Abstract

A method and system for protecting digital objects transmitted over a network. A sender creates a notification specifying an object to be delivered to a recipient as well the object's security policy and any authentication information required to access the object. The notification is sent to an object server which creates an identifier associated with the object and sends an e-mail message with the identifier to the recipient. The recipient may access the object by referencing the identifier. The object server authenticates the request for the object and redirects the request to a security server. The security server protects the object in accordance with the security policy designated by the sender and combines the object with mobile code to enforce the security policy at the recipient's computer. The protected object is sent to the recipient. When the recipient tries to access the object, the mobile code executes and instantiates the object's security policy and object controls for enforcing the security policy at the recipient. The object may only be accessed in accordance with the security policy. An audit trail of actions related to the object may also be established.
