Why do you think a phone line has no chance of interception? Phone lines have been tapped for years. It is very easy to do, if you know how.
to intercept data transmission? I don't think so. I never heard of that happening.
It's been done. http://zdnet.com.com/2100-11-501418.html?legacy=zdnn By John Simons The Wall Street Journal Online September 30, 1999, 5:00 PM PT Morris and technicians at the FBI's engineering lab in Quantico, Va., worked together to draft the specifications for the device Morris wanted. It would need to do the reverse of what a computer's modem does. A modem takes digital data from a computer and translates it to analog signals that can be sent via phone lines. Morris's device would intercept the analog signals on Cantrell's phone line and convert those impulses back to digital signals so the FBI's computers could capture and record each of a suspect's keystrokes." I snipped only the relevant paragraph under fair use. The prototype unit cost U$70K in 1994. With Moore's Law, I'm sure the cost has gone way down. Jim -- The Toronto Linux Users Group.
