Cybersecurity Anomaly Detection: AI and Ethereum Blockchain for a Secure and Tamperproof IoHT Data Management

The Internet of Healthcare Things (IoHT) is an emerging critical technology for managing patients' health. They are prone to cybersecurity vulnerabilities because they are connected to the internet, primarily by wireless connections. This is a major concern, considering data privacy and security. Artificial intelligence (AI) models are excellent methods to detect and mitigate cybersecurity vulnerabilities. Since medical Information Technology (IT) is evolving and data privacy is a major concern with sensors generally, in healthcare IoT. The TON_IOT, Edge_IIoT, and UNSW-NB15 datasets were used in this study for assessment and implementation to solve the challenge using the chosen benchmark AI models with the integration of IPFS blockchain technology in order to decentralize and secure the data. Justifiable parameters were used to determine how efficient each technique is in predicting the best outcome. The results show the efficiency of the utilized models, particularly the Support Vector Machines (SVM). The TON_IoT dataset obtained 100% accuracy, the Edge_IIoT dataset obtained 98% accuracy, and the UNSW-NB15 dataset obtained 89% accuracy. The integrated blockchain technology in this model is applied for security purposes. Utilizing these techniques will proffer a secure and safe transmission of medical data. This study will generally provide important insight to other researchers in the healthcare field.
