Internet of Things

The Internet of Things (IoT) refers to a network of physical devices, vehicles, appliances, and other physical objects that are embedded with sensors, software, and network connectivity, allowing them to collect and share data.

IoT devices—also known as “smart objects”—can range from simple “smart home” devices like smart thermostats, to wearables like smartwatches and RFID-enabled clothing, to complex industrial machinery and transportation systems. Technologists are even envisioning entire “smart cities” predicated on IoT technologies.

How Does The Internet of Things Work?

IoT devices will typically use one or more sensors to gather information. The type of sensor and the data it records will depend on the use case. For example, in healthcare one example of IoT use is an electrocardiogram array that records a patient’s sinus rhythm and heart rate.

You then have a software layer that provides data analytics and turns that raw sensor data it into something useful. In the electrocardiogram example, the software would look for signs of arrhythmia, an indicator of an underlying health issue.

Security, privacy, and safety concerns about the Internet of Things

A major concern for the IoT is the ability to build in adequate security protections. Hackers have already breached video systems, Internet-enabled baby monitors, medical devices, and even automobiles, and they have broken into corporate networks via unprotected IoT devices.

Data privacy and personal privacy are also important considerations. Inadequate security can lead to lost, stolen, or incorrectly used data, including private health and financial information. Connected devices and systems—along with data stored in the cloud—increase the number of vulnerability points..

Also that year, criminals broke into a casino, stealing a large amount of data, through an inadequately protected “smart” fish tank, whose Internet capabilities allowed its temperature, salinity, and food distribution to be controlled remotely but which also left the casino’s data system vulnerable to attack.

Why do connected devices need to share data?

An argument has been raised that only because something can be connected to the internet doesn’t mean it should be, but each device collects data for a specific purpose that may be useful to a buyer and impact the wider economy.

Within industrial applications, sensors on product lines can increase efficiency and cut down on waste. One study estimates 35 per cent of US manufacturers are using data from smart sensors within their set-ups already. US firm Concrete Sensors has created a device that can be inserted into concrete to provide data on the material’s condition, for instance.
