Abstract

This paper explores the innovative fusion of blockchain technology and digital twin frameworks to fortify personal security in an increasingly interconnected world. In the domain of personal security, the integration of blockchain and digital twin technologies presents a resilient and transparent solution. The digital twin serves as a virtual replica of an individual’s identity and surroundings capturing intricate details in real time. By incorporating blockchain’s decentralized ledger, a secure and tamper-resistant record is maintained ensuring the integrity and authenticity of personal data within the digital twin. This synergy establishes a trustworthy foundation for identity verification safeguarding against unauthorized access and identity theft. Blockchain’s cryptographic principles enhance data integrity preventing malicious alterations to the digital twin. Smart contracts, embedded within the blockchain, facilitate secure transactions and interactions offering a decentralized framework for personal security applications. This not only empowers individuals with greater control over their digital identities but also mitigates the risks associated ...
