The Role of Blockchain Technology in Ensuring Correspondence Confidentiality and GDPR Compliance

ABSTRACT: The purpose of this research is to explore how blockchain technology can be leveraged to protect the confidentiality of electronic correspondence while adhering to the requirements of the General Data Protection Regulation (GDPR). As digital communication becomes increasingly prevalent, safeguarding sensitive information is essential, especially considering GDPR’s stringent data protection rules. This study aims to assess the advantages, challenges, and potential solutions related to using blockchain for securing correspondence. The research involves a comprehensive review of existing literature on blockchain technology and data protection, along with a comparative analysis of blockchain features and traditional methods for securing electronic communication. Case studies of current implementations of blockchain in various industries, such as finance and healthcare, are examined to identify practical applications and compliance strategies. Additionally, technical challenges, including scalability and the conflict between blockchain’s immutability and GDPR’s right to be forgotten, are analyzed. Theoretically, this study contributes to understanding blockchain’s role in enhancing data security and its legal implications under GDPR. It offers insights into the evolving landscape of digital privacy and the intersection of emerging technologies with regulatory frameworks. Practically, the research provides valuable recommendations for companies seeking to implement blockchain to secure communications, highlighting best practices and potential pitfalls. This study serves as a guide for organizations looking to align technology adoption with legal compliance, ensuring robust data protection while fostering innovation. Overall, the findings aim to inform policymakers, technology developers, and businesses on optimizing blockchain’s use for protecting correspondence confidentiality under GDPR.
