US 2015/0310271 A1 · SECURITY IMPROVEMENTS FOR TICKETS

Abstract

A method of validating the authenticity of a ticket including a unique ticket identifier generated at an issuing terminal in accordance with a confidential algorithm is provided. The method includes receiving one or more identification variable values expressed with respect to a first coordinate measurement domain, the one or more identification variable values enabling the location of ticket verification information within the unique ticket identifier to be determined, using a coordinate transform function configured to map coordinate values from the first coordinate measurement domain to a second coordinate measurement domain to calculate one or more values of the one or more received identification variable values with respect to the second coordinate measurement domain, extracting the verification information from the unique ticket identifier on the basis of the calculated identification variable values, and verifying the authenticity of the ticket on the basis of the extracted verification information.

Dependent claims

A method of validating the authenticity of a ticket comprising a unique ticket identifier generated at an issuing terminal in accordance with a confidential algorithm, the unique ticket identifier comprising ticket verification information combined with extraneous information, and the method comprising the steps of:

receiving one or more identification variable values expressed with respect to a first coordinate measurement domain, the one or more identification variable values enabling the location of the ticket verification information within the unique ticket identifier to be determined;
using a coordinate transform function configured to map coordinate values from the first coordinate measurement domain to a second coordinate measurement domain to calculate one or more values of the one or more received identification variable values with respect to the second coordinate measurement domain;
extracting the verification information from the unique ticket identifier on the basis of the calculated identification variable values;
and
verifying the authenticity of the ticket on the basis of the extracted verification information.

2 more elements

A method of generating a ticket comprising a unique ticket identifier, the unique ticket identifier providing a verification means for verifying the authenticity of the ticket, the method comprising the steps of:

generating the unique ticket identifier by combining ticket verification information with extraneous information in accordance with a confidential algorithm;
and
defining one or more identification variable values, the identification variable values enabling the ticket verification information to be distinguished from the extraneous information within the unique ticket identifier, to enable a ticket verification entity to determine the authenticity of the ticket by verifying the ticket verification information.

A ticket authentication terminal arranged to verify the authenticity of a received ticket comprising a unique ticket identifier, the unique ticket identifier comprising ticket verification information combined with extraneous information, the ticket verification terminal comprising:

a ticket receiving module arranged to receive a ticket for authentication;
a receiver arranged to receive one or more identification variable values expressed with respect to a first coordinate measurement domain, the one or more identification variable values enabling the location of the ticket verification information within the unique ticket identifier to be determined;
a processing module arranged to calculate one or more values of the one or more identification variable values with respect to a second coordinate measurement domain;
an extracting module arranged to extract the verification information from the unique ticket identifier on the basis of the calculated one or more identification variable values;
and
a ticket authentication module arranged to determine the authenticity of the ticket on the basis of the extracted verification information.
