The Rights Management Add-on for Internet Explorer is a way that Windows users can view files with restricted permission. These restrictions help people to prevent sensitive documents, Web-based information, and e-mail messages from being forwarded, edited, or copied by unauthorized individuals.
Document authors, Web site authors, and creators of Web-based applications can deliver protected information by restricting permission. This provides protection, not only while the information is in transit, but also after the recipient of the information has received it.
