Abstract |
The advancement of AI and IoT technologies has underscored the importance
of personal data protection, given the exponential increase in data volume. Traditional centralized data management systems are increasingly challenged to meet
evolving security demands, often hampered by a single point of failure that presents
significant risks. In contrast, distributed ledger technologies, such as blockchain,
propose a novel approach with their decentralized structure and inherent resistance
to tampering, offering a promising avenue for enhancing data security.
This thesis explores the potential of blockchain technology to enhance security mechanisms within existing environments. Blockchain’s distinct architecture
provides key advantages over traditional systems, especially in enhancing security without relying on a centralized authority. This is demonstrated through
the development of a prototype system on the Hyperledger Fabric Blockchain,
which introduces an innovative method for securing personal sensitive information. This system seamlessly integrates with the OAuth 2.0 framework, employing
blockchain-based tokens and smart contracts for robust identity management and
access control. It further establishes a Policy Decision Point and a Policy Enforcement Point, ensuring transparent and automated policy enforcement. It is
also complemented by a user-friendly RESTful API, illustrating the blockchain’s
capability to manage user identities and permissions effectively.
The insights from this research suggest a viable alternative to conventional data
management systems, contributing to a deeper understanding of the constantly
evolving security landscape. Through this investigation, the thesis aims to pave
the way for the development of more secure, scalable solutions that can effectively
address upcoming challenges.
