Private electronic information exchange

A non-transitory computer readable storage medium that provides instructions, which when executed on a processing system, cause said processing system to perform a method comprising:

• registering a sender to enable the sender to access services of a private domain in order to allow the sender to use the private domain for electronic information transmissions between members of the private domain;
• receiving, at a server associated with the private domain, data from the sender indicating that the sender is initiating the transmission of electronic information in the private domain to a recipient;
• determining, at the server associated with the private domain, whether the recipient is a member of the private domain by examining a record of members of the private domain;
• providing to the sender, from the server associated with the private domain, a public cryptographic key associated with the recipient when the recipient is determined to be a member of the private domain;
• receiving, at a server associated with the private domain, electronic information to be delivered to a recipient from the sender, the electronic information comprises at least a portion of the electronic information encrypted by a symmetric cryptographic key that is unique for the transmission of the electronic information, and wherein the electronic information further comprises a security package that contains an encrypted version of the symmetric cryptographic key, the encrypted version of the symmetric cryptographic key encrypted by the sender using the public cryptographic key of the recipient to enable the recipient to decrypt the symmetric cryptographic key and then decrypt the at least a portion of the encrypted electronic information;
• and
• transmitting the electronic information, with the security package, over an electronic network to the recipient.
