determines the encryption mode to be implemented by the user or the screen content (part or all of the content) to be encrypted according to the type of the received trigger signal, so as to encrypt the screen content.
Specifically, in an embodiment of the present application, when a user wants to encrypt the screen content displayed on the screen 110, the user can press or touch the key 120 or one of the keys 120 to generate the trigger signal. In one embodiment, the user presses the key 120 using a fixed encryption scheme and process. In another embodiment, the processor 130 may recognize whether the content displayed on the screen includes a file conforming to a predetermined format according to the trigger signal. The preset format may be an email, a short message, a text, a file, a photo, an image, an audio or a video, etc., but the present embodiment is not limited thereto, and different encryption methods and processes are performed. In another embodiment, the processor 130 identifies a currently executed function, software or program, such as a browser, a file program, an image browsing program, a video browsing program, a camera, etc., according to the trigger signal.
The above-mentioned identification result can be used to determine the file format after encryption or determine how to perform encryption processing. If the screen content conforms to the preset format, only the content can be encrypted and stored into a specific file; if the screen content does not conform to the preset format, the whole screen content can be extracted and classified into the file format of the picture, and the screen content is encrypted and stored into the picture.
For example, fig. 3A to 3C are schematic diagrams illustrating encrypted screen content according to an embodiment of the present application. Referring to fig. 3A, when the screen 110 displays the frame 32 of fig. 3A, the processor 130 identifies the content of the frame 32 to determine that the content is text, so as to encrypt the frame 32 and store the encrypted frame as a text file; alternatively, the processor 130 recognizes it as a file browsing software, and encrypts the file opened in the current frame 32. Referring to fig. 3B, when the screen 110 displays the frame 34 of fig. 3B, the processor 130 identifies the content of the frame 34 and determines that the content includes the movie 342, so that the movie 342 is encrypted and stored as a movie file; alternatively, the processor 130 recognizes it as a film browsing software, and encrypts the film file or film link opened in the current frame 32. Referring to fig. 3C, when the screen 110 displays the frame 36 of fig. 3C, since the frame 36 includes both the web page 362 and the text 364, the processor 130 cannot determine the file format to which the content of the frame 36 belongs, and thus the entire screen content is extracted and encrypted to be stored as the picture file; alternatively, the processor 130 identifies the frame 36 as a web page or the current program as a browser, and encrypts the web page address opened in the current frame 32, such as storing the web page address in a specific and encrypted folder, such as storing my favorite of the user through encryption.
In addition, when the processor 130 cannot determine the file format to which the screen content of the screen 110 belongs, in other embodiments, the user may select the file format (e.g., e-mail, text, file, photo, image, audio, video, etc.) to be stored by additionally opening a menu. It should be understood by those skilled in the art that the foregoing embodiments are illustrative only, and the present application is not limited thereto.
On the other hand, in the above embodiment, the encryption mode can be set by the user. For example, the encryption method may be to require the user to input a password and then perform encryption according to the input password. When the user wants to decrypt, the user only needs to input the previously input password to decrypt. The encryption method may also be to store the picture to be encrypted in a specific data folder, wherein the specific data folder needs to be entered with a specific password or in another secure manner, such as a specific gesture (gettrue) or a specific pattern (pattern). However, it should be understood by those skilled in the art that the above encryption manner is only an exemplary illustration, and the present application is not limited thereto.
In addition, in one embodiment, the present application can also identify the identity of the user and execute the encryption method set by the user accordingly. In the present application, the key 120 of the electronic device 100 is further provided with a biometric sensor (e.g., a fingerprint sensor, but the present application is not limited thereto) to identify different users by using the biometric characteristic and execute the encryption method set by the user. The keys 120 may be physical keys or may be virtual keys displayed on a touch screen with a biometric function. In general, the biometric characteristics need to be registered or stored in advance for comparison. After the registered biological characteristic data is prepared, when the key with the biological characteristic sensor senses the biological characteristics of the user, the registered biological characteristic data can be directly compared with the registered biological characteristic data to judge whether the registered biological characteristic data is consistent.
