Abstract
One or more embodiments of the invention provide a method, apparatus, and article of manufacture for preventing unauthorized access to digital services comprising. Access control to digital services is distributed among a plurality of physically separate and independently controlled nonvolatile memory components on a system bus. The plurality of nonvolatile memory components are then communicatively coupled to a microprocessor. The microprocessor is configured to use state information in the nonvolatile memory components to provide desired functionality and enforce one or more security policies for accessing the digital services.
