Abstract
In a digital rights management system where a scanner is connected to a rights management server, the process of applying digital rights protection is performed by the scanner, rather than the server, so that scanning and document protection can be done even when the server is not available. Upon scanning a document, the operator selects a rights management policy to be applied to the digital document. The scanner generates a document ID, embeds the document ID as metadata in the document, encrypts the document, and stores the document ID, policy ID of the selected policy, and encryption key as an entry in a local document-policy association table on the scanner. The scanner uploads the above information of the digital document to the server, which stores the information in a document-policy association table on server and uses it to perform document access control.
