United States Patent 6,330,670England , et al. December 11, 2001

------------------------------------------------------------------------Digital rights management operating system

Abstract

A digital rights management operating system protects rights-managed data, such as downloaded content,from access by untrusted programs while the data is loaded into memory or on a page file as a result of theexecution of a trusted application that accesses the memory. To protect the rights-managed data resident inmemory, the digital rights management operating system refuses to load an untrusted program into memorywhile the trusted application is executing or removes the data from memory before loading the untrusted

program. If the untrusted program executes at the operating system level, such as a debugger, the digital rightsmanagement operating system renounces a trusted identity created for it by the computer processor when thecomputer was booted. To protect the rights-managed data on the page file, the digital rights managementoperating system prohibits raw access to the page file, or erases the data from the page file before allowingsuch access. Alternatively, the digital rights management operating system can encrypt the rights-manageddata prior to writing it to the page file. The digital rights management operating system also limits thefunctions the user can perform on the rights-managed data and the trusted application, and can provide atrusted clock used in place of the standard computer clock.
