When the mobile phone raises the front camera, the mobile phone does not enter a camera shooting interface, and only the work of acquiring the face image is carried out. The acquiring of the face image comprises: at least two face images are obtained. The mobile phone uploads the acquired face image to the mobile phone chip for processing, and the next step 302 of the process is entered.
Specifically, the face image in the current scene is identified through the physical device in the mobile phone and the face detection function of the camera. For example, a first face image in a current scene is identified according to a distance between a face and a mobile phone screen when the user operates the mobile phone. The default first face image is closest to a mobile phone screen and is defined as the first face image through calculation of a sensor in the mobile phone. The preset condition is at least one of the following conditions: the face image is not matched with the first preset face image; and/or the number of the face images is multiple.
And judging whether the first face image is the user himself or not according to the face image which is input into the user in advance, namely the first preset face image. If the first face image is determined to be the user himself, the first face image may proceed to the next step 303 of the process. And/or if the first face image is determined not to be the user himself, the first face image does not need to enter the next step 303 of the process.
Specifically, the number of face images in the current scene is identified through physical devices in the mobile phone and the face detection function of the camera. And sequentially defining the first face image, the second face image, the third face image, the fourth face image and the Nth face image according to the distance between the face and the mobile phone screen when the user operates the mobile phone. Therefore, the first face image is the closest to the mobile phone screen by default, and so on. For example, the number of face images in the current scene is two face images. According to the distance between the two face images and the mobile phone screen, the first face image is acquiescent to be closest to the mobile phone screen and is defined as the first face image and the second face image in sequence through calculation of a sensor in the mobile phone.
If it is determined that only one face image is obtained, i.e. the user himself, then the next step 304 of the process need not be entered. And/or if the second face image is acquired, that is, the second face image is determined to exist, entering the next step 304 of the process.

Further, the screen display content is hidden and/or the screen display parameters are adjusted. The adjusting screen display parameters comprises at least one of: a dark screen color, a screen off, or a screen displaying a particular picture.
For example, when the first face image is recognized not to be the user himself, or the second face image is recognized, that is, the sight of other people steals the mobile phone screen of the user. The mobile phone can flash the indicator light to prompt the privacy of the mobile phone of the user to be stolen and protected. And the brightness and the color of the screen are adjusted to be dark, the screen is turned off or a specific picture is displayed. Similarly, the appearance of the third face image and the Nth face image is the same, namely, the sight of other people steals the mobile phone screen of the user.
More optimally, different protection modes can be provided according to different scenes in the embodiment. The protection mode includes at least one of: a security mode, otherwise known as a peep-proof mode, a personal self-timer mode. In practice, all modes may be set according to user requirements.
For example, in the personal self-timer mode, if there are a plurality of face images, a reminder message is output. When the user and the whole family are self-photographed together, the reminding information can be output firstly due to privacy protection, and the user can close the reminding.
For example, in the security mode or the peep-proof mode, if the face image is not matched with a preset face image, reminding information is output. This is suitable for use in crowded public areas. The mobile phone flickering indicating lamp can play a role in timely reminding the user, meanwhile, the mobile phone cannot jump to an interface shot by a camera, and the interface which is operated by the user cannot be suddenly influenced. And when the emergency situation that the crowd is crowded is met, for example, a mobile phone needs to be turned on to make a call, the indicating lamp flickers to remind the vision of strangers around, but the user can select to continue operating the mobile phone interface. Therefore, the operation is more humanized, the public places are more convenient, and the user can not delay urgent events due to special conditions.
Specifically, the user may turn off the indicator light to signal that an alert has been received, such as when the phone flashes the indicator light to indicate that the user's privacy of the phone is being stolen. While not abruptly affecting the interface the user is operating. When the emergency situation that people are crowded is met, for example, a mobile phone needs to be turned on to make a call, the indicating lamp flickers to remind the vision of strangers around, but the user can select to receive the reminding signal, turn off the indicating lamp and continue to operate the mobile phone interface, so that the operation is more humanized, and the emergency situation cannot be delayed due to special situations.
