Abstract
A list of computing components to be disabled can be distributed through a computer readable medium to computing devices. A process on these computing devices can read the list and disable listed components. The components can be permanently disabled, or disabled for a limited purpose. A list or list update may be provided with a digital media object that specifies a more or less stringent revocation policy for that object. A media object may also specify a maximum age for the list. This allows owners of digital media to control the stringency of media protection for their property. The process that accesses the list may prompt updates to the list, informing users of component disabling, and prompt replacement of disabled components. Finally, the invention provides techniques for securely transmitting and storing the list to protect it from alteration by unauthorized entities.
