Patent ID: 8266421

Claim:
A method comprising: accepting a subscription to services of a private domain by a sender in order to allow the sender to use the private domain for electronic information transmissions; associating a number of electronic information transmissions that the sender is able to send with a predetermined threshold; limiting the number of electronic information transmissions that the sender is able to send through the private domain to the predetermined threshold, wherein the predetermined threshold comprises a number of transmissions per a period of time; receiving electronic information to be delivered to a recipient from the sender; establishing a network connection with one or more servers hosting the private domain; logging into the server using an identifier uniquely identifying a sender of the electronic information before transmitting the electronic information; generating a symmetric cryptographic key that is unique for the transmission of the electronic information, wherein a new symmetric cryptographic key is generated for each new transmission of electronic information; receiving a public cryptographic key associated with the recipient; encrypting at least a portion of the electronic information using the symmetric cryptographic key that is unique for the transmission; encrypting the symmetric cryptographic key that is unique for the transmission using the public cryptographic key of the recipient to generate a security package for the encrypted portion of the electronic information stored in the server to allow the recipient to decrypt the symmetric cryptographic key and then decrypt the encrypted electronic information; transmitting the security package to the server; and transmitting the electronic information over an electronic network with a private routing address that is routable within the private domain which is a subset of the electronic network.
