Security and Privacy of Patient Information in Medical Systems Based on Blockchain Technology

Abstract: The essence of “blockchain” is a shared database in which information stored is un-falsifiable, traceable, open, and transparent. Therefore, to improve the security of private information in medical systems, this article uses blockchain technology to design a method to protect private information in medical systems and effectively realize anti-theft control of private information. First, the Patient-oriented Privacy Preserving Access Control model is introduced into the access control process of private inform… Show more

“…With the recent growth in the blockchain territory and the rise of decentralized finance (DeFi) and cryptocurrencies, the occurrences of 51% attacks on different blockchains have seen a dramatic increase in recent years. In addition to that, the relevance of blockchains has been on a significant rise in the recent decade, with many solutions tomodern problems being based on the blockchain technology [ 42 , 43 ]. Smaller blockchains with a low hashrate are more vulnerable to such attacks, as a lower hashrate means less processing power is needed to validate and add transactions to the blockchain.…”
