Abstract
A portable storage device, eg. a smart card, is capable of securely storing data to be accessed only by authorised users, and of securely transferring data to another portable storage device under the control of a transfer device. The security of the data exchange is independent of the security of the transfer device. Thus data may be freely exchanged between portable storage devices by authorised users without authorisation from any other source.
Description
Special functions for Portable Storage Devices
The invention relates to secure Portable Storage Devices with special new functions which are additional to those described in Patent Specification Numbers 1 554 196, 1 505 715, 1 543 601 and 1 543 602.
The primary use of portable storage devices, of which smart cards and smart modules are good examples, is related to security whether for on-line access authorisation or tamperproof resource credit storage. In existing systems, data is loaded and unloaded by a trusted transfer device. Such transfer devices are however expensive and in order to limit liability they often have to obtain on-line authorisation from a central trusted device. The cost of the communication and the delays imposed on the authorisation often place unacceptable overheads on the transaction.
If secure portable storage devices are to represent the practical analogue of the wallet then transfers between portable storage devices must be possible without reference to an external trusted device. For this functionality to be provided without impairing the security inherent in and demanded from a secure portable storage device, certain features must be added to the system software within the device.
According to the present invention there is provided a method whereby one portable storage device may securely exchange data with another portable storage device under the control of a transfer device without reliance on the trustworthiness of the transfer device.
The resource/data transfer must be certain to take place between the two authorised parties, any possibility of the data being lost in a third system must be precluded.
Therefore, Operating System routines have been introduced to open direct communication from one portable storage device to another. The process is set up by a third system which has no involvement in the transfer. The third system merely acts as a portable user interface to the two portable storage devices.
An example of the practical use of the system is as follows:
A shopkeeper has a till incorporating a reader in which the shopkeeper's smart card
is placed. A further reader accepts the customer card and purchases are registered
as in a conventional till with the transfer authorisation being by password. Funds
are collected on the shopkeeper's card which may be redeemed at the bank or via
an on-line terminal to a bank or spent at other tills in the same way. The
shopkeeper's card is functionally identical to the customer's card except for
password and identity.
A car park may be equipped with a series of low cost readers connected to a single
transfer device containing a collection portable storage device. Individuals who
may have reserved their parking place in advance or those entering on an ad-hoc
basis, may pay for their parking using their personal portable transfer device. This
not only entails the transfer of electronic resource credit units but also data on the
user and the vehicle itself. These together with timing information already known
could allow statistics on usage to be collected and analysed in an effort to improve
future service.
Claims (3)
1. The principle of secure data exchange between one portable storage device and another without authorisation from a third system.
2. A system in accordance with claim 1 containing software routines which permit and facilitate direct communication between portable storage devices via their respective communication ports.
3. A system in accordance with claim 2 where such routines enable secure transfers without reference to a third device.
