Filed:

Mar 14, 2003

Appl. No.:

10/389488

Inventors:

Rajesh Kanungo - Sunnyvale CA, US
Hemant Thakkar - Cupertino CA, US

International Classification:

H04L009/00

US Classification:

713170000

Abstract:

Systems and methods are described for enabling documents to be controlled by a sender, in a manner which is transparent to any end recipients. The invention include mechanisms enabling a sender to control documents sent to recipient, in a manner that (1) encrypts the message to ensure its security, and (2) restricts operations the recipient may perform on the received message. The recipient and sender need not agree on a control protocol in advance of the communication. Wide distribution of a Digital Rights Management System may be facilitated by use of self-installing modules, which integrate with existing software used for document publishing and retrieval. The modules are forwarded to unregistered recipients upon authentication of the recipient, and install automatically on the recipient's computer. The modules authenticate instructions from a sender, and, per instructions from the sender, may pre-empt certain types of operations on the e-mail by the recipient
