A computing device receives a modified first image frame from a client device, wherein the client device stores the first image frame. The computing device generates a second image frame that corresponds to the modified first image frame with a watermark. The computing device transmits, to a third-party application executing at the computing device, the second image frame and generates an instruction for modifying the first image frame, the instruction based on an altered version of the second image frame that is identified by the watermark, the second image frame altered by the third-party application. The computing device transmits, to the client device, the instruction for modifying the first image frame.

A sub-pixel for an LED display, the sub-pixel comprising a first light emitting device having a first emission beam angle and a second light emitting device having a second beam angle, the second emission beam angle being different to the first emission beam angle. There is also described a display using a plurality of the sub-pixels.

Systems and methods for dynamically concealing sensitive information in a shared screen session of a video conference are disclosed. The system may establish communication with one or more computing devices active in a video conference in which each computing device may switch between a screen share mode and a video mode. The system may determine that one or more articles of sensitive information are visible in a graphical user interface associated with a first computing device of the plurality of computing devices. The system may receive a first signal from the first computing device that indicates a first intent of a host associated with the first computing device to switch the screen share mode which includes sharing the first graphical user interface with the one or more computing devices during the video conference. In response to the first signal, the system may execute one or more privacy actions.

An access medium includes a passive e-paper, display portion to display a first access element and a memory resource to store a second access element. Authentication is determined by evaluation of the first access element and evaluation of the second access element.

A visual motion CAPTCHA.

A method comprising the steps of: displaying primary data having a first sensitivity level on a first display screen that is operatively coupled to a first computer; capturing an image of the first display screen with an image capture device that is operatively coupled to a second computer that is communicatively isolated from the first computer such that no data is shared between the first and second computers; executing with the second computer a display recognition and characterization algorithm to recognize the primary data based only on the captured image of the first display screen; and augmenting the primary data by displaying secondary data on a second display, wherein the secondary data is related to, and has a higher sensitivity level than, the primary data.

Disclosed in an embodiment of the present invention is a multi-screen sharing based application management method and device, storage medium, the method comprising: determining whether an application is an application to be shared when the application is detected to start; obtaining a security attribute of the application if the application is determined to be the application to be shared, and sharing with a remote user the application matching the attribute value according to the attribute value of the security attribute.

A control system for a switchable privacy display apparatus comprises an ambient light sensor and a display luminance controller arranged to control the luminance of the display in response to measured illuminance. High image visibility is provided for public mode operation while in privacy mode visual security level above a perceived privacy threshold may be obtained by means of control of image luminance, in response to the output of the ambient light sensor.
