Abstract

A transaction network contains a networked certificate authority, by which one or more virtual certificates may be remotely defined and stored, such as by an issuer user through a issuer web portal interface. An acquirer user, through an acquirer web portal interface, may acquire one or more virtual certificates, which contain a public key portion, as well as a corresponding private key, which is established at the time of acquisition, and is stored at the certificate authority. At a redemption location associated with an acquired certificate, the acquirer (or an alternate recipient of an acquired certificate to whom the acquirer has communicated the established private key), submits the certificate information, along with the established private key, to redeem the certificate.

Claims

1. A transaction system connectable to an issuer terminal associated with a redemption location and to an acquirer terminal across the Internet, comprising:

a certificate authority module comprising any of a server and a terminal connected to said Internet, said certificate authority module comprising a web portal interface comprising means for defining a virtual certificate having attributes defined by an issuer user having an issuer payment agent associated with said redemption location through said issuer terminal across said Internet, said issuer user defined attributes comprising any of denomination information, certificate design information, redemption rule information and redemption location information, said defined virtual certificate corresponding to a commodity having a value and a first public identifier, wherein said commodity corresponds to any of a product, a service, a coupon, and a reservation, said commodity selected by said issuer user at said issuer terminal in communication with said certificate authority module across said Internet, and wherein said first public identifier is defined by said certificate authority module;

a payment agent associated with said certificate authority module;

means for adding said defined virtual certificate to a database accessible through a web site connected to the Internet;

a certificate issuance module for creation of an issued certificate upon selectable acquisition of said virtual certificate by an acquirer user, having an acquirer payment agent, at said acquirer terminal across said Internet through said web site, for receipt of external payment information sent by said acquirer user from said acquirer terminal, and for transmission of information associated with said issued certificate to a holder, said holder comprising any of said acquirer user and an alternate recipient specified by said acquirer user, wherein said issued certificate comprises said first public identifier, said creation of said issued certificate associated with a private identifier which is assigned at time of said acquisition of said virtual certificate, wherein said private identifier does not appear on said issued certificate, and wherein said first public identifier and said assigned private identifier are stored at said certificate authority module in association with said issued certificate;

a certificate authentication module for authorization of a redemption of said issued certificate at said redemption location to said holder of said issued certificate, said holder comprising any of said acquirer user and said alternate recipient of said issued certificate to whom said acquirer user has communicated said private identifier, said authorization based upon a communication from said redemption location to said certificate authority module of said first public identifier from said issued certificate, a communication of said private identifier provided by said holder, and a matching comparison of said first public identifier and said private identifier stored at said certificate authority module; and

11. The transaction system of claim 1, wherein said assigned private identifier is entered by said acquirer user during said selectable acquisition of said virtual certificate.

12. The transaction system of claim 11, wherein said entered, assigned private identifier is uniquely associated with a single acquired issued certificate.

13. The transaction system of claim 11, wherein said entered, assigned private identifier is a private purchase identifier unique to said acquirer user.

14. The transaction system of claim 11, wherein said entered, assigned private identifier is a private acquirer facility access identifier unique to said acquirer user.

15. The transaction system of claim 1, wherein said assigned private identifier is established by said certificate authority module during said selectable acquisition of said virtual certificate.

37. The certificate system of claim 1, wherein said redemption comprises an offline redemption.

38. The transaction system of claim 1, wherein said redemption comprises an online redemption.

39. The transaction system of claim 1, wherein said web site is associated with said issuer user, and wherein said database stores one or more virtual certificates associated with said issuer user.

40. The transaction system of claim 1, wherein said web site has an aggregate inventory stored within said database comprising a plurality of stored virtual certificates comprising at least one other virtual certificate from an alternate issuer user other than said issuer user.

41. The transaction system of claim 1, wherein said issuer user comprises any of a merchant and a product manager associated with said redemption location.

42. The transaction system of claim 1, wherein said certificate authority further comprises means for controllable cancellation of said issued certificate by said acquirer user if the issued certificate has not been redeemed.

16. A process within a transaction network connectable to an issuer terminal associated with a redemption location and to an acquirer a terminal, comprising the steps of:

providing a certificate authority module comprising any of a server and a terminal connected to the Internet, said certificate authority module having a web portal interface comprising means for defining a virtual certificate having attributes defined by an issuer user having an issuer payment agent associated with said redemption location through said issuer terminal, said issuer user defined attributes comprising any of denomination information, certificate design information, redemption rule information and redemption location information;
