Abstract

A payment method (100) suitable for network (10) transactions in merchandise (12) between purchasers (14) and vendors (18), employing the services of guarantors (16) which issue vouchers (20) for payment. The vendors (18) offer the merchandise (12) on the network (10) as URLs (50), which optionally may include a URL address (52) separated from a URL request (56). The URL (50) or the URL address (52) initially includes the network (10) address of the guarantor (16), and the URL (50) or the URL request (56) specifies particular merchandise (12). By selecting the URL (50) the purchaser (14) is initially taken to the guarantor (16), where the voucher (20) is placed into the URL (50) or the URL request (56) and the network (10) address of the vendor (18) is placed into the URL (50) or the URL address (52). The purchaser (14) is then redirected to the vendor (18), where the voucher (20) is accepted as payment before the vendor (18) releases the merchandise (12) for communication over the network (10) to the purchaser (14). The guarantor (16) may optionally also query a database (28) to initially obtain, verify, or substitute an address of a vendor (18) on the network (10) before reformatting the URL (50).

Claims

1. A method for transactions in merchandise which is content material on a network, the method comprising the steps of:

(a) a purchaser following a URL on the network, said URL including a guarantor address for a guarantor and also a specification of the merchandise;

(b) said guarantor receiving said URL and creating a voucher guaranteeing payment for purchase of said merchandise, adding said voucher to said URL, replacing said guarantor address in said URL with a vendor address for a vendor on the network, and redirecting said purchaser to said vendor on the network;

(c) said vendor receiving said URL and releasing the merchandise over the network to said purchaser.

2. The method of claim 1, wherein said URL includes a URL address and a URL request which is separated from said URL address, and said URL address including said guarantor address and said URL request including said specification of the merchandise.

3. The method of claim 1, wherein at said step (a) said purchaser follows said URL by entering said URL into a web browser.

4. The method of claim 3, further comprising placing said URL into a HTML tagged portion of a web page on the network, and in said step (a) said purchaser selecting said HTML tagged portion to follow said URL.

5. The method of claim 1, further comprising said guarantor authorizing credit for said purchaser to purchase the merchandise, and terminating the method if said credit is inadequate.

6. The method of claim 5, wherein said authorizing includes checking an account cookie, which was previously issued to said purchaser, to establish whether said purchaser now has adequate said credit.

7. The method of claim 1, wherein said voucher represents a guarantee that said guarantor is willing to pay up to a pre-set limit set by said purchaser.

8. The method of claim 1, wherein said URL further includes a price for the merchandise and said voucher represents a guarantee that said guarantor is willing to pay said price on behalf of said purchaser for the merchandise.

9. The method of claim 1, further comprising in step (b) encrypting said voucher using a private key of said guarantor, so that decryption using a corresponding public key of said guarantor verifies that said guarantor created said voucher.

10. The method of claim 9, further comprising additionally encrypting said voucher using a public key of said vendor, so that said voucher is privacy protected until decryption occurs using a corresponding private key of said vendor.

11. The method of claim 1, further comprising in step (b) looking up said vendor address in a database of vendor information.

12. The method of claim 11, wherein said vendor address is looked up using said specification of the merchandise, to permit said purchaser to omit giving a proposed address for said vendor on the network, to permit looking up and substituting said vendor address when any said proposed address is found erroneous, and to permit looking up and substituting said vendor address when any said proposed address is considered non optimal for communications between said purchaser and said vendor on the network.

13. The method of claim 12, wherein said vendor address is looked up using a proposed address supplied in said URL, to permit forwarding to said vendor address when said proposed address is obsolete, and to permit substitution of said vendor address when said proposed address is considered non optimal for communications between said purchaser and said vendor on the network.

14. The method of claim 1, wherein said URL further includes a price being tendered for the merchandise, and further comprising in step (c) reviewing said price for acceptability, and terminating the method if said price is unacceptable.

15. The method of claim 1, further comprising in step (c) examining said voucher for validity, and terminating the method if said voucher is invalid.

16. The method of claim 15, wherein examining said voucher for validity includes verifying that said voucher was created by said guarantor.

17. The method of claim 15, wherein examining said voucher for validity includes verifying that said voucher contains adequate payment for the merchandise.

18. The method of claim 1, further comprising in step (c) determining whether the merchandise is available, and terminating the method if the merchandise is unavailable.

19. A system for transactions in merchandise available as content material on a network, the system comprising:

(a) means for a purchaser to order the merchandise by following a URL on the network, where said URL includes a guarantor address for a guarantor and also a specification of the merchandise;

(b) means for said guarantor to receive said URL, to create a voucher guaranteeing payment for said merchandise, to add said voucher to said URL, to replace said guarantor address in said URL with a vendor address for a vendor on the network, and to redirect said purchaser to said vendor on the network;

(c) means for said vendor to receive said URL and to release the merchandise over the network to said purchaser.

20. The system of claim 19, wherein said URL includes a URL address and a URL request which is separated from said URL address, and said URL address includes said guarantor address and said URL request includes said specification of the merchandise.

21. The system of claim 20, wherein:

said means for a purchaser is a computer running a browser program and said purchaser follows said URL by entering said URL into said browser program.

29. The system of claim 20, further comprising a database of vendor information, for looking up said vendor address.

30. The system of claim 29, wherein said database is accessible using said specification of the merchandise to look up said vendor address, to permit said purchaser to omit giving a proposed address for said vendor on the network, to permit look up and substitution of said vendor address when any said proposed address is found erroneous, and to permit look up and substitution of said vendor address when any said proposed address is considered non optimal for communications between said purchaser and said vendor on the network.

31. The system of claim 30, wherein said database is accessible using a proposed address supplied in said URL, to permit look up of said vendor address when said proposed address is obsolete, and to permit substitution of said vendor address when said proposed address is considered non optimal for communications between said purchaser and said vendor on the network.
