System and method for secure handling of scanned documents
First Claim
1. A system for secure handling of scanned documents comprising:
- receiving means adapted for receiving electronic document data representative of content of at least one tangible document from an associated scanner;
means adapted for assigning document identifier data to each received electronic document;
a key server includingdata storage including means adapted for storing key data representative of a plurality of encryption keys, each encryption key being associated with document identifier data corresponding thereto, andmeans adapted for communicating with an associated data network;
encryption means adapted for encrypting received electronic document data in accordance with at least one encryption key;
means adapted for communicating encrypted electronic document data to at least one destination;
means adapted for receiving user information from an associated user, which user information includes identification data corresponding to the associated user;
means adapted for receiving, from the associated user, a document access request directed to at least one selected electronic document, which document access request includes data representative of a desired access to at least one encrypted electronic document;
means adapted for communicating user information and document identifier data corresponding to the at least one selected electronic document to the key server;
testing means adapted for testing the user information to determine accessibility of the at least one selected electronic document in accordance with the user information; and
means adapted for selectively decrypting the at least one selected electronic document in accordance with key data corresponding thereto.

Abstract
A system and method for secure handling of scanned documents is provided. Electronic document data is received by a document processing device and assigned an identifier unique to the document. A user ID or electronic mail address is then received corresponding to the selected output operation. The user ID or address is then transmitted, along with the identifier, to an encryption key generator, which then generates a symmetric encryption key. The encryption key is then returned to the document processing device, whereupon the electronic document data is encrypted and the key is deleted by the document processing device. The encrypted document is then stored or transmitted via electronic mail, in accordance with the selected output operation. Decryption is thereafter accomplished using the document identifier, user ID or email address, and key generator identification data.
