Abstract

There is disclosed a method for performing secure electronic transactions on a computer network, the network comprising a buyer'"'"'s computer, a vendor server, a creditor server and a security server. The buyer'"'"'s computer has a fingerprint file stored in the memory thereof. The method includes the steps of:

i) the buyer computer requesting to purchase merchandise to the vendor server, the purchase request including said buyer computer'"'"'s IP address;

ii) the buyer computer selecting a predetermined form of secured payment method;

iii) the payment method selection causing the vendor server to transmit to the security server a request for confirmation of the buyer computer'"'"'s identity at the buyer computer'"'"'s IP address;

iv) the confirmation request causing the security server to send a retrieval request to the IP address, the retrieval request including a retrieval program for detecting and retrieving the buyer'"'"'s computer'"'"'s fingerprint file, and the retrieval request further comprising a response request asking for confirmation of the purchase request; whereby a positive response from the buyer'"'"'s computer to the security server accompanied by the fingerprint file causes the security server to confirm the buyer computer'"'"'s identity to the vendor server and to approve the purchase.

Claims

2. ) A system for performing a secured transaction according to claim 1, wherein said buyer'"'"'s PC has received encryption programming and decryption programming from said security server.

3. ) A method for performing secure electronic transactions on a computer network, said network comprising a buyer'"'"'s computer, a vendor server, a creditor server and a security server, said buyer'"'"'s computer having a fingerprint file stored in the memory thereof, including the steps of:

i) said buyer computer requesting to purchase merchandise to said vendor server, said purchase request including said buyer computer'"'"'s IP address;

ii) said buyer computer selecting a predetermined form of secured payment method;

iii) said payment method selection causing said vendor server to transmit to said security server a request for confirmation of said buyer computer'"'"'s identity at said buyer computer'"'"'s IP address;

iv) said confirmation request causing said security server to send a retrieval request to said IP address, said retrieval request including a retrieval program for detecting and retrieving said buyer'"'"'s computer'"'"'s fingerprint file, and said retrieval request further comprising a response request asking for confirmation of said purchase request;

whereby a positive response from said buyer'"'"'s computer to said security server accompanied by said fingerprint file causes said security server to confirm said buyer computer'"'"'s identity to said vendor server and to approve said purchase.

4. ) A method of performing secure electronic transactions on a computer network, said network comprising a buying computer, an ISP computer and a vendor computer, including the steps of:
