Blockchain and Onion Routing-Based Secure Data Management Framework for Healthcare Informatics

Healthcare is undeniably a paramount concern for both individuals and nations alike. Its significance extends beyond just individual well-being, as the state of healthcare plays a pivotal role in the overall growth and stability of a nation’s economy. Recognizing this, industry and academics have embarked on various pioneering initiatives aimed at improving the quality of healthcare decisions and services. These efforts have remarkably transitions in healthcare frameworks, progressing from Healthcare 1.0 to Healthcare 5.0. Nowadays, wearable devices make the healthcare analysis of any individual easy. Doctors/hospitals can take the data, analyze it and suggest the diagnosis. But, this is not easy as we think. It is because of security issues where attackers can tamper with the wearable device message before reaching the concerned doctor. The modified message can misguide the doctor with an accurate diagnosis. This leads to a more severe cause for the patent and can endanger the patient’s life. Existing frameworks are mainly focusing on traditional cryptographic and blockchain solutions, which offer some level of security but no anonymity. Motivated by this, we proposed an artificial intelligence (AI), blockchain and onion routing-based secure and anonymous healthcare data management framework for wearable devices in this paper. Onion routing offers high security and anonymity with multi-layer encryption, whereas AI is used to distinguish malicious non-messages from malicious ones. Blockchain is used to authenticate the intermediate nodes of the onion network.
