Abstract
The method prevents disclosure of protected information in a platform. The platform includes a plurality of entities () and a security manager (). Each entity () has data which indicates whether the entity is trusted or untrusted and whether the entity has or has not been exposed to protected information. The untrusted entity () requests () an unsafe operation of a trusted entity (). The trusted entity () notifies the security manager () of the requested operation. The trusted entity () then halts the requested operation if the untrusted entity () contains protected information or has been exposed to protected information.
