Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 shows an image encryption method according to an embodiment of the present invention, which is applied to a mobile terminal, and includes:
step S1: and receiving fingerprint input of a user under the condition that a display screen of the mobile terminal displays the target image.
The fingerprint input is commonly used in a scene such as a fingerprint unlocking scene and a fingerprint payment scene.
The present embodiment applies fingerprint input to an image encryption and decryption scenario.
In the fingerprint input of the step, the user can input the fingerprint information on the display screen, and if the mobile terminal recognizes that the fingerprint information input by the user is the same as the preset fingerprint information, the fingerprint input of the user is received so as to trigger the action related to the fingerprint input.
Preferably, a fingerprint identification area can be set on the display screen and used for receiving fingerprint input of a user, so that false triggering caused by false operation of the user is avoided.
Further, a plurality of fingerprint identification areas can be set on the display screen so as to be suitable for different states of the mobile terminal, and different fingerprint identification areas can correspond to different preset fingerprint information so as to be convenient for a user to operate.
For example, when the mobile terminal is in a vertical screen state, a fingerprint identification area can be set at a position where a finger of a user is convenient to touch based on a gesture of the user holding the mobile terminal, and if the thumb is easier to touch the fingerprint identification area, fingerprint information of the thumb is recorded as preset fingerprint information. When the mobile terminal is in the horizontal screen state, the relevant setting is carried out according to the gesture of the user in the state.
Step S2: in response to the fingerprint input, a target region of a target image displayed by the display screen is identified.
In this step, the mobile terminal is triggered to recognize a target area of a target image displayed on the display screen in response to the fingerprint input.
Preferably, the identification is performed using image recognition techniques.
Further, the identified content is not limited to the range, attribute, status, etc. characteristics of the target area.
The target area may be an area of the entire image content displayed by the display screen; but also an area of the partial image content displayed by the display screen.
Step S3: the state of the target area is acquired.
And judging whether the target area is currently in an encrypted state or an unencrypted state based on the state characteristics of the identified target area.
Step S4: and encrypting the target area under the condition that the target area is in an unencrypted state.
In this step, for example, a mosaic may be added to the target area; as another example, other common background images may be displayed in the target area.
Wherein the background image is e.g. a cartoon image, a scenic image, etc.
In this embodiment, based on the features of the identified target region, different animation effects may also be added during the encryption process.
For example, if the target area is identified as a high building, encryption can be performed based on different floors, so as to achieve the animation effect of layer-by-layer encryption, and make the encryption more interesting.
Preferably, the target image may be a still image, such as a picture; the target image may also be a dynamic image, such as a video.
Wherein, for dynamic images, the dynamic images can be decomposed into static images corresponding to multiple frames.
In the embodiment of the invention, under the condition that the display screen displays the target image, a user can input fingerprints on the display screen, so that after the mobile terminal successfully identifies fingerprint information corresponding to the fingerprints, the target area of the target image can be identified in the display screen, and the target area is encrypted based on the current unencrypted state of the target area. Compared with the prior art, the target image is encrypted as one file, and the target area in the target image is encrypted under the condition that the target image is displayed, so that the requirement that a user only wants to encrypt and protect part of content can be met.
In addition, the fingerprint identification technology is applied to the image encryption method, so that user operation is simplified, and the method is suitable for operation habits of users.
Compared with the method for encrypting the whole image as one file in the prior art, the method can be realized through fingerprint input when the whole image is encrypted, so that the operation steps of setting passwords and the like are avoided, and the user operation is simplified.
Preferably, the target image in the embodiment of the present invention is a 2D image or a 3D image.
Fig. 2 shows an image encryption method according to another embodiment of the present invention based on the embodiment shown in fig. 1, and after step S3, the method further includes:
step S5: and decrypting the target area when the target area is in an encrypted state.
In this step, the encryption effect is removed to display the target area.
In this embodiment, based on the features of the identified target area, different animation effects may also be added during decryption.
For example, if the target area is identified as a high building, decryption can be performed based on different floors, so as to achieve the animation effect of layer-by-layer decryption, and encryption is more interesting.
Fig. 3 shows an image encryption method according to another embodiment of the present invention, based on the embodiment shown in fig. 2, applied to a mobile terminal with a folded double-sided screen, including a first screen and a second screen.
The step S1 comprises the following steps:
step S11: in the case where the first screen and the second screen together display the same target image, a first fingerprint input of the user within a first fingerprint recognition area of the first screen is received and/or a second fingerprint input of the user within a second fingerprint recognition area of the second screen is received.
