A method and apparatus securely transmit data between a client and a server over a communications network. The secure data transmission includes, after the client is initially authenticated, (a) transmitting a series of client connection messages from the client to the server at least while the data is being transmitted, (b) transmitting a series of server connection messages from the server to the client at least while the data is being transmitted; (c) monitoring the client connection messages at the server; (d) monitoring the server connection messages at the client; (e) if a disturbance is found either in the client connection messages or the server connection messages, terminating the data transmission between the client and the server, re-authenticating the client, and re-transmitting the data; and (f) if the encrypted data is successfully transmitted to the server, storing the data in a database associated with the recipient.