Therefore, the embodiment prompts the user to carry out privacy protection operation through the flashing of the indicating lamp, so that the safety of information of the user when the user uses the mobile phone can be protected, the prompting effect on privacy protection in the prior art can be improved, the operation is more humanized, public places are more convenient, and the use experience of the user is greatly improved.
A fourth embodiment of the present application relates to a privacy protection method applied to a mobile terminal, including: acquiring a face image, and judging whether the first face image is matched with a preset face image or not; and further, judging whether the second face image is matched with the preset face image, if not, outputting a reminding message, hiding the screen display content and/or adjusting the screen display parameters. The reminding information comprises at least one of the following: indicator light/screen brightness change, indicator light/screen color change, vibration, pattern, animation, text, sound.
The following describes implementation details of the privacy protection method of the present embodiment in detail, and the following is only provided for easy understanding and is not necessary for implementing the present embodiment.
Please refer to fig. 4, which is a flowchart illustrating a privacy protecting method according to a fourth embodiment of the present application. The method comprises the following specific steps:
Specifically, when the user opens the mobile phone, the screen of the mobile phone is lighted, that is, the mobile phone is in a working state. For example, in a public place with more people, the user selects to turn on the protection mode switch, and the mobile phone responds to the turning on of the protection mode switch. The protection mode includes at least one of: a security mode, otherwise known as a peep-proof mode, a personal self-timer mode. In practice, all modes may also be included according to user requirements.
After the user starts the protection mode, the method further comprises the following steps: and inputting the face image of the user, and setting the face image as a first preset face image.
When the mobile phone raises the front camera, the mobile phone does not enter a camera shooting interface, and only the work of acquiring the face image is carried out. The acquiring of the face image comprises: at least two face images are obtained. The mobile phone uploads the acquired face image to a mobile phone chip for processing, and the next step 402 of the process is entered.
In step 402, it is determined whether the first face image is the user himself.
Specifically, the number of face images in the current scene is identified through physical devices in the mobile phone and the face detection function of the camera. And sequentially defining the first face image, the second face image, the third face image, the fourth face image and the Nth face image according to the distance between the face and the mobile phone screen when the user operates the mobile phone. Therefore, the first face image is the closest to the mobile phone screen by default, and so on. For example, the number of face images in the current scene is two face images. According to the distance between the two face images and the mobile phone screen, the first face image is acquiescent to be closest to the mobile phone screen and is defined as the first face image and the second face image in sequence through calculation of a sensor in the mobile phone.
And judging whether the first face image is the user himself or not according to the face image which is input into the user in advance, namely the first preset face image. If the first face image is determined to be the user himself, the first face image may proceed to the next step 403 of the process. And/or, if the first face image is determined not to be the user himself, the first face image does not need to enter the next step 403 of the flow.
Further, if the second face image is defined as calculated by a sensor in the mobile phone, the next step 403 of the process is executed to calculate and compare the similarity of the face images. Similarly, there may be a third face image, a fourth face image and an nth face image, and the next step 403 in the process is also entered to calculate and compare the similarity of the face images.
Specifically, according to the judgment of the previous step 402, it is assumed that the first face image is closest to the mobile phone screen and is the user himself. Therefore, whether the second face image and the Nth face image possibly appearing later are matched with the preset face image is directly judged. The method for judging matching of the preset face images is to calculate and compare the similarity of the face images. Positioning, correcting and face segmenting the acquired face image by a face detection technology, namely standardized feature extraction; the nose, eyes and mouth of the human face are regarded as characteristic points, and the positions of the characteristic points are marked to calculate the similarity. And measuring the distance and the angle of the acquired face image and the preset face image and each characteristic point of the two face images, calculating to obtain the similarity of the two faces, and finally informing a calculation result to a computer of the mobile terminal, wherein the calculation result is similar or dissimilar. If the calculation results are similar, the second face image matches the preset face image, and the process returns to step 402 to determine whether the user is the user himself. And/or, if the calculation results are not similar, the second face image does not match the preset face image, and then the next step 404 of the flow is entered.
If a third face image appears in the scene, the face detection process is finished to judge whether the third face image is matched with the preset face image or not according to the steps of the second face image. Likewise, the same is true for the nth face image.
Further, whether the first face image is matched with a preset face image or not is judged.
