Flexible and secure enterprise rights management based on trusted virtual domains
The requirements for secure document workflows in enterprises become increasingly sophisticated, with employees performing different tasks under different roles using the same proprietary platform. Particularly, fine-grained access control to document information is necessary in certain scenarios where the integrity and confidentiality of parts of documents is of high priority.
