Description

ELECTRONIC TICKET BOOKING WITH IMPROVED PRIVACY
Field of Invention
The invention relates to a method of booking tickets electronically.
Background
Electronic tickets (e-tickets) are widely used in the ticketing systems of transportation services such as airlines, buses and trains. Current e-ticket systems are not fully secure because anybody, including an unauthorized person, who has the e- ticket and user data could easily access the boarding pass from an electronic kiosk (e- kiosk).
Moreover, current e-ticket systems do not provide any privacy protection in that user's data with flight or travelling information is exposed to the system administrator and/or operator of the service provider. As such, sensitive personal information may be available to the system operator, increasing the risk of identity theft by unscrupulous individuals.
An aim of the invention is to improve the security of such systems with respect to privacy of personal information. Summary of Invention
In an aspect of the invention, there is provided a method of booking a ticket comprising the steps of:
accessing a ticket provider's website to book a ticket;
reading a user's details from an electronic smartcard when a ticket booking is requested,
setting a personal identification number for the ticket booking;
generating an anonymous number and associating it with the ticket booking; storing said anonymous number such that the user can obtain the ticket by reading the smartcard at a ticket retrieval station;
characterised in that the user's details are encrypted with said personal identification number as a secret key.
Thus the ticket provider cannot view the user's private data as only the anonymous number is visible thereto, and only the user knows the personal identification number to allow the user's details to be retrieved. Advantageously if the smartcard was lost or stolen, or other details of the booking were obtained by a third party, the ticket would not be retrievable as the personal identification number would not be known to the third party. In one embodiment the smartcard includes a physically unclonable function. Typically the smartcard is validated via a challenge-response session.
In one embodiment the personal identification number is stored on the smartcard. Typically the personal identification number is used in the challenge-response session.
Thus the smartcard validation and booking processes can use a common authentication procedure i.e. the same personal identification number, which has the advantage of being more user- friendly.
In one embodiment the ticket booking process proceeds if a user's details and payment are verified by a financial firm.
In one embodiment the anonymous number is generated based on the encrypted user's details and personal identification number.
In one embodiment a user obtains the ticket by using their smartcard and personal identification number at a ticket retrieval station. Typically the ticket retrieval station generates the anonymous number based on the encrypted user's details and personal identification number, and retrieves the details of the ticket booking. Advantageously the personal identification number is required to book and retrieve the ticket, increasing security compared to systems where a user's input is only required for one of these actions. In one embodiment the booking is for a travel ticket. Typically the travel ticket is a flight ticket.
In one embodiment the ticket retrieval station is capable of creating and/or printing a boarding pass. Typically the boarding pass is electronic and stored in a travelling database.
In a further aspect of the invention, there is provided a system for booking a ticket comprising:
a ticket provider's website configured for allowing a user to book a ticket; a card reader for reading a user's details from an electronic smartcard when a ticket booking is requested;
input means for setting a personal identification number;
processing means for generating an anonymous number based on said user's details and associating the anonymous number with the ticket booking
storage means for storing said anonymous number; and
a ticket retrieval station for reading the smartcard and generating the anonymous number such that the user can obtain the ticket; characterised in that the user's details are encrypted with said personal identification number as a secret key.

Detailed Description
With reference to Figure 1 , there is illustrated a schematic view of the apparatus used to book a ticket in accordance with an embodiment of the invention
A user accesses the website of a service provider such as an airline for booking an electronic ticket such as a flight by using a computer 10 or other platform. The website requests that the user selects which method should be used for the booking i.e. normal or electronic smartcard 13. For extra security the smartcard 13 is provided with a Physical Unclonable Function (PUF) 14 which requires a challenge-response for authentication. User's data is stored in the smartcard.
A card reader device 12 embedded with a PUF reader 1 1 can interact with the smartcard 13 and PUF 14 for authentication thereof. The airline website of also requests a personal identification number (PIN) from the user as another security features. A privacy engine in the user's computer produces an anonymous number based on the combination of encrypted user's data and PIN number. This anonymous number is used to link to the electronic ticket at the booking phase, and stored inside a booking database, thereby protecting the privacy of the user's data.
With regard to Figure 2, there is illustrated a schematic view of the apparatus used to retrieve a ticket in the form of an e-kiosk 16. The e-kiosk 16 generates an electronic boarding pass according to the anonymous number and travelling information inside the booking database.