When any user wants to encrypt the screen content displayed on the screen 110, if the user presses or touches the key 120 with the biometric sensor, the key will sense the biometric characteristic of the user while generating the trigger signal, and compare the biometric characteristic with the pre-registered biometric characteristic data. If the biometric data matches the pre-registered biometric data, the screen content can be encrypted by using the encryption mode set by the user corresponding to the biometric data. Otherwise, if the biometric data is not consistent with the pre-registered biometric data, the screen content is encrypted or not encrypted in a preset mode, or no action is generated.
It should be noted that the biometric features of the above embodiments can be used to identify different users to choose the encryption method. For example, the screen content to be encrypted is stored in a folder corresponding to the user, the screen content is encrypted by using a specific password, or the screen content to be encrypted is encrypted and stored in a specific file format. The biometric feature can also be used directly for encryption, i.e. the biometric feature is used as a password for the encrypted screen content. However, it should be understood by those skilled in the art that the above-mentioned application of the biometric features is only illustrative and not limiting.
On the other hand, in another embodiment of the present application, the electronic device 100 may further include at least two keys for respectively corresponding to different encryption manners. For example, fig. 4 is a flowchart illustrating a screen content encryption method according to an embodiment of the present application. Referring to fig. 4, the method of the present embodiment is applied to the electronic device 100 of fig. 1, and the detailed steps of the screen content encryption method of the present application will be described below with reference to various elements in the electronic device 100.
In step S410, the electronic device 100 utilizes the first button 120a to detect the operation of the user to generate a first trigger signal, and the processor 130 encrypts the content displayed on the screen in a first manner accordingly. In step S420, the electronic device 100 utilizes the second button 120b to detect the user' S operation to generate a second trigger signal, and the processor 130 encrypts or does not encrypt the content displayed in the frame in a second manner according to the second trigger signal. The detection and encryption manners of the steps S410 and S420 are respectively the same as or similar to those of the steps S220 to S230 in the foregoing embodiment, and therefore, the description thereof is omitted.
Different from the foregoing embodiments, in the present embodiment, two keys are disposed on the electronic device 100 to respectively correspond to two different encryption manners, wherein both of the two keys may have an encryption function or only one of the two keys has an encryption function. For example, in one embodiment, the biometric sensing device can be selectively installed on one key, and another key directly corresponds to an encryption function. Therefore, when the user touches or presses the key with the biological sensing device, the corresponding encryption mode can be determined according to the sensed biological characteristic data. That is, the identity of the user is identified according to the sensed biometric data, so as to apply an encryption mode corresponding to the identified user. On the other hand, when the user touches another key, the screen content is directly encrypted by using the encryption mode corresponding to the key. In another embodiment, only one key corresponds to the encryption function, and the biometric sensing device is disposed on the key to extract the biometric characteristic of the user and determine the encryption mode accordingly. The other key is used for extracting the screen content without encryption. However, it should be understood by those skilled in the art that the above-mentioned keys and corresponding encryption manners are only exemplary, and the application is not limited thereto.
In another embodiment of the present application, when the electronic device 100 executes a specific application, the electronic device 100 may also encrypt the screen content displayed when the application is executed by the method described above. For example, when the user activates the photographing function of the electronic device 100, so that the electronic device 100 is in the photographing mode, the photograph taken by the electronic device 100 can be encrypted.
In detail, fig. 5 is a flowchart illustrating a method for encrypting screen content in a photographing mode according to an embodiment of the present application. Referring to fig. 5, the method of the present embodiment is applied to the electronic device 100 of fig. 1, and the detailed steps of the screen content encryption method of the present application will be described below with reference to various elements in the electronic device 100.
In step S510, the first shutter button 120a disposed on the screen 110 of the electronic device 100 is used to detect a user' S operation to generate a first trigger signal, and the processor 130 captures a first photo and encrypts the first photo accordingly. In step S520, the second trigger signal is generated by detecting the user' S operation with the second shutter button 120b disposed on the screen 110 of the electronic device 100, and the processor 130 takes the second photo accordingly and does not encrypt the second photo. The detection and encryption manners of the steps S510 and S520 are the same as or similar to those of the steps S410 and S420 in the foregoing embodiment, and therefore, the description thereof is omitted.
