Abstract
Where sensitive information forming part of a transactional flow application is required to be sent over an open network such as the Internet, for example from a World Wide Web site, a time stamp and a location stamp are included in a request for such information from a user. The time stamp carries the time at which a previous page in the application was sent to the client and the location stamp carries the client address as provided for that previous page. Preferably the stamps are encrypted and are thus protected at the user location.
