Abstract: A security element is displayed that provides information to a user to help ensure that they are not confused or misled into believing that content originates from a trusted source when in fact it does not. The security element shows the user the source of the content and is displayed in such a manner that the source of the content is easily viewable. For example, according to one embodiment, the security element is shown within the title bar of a window. The security element may also be temporarily shown. Providing the user with more information about the site being accessed helps them to make an intelligent decision about their browsing experience. The security element includes at least part of a domain name that identifies the source of the content. The security element may also include the entire domain name. For example, the security element may overlay the screen.

Abstract: Described is a system and method in which a system and method in which a device manufacturer or software image provider controls which devices are allowed to install or to run a software image. An image keying mechanism uses package data and UUID associated with the device or class of devices to key an image. Because the UUID is used in the key, an installer verifier and/or boot-time verifier can ensure that the device is authorized to install and/or run the image. Any package, including existing device packages or the package for which installation is requested can demand that keying be enforced. An installer mechanism checks whether the device is allowed to install the image. A boot-time enforcement mechanism prevents an improperly installed image from operating by halting the boot process if a demanded key is invalid or missing.
