Trusted Driver Technology
A national TDP road-pricing system is clearly complex, involving many sub-systems. The Trusted Driver technology is designed to provide one element: it specifies the information flow in such a way as to provide privacy to the driver.
This section of the web site provides an overview of the technology. It does not go into detail. For further information, please contact us.
We first present the scheme that is described by the Department for Transport's Road Pricing Feasibility Study and explain how this system leaves the motorist vulnerable to snooping by hackers and by government agencies. Indeed, key parts of the privacy model MUST be violated in order to produce itemised bills.
We then present the Trusted Driver model and show how it preserves the driver's privacy.
Further tabs in the Technology navigation bar above provide additional information. A live demo provides a simulation of the Trusted Driver scheme, using a Google Maps mashup, and shows flows of data between the various players, demonstrating the privacy provided by the Trusted Driver model.
