Abstract
Abstract A system and method for issuing and validating tickets. The system includes a data processing system for receiving ticket request information and generating ticket information; the ticket information including encrypted validating information, a local printing system which receives the ticket information and prints the encrypted validating information on a ticket in machine readable format, and a validating system for converting the encrypted validating information into a digital format, decrypting the validating information, testing the validating information to validate the ticket and, if the ticket is valid, downloading at least a portion of the ticket information for reconciliation of accounts; that is for reconciling ticket issuance, use, and payment. The data processing system receives an itinerary from a purchaser, checks a reservation system to determine service availability and provides service availability information to the purchaser who selects appropriate services and submits ticket request information. The data processing system then generates ticket information including encrypted validating information and transmits the ticket information to the local printing system which prints a ticket having the encrypted validating information printed in a machine readable format. When the ticket is presented to a validating system the validating system converts the encrypted validating information into a digital format, decrypts the encrypted validating information, tests the validating information to validate the ticket and, if the ticket is valid, downloads at least a portion of the ticket information for reconciliation of accounts, that is for reconciliation of ticket issuance, use and payment. A number of encryption protocols for encryption of the validating information are also disclosed.

Independent Claim
119 words
A system for issuing tickets, comprising: a) a data processing system for: a1) receiving ticket request information; and, a2) generating ticket information; said ticket information including encrypted validating information; b) a local printing system for: b1) receiving said ticket information; and, b2) printing said encrypted validating information on a ticket in a machine readable format; and c) a validating system for: c1) automatically converting said encrypted validating information in machine readable format into a digital format; c2) decrypting said encrypted validating information. c3) locally testing said validating information with respect to information on said ticket to validate said ticket; and, c4) if said ticket is valid, downloading at least a portion of said ticket information for reconciliation of accounts.
Claim 3
Dependent Claim
14 words
A system as described in claim 1 wherein said ticket is an airline ticket.
Claim 4
Dependent Claim
17 words
A system as described in claim 1 wherein said machine readable format is a two dimensional barcode.
Claim 5
Dependent Claim
36 words
A system as described in claim 1 wherein said data processing system is further for receiving and confirming payment information, and said data processing system generating said ticket information only if said payment information is confirmed.
Claim 6
Dependent Claim
44 words
A system as described in claim 1 wherein said data processing system is further for accessing a database to determine service availability and provide service availability information to a purchaser, said purchaser inputting said ticket request information in response to said service availability information.
Claim 7
Dependent Claim
30 words
A system as described in claim 1 wherein said data processing system is further for communicating with third party systems to reserve additional services for a purchaser of said ticket.
Claim 8
Dependent Claim
64 words
A system as described in claim 1 wherein said data processing system stores an encryption key E m and said validating system stores a corresponding decryption key D m , said encrypted validating information comprising information T encrypted with said key E m , and said validating system decrypts said encrypted validating information with said decryption key D m to check said information T.
Claim 9
Dependent Claim
18 words
A system as described in claim 7 wherein said information T includes information to be downloaded for reconciliation.
Claim 10
Dependent Claim
128 words
A system as described in claim 1 wherein said data processing system is one of a plurality of data processing systems, each of said plurality of data processing systems having a uniquely associated encryption key, said data processing systems storing an associated encryption key E i and a corresponding decryption key D i encrypted with an encryption key E m , and said validating system stores a corresponding decryption key D m , said validating information comprising information T encrypted with said key E i , and said encrypted decryption key, said validating system decrypting said encrypted decryption key with said decryption key D m to obtain said decryption key D i and decrypting said encrypted validating information with said key D i to check said information T.
Claim 11
Dependent Claim