Referring to fig. 4, a first fingerprint recognition area 11 is provided on the first screen 1, the first fingerprint recognition area 11 being for receiving a first fingerprint input of a user on the first screen 1; a second fingerprint recognition area 21 is provided on the second screen 2, the second fingerprint recognition area 21 being for receiving a second fingerprint input from a user on the second screen 2.
When the first screen 1 and the second screen 2 jointly display the same target image 3, if the user wants to encrypt and decrypt the image content displayed on the first screen 1, a first fingerprint input is input in the first fingerprint recognition area 11; if the user wants to encrypt and decrypt the image content displayed on the second screen 2, a second fingerprint input is input in the second fingerprint recognition area 21.
Wherein, different preset fingerprint information can be input for different display screens. In this way, the user can input fingerprint inputs through different fingers at the same time on the first screen 1 and the second screen 2 to encrypt and decrypt the image contents displayed on the first screen 1 and the second screen 2 at the same time.
Preferably, based on the basic gesture of the user holding the double-sided folding mobile terminal with two hands, the thumb of the left hand and the thumb of the right hand are usually correspondingly positioned on the first screen 1 and the second screen 2 respectively, so that the first fingerprint identification area 11 and the second fingerprint identification area 21 can be respectively arranged at positions which are easy to be contacted by the user, further, the fingerprint information of the thumb of the left hand is input for matching with the fingerprint information in the first fingerprint input, and the fingerprint information of the thumb of the right hand is input for matching with the fingerprint information in the second fingerprint input. Therefore, the user can operate conveniently and quickly, the operation habit of the user is very suitable, the user does not need to hold the mobile terminal by one hand, and the fingerprint input is carried out by separating the mobile terminal by one hand, so that the mobile terminal is not easy to drop.
Further, referring to the orientation shown in fig. 4, the first screen 1 is positioned on the left side and the second screen 2 is positioned on the right side, so it is conceivable that the thumb of the left hand facilitates the input of fingerprint information in the first fingerprint recognition area 11 of the first screen 1, and the thumb of the right hand facilitates the input of fingerprint information in the second fingerprint recognition area 21 of the second screen 2, so that the preset fingerprint information corresponding to the first fingerprint recognition area 11 is preferably the fingerprint information of the thumb of the left hand, and the preset fingerprint information corresponding to the second fingerprint recognition area 21 is preferably the fingerprint information of the thumb of the right hand. In yet other embodiments, the mobile terminal folded with the dual-sided screen may also exhibit other orientations, such as inverted placement, where the first screen 1 is on the right and the second screen 2 is on the left. Therefore, in order to facilitate the user operation, a plurality of fingerprint recognition areas may be provided on the display screen, so as to ensure that the thumb of the left hand can match the preset fingerprint information in the fingerprint recognition area of the left display screen, and the thumb of the right hand can match the preset fingerprint information in the fingerprint recognition area of the right display screen, regardless of how the user holds the mobile terminal.
In addition, the image encryption method of the double-screen double-fingerprint can further improve encryption grade and further protect user privacy.
Correspondingly, step S2 includes:
step S21: identifying a first target area of the first screen display in response to the first fingerprint input; and/or, in response to the second fingerprint input, identifying a second target area of the second screen display.
Preferably, the first target area is the entire image content displayed by the first screen; the second target area is the entire image content of the second screen display.
The target image comprises a first target area and/or a second target area.
In the embodiment of the invention, the method for encrypting and decrypting the images is provided for the mobile equipment with the folding double-sided screen, and the operation modes and interactive applications of the folding double-sided screen on the mobile equipment are enriched. On one hand, the same target image can be displayed simultaneously based on two display screens, so that the display effect is better; on the other hand, the double-screen display displays the same target image, so that a user can encrypt and decrypt the image content displayed by each display screen respectively, and can encrypt and decrypt the image content of two display screens simultaneously. It should be noted that, in this embodiment, based on the operation habit of the user, the operation mode and the interactive application suitable for the human body are reasonably set, so that the user experience is better.
In more embodiments, when the first screen and the second screen respectively display independent target images, the user may encrypt and decrypt the target images displayed on each display screen respectively, or may encrypt and decrypt the target images of both display screens simultaneously.
The embodiment is more suitable for the situation that the target image is a 3D image, and because the image content of the 3D image includes 360 ° viewing angles, the image content is more, so that the 3D image is displayed in two display screens at the same time, the viewing angles are more convenient for users to view and change, and further the processing such as encryption and decryption is performed.
