Abstract
A system and method for controlling access to a message after communication. A sender sends an encrypted message to a recipient. The sender also sends an encryption key and the identity of the recipient to a services component. The recipient authenticates its access rights with the services component to obtain the encryption key. The key is held for a period of time for the recipient to access the encrypted message. The recipient may re-authenticate with the services component to again obtain the key to subsequently access the message. The sender may revoke or reinstate the receiver's access to the message by updating the service component.
