Abstract: The huge success of mobile computing devices has fundamentally changed the corporate computing environment, with employees using corporate data on their own computing devices. Companies would still like to control their data, event when present on an employee's personal computing device, such as a Smartphone. The present invention presents a system and a method, which will enable companies to achieve such a control while still allowing the user to use the applications he desires on his device. The protected data will be replaced by other data.
