ABSTRACT:
A system includes a server to store a first portion of a message, and a client to store a complementary second portion of the message. The first portion of the message is encrypted and a message specific token comprising one or more encryption keys used to encrypt the first portion of the message is generated. The second portion of the message stored on the client is subsequently combined with the message-specific token to form a partially secured message at the client. Furthermore, the partially secured message including the message-specific token is delivered from the client to a recipient to facilitate access to both the first and second portions of the message by the recipient.
