The total installed base of Internet of Things (IoT) connected devices is projected to amount to 75.44 billion worldwide by 2025, a fivefold increase in ten years. The IoT, enabled by the already ubiquitous Internet technology, is the next major step in delivering Internet’s promise of making the world a connected place.
What is the IoT?
The IoT describes the network of devices that are connected via the Internet. Being connected, such smart devices, which include smart home devices such as smart meters and smart locks, are able to share data among each other, providing benefits such as better quality of life and greater insight into business. The next generation mobile connection technology 5G, with a forecasted number of 1.3 billion subscriptions by 2023, would be a major boost for the application of IoT in everyday life.
Privacy/security concerns
Data privacy and security are among the major concerns with regard to IoT adoption. Once devices are connected to the Internet, they become vulnerable to possible security breaches in the form of hacking, phishing, etc. Frequent data leaks from social media raise earnest concerns about information security standards in today’s world; were the IoT to become the next new reality, serious efforts to create strict security stands need to be prioritized.