Specifically, it is determined in the previous step 402 that the first face image is not the user himself/herself as a default. Therefore, whether the first face image is matched with the preset face image or not is directly judged. If the calculation results are similar, the first face image matches the preset face image, and the process returns to step 402 to determine whether the first face image is the user himself. And/or if the calculation results are not similar, the first face image does not match the preset face image, and then the next step 404 of the flow is entered.
And step 404, outputting reminding information.
Specifically, the reminding information includes at least one of the following: indicator light/screen brightness change, indicator light/screen color change, vibration, pattern, animation, text, sound. Further, the screen display content is hidden and/or the screen display parameters are adjusted. The adjusting screen display parameters comprises at least one of: a dark screen color, a screen off, or a screen displaying a particular picture.
For example, an indicator light may be blinked to indicate to the user that privacy needs to be protected. When the first face image or the second face image is recognized to be not the user, namely the sight of other people steals the mobile phone screen of the user. The mobile phone can flash the indicator light to prompt the privacy of the mobile phone of the user to be stolen and protected. And the brightness and the color of the screen are adjusted to be dark, the screen is turned off or a specific picture is displayed. Similarly, the appearance of the third face image and the Nth face image is the same, namely, the sight of other people steals the mobile phone screen of the user.
The mobile phone flickering indicating lamp can play a role in timely reminding the user, meanwhile, the mobile phone cannot jump to an interface shot by a camera, and the interface which is operated by the user cannot be suddenly influenced. And when the emergency situation that the crowd is crowded is met, for example, a mobile phone needs to be turned on to make a call, the indicating lamp flickers to remind the vision of strangers around, but the user can select to continue operating the mobile phone interface. Therefore, the operation is more humanized, the public places are more convenient, and the user can not delay urgent events due to special conditions.
Specifically, for example, when the mobile phone flashes an indicator light to indicate that the privacy of the mobile phone of the user is being stolen, the user may turn off the indicator light to signal that a reminder has been received, return to step 402, and continue to protect the privacy of the user in the always-on protection mode. If the user does not turn off the indicator light, the next step 406 of the process is entered, i.e. the user selects to turn off the screen light of the mobile phone or turn off the protection mode.
Therefore, on one hand, the mobile phone flickering indicator light plays a role in timely reminding the user, the mobile phone indicator light is selected to be turned off, the user is acquiescent with the ambient scene environment, and the ambient environment is known to have no unsafe influence on the privacy of the user. For example, when the user encounters an emergency situation that people are crowded, the mobile phone needs to be turned on to make a call, the indicating lamp flickers to remind the vision of strangers around, and the user selects to turn off the indicating lamp so as to continue to operate the original interface of the mobile phone and avoid delaying the emergency situation due to special situations.
On the other hand, the user selects not to turn off the indicator light, and can select to turn off the mobile phone screen. For example, when the user is in a crowded car, personal information in the screen of the mobile phone is completely exposed to the sight of strangers. Under the unavoidable condition, the user can also play a role in privacy protection by selecting to suspend the mobile phone to work. Similarly, the user can select to turn off the mobile phone protection mode without turning off the indicator lamp. For example, the user plays a mobile phone with family at home, watches the same mobile phone program together, or the individual self-timer mode, and at this moment, the protection mode can be closed, so that the human face detection identification and the mobile phone flickering indicator lamp can not occur, and the power consumption of the mobile phone can be reduced.
Specifically, the user selects not to turn off the indicator light, and can select to turn off the mobile phone screen. For example, when the user is in a crowded car, personal information in the screen of the mobile phone is completely exposed to the sight of strangers. Under the unavoidable condition, the user can also play a role in privacy protection by selecting to suspend the mobile phone to work. Similarly, the user can select to turn off the mobile phone protection mode without turning off the indicator lamp. For example, the user plays a mobile phone with family at home, watches the same mobile phone program, and at this time, the protection mode can be closed, so that face detection identification and a mobile phone flickering indicator lamp can not occur, and the power consumption of the mobile phone can be reduced.
Therefore, the embodiment prompts the user to carry out privacy protection operation through the flashing of the indicating lamp, so that the safety of information of the user when the user uses the mobile phone can be protected, the prompting effect on privacy protection in the prior art can be improved, the operation is more humanized, public places are more convenient, and the use experience of the user is greatly improved.
