All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
According to an embodiment of the present application, there is provided a screen control method, it being noted that the steps shown in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.
Fig. 1 is a flowchart of a screen control method according to an embodiment of the present application, as shown in fig. 1, including the steps of:
step S102, under the condition that the target object is detected in the preset range of the large screen, determining the current risk level of the large screen.
The preset range in the above steps may be a range in which the content displayed on the large screen can be viewed or a range in which a peeping event easily occurs. The target object may be a sensitive target, for example, an illegal person, a person performing a peeping action, a peeping device, a peeping action, etc., where the peeping device may include, but is not limited to, a mobile phone, a tablet, a camera, a micro device with a lens, etc., and the peeping action may include a hand or an arm being placed in front of a screen, or a face being too close to the screen, etc., but is not limited to this, and may be set according to practical situations.
The current risk level in the above step is used for representing the leakage degree of the key information displayed on the large screen, and the higher the risk level is, the easier the key information displayed on the large screen is leaked.
Step S104, determining a target image source device based on the current risk level and the security levels of the plurality of image source devices, wherein the large screen is formed by splicing a plurality of screens, and each screen is used for displaying the display image of the corresponding image source device.
The importance of the information in the image is different for different image source devices, and the more important the information in the image is, the higher the security level of the image source device is, so that different security levels can be set in advance for different image source devices. For example, the security level may include a primary security level, a secondary security level and a tertiary security level from high to low, but is not limited thereto, and may be set according to actual needs.
The target image source device in the above step may be an image source device that needs to mask the display image.
For example, for a large screen system as shown in fig. 2, the large screen may be composed of 4 display screens spliced, that is, a screen 1, a screen 2, a screen 3, and a screen 4, the 4 display screens being connected to four image source devices through an image server, wherein the screen 1 is used for displaying a display image of the image source device 1, the screen 2 is used for displaying a display image of the image source device 2, the screen 3 is used for displaying a display image of the image source device 3, and the screen 4 is used for displaying a display image of the image source device 4.
In an alternative embodiment, the higher the current risk level, the more likely the information displayed on the large screen is leaked, and at this time, the higher the security level, the higher the leakage risk of the image source device, and thus, the image source device that needs to be shielded can be determined as the target image source device under the current risk level.
Step S106, the target screen corresponding to the target image source device is controlled to display the preset image.
The preset image in the above step may be a preset replacement image, and the replacement image may be a specific image, for example, may be a solid color image, such as a blue image.
For example, with the large screen system as shown in fig. 2, if it is determined that the image source device 1 is a target image source device, the screen 1 may be controlled to stop displaying the display image of the image source device 1, and display a preset image, for example, display a blue image.
According to the scheme provided by the embodiment of the application, under the condition that the target object is detected in the preset range of the large screen, the current risk level of the large screen is firstly determined, then the target image source equipment is determined based on the current risk level and the security levels of the plurality of image source equipment, the target image source equipment is further controlled to display the preset image, the display image of the image source equipment is not displayed any more, the image of the image source equipment with higher security level is shielded by the large screen when a suspected shooting event occurs, the image from the image source equipment cannot be seen by a user from the large screen, the technical effect of avoiding key information leakage is achieved, and the technical problem of lower security of the large screen in the related art is solved.
Optionally, determining the current risk level of the large screen includes: determining the type and the number of the detected target objects; the current risk level is determined based on the type and number of target objects.
The types in the steps can be types such as illegal users, peeping equipment, peeping actions and the like, and the suspected peeping events of different types have different corresponding risk levels. In addition, the more sensitive targets that are detected, the more likely the key information displayed on the large screen will be revealed.
In an alternative embodiment, after the target object is detected, the type of the target object may be identified, the type of each target object may be determined, and the number of target objects of the same type may be determined, so that the current risk level may be determined.
Optionally, determining the current risk level based on the type and number of target objects includes: acquiring a plurality of first intervals, wherein each first interval comprises: preset types and preset numbers and corresponding risk levels; matching the types and the numbers of the target objects with a plurality of first intervals, and determining first intervals successfully matched; and determining the risk level corresponding to the successfully matched first interval as the current risk level.
The plurality of first intervals in the above step may be preset risk level policies, including a correspondence between sensitive targets and risk levels, for example, as shown in table 1, the risk levels may be divided into a first-level risk, a second-level risk and a third-level risk, for the first-level risk, the preset types of the corresponding sensitive targets may be illegal users, and the preset number may be 2 or more; for the first-level risk, the corresponding preset type of the sensitive target can be peeping equipment, and the preset number can be 1 or more than 1; for the secondary risk, the preset type of the corresponding sensitive target can be illegal users, and the preset number can be 1; for three levels of risk, the preset type of the corresponding sensitive target may be a clapping action, and the preset number may be 1 or more than 1.
TABLE 1
In an alternative embodiment, after the type and number of the sensitive targets are identified, the first interval in which the matching is successful may be determined by matching the type and number of the sensitive targets with the sensitive targets in each first interval, and thus, the risk level corresponding to the interval may be determined to be the current risk level. For example, if the type of the sensitive object is currently identified as an illegal user, and the number of the illegal users is 1, it may be determined that the current risk level is a secondary risk.