The e-kiosk 16 requests that the user selects which method should be used for the booking retrieval i.e. normal or electronic smartcard. A user can therefore insert their smartcard 13 in the card reader device 15' equipped with PUF reader 1 Γ. The smartcard 13 is authenticated as before and the user then inserts their PIN so that the anonymous number can be recreated based on the combination of encrypted user's data and PIN number. The anonymous number is used to retrieve the electronic ticket and the electronic boarding pass is generated and stored with the user information inside a travelling database.
With further reference to Figures 3-9 the system used to book and retrieves a ticket is illustrated. A customer accesses 200 the ticket provider's website to buy a transportation ticket such as a flight ticket through a secured channel such as https. After the user has accessed the ticket provider's webpage, the web client module 109 inside the customer's computer is connected with the web server module 104 at the ticket provider's application server.
After the user selects 201 to buy and book e-ticket by using a smartcard (also referred to as e-card) as a method of transaction or payment 202, the system requests input 203 from the e-card to verify 205 the user. If there is no e-card the system reverts 204 to the normal method. The e-card stores the user's details in a memory 1 13.
The customer puts 206 the e-card with an embedded physically unclonable function 1 14 into a card reader with PUF reader 1 10 capability. The PUF reader 1 10 transmits 1 12 a signal to start 207 a challenge-response session between PUF device 1 14 in the e-card 210. If the e-card is found 208 to be valid, the card reader reads the user's data in the e-card 210 and transmits 1 1 1 the same to the user's computer. If not the session is ended 209.
A secured financial firm's website 102 is then provided for payment 21 1. The financial firm's website receives and validates 212 user's data for e-ticket payment from the e-card. If the data is found 213 to be valid, the financial firm's website proceeds with the e-ticket booking process 215. If not the session is ended 214. The ticket provider's website requests 216 the user to set and insert 217 a PIN number 107 for another element of security.
An anonymous number creator (ANC) website plugin 108 receives 218 the PIN number from user input and user's data from the e-card. The ANC module encrypts 219 the user's data 106 by using symmetric encryption with the PIN number 107 as the secret key. The anonymous number is created 220 based on the combination of encrypted user's data and PIN number 107.
The anonymous number is then sent 221 to the web server module. The web server module 104 receives 222 the anonymous number and invokes 223 the e-ticket retrieval module 105 to retrieve 224 the e-ticket from a ticketing database 100. The webserver module 104 provides 225 e-ticket, flight information and anonymous number to the e-ticket and anonymous number linker (EAL) module 103.
The EAL module 103 creates 226 a link between the anonymous number and the e- ticket. The linking data between anonymous number and e-ticket, and flight information are stored 227 in the booking database 101 . The booking process ends after all the related information is stored inside booking database 101. The next step starts after a customer goes 228 to the e-kiosk of the ticket provider to generate a boarding pass. The system inside the e-kiosk needs the customer to select 229 the transaction method i.e. normal electronic or e-card. If the user selects 230 e- card, the system requests 232 input from the e-card to verify the user, otherwise the system reverts 231 to the normal method. The customer then puts 233 the e-card with PUF 1 14 into a card reader with PUF reader 1 19 capability.
The PUF reader 119 starts 234 a challenge-response session with the PUF device 1 14 in the e-card. If the e-card is found 235 to be valid, the card reader reads 237 the user's data in the e-card and transmits 1 18 the same to the kiosk. If not the session is ended 236. The subscriber's e-kiosk then requests 238 the user to insert 239 the PIN number 122 which was previously set by the user at the booking phase.
The anonymous number creator (ANC) application 121 receives 240 the PIN number 122 from the user input and user's data from the e-card. The ANC module encrypts 241 user's data 120 by using symmetric encryption and it uses the PIN number as the secret key 241. The same anonymous number as before is created 242 based on the combination of encrypted user's data and PIN number. The anonymous number is then sent 243 to the e-ticket and data retrieval module 124 to retrieve and verify 244 the anonymous number with flight information inside the booking database 101. If the anonymous number is found 245 to be valid, the e-ticket and data retrieval module 124 retrieves 247 e-ticket and flight information from the booking database 101 and sends it to the electronic boarding pass generator (EBG) 123. If not the session is ended 246. The EBG 123 generates 248 an e-boarding pass according to e-ticket, flight information and user's data from the e-card. The EBG 123 then creates 249 link information between e-boarding pass, flight information and user's data. Finally, the EBG 123 stores 250 the e-boarding pass, flight information and user's data into a travelling database 125.
It will be appreciated by persons skilled in the art that the present invention may also include further additional modifications made to the device which does not affect the overall functioning of the device.
