•
the spectrum of insight, coving the five-phase data flow in real time (in motion,
early life, in rest and archive) and where data is processed at the point of
collection in real time all the way to where archived data is used for modelling
and analysis.
A3 Characteristics of systems and services that make up the IoT
•
The general characteristics of IoT systems and services:
o
risks, including security threats, e.g. hacking of connected cars allowing the
intruder to operate a vehicle remotely and the extraction of names and
financial account numbers from contactless payment services without
authentication from the owner
o
ethical and privacy considerations, including public and professional attitudes,
opinions and behaviours towards IoT and a reduction of low-skilled
employment opportunities
o
local legal considerations, e.g. use of data collected without consent and
cybercrime and data protection
o
sustainability considerations, e.g. power requirements, recycling and reuse of
components
o
benefits, including energy efficiency, e.g. transportation and in buildings,
productivity gains, e.g. optimisation of processes in manufacturing, and
agriculture, e.g. disease control and water use.
•
Understanding the technical characteristics of IoT systems and services:
o
low mobility when a device has low or no mobility during its lifetime or mobility
during a specific region. It often applies to systems and/or devices with specific
functions, e.g. payment, metering, point-of-sale kiosks or remote maintenance
o
time controlled, where data is exchanged at certain predefined time periods
and most applications have uses of time control
o
monitoring to detect events or actions rather than the security of the device
o
low power consumption, including extremely low consumption over long
periods of time, infrequent user interactions and no constant power sources
o
location-specific trigger, including waking the device in a specific area or
location.
