Description

Technical Field

[0001] This application relates to the technical field of application software, and particularly to a method, an electronic device, and a storage medium for preventing UI screenshots. Background Art

[0002] Emerging online content such as online novels and short dramas, due to their fast-paced and fragmented characteristics, has greatly enriched people's spare time. Their content going global has also well spread China's excellent culture and promoted the development of the industrial economy. For such content playback software, how to avoid software content being stolen and recorded and conduct copyright protection is of top priority.

[0003] Since the iOS system does not have a direct method to prevent screenshot / screen recording, the design concept of the iOS system is that what the user can see can be obtained, that is, when the user performs a screenshot / screen recording operation, all the content currently visible on the screen will be saved. This easily leads to the leakage or sharing of some key information on the page, affecting the company's revenue. For example, content such as online novel content and video content is screenshot / screen recorded and then shared on the Internet, resulting in information leakage.

[0004] Existing technical solutions for preventing screenshots of such software will, when the user performs a screenshot / screen recording operation, first give a UI prompt to remind of copyright and information protection. When the number of screenshots exceeds a certain number or the screen recording exceeds a certain time, the App usage will be directly restricted, or a UI pop-up window will be used to block the valid content. When adopting the screen recording interface blocking scheme, when screen recording or taking a screenshot, an overlay is added to the content page view to hide the content to be protected, and the content seen by the user is the same as the actual recorded content. This will cause the UI interface to be unable to view the novel or video content normally due to the blocking within a short time after the user takes a screenshot, affecting the user experience. Summary of the Invention

[0005] In order to help improve the problem of the existing anti-screenshot scheme blocking content and affecting the user experience, this application provides a method, an electronic device, and a storage medium for preventing UI screenshots.

[0006] In a first aspect, this application provides a method for preventing UI screenshots, adopting the following technical solution: Create a function for finding screenshot / screen recording content protection through the system text control, remove it from the parent view of the system text control, and use it as the container for the view that needs to prevent leakage; Monitor the user's screenshot and / or screen recording operation, and determine whether a preset anti-screenshot and / or screen recording condition is triggered; When the preset condition is reached, replace the screenshot and / or screen recording content with an invalid page through the password mode of the screenshot / screen recording content protection function.

[0007] By adopting the above technical solution, it not only does not affect the user's continued use of the App, but also achieves the protection effect of information and prevents it from being leaked.

[0008] In a second aspect, the present application provides an electronic device, adopting the following technical solution: An electronic device, the electronic device includes: At least one processor; A memory; At least one application program, wherein at least one application program is stored in the memory and is configured to be executed by at least one processor, and the at least one application program is configured to: execute a method for preventing UI screenshot.

[0009] In a third aspect, the present application provides a computer-readable storage medium, adopting the following technical solution: A computer-readable storage medium, on which a computer program is stored. When the computer program is executed on a computer, the computer is made to execute any one of the methods for preventing UI screenshot provided in the first aspect.

[0010] In summary, the present application includes at least one of the following beneficial technical effects: This method calls the built-in screenshot / recording content protection function of the system through the system text control, and realizes the content protection function of novel and video software. When the user performs a screenshot / recording operation, only blank content will be captured / recorded. While realizing the protection of key information / copyright, it also avoids the effective content being blocked by the UI pop-up window. After the user takes a screenshot / records the screen, the APP can still be used normally, which greatly improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the Figures 1-4 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0013] The embodiments of the present application provide a method for preventing UI screenshots, which is used in content reading / viewing software.

[0014] In this embodiment, the e - book reading APP system is taken as an application example to specifically illustrate the above - mentioned method. In actual implementation, the above - mentioned method can also be used in other software systems, such as short - video APPs, computer web pages, etc. This embodiment does not make any limitations in this regard.

[0015] Specifically refer to Figure 1 As shown, a method for preventing UI screenshots includes: S10: Create a screenshot / recording content protection function through the system text control, remove it from the parent view of the system text control, and use it as the container for the view that needs to prevent leakage. S20: Monitor the user's screenshot and / or screen recording operations, and determine whether the preset anti - screenshot and / or screen recording conditions are triggered. S30: When the preset conditions are reached, replace the screenshot and / or screen recording content with an invalid page through the password mode of the screenshot / recording content protection function.

[0016] This solution introduces an anti - screenshot component, breaks through the limitations of the screenshot content of the iOS system, modifies the existing logic, so that when the user triggers the screenshot limit condition, a white screen is directly captured, which not only does not affect the user's continued use of the App, but also achieves the effect of information protection and prevents its leakage.

[0017] Based on this embodiment, further, when this solution is applied to the content interface of reading software or video software in the iOS system, the copyright of the text content in the reading software can be protected through this solution.

[0018] In the solution of this embodiment, specifically, in step S10: Create a search for UITextLayoutCanvasView through the UITextField control, remove it from the UITextField parent view, and use it as the container for the view that needs to prevent leakage.

[0019] On this basis, further, specifically in step S30: When the preset conditions are reached, replace the screenshot and / or screen recording with a blank page through the password mode of UITextLayoutCanvasView.

[0020] In an embodiment of the embodiments of the present invention, when it is detected that the user is performing a screen recording operation, the screen recording result is replaced with a blank page.

[0021] In another embodiment of the embodiments of the present invention, when it is detected that the number of times the user takes screenshots exceeds the preset value, all the screenshot results are replaced with blank pages.

[0022] Of course, the screenshot result can also be replaced with other types of invalid pages, as long as they do not carry online article content or video screenshots, and are not limited to the description in this embodiment.

[0023] Among them, when it is detected that the user performs a screenshot operation for the first time, a copyright information protection prompt, such as "Do not screenshot", etc., is pushed at a position in the UI that does not block the content.

[0024] This method realizes the content protection function of novels and video software. When the user performs a screenshot / screen recording operation, only blank content will be captured / recorded. While realizing the protection of key information / copyright, it also avoids the effective content being blocked by the UI pop-up window, and the user can still use the APP normally after screenshotting / screen recording.

[0025] In another embodiment of the present invention, through the research of the inventor, it is found that the iOS system will protect the content in the password box. When taking a screenshot or screen recording encounters the password box, it will automatically display as blank. That is, when the UITextField control enables the password mode, the content inside cannot be captured. The main structure of UITextField is as shown in the appendix Figure 2 As shown, it mainly includes two sub-views, namely UITouchPassthroughView and UITextLayoutCanvasView. Among them, UITextLayoutCanvasView can play a role in protecting the screenshot content in the password mode.

[0026] Since Apple does not provide a method for creating UITextLayoutCanvasView, but provides the creation of UITextField. In actual use of this method, UITextLayoutCanvasView is found through the creation of the UITextField control, and it is removed from the parent view of UITextField and used as the container of the view that we need to prevent leakage, as shown in Figure 3 As shown, so as to achieve effective information protection without affecting Apple's review. After using the UITextLayoutCanvasView control, when the user performs a screenshot / screen recording operation again, only blank content will be captured / recorded. At the same time, in this embodiment, a friendly UI prompt can be added to inform the user that blank content is obtained due to key information / copyright protection. Through the above solutions, it is possible to neither affect the user's continued use of the App nor achieve the purpose of information protection and prevention of leakage.
