Intermediary Decentralized Computing and Private Blockchain Mechanisms for Privacy Preservation in the Internet of Medical Things

Protecting patient data in the Internet of Medical Things (IoMT) is one of the major challenges facing healthcare organizations because of increasing threats to privacy and security. Although there are many existing protocols and solutions, such as Rivest–Shamir–Adleman (RSA) and El-Gamal cryptographies or centralized methods, that aim to protect data, they suffer from weaknesses such as slow performance or inability to handle large volumes of data. The issue of security in medical records has become an urgent need, and the use of centralized methods can expose them to single-point failure. In this paper, we present the efficient approach to securing patient information (EASPI), which depends on blockchain and integrates innovative techniques such as the advanced encryption algorithm (AES), reverse word frequency analysis (TF-IDF), Lemplel-Ziv-Welch (LZW), decision tree model (DTM), and naive Bayes classifier (NBC). EASPI seeks to improve the security of medical data by storing it encrypted and securely via blockchain technology, providing a high level of privacy and reliability. The experimental results indicate that the EASPI reduces the encryption execution time to 0.2 ms and th
