Intrusion Detection in Internet of Things (IoTs) Based Applications using Blockchain Technolgy

Data security plays an important role in the healthcare monitoring systems, where critical patient data is transacted over the internet especially through wireless devices, wireless routes such as optical radio channels, or optical fiber-related transport networks. In one way or the other every device is connected to internet and we address such things as internet connected things. As the network is moving towards wireless applications, the threat to attack is also becoming a crucial issue. These attacks can be identified through various intrusion detection techniques and some of which were discussed in the previous decades. The intrusion detection technique is used to identify the privacy breach in the network. Its main purpose is to detect the unauthorized access. Some of the systems or networks that need protection are part of wireless networks (Things connected to internet). Wireless network applications comprises of WLANs (Wireless Local Area Networks), WPANs (Wireless Personal Area Networks), ad hoc networks etc. Since digitization is taking place in each and every sector and so the threat to data also exist. In this article, we protect IoT based E-healthcare systems by using a novel concept called “Blockchain Technology”.
