Abstract: A system and method of exchanging assets splits authentication of the parties in the transaction from real-time validation of the assets used in the transaction. Electronic representations of currency or other value of an asset provide a mechanism for the electronic transfer of the ownership of those assets. Digital tokens or other electronic money is created, issued, purchased, validated, and redeemed within an electronic exchange. Ownership of the token is established by the physical possession of the token along with a public key certificate that decrypts the owner's copy of the token. Tokens are stored in digital wallets and are transferred using private p2p communications channels or NFC. The separation of the authentication of the parties using an authentication authority (registry) and the validation of the assets using a transaction authority allows personal anonymity. Privacy is maintained, and no single authority has a complete audit trail of the transaction.

Abstract: A sending computer (sender) delivers private messages over a network via dynamically established encrypted channels where no copies of the message are persisted on third party computers. Private messages are routed dynamically based on membership status of the receiving computer (receiver) and direct addressability status of the sender and receiver. The system determines membership status of the receiver and provides a notification message and delivery link to the receiver when the receiver is not a member of the private network. When the receiver is a member, direct addressability of sender and receiver is determined, and the message is delivered directly to the receiver over an encrypted channel when the sender is directly addressable. When the sender is not directly addressable, the encrypted channel between the sender and receiver is established through a third party relay without persisting a copy of the private message on the third party relay.

Abstract: Methods and systems are provided for the exchange of digital cash employing protocols for various entities to separately certify the validity of the parties, values and transactions while maintaining the anonymity of the buyer or user of the digital cash. Encrypted connections are established allowing various parties to enter into transactions to buy, sell, exchange and recover digital cash using a secure method that protects the personal information and identity of the user. The parties exchange tokens for other value in a transaction of financial settlement between themselves and wherein they are the only parties with knowledge of the amount and description of the transaction and in this way mimics a traditional cash transaction.

Abstract: A private document delivery system and method includes a sending computer configured to transmit an electronic document over a computer network, a dynamically established encrypted line to traverse the computer network from a receiving computer to the sending computer where the delivery address of the receiving computer is resolved at the time of transmission of the private message such that no third parties to the message receive a permanent copy of the message. The system and method also includes a signaling mechanism configured to notify the receiving computer that the electronic document is waiting for delivery. The system and method includes a verification agent configured to verify the receiving computer's identity with a protocol specified by the sending computer and to provide access instructions to the receiving computer with which the receiving computer locates the sending computer via the dynamically established encrypted line and receives the transmitted electronic document.
