Abstract

The invention concerns a method for editing a ticket providing access to a product or a service with specific duration and or expiry date, characterised in that it comprises a step of recording (EIA) on the ticket an authenticating information encrypted at least partly in accordance with a specific encryption law.

Claims

1. A method for editing tickets providing access to a product or service with specific duration and or expiry date, said method comprising for each ticket, the steps of:

generating a first part of authentication information by encrypting one parameter relative to the validity of the ticket with a key algorithm, wherein said one parameter is printed on the ticket, and wherein said one parameter is selected from the group consisting of the end of parking time, the start of the parking time, the issue date of the ticket, and the validity date of the ticket; and

recording on the ticket the authentication information.

2. A method according to claim 1, further comprising the step of generating a second part of the authentication information which is a unique identification number of the ticket, distinct from the one parameter relative to the validity of the ticket.

3. A method according to claim 1, wherein said key algorithm is modified every predetermined period of time.

4. The method according to claim 3, wherein said key algorithm is modified every fortnight.

5. A method according to claim 1, wherein the key algorithm is modified after a predetermined number of produced tickets.

6. The method according to claim 5 wherein the key algorithm is modified every 1,000 produced tickets.

7. The method according to claim 3, wherein the tickets are produced by a parking meter;

and

wherein the key algorithm is modified by reprogramming the parking meter.

8. The method according to claim 5, wherein the tickets are produced by a parking meter;

and

wherein the key algorithm is modified by reprogramming the parking meter.

9. The method according to claim 1, wherein the tickets are produced by a parking meter;

and

wherein the authentication information comprises a third part, which consists in a signature of the parking meter.

10. The method of claim 9, wherein the third part is specified according to the first part and the second part.

11. The method according to claim 2, wherein the unique identification information is an increment starting from the editing of the previous ticket.

12. The method according to claim 2, wherein the unique identification information is a transaction number specified by an external system of transaction authentication.

13. The method according to claim 1, wherein the first part of the authentication information includes a graphic device whose form and/or color is specific according to the one parameter relative to the validity of the ticket.

14. The method according to claim 1 wherein the recording consists in printing on the ticket.

15. A system for editing tickets, comprising a means for implementing the method according to claim 1.
