Abstract

A method and system for purchasing and authenticating an electronic ticket has a computer for receiving a ticket request from a user system and generating electronic ticket image data including a ticket identifier in response to the request; encrypting the generated electronic ticket image data and sending them to the user system; forwarding the encrypted electronic ticket image data from the user system to an associated user wireless communication terminal; which decrypts the encrypted electronic ticket image data and displays it on the screen of the terminal; and a computer which checks the validity of the ticket by reading the electronic ticket image data displayed on the screen of the terminal.

Claims

1. Method for purchasing and authenticating an electronic ticket, comprising the steps of:

a) receiving a ticket request from a user system and generating an electronic ticket image data including a ticket identifier in response to the request;

b) encrypting the generated electronic ticket image data and sending them to the user system;

c) forwarding the encrypted electronic ticket image data from the user system to an associated user wireless communication terminal;

d) decrypting the encrypted electronic ticket image data and displaying them on the screen of the terminal; and

e) checking the validity of the ticket by reading the electronic ticket image data displayed on the screen of the terminal.

3. The method of either claim 1 or 2, wherein receiving a ticket request from a user system is performed over the Internet.

4. The method of either claim 1 or 2, the wireless communication terminal may be either a personal digital assistant(PDA) or mobile telephone.

6. The method of claim 1 or 2, wherein checking the validity of the ticket includes extracting the ticket identifier from the electronic ticket image.

11. A computer program product, comprising a computer readable medium in which program instructions are stored, which instructions, when read by a computer, cause the computer to perform the steps of method for purchasing and authenticating an electronic ticket according to any one of claims 1-6.

2. Method for purchasing and authenticating an electronic ticket, comprising the steps of:

a) receiving a ticket request from a user system and generating an electronic ticket image data including a ticket identifier in response to the request;

b) encrypting the generated electronic ticket image data and sending the encrypted electronic ticket image data to a user wireless communication terminal associated with the user system;

c) decrypting the encrypted electronic ticket image data and displaying them on the screen of the terminal; and

d) checking the validity of the ticket by reading the electronic ticket image data displayed on the screen of the terminal.

5. The method of claim 2, wherein sending the encrypted electronic ticket image data to a user wireless communication terminal is performed over the wireless communication networks.

7. System for purchasing and authenticating an electronic ticket, comprising:

a) means for receiving a ticket request from a user system and generating an electronic ticket image data including a ticket identifier in response to the request;

b) means for encrypting the generated electronic ticket image data and sending them to the user system;

c) means for forwarding the encrypted electronic ticket image data from the user system to an associated user wireless communication terminal;

d) means for decrypting the encrypted electronic ticket image data and displaying them on the screen of the terminal; and

e) means for checking the validity of the ticket by reading the electronic ticket image data displayed on the screen of the terminal.

9. The system of either claim 7 or 8, further comprising store means for storing the information on the generated ticket including the ticket identifier.

8. System for purchasing and authenticating an electronic ticket, comprising:

a) means for receiving a ticket request from a user system and generating an electronic ticket image data including a ticket identifier in response to the request;

b) means for encrypting the generated electronic ticket image data and sending the encrypted electronic ticket image data to a user wireless communication terminal associated with the user system;

c) means for decrypting the encrypted electronic ticket image data and displaying them on the screen of the terminal; and

d) means for checking the validity of the ticket by reading the electronic ticket image data displayed on the screen of the terminal.

10. The system of 9, wherein the means for checking the validity of the ticket further comprises:

means for extracting the ticket identifier from the electronic ticket image data; and

means for checking if the extracted ticket identifier is stored in the store means.