In the specific embodiment, a privacy protection method and apparatus are also provided, which are applied to a mobile terminal.
Please refer to fig. 5, which is a schematic diagram of a privacy protecting apparatus according to an embodiment of the present application. The method comprises the following specific steps:
Specifically, the obtaining unit 501 at least includes a built-in image obtaining unit, and the image obtaining unit is configured to obtain face image information uploaded by a camera in real time.
It is noted that, in order to better implement the method of the present application, the obtaining unit 501 further includes an image storage unit. The image acquisition unit sends the face image information uploaded in real time to the image storage unit, and the image storage unit stores the image information respectively. The storage unit is used for storing the face image of the user as a first preset face image. The storage unit is further used for storing the face image of the second user as a second preset face image.
Specifically, in the first judging unit, the number of face images in the current scene is identified through the physical device in the mobile phone and the face detecting function of the camera. And sequentially defining the first face image, the second face image, the third face image, the fourth face image and the Nth face image according to the distance between the face and the mobile phone screen when the user operates the mobile phone. Therefore, the first face image is the closest to the mobile phone screen by default, and so on.
Specifically, in the second determination unit, it is determined whether the first face image is the user himself or herself, based on a first preset face image, which is a face image entered in advance into the user. And if the first face image is the closest to the mobile phone screen, directly judging whether the second face image and the face image possibly appearing later meet the preset conditions. The method for judging whether the preset conditions are met is to calculate and compare the similarity of the face images. Positioning, correcting and face segmenting the acquired face image by a face detection technology, namely standardized feature extraction; the nose, eyes and mouth of the human face are regarded as characteristic points, and the positions of the characteristic points are marked to calculate the similarity. And measuring the distance and the angle of the acquired face image and the preset face image and each characteristic point of the two face images, calculating to obtain the similarity of the two faces, and finally informing a calculation result to a computer of the mobile terminal, wherein the calculation result is similar or dissimilar. If the first face image is judged not to be the user himself, the first face image needs to be judged whether the preset condition is met.
It should be noted that, after the acquisition unit identifies the acquired data as normal, the identification signal of the position of the human face feature point is sequentially sent to the first determination unit and the second determination unit. The first judging unit and the second judging unit respond according to different identification signals.
Specifically, in the execution unit, when the second face image is recognized not to be the user himself, namely, the sight of other people steals the mobile phone screen of the user. The mobile phone can flash the indicator light to prompt the privacy of the mobile phone of the user to be stolen and protected.
It should be noted that, in an actual application scenario, the reminder information includes at least one of the following: indicator light/screen brightness change, indicator light/screen color change, vibration, pattern, animation, text, sound. Further, the screen display content is hidden and/or the screen display parameters are adjusted. The adjusting screen display parameters comprises at least one of: a dark screen color, a screen off, or a screen displaying a particular picture.
It is noted that, in an actual application scenario, for a subsequent more humanized operation, the user experience is improved. In the execution unit, the user can be made to perform a selection operation to turn off the indicator lamp. For example, when the user encounters an emergency situation that people are crowded, the mobile phone needs to be turned on to make a call, the indicating lamp flickers to remind the vision of strangers around, and the user selects to turn off the indicating lamp so as to continue to operate the original interface of the mobile phone and avoid delaying the emergency situation due to special situations.
It is noted that, in a practical application scenario, the effect of privacy protection is not affected. The user selects not to turn off the indicator light and can select to turn off the mobile phone screen. For example, when the user is in a crowded car, personal information in the screen of the mobile phone is completely exposed to the sight of strangers. Under the unavoidable condition, the user can also play a role in privacy protection by selecting to suspend the mobile phone to work.
It is worth noting that in an actual application scenario, in order to adapt to diversified application scenario requirements, the user experience is better guaranteed. And when the user selects not to turn off the indicator light, the mobile phone protection mode can be selected to be turned off. For example, the user plays a mobile phone with family at home, watches the same mobile phone program, and at this time, the protection mode can be closed, so that face detection identification and a mobile phone flickering indicator lamp can not occur, and the power consumption of the mobile phone can be reduced.