Optionally, determining the target image source device based on the current risk level and the security levels of the plurality of image source devices includes: determining a target security level corresponding to the current risk level; and acquiring the image source equipment with the security level being greater than or equal to the target security level from the plurality of image source equipment to obtain the target image source equipment.
In an alternative embodiment, the security level to be masked may be set in advance for different risk levels, and further after determining the current risk level, a corresponding target security level may be determined, so that among the plurality of image source devices, an image device having a security level equal to or higher than the target security level may be determined as the target image source device.
Optionally, determining the target security level corresponding to the current risk level includes: acquiring a plurality of second intervals, wherein each second interval comprises: presetting a risk level and a corresponding preset safety level; matching the current risk level with a plurality of second intervals, and determining a second interval successfully matched; and determining the preset security level corresponding to the second interval successfully matched as the target security level.
The plurality of second intervals in the above step may be preset shielding rules, including a corresponding relationship between risk levels and security levels of the image source devices to be shielded, for example, as shown in table 2, the preset risk levels may be divided into a first-level risk, a second-level risk and a third-level risk, for the first-level risk, the current risk level is higher, and the images of all the image source devices need to be shielded, and the corresponding preset security levels may be the first-level security level, the second-level security level and the third-level security level; for the secondary risk, the current risk level is general, the image of the important image source equipment can be shielded, and the corresponding preset security level can be a primary security level and a secondary security level; for the third-level risk, the current risk level is lower, the highest security level, that is, the most important image of the image source device can be shielded, the corresponding preset security level can be the first-level security level, and the image of the image source device with the lower security level can be unshielded.
TABLE 2
| Risk level | Security level |
| First-level risk | A first level security level; a second level security level; three level security level |
| Two-stage risk | A first level security level; secondary security level |
| Three-level risk | First level security level |
In an alternative embodiment, after determining the current risk level, the second interval in which the matching is successful may be determined by matching the current risk level with the risk level in each second interval, and thus the security level corresponding to the interval may be determined as the target security level. For example, if the current risk level is determined to be a primary risk, the target security level may be determined to be a primary security level, a secondary security level, and a tertiary security level.
Optionally, controlling the target screen corresponding to the target image source device to display the preset image includes: the method comprises the steps of sending a target instruction to a target acquisition end corresponding to target image source equipment, wherein the target acquisition end is used for stopping acquiring a display image of the target image source equipment based on the target instruction; and sending the preset image to a target receiving end corresponding to the target screen, wherein the target receiving end is used for controlling the target screen to display the preset image.
The target instruction in the above step may be a masking instruction, that is, stopping capturing the display image of the target image source device, and stopping sending the image data to the image server.
In an alternative embodiment, after determining the target image source device, the image server may send a masking instruction to the target acquisition end S corresponding to the target image source device, where after receiving the masking instruction, the S end stops sending the image data to the image server. The image server can send preset replacement image data to a receiving end R end corresponding to the image source equipment to be shielded, the R end decodes the received replacement image data, and then the replacement image is displayed on a connected screen.
It should be noted that, because the image server is usually placed in the machine room near the large-screen device, not only the large-screen device will not display the display image of the target image source device, but also the image server will not receive the display image of the target image source device any more, so that the security can be higher.
Optionally, detecting the target object within the preset range includes: acquiring a second image in a preset range; the second image is identified and it is determined whether the second image contains the target object.
In an alternative embodiment, the user image, namely the second image, can be obtained through a camera arranged on the large screen, and whether the user image comprises a sensitive target is further identified through an AI algorithm; or directly matching the acquired user image with a preset standard image of the sensitive target in an image matching mode, and if the similarity reaches a threshold value, determining that the two images are identical, namely that the user image contains the sensitive target.

In an alternative embodiment, at least one object in the user image can be identified directly through an AI algorithm, so as to judge whether the at least one object comprises a sensitive target, and if any one object is the sensitive target, the user image can be determined to contain the target object; if all of the objects are not sensitive targets, it may be determined that the target object is not contained in the user image.

The image of the target object in the above step may be a face image of an illegal user set in advance, an image of a peeping device, a body image of an execution action, or the like, but is not limited thereto.
In an alternative embodiment, a standard image of the sensitive object may be set in the image server, where the standard image of the sensitive object includes: at least one of a face image of an illegal user, an image of a peeping device, a body image of a peeping action performed, and the like. After the image of at least one object is identified from the user image, the image of each object can be matched with the standard image of the sensitive target, if the image of a certain object is identical with the face image of an illegal user, the successful matching of the image of any object with the image of the target object can be determined, and the user image is determined to contain the illegal user; if the image of a certain object is the same as the image of the peeping device, the successful matching of the image of any object with the image of the target object can be determined, and the peeping device is contained in the user image; if the image of a certain object is the same as the body image for executing the action, the successful matching of any object with the image of the target object can be determined, and the peeping action is included in the user image.
