摘要：An electronic mail system and method in which a message receiver creates anenvelope containing envelope media data that is hidden with an embedding-and-extracting key. The message sender acquires the message receiver's envelope and, usingan embedding-and-extracting key, embeds a secret message in the acquired envelope
media data. The embedded envelope is sent to the message receiver, who extracts thesecret message from the received embedded envelope using the same embedding-and-extracting key used to embed the data. As a result a secret message can be sent fromthe sender to the receiver without being eavesdropped on during the communication.
