Abstract
A method implemented in a system including a copier or scanner connected to a digital rights management (DRM) server, which can prevent unauthorized copy or scan while allowing authorized users to obtain high quality hardcopies or scans. After the copier or scanner scans an input hardcopy document, the server determines whether the scanned document image matches any protected document in the DRM system. If a match is found, and the server determines that the user is permitted to copy or distribute the document, the server transmits an electronic version of the matched document from the DRM system to the copier or user-selected email recipients, so that the user or the email recipients can receive a high quality document. If a matched document is found but the user is not permitted to copy or distribute it, the copier or scanner deletes the scanned document image without printing or saving it.
