Blockchain-based Decentralized Identity Management for Privacy-preserving over 6G Smart Healthcare

Abstract

6G Smart healthcare services provide high-quality healthcare services using individuals’ electronic health records for the user. However, since electronic health records contain users’ personal information, they are a major target for security threats such as hacking and data leakage. If a user’s information leaks, it can be used for various crimes and cause direct damage to the user. Therefore, a method that can safely preserve users’ privacy in 6G smart healthcare is required. In this paper, we propose blockchain-based decentralized identity management for privacy-preserving in a 6G smart healthcare system. In the proposed system, users can create and manage their own identities using their attributes. We simulate the proposed system on the Ethereum network and show that our system has excellent efficiency.