Unlike the previous embodiment, in the present embodiment, when the electronic device 100 is in the photographing mode, two keys are similarly disposed on the electronic device 100 to correspond to different encryption manners, wherein the first shutter key 120a has a function of photographing and encrypting the screen content, and the second shutter key 120b has only a photographing function. The first shutter key 120a or the second shutter key 120b may be a virtual key displayed on the screen 110 of the electronic device 100 or a physical key configured on the electronic device 100, but the present application is not limited thereto. Therefore, the user can select and press the first shutter release button 120a and the second shutter release button 120b according to the encryption requirement, and the electronic device 100 can perform a corresponding encryption method on the shot picture, thereby simplifying the process of encrypting the shot picture by the user.
In addition, the encryption method of the above embodiments can also be applied to a video recording function to encrypt a recorded film. For example, in one embodiment, the first shutter button has the function of recording and encrypting recorded content, while the second shutter button has only the function of recording. The user can select and press the first shutter button and the second shutter button according to the encryption requirement, and the electronic device 100 can execute a corresponding encryption mode on the recorded content, so that the process of encrypting the recorded content by the user is simplified.
The application of the above-mentioned film and video encryption can also be applied to the sharing of live broadcast films. For example, in one embodiment, when the user presses the first button, the live movie is encrypted, and when the user presses the second button, the live movie is not encrypted. The method for encrypting the live broadcast film may be, for example, only allowing a specific user to see the encrypted live broadcast film, where the specific user may be, for example, a user registered in a specific website or service sharing the live broadcast film, or a user belonging to the same group as the user who captured the live broadcast film.
Likewise, the encryption method of each of the above embodiments may also be applied to a recording function to encrypt recorded content. For example, in one embodiment, the first key has a function of recording and encrypting the recording content, and the second key only has a recording function. The user can select and press the first key and the second key according to the encryption requirement, and the electronic device 100 executes a corresponding encryption mode on the recorded content, so that the process of encrypting the recorded content by the user is simplified.
In another embodiment of the present application, the electronic device 100 may also be provided with two keys to encrypt the partial content in the displayed screen and the screenshot of the whole screen. For example, fig. 6 is a flowchart illustrating a screen content encryption method according to an embodiment of the present application. Referring to fig. 6, the method of the present embodiment is applied to the electronic device 100 of fig. 1, and the detailed steps of the screen content encryption method of the present application will be described below with reference to various elements in the electronic device 100.
In step S610, the first button 120a disposed on the electronic device 100 is used to detect the user' S operation to generate a first trigger signal, and the processor 130 encrypts the content displayed on the screen accordingly. In step S620, the second button 120b disposed on the electronic device 100 is used to detect the user' S operation to generate a second trigger signal, and the processor 130 extracts a screenshot of the screen and encrypts the screenshot. The detection and encryption manners of the steps S610 and S620 are the same as or similar to those of the steps S410 and S420 in the foregoing embodiment, and therefore are not described herein again.
Unlike the previous embodiments, the two keys provided in the electronic device 100 of the present embodiment respectively correspond to a part of the content and the whole content (i.e. the whole screen) in the displayed screen. When the user sees that the screen content includes files with known file formats such as e-mail, short message, text, document, photo, image, audio or video, the first button 120a can be directly pressed to generate the first trigger signal, and the processor 130 can recognize the files with the known file formats from the screen content and encrypt only the recognized files. On the other hand, when the user needs to save the content of the whole screen without limiting the file therein, the second button 120b can be pressed to generate the second trigger signal, and at this time, the processor 130 will directly extract the screenshot of the screen and encrypt the extracted screenshot.
The present application further provides a non-volatile computer-readable recording medium, wherein a computer program is recorded, the computer program is used for executing the steps of the screen content encryption method, the computer program is composed of a plurality of program code segments (for example, a program code segment for creating an organization chart, a program code segment for checking a form, a program code segment for setting a program code segment, and a program code segment for deploying a program code segment), and the program code segments are loaded into an electronic device and executed, so as to complete the steps of the screen content encryption method.
