A method for processing display data is implemented by an electronic data processing device. The display data represents at least one piece of information to be displayed on a screen. The method includes: for obtaining at least one reference image representing the at least one piece of information to be displayed; and generating at least one altered image from the reference image and from at least one alteration parameter.

A communication apparatus displays an image on a display unit, transmits a display image displayed on the display unit to another communication apparatus by wireless communication, transmits a confirmation image for confirming a transmission destination of the display image to the another communication apparatus by wireless communication to display the confirmation image on the another communication apparatus, selects, by a user operation, whether to transmit the display image to the another communication apparatus, after transmission of the confirmation image and before transmission of the display image, and transmits the display image to the another communication apparatus if it is selected in the selecting to transmit the display image.

A system and method are presented for determining window geometry. In an embodiment, a party to an interaction using a streaming video connection may want to share content on their display with another party to the interaction. A party may wish to annotate an on-screen target for the other party. In an embodiment, markers or magic bars may also be used to map the screens to each other in addition to coordinates. When one party annotates an on-screen target on their display, the coordinates on the party's display are translated for the other party and the annotation is placed in the intended location on that party's screen. Masking of content may also be performed such that contact on one user's screen may not be visible to the other party during the screen share.

An electronic device includes a display and a controller that controls screen display of the display. When the mode immediately before suspension of screen display of the display is a first mode, the controller displays a security lock screen before resuming screen display of the display, and when the mode immediately before suspension of screen display of the display is a second mode, the controller resumes screen display of the display while selectively causing the security lock screen not to be displayed.

Provided is an information processing apparatus, including: a line-of-sight detection unit configured to detect lines of sight of a plurality of users with respect to presentation information; and an area determination unit configured to determine, on the basis of the detected lines of sight of the plurality of users, a shared area that is visually recognized by the plurality of users to share information and a confidential area that is not visually recognized by another user to keep information of each user confidential.

Various examples for providing for the secure view of content on devices are disclosed. In one example, a content modification service, such as an email modification service, can access a document from a server destined for a client device and generate a modified form of the document by adjusting a visual setting associated with a display of the content that affects an ability to view the content from an area beyond a predetermined range. The content modification service or a client application can selectively provide the document or the modified version of the document in a display of the client device based on a setting of the client device, a device profile, or compliance rules specified by an administrator of a management service.

A predetermined process is executed in accordance with a state of a detection target which has been detected through short range communication with the detection target. In a case where a control device (100) has determined that a location of an NFC tag (30) detected by a display device (10) had changed, the control device (100) causes the display device (10) to transmit predetermined information to the communication terminal (20) via an NFC antenna (11).

Technologies for secure z-order enforcement include a computing device having a processor with secure enclave support. A secure enclave invokes an EBIND instruction with display programming information that includes a z-order enforcement policy indicating whether the secure enclave requests z-order enforcement for an overlay surface associated with the secure enclave. The processor generates wrapped programming information in response to invoking the EBIND instruction. An untrusted supervisor component such as a device driver invokes an UNWRAP instruction with the wrapped programming information. The processor unwraps the wrapped programming information and programs a display controller with the z-enforcement policy. The processor may read a z-order enforcement status register of the display controller to determine if an overlay surface is available. For z-order enforcement, the display controller composes the overlay surface associated with the secure enclave in front of all other overlay surfaces of the display controller. Other embodiments are described and claimed.

A continuous glucose monitor for wirelessly transmitting data relating to glucose value to a plurality of displays is disclosed, as well as systems and methods for limiting the number of display devices that can connect to a continuous glucose transmitter. In addition, security, including hashing techniques and a changing application key, can be used to provide secure communications between the continuous glucose transmitter and the displays. Also provided is a continuous glucose monitor and techniques for authenticating multiple displays, providing secure data transmissions to multiple displays, and coordinating the interaction of commands and data updates between multiple displays.

The disclosure relates to a method and apparatus for displaying an application interface. The method includes detecting a starting operation over a specified application; in response to detecting the starting operation over the specified application, determining whether the specified application is a secret-related application; when the specified application is determined to be the secret-related application, acquiring an encrypted display manner of the specified application; and sending application interface data and the encrypted display manner of the specified application to a first terminal based on a network connection pre-established with the first terminal, wherein the application interface data is used by the first terminal to generate an application interface of the specified application, and the encrypted display manner is used by the first terminal to display the application interface with an encrypted effect.
