Abstract
Official abstract text for this publication.
Private message system, method, and apparatus are described. A private message that includes encrypted data and identifying information indicating a recipient client device authorized to read the private message is stored at a server computer. Since the client devices perform all encryption and decryption processing, the server computer stores the private message in a platform agnostic manner and without performing any encryption/decryption related processes. Although any number of recipient devices can receive the private message, only a recipient client device authorized in accordance with the identifying information can read the private message.
