- [Instructor] The second challenge that faces IoT
is privacy.
Having a large network of devices and applications,
IoT systems are designed to collect sensitive data
about their environment, and often times,
data related to people.
To help IoT systems ensure privacy,
cryptographic techniques can be used.
That enables sensitive data to be stored, processed,
and shared without having the information content
accessible by outside parties.
Another consideration is during the design process
of the IoT devices or systems.
This simply means the need to have a plan
to ensure that the IoT device itself
has the required privacy layers.
Regulations are also needed when collecting data
involving people.
This can be done by having fair and consistent rules
that help apply privacy and protection,
and transparency within the IoT ecosystem
in ensuring that personal information
is being protected by the collector.
Now, there had been many incidents involving privacy breach.
An example is with Yahoo!.
In 2016, the company first publicly announced
a privacy breach incident which it said took place in 2013.
Yahoo! announced that the actual figure
of user accounts exposed was 3 billion.
Yahoo! suffered a second attack in 2014.
Data was stolen from 500 million accounts,
including names, email addresses,
phone numbers, passwords and date of birth.
