Abstract

A system for toll payment by electronic cash identifies an electronic purse and effects value transfer over a communication system without stopping the mobile (vehicle or person). Mobile identity MID is temporarily correlated with purse identity PID and one or another identity is erased on satisfactory or non-satisfactory completion of the transaction thereby allowing non-payers to be pursued while preserving the principle of anonymity.

Claims

1. A system for toll payment by mobiles comprising:

a communication device and an electronic purse coupled to the device located on each mobile, the electronic purse being part of an electronic cash system;

localiser means for localizing the communication devices;

a remote communication system for communicating with the mobile communication devices to effect toll payments by exchanging cryptographically secure value transfer messages;

means for obtaining a mobile identifier identifying the communication device or the mobile carrying the electronic purse;

means for correlating temporarily the mobile identifier with an identifier for the electronic purse; and

means for (a) discarding the mobile identifier if the toll payment transaction is completed satisfactorily or (b) discarding the purse identifier if the toll payment transaction fails.

2. The system as claimed in claim 1 wherein the remote communication system is a cellular telephone system and each communication device is a mobile telephone and the mobile identifier is the mobile telephone identifier.

3. The system as claimed in claim 2, wherein the localiser means identifies the presence of a mobile within a general area.

4. The system as claimed in claim 2, wherein the localiser means comprises a radio or satellite location system.

5. The system as claimed in claim 2 wherein the cellular telephone system is a GSM system including personal smart cards and the mobile identifier is the personal identifier in the GSM system.

6. The system as claimed in claim 5, wherein the localiser means identifies the presence of a mobile within a general area.

7. The system as claimed in claim 5, wherein the localiser means comprises a radio or satellite location system.

8. The system as claimed in claim 1 wherein the mobile identifier is an optical image, the means for obtaining which is a camera associated with the location means.

9. The system as claimed in claim 8, wherein the localiser means comprises an observation station associated with a channelling system for the mobiles whereby mobiles may be individually located in channels as they pass the observation station.

10. The system as claimed in claim 8, wherein the localiser means comprises a radio or satellite location system.

11. The system as claimed in claim 1, wherein the localiser means comprises an observation station associated with a channeling system for the mobiles whereby mobiles may be individually located in channels as they pass the observation station.

12. The system as claimed in claim 1, wherein the localiser means identifies the presence of a mobile within a general area.

13. The system as claimed in claim 1, wherein the localiser means comprises a radio or satellite location system.