Fig. 5 shows an image encryption method according to another embodiment of the present invention based on the embodiment shown in fig. 1, where the method further includes, in a case where a display screen of a mobile terminal displays a target image:
step S6: touch input is received from a user selecting a target area on a display screen.
Referring to fig. 6, in a case where the display screen 4 of the mobile terminal displays the target image 3, the user may make a touch input on the display screen for selecting a target area among the target images while inputting fingerprint information in the fingerprint recognition area 41 or before inputting fingerprint information in the fingerprint recognition area 41, thereby recognizing a target area selected by the user through the touch input in response to the user's fingerprint input in the fingerprint recognition area 41.
Alternatively, after receiving the fingerprint input of the user, if the user selects a target area on the display screen through the touch input, the target area selected by the user is automatically identified.
In one case, the mobile terminal may automatically recognize the entire image content displayed on the display screen as the target area upon receiving the fingerprint input of the user. The embodiment provides a method for encrypting and decrypting the local image content in the display screen, and the user can randomly select the local content to encrypt and decrypt based on the image content displayed by the display screen so as to meet the personalized requirements of the user.
Fig. 7 shows an image encryption method according to another embodiment of the present invention based on the embodiment shown in fig. 5, and step S6 includes at least any one of the following:
step S61: and receiving a region dividing input of a user on the display screen for the target region.
The user may define a closed area on the display screen as the target area by the scribe-lane input.
Step S62: a user press input to a target area on a display screen is received.
In this step, the user presses a finger on the display screen to cover an area as a target area in the press input.
In this embodiment, the input mode of selecting the target area is further listed, so that more services can be provided to the user, and the user can select the target area in different input modes according to different situations.
Fig. 8 shows an image encryption method according to another embodiment of the present invention based on the embodiment shown in fig. 1, where in a case where a display screen of a mobile terminal displays a target image, the method further includes:
step S7: and receiving an adjustment input of a user on the target image.
Wherein the adjustment input includes any one of zoom-in, zoom-out, movement, and rotation.
In this embodiment, in a case where the display screen of the mobile terminal displays the target image, the user may perform adjustment input such as enlargement, reduction, movement, rotation, and the like on the target image.
In one case, after the mobile terminal receives the fingerprint input of the user, the mobile terminal can automatically identify the whole image content displayed by the display screen as a target area, and encrypt and decrypt the whole image content. Therefore, in this step, the user can adjust the display position of the target image on the display screen by adjusting the input, so that the image content, which needs to be encrypted and decrypted, in the target image is displayed on the display screen.
It should be noted that, the user may perform the adjustment input and the fingerprint input simultaneously, or may perform the adjustment input and the fingerprint input sequentially, without limitation of the sequence.
Referring to fig. 9, for example, if the user wants to encrypt the area of the target image displayed on the second screen 2, compared to fig. 4, but the area displayed on the second screen 2 is larger, the user may move the target image to the left by adjusting the input, so that the area of the target image displayed on the second screen 2 is reduced, and further, the user may fingerprint input on the second screen 2 to encrypt the reduced area.
For another example, the target image is displayed on the display screen, and if the user wants to encrypt the first area included in the target image, the user can zoom in the target image by adjusting the input until only the first area is displayed on the display screen, and then the user can input the fingerprint on the display screen to encrypt the first area.
For another example, the user may rotate the target image by adjusting the input to only the area that needs to be encrypted to be displayed on the display screen, so that the user may fingerprint in on the display screen to encrypt the area that needs to be encrypted.
Particularly, in the case that the target image is a 3D image, since some areas in the 3D image are invisible under a certain viewing angle, the user can also adjust the display viewing angle and display position of the 3D image on the display screen by rotating the mobile terminal, so that the target area to be encrypted is determined in different display viewing angles, and the display screen only displays the target area to be encrypted.
Step S8: and adjusting the display position of the target image on the display screen in response to the adjustment input.
And adjusting the display position of the target image on the display screen according to the adjustment input of the user so as to enable the target area expected by the user to be displayed on the display screen.
In this embodiment, the user may perform adjustment input on the target image to adjust the display position of the target image on the display screen, so as to achieve that the target area desired by the user is displayed on the display screen, and the user may directly encrypt or decrypt the target area through fingerprint input. In contrast to the embodiment shown in fig. 5, in this embodiment, the user can clearly view the target area on the display screen to determine whether encryption or decryption is required.
It should be noted that, the user may adjust the display position of the target image on the display screen through adjustment input to the target image, so that the target area is displayed on the display screen; the user may also select a target area on the display screen by touch input. The user can select an input mode according to own needs and operation habits so as to meet the personalized demands of the user.
