I wonder, can this technology be used to track people's whereabouts without their knowledge? For example, is there or could there be some NSA or other secret group back door whereby a tracing function may be activated via the internet?
This type of concern is already being tested for car systems, especially the radio systems used by luxury vehicles to monitor tire pressure. These specific systems tend to be the least secure, and can therefore be interecepted and read by someone nearby with the proper radio equipment.
Again, it sounds great, but I wonder if anyone can document any downsides from actual technical specs, and not just my Orwellian concerns.
