Abstract
This invention provides secure, policy-based separation of data and applications on computer, especially personal computers that operate in different environments, such as those including personal applications and corporate applications, so that both types of applications can run simultaneously while complying with all required policies. The invention enables employees to use their personal devices for work purposes, or work devices for personal purposes. The secure, policy-based separation is created by dividing the data processing device into two or more “domains,” each with its own policies. These policies may be configured by the device owner, an IT department, or other data or application owner.
