Abstract
The invention relates to an apparatus and for facilitating the reauthentication of a user using a client computer to a server computer. In one embodiment, the method includes the steps of receiving, by the server, confidential information during a first communication session between the server and a client, encrypting the confidential information with a key to create encrypted confidential information, and storing the encrypted confidential information in the server's memory. The method also includes the steps of transmitting, by the server, the key to the client and deleting, by the server, the key from the server's memory. When the server receives the key from the client during a second communication session, the server uses the key to decrypt the encrypted confidential information.
