I thought of something like that but then thought again of the most relaxed master/slave relationships where the slave is almost treated equally and the concept of their being no positive control over who is using the internet. If the master gives their slave the password, its not secure.<br/><br/>I was thinking of a hole-in-the-wall terminal like an ATM but which needs a fingerprint scan. Or even a retinal scan. I know we are heading off towards sci-fi there but then again those technologies are pretty much with us now and if there had been such an extreme social change I am sure technologies aimed towards master/slave security would have been developed much like cell phone technology has completely exploded in our world in the last 10 years. With a fingerprint scan or retinal scan a slave would have to go to far greater extremes to cheat the system than simply finding her masters passcode.<br/><br/>Monaco is under 2 sq km in area, so 4 or 5 SRCTs (Slave Roaming Control Terminals) in the entire principality would ensure that no-one lives more than a few hundred yards from one.<br/><br/>I might have mentioned earlier that the BAF sat-nav slave monitoring service is available remotely. The obvious place this would be used is on an owners phone, but a web browser service would also be available. I see this as a pay-per-use service rather than an app you buy/download and then have 24/7 free slave monitoring capability.
