A whole range of devices, from radio frequency tags to smart cards and mobile phones, will be managed over the internet, explained the ITU, bringing about what it calls an "internet of things".
But the ITU warned that such a view assumes that each technology is working under a common standard, something that will be hard to achieve.
Privacy is another concern, as is the fear that such a network of "things" could have unpredictable ramifications.
The suggestion also raises the question of personal responsibility when a device makes a decision for its owner. This has already led to questions over traders who use automated selling systems that have caused market crashes.
The ITU is calling for more debate about issues of informed consent, data confidentiality and security.
"Unless there are concerted efforts involving all government, civil society and private sector players to protect these values, the development of an 'internet of things' will be hampered, if not prevented."
