ABSTRACT:
A data handling mechanism, wherein a small binary tag is appended to data (each message and file) for controlling the access and handling of the data. The tag contains dedicated bits for indicating its various usage rights such as copying, forwarding, editing and also right to edit the tag itself. The tag is created by an author of the data or by any other party handling the data, including middleware agents and possible recipients of the data based on contextual information such as network or ownership domain of the author and/or of the recipient.
