Abstract
To install a black box on a computing device, an administrator has access to the computing device and queries same for machine properties thereof. The administrator sends the machine properties of the computing device to a black box server as part of a request for a new black box for the computing device. The black box server in response constructs the new black box based in part on the machine properties so as to tie the new black box to the computing device, and delivers the new black box to the administrator. The administrator thereafter installs the new black box on the computing device. The administrator may include an activation provider running on the computing device and an activation manager in communication with the activation provider. The administrator may also deactivate the black box if it determines that the black box is no longer trustworthy.
