Re: Another 007 scheme ?
I designed a covert comms channel based exactly on this principle
what that guy is doing two desks back, holding his smartphone at their back while not moving at all for over an hour not moving , much, for an hour or two
but not for an office situation, just exfiltrating data across a national border or similar
relied on a few keen anglers and the usual PVdF piezo-acoustic transducers, possibly fish/bait shaped
I wonder if it was ever used (stego digital acoustic monitoring of all waterways surely IS implemented chaps?)
