This information could be used to gauge your needs as a consumer or as information for advertising agencies. Information such as the number of people, their location, body size, heartrate and even their phone passwords has been harvested using AI on these WiFi signals. Recent work has applied Artificial Intelligence (AI) to study these WiFi blockages and harvest information about people in the room. In the same way that light is blocked and reflected for our eyes to observe, WiFi signals are also blocked and impeded by people’s bodies. WiFi sensing works much like a flashlight which you can shine into a room. With increased IoT penetration, public spaces will see the application of WiFi sensing, an emerging technology which has shown the ability to monitor and track people’s movement and behaviour using passive WiFi signals from commodity devices.
This event has created much-needed discourse in parliament around privacy rights and increased protection for consumer data, however, lawmakers are in a scramble to keep up with the rapid development of new, dangerous technologies. Facebook had unethically harvested user data from millions of users, which was used by Cambridge Analytica to formulate political advertising strategies.

Unfortunately, services offered under the guise of customer satisfaction often have underlying motivations, such as the collection of user data for commercial gain.
According to Grandview Research, the IoT in retail sector has a current annual growth rate of 26 per cent, and brick and mortar shops are increasingly being transformed into digital stores with WiFi and internet interfaces to improve customer experience. As Australia encounters a rapid proliferation of Internet of Things (IoT) devices, it is easy to see that we are becoming a more connected nation.
