In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
The invention provides a method for protecting camera privacy, which can comprise the following steps of:
and step S11, receiving the image data collected by the camera.
And step S13, carrying out face recognition on the image data to obtain face features.
Step S15, executing a privacy protection mode according to the human face characteristics, wherein the privacy protection mode at least comprises one or more of the following modes: turning off the power supply of the camera and deleting the image data.
Specifically, with reference to fig. 2, in this scheme, on the basis that an existing camera is not changed, a privacy protection device may be added outside the camera, the privacy protection device is connected to the camera and the server, the privacy protection device may receive image data collected by the camera first, and then perform face recognition on the image data to obtain face features, and then the privacy protection device determines whether to execute the privacy protection device according to the face features, it should be noted that, with reference to fig. 2, the privacy protection device is connected to a data interface, a control interface, and a power interface of the camera, and the privacy protection device may control to cut off a power supply of the camera or delete the image data collected by the camera.
The camera power supply can be cut off through the relay, or can be cut off in a mode of replacing a triode, a field effect transistor and the like according to the type of the camera.
It should be noted that, after obtaining the face feature, the privacy protection apparatus may determine whether to execute the privacy protection mode according to a preset policy, for example, if the face feature represents a female, the privacy protection mode is executed, and for example, if the face feature represents a minor female, the privacy protection mode is executed.
In the scheme, the privacy protection device is independent of the camera and does not have a network online control function, so the privacy protection device can not be controlled by a hacker, and the camera can be closed or the image can be deleted according to the recognized human face characteristics, so the scheme receives the image data collected by the camera; carrying out face recognition on the image data to obtain face features; executing a privacy protection mode according to the human face characteristics, wherein the privacy protection mode at least comprises one or more of the following modes: the power supply of the camera is turned off and the image data is deleted, so that the technical problem that the privacy of a user is easily revealed in the existing camera technology is solved.
Optionally, the step S15 of executing the privacy protection mode according to the human face features may include:
and step S151, controlling a relay to close the power supply of the camera under the condition that the human face characteristics are matched with a human face database prestored locally.
Specifically, can prestore the white list in the database that privacy protection device visited, the face data of prestoring in the above-mentioned white list then is the object that needs to carry out privacy protection mode, can at first transmit image data to privacy protection device in the camera normal operating time, privacy protection device can carry out face identification to image data, it is only white list personnel in the data that the judgement camera acquireed, privacy protection device can cut off the power of network camera, through the method of this scheme, can filter white list user's privacy data, can also pass through the power that the relay cut off the camera according to user's wish, make the camera stop work.
It should be noted that before the privacy protection device takes effect, the protected white list face data needs to be stored in the privacy protection device, and the privacy protection device is configured, for example, whether to turn on the privacy protection, whether to turn off the power supply of the camera during protection, whether to take effect when only a white list exists or when white list user data exists, and the like. After the configuration is completed, if the privacy protection is started and the power supply of the camera is turned off during protection, image data can be transmitted to the privacy protection device firstly during normal work of the camera, the privacy protection device can identify the face of the image data, and when the data acquired by the camera is judged to be only white list personnel, the privacy protection device can cut off the power supply of the network camera through a relay.
Optionally, the method may further include: and under the condition that the human face characteristics are not matched with a local pre-stored human face database, carrying out cloud storage on the image data.
Specifically, if the face features are judged to be absent and the white list is judged, the privacy protection device can upload the image data to the cloud server for storage, and the normal monitoring function of the camera is achieved.
Optionally, before receiving the image data acquired by the camera in step S11, the method in this embodiment may include:
step S10, receiving configuration information input by the user, the configuration information being used to update the privacy protection mode.
Specifically, a configuration interface is arranged in the privacy protection device, a user can input face feature data of a white list through the interface, the user can configure the face feature data through a wireless mobile phone APP, or can configure the face feature data by inserting a memory card, and the like.
An alternative embodiment of the present solution is described below with reference to fig. 3:
the user deposits white list face data and configuration parameters in privacy protection device inside, then, privacy protection device carries out face identification to the image data that the network camera uploaded, if only have the white list personnel in the data that the camera acquireed through face identification technology judgement, then privacy protection device passes through the power of relay cutting off network camera, if do not have the white list personnel in the data that the camera acquireed through face identification technology judgement, then privacy protection device passes through the power of relay recovery network camera to upload image data to cloud ware.
Example two
As shown in fig. 4, the present solution provides a selectable method for protecting privacy of a camera, where the method may include:
and step S41, after receiving the image data collected by the camera, controlling to close the camera.
And step S43, carrying out face recognition on the image data to obtain face features.
