Abstract
A secure distribution system utilizes a content viewer that consists of an applet that is downloaded to a user's conventional browser when the user logs into a publisher's server. The content viewer requests a selected document from the server by referring to the document name or URL. The server retrieves the document and forwards it to the viewer in encrypted form. The viewer then computes a document identifier from the encrypted document and uses the identifier to request a key in order to decrypt the document. The key is forwarded from the server to the viewer that then decrypts the document and displays it in the viewer. Since the document is processed by the viewer and displayed only in a window associated with the viewer, none of the conventional browser functions has to be disabled. Further, since the document is downloaded in encrypted form, it cannot be stored or forwarded using the conventional browser.
