Abstract
Abstract A practical method and system for supplementing or replacing current security protocols used on public networks involving the distribution of a proprietary system for use on a public network access provider's network. The proprietary system includes processing hardware and proprietary software. The proprietary system transmits private data, outside the internet, over proprietary lines to a back-end process. When a "sender" sends private data it is sent over the proprietary system to a back-end process. The back-end process returns a time sensitive token which the "sender" sends to the "receiver". The "receiver" takes the time sensitive token and uses it to either retrieve the private data, over a proprietary system, or initiate a transaction with a financial institution. Encryption is used to allow authentication of the participants. This method can be used in conjunction with Secure Socket Layer (SSL) encryption and/or the Secure Electronic Transaction (SET) protocol.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
113 words
A transaction apparatus for securing an exchange between a sender and a receiver, the sender sending sender data that includes private data, said apparatus comprising: a public network providing a communication medium between the sender and a receiver designated by the sender; a local system trusted by the sender with sender data; a transaction processor connected to the designated receiver by said public network; and a nonpublic network connecting said local system and said transaction processor, said transaction processor receiving sender data from said local system over said nonpublic network and maintaining private data thereof in strict confidence while facilitating the exchange between the sender and the designated receiver over said public network.
Claim 2
Dependent Claim
113 words
A transaction apparatus for securing an exchange between a sender and a receiver, the sender sending sender data that includes private data, said apparatus comprising: a public network providing a communication medium between the sender and a receiver designated by the sender; a local system trusted by the sender with sender data; a transaction processor connected to the designated receiver by said public network; and a nonpublic network connecting said local system and said transaction processor, said transaction processor receiving sender data from said local system over said nonpublic network and maintaining private data thereof in strict confidence while facilitating the exchange between the sender and the designated receiver over said public network.
Claim 3
Dependent Claim
50 words
The transaction apparatus of claim 1, wherein the nonpublic network is selected from the group consisting of a dedicated telephone line, a private telephone line, a wireless data link, a wide area network, an optical network, a radio frequency data link, an intranet, a virtual private network, and combinations thereof.
Claim 4
Dependent Claim
12 words
A transaction apparatus as claimed in claim 1 further comprising a token.
Claim 5
Dependent Claim
13 words
A transaction apparatus as claimed in claim 3, wherein said token is time-sensitive.
Claim 6
Dependent Claim
17 words
A transaction apparatus as claimed in claim 4, wherein said token expires according to coordinated universal time.
Claim 7
Dependent Claim
13 words
A transaction apparatus as claimed in claim 3, wherein said token is encrypted.
Claim 8
Independent Claim
110 words
A method of securing an exchange in a transaction conducted over a public network by a sender and a receiver designated by the sender, said method comprising the steps of: accessing said public network to designate a receiver; entrusting a trusted local system with sender data that includes data private to the sender; accessing a nonpublic network that connects said trusted local system with a transaction processor trusted to maintain private data in strict confidence; transmitting said sender data from said trusted local system to said trusted transaction processor whereby said transaction processor manages said private data in strict confidence while facilitating said transaction between the sender and the receiver.
Claim 9
Independent Claim
110 words
A method of securing an exchange in a transaction conducted over a public network by a sender and a receiver designated by the sender, said method comprising the steps of: accessing said public network to designate a receiver; entrusting a trusted local system with sender data that includes data private to the sender; accessing a nonpublic network that connects said trusted local system with a transaction processor trusted to maintain private data in strict confidence; transmitting said sender data from said trusted local system to said trusted transaction processor whereby said transaction processor manages said private data in strict confidence while facilitating said transaction between the sender and the receiver.
Claim 10
Dependent Claim
45 words
A method of securing transactions as claimed in claim 7, further comprising the steps of: at said trusted transaction processor, generating a token in response to receipt of said sender data; and transmitting said token over said public network in lieu of said sender data.
Claim 11
Dependent Claim
20 words
A method of securing transactions as claimed in claim 8, wherein said public network communicates said token to the receiver.
Claim 12
Dependent Claim
15 words
A method of securing transactions as claimed in claim 9, wherein said token is time-sensitive.
Claim 13
Dependent Claim
19 words
A method of securing transactions as claimed in claim 10, wherein said token expires according to coordinated universal time.
Claim 14
Dependent Claim
18 words
A method of securing transactions as claimed in claim 11, further comprising the step of encrypting said token.
Claim 15
Dependent Claim
54 words
A method of securing transactions as claimed in claim 7, wherein the nonpublic network is selected from the group consisting of a dedicated telephone line, a private telephone line, a wireless data link, a wide area network, an optical network, a radio frequency data link, an intranet, a virtual private network, and combinations thereof.
Claim 16
Dependent Claim
28 words
A method of securing transactions as claimed in claim 7, further comprising the step of; encrypting said sender data prior to the step of transmitting said sender data.
Claim 17
Dependent Claim
53 words
A method of securing transactions as claimed in claim 12, wherein the step of encrypting employs a technique selected from the group consisting of digital encryption standard protocol, secure electronic transaction protocol, secure socket layer protocol, public key encryption protocol, symmetric key encryption protocol, Diffie-Hellman key agreement protocol, Ajtai-Dwork cryptosystem, and combinations thereof.
Claim 18
Dependent Claim
53 words
A method of securing transactions as claimed in claim 14, wherein the step of encrypting employs a technique selected from the group consisting of digital encryption standard protocol, secure electronic transaction protocol, secure socket layer protocol, public key encryption protocol, symmetric key encryption protocol, Diffie-Hellman key agreement protocol, Ajtai-Dwork cryptosystem, and combinations thereof.
