Abstract: Disclosed herein is a technique for implementing a secure lock screen on a computing device. The secure lock screen is configured to permit particular applications to display their content—such as main user interfaces (UIs)—while maintaining a desired overall level of security on the computing device. Graphics contexts, which represent drawing destinations associated with the applications, are tagged with entitlement information that indicates whether or not each graphics context should be displayed on the computing device when the computing device is in a locked-mode. Specifically, an application manager tags each application that is initialized, where the tagging is based on a level of entitlement possessed by the application. In turn, a rendering server that manages the graphics contexts can identify the tagged entitlement information and display or suppress the content of the applications in accordance with their entitlements.

Abstract translation: 这里公开了一种在计算设备上实现安全锁屏的技术。 安全锁屏被配置为允许特定应用显示其内容，例如主用户界面（UI），同时在计算设备上保持期望的整体安全级别。 代表与应用程序相关联的绘图目标的图形上下文被标记有授权信息，其指示当计算设备处于锁定模式时是否应该在计算设备上显示每个图形上下文。 特别地，应用程序管理器标记被初始化的每个应用程序，其中标记基于应用程序拥有的权限级别。 反过来，管理图形上下文的呈现服务器可以识别标记的权利信息，并根据其权利显示或抑制应用的内容。
