  • (GDPR): a Delphi Study
    PEER Reviewed RESEARCH OPEN ACCESS ISSN Online: 2516-3957 ISSN Print: 2516-3949 https://doi.org/10.31585/JBBA-1-1-(4)2018 Blockchain and Privacy Protection in Case of The European General Data Protection Regulation (GDPR): A Delphi Study Simon Schwerin Berlin School of Economics and Law, Germany Correspondence: [email protected] Received: 28 March 2018 Accepted: 30 March 2018 Published: 18 April 2018 Abstract The present work deals with the interrelationships of blockchain technology and the new European General Data Protection Regulation, that will be intact after May 28th, 2018. The regulation harmonizes personal data protection across the European Union and aims to return the ownership of personal data to the individual. This thesis, therefore, addresses the question how this new technology that is characterized by decentralization, immutability and truly digitized values will be affected by the strict privacy regulation and vice versa. The aim of this work is to clarify whether blockchains can comply with the new regulation on the one hand and to identify how blockchain could support its compliance, on the other hand. The questions are validated through an extensive literature review and are further investigated by using a Delphi study that asks a panel of 25 renowned experts to find opportunities, limitations and general suggestions about both topics. In addition, a framework is proposed to support the assessment of privacy and related risks of blockchains. As a result, it becomes apparent that blockchains can become more privacy friendly and comply with the regulation if an active dialogue between blockchain developers and regulatory authorities helps to strengthen their mutual understanding and work.

  • Secure Identity Management on the Blockchain
    Eötvös Loránd University Faculty of Informatics SECURE IDENTITY MANAGEMENT ON THE BLOCKCHAIN Adám Nágy Kwadjo Anobaah Nyante Assistant Professor at ELTE Msc. Security & Privacy Advanced Cryptography Andreas Peter Assistant Professor / Study Coordi- nator – Cyber Security & Safety at University Of Twente Zoltán Hattyasy Senior PM & Architect Mission Critical Systems at E-GROUP Budapest, 2018. Summary One major topical issue that has generated a lot of controversy in the cyber security land- scape is Secure Identity Management. So serious is this issue that many educationists and academicians have expressed varying concerns, proposals, and solutions about the subject. Traditional Identity Management solutions delegate trusted centralized organizations / multiple centralized agencies (service providers) and task them with securely storing the private data of users and providing these users with identity tokens such as ID cards, cer- tificates, login credentials, hardware, and passports. With these identity tokens, users can uniquely access resources and services from the respective service providers. This approach has resulted in four main classes of problems namely: Individual user problems, Infor- mation Sharing problems, Governmental information coordination problems, and Privacy problems. These problems are particular conspicuous in the banking sector when it comes to Know- Your-Customer Processes (KYC). It is expensive and time consuming to do the necessary background checks on customers and their transactions for compliance agencies. At the same time, these background checks have create severe privacy issues that need to be ad- dressed. In this research, Distributed Ledger Technologies (blockchain) are used to solve these major problems. A hybrid solution is proposed, which is a combination of: 1. A blockchain Gateway Solution, which supports legal compliance and traditional Identity Management features that require strong authentication.

  • Protection of Personal Data in Blockchain Technology
    Protection of Personal Data in Blockchain Technology An investigation on the compatibility of the General Data Protection Regulation and the public blockchain Amelia Wallace Department of Law Master’s Thesis, 30 HE credits Area: Law and Informatics Master’s Program in Law (270 HE) Autumn term 2018 Group mentor: Johan Axhamn Swedish title: Personuppgiftsskyddet i Blockkedjeteknik – En utredning om förenligheten av dataskyddsförordningen och den publika blockkedjan Abstract On 25 May 2018 the General Data Protection Regulation, GDPR, came into force in the EU. The regulation strengthened the rights of the data subjects’ in relation to the data controllers and processors and gave them more control over their personal data. The recitals of the GDPR state that it was the rapid development in technology and globalisation that brought new challenges for the protection of personal data. Private companies and public authorities where making use of personal data on an unprecedented scale in order to pursue their own activities. The protection should be technologically neutral and not dependant on the technique used. This leads to questions on whether the protection that is offered through the GDPR is de facto applicable on all technologies. One particular technology which has caught interest of both private companies and public authorities is the blockchain. The public distributed blockchain is completely decentralized, meaning it is the users who decide the rules and its content. There are no intermediaries in power and the transactions of value or other information is sent peer to peer. By using asymmetric cryptography and advanced hash algorithms the transactions sent in the blockchain are secured.

It promises to change the way people do their business, track their products, and manage their personal data. Though the concept of DLT was first implemented in 2009 as Bitcoin, it has gained significant attention only in the past few years. During this time, different DLT enthusiasts and commercial companies have proposed and developed several DLT platforms. These platforms are usually categorized as public vs private, general purpose vs application specific and so on. As a growing number of people are interested to build DLT applications, it is important to understand their underlying architecture and capabilities in order to determine which DLT platform should be leveraged for a specific DLT application.

We also describe some of the significant roadblocks that must be overcome to achieve the lofty potential of this industry movement. Blockchain is a simple concept that can be game changing as adoption increases and a supporting ecosystem is built. That said, it has the potential of disrupting many long-standing processes. Blockchain tends to be either over-hyped or totally dismissed by analysts and vendors because of their a vested self-interest. In contrast, we seek to provide a balanced, independent perspective for our enterprise clients. Throughout this report we address many aspects of blockchain technology. We start with some of the basics on the technology itself, provide five business reasons to at least evaluate blockchain, and we’ll share five roadblocks you may need to address. We’ll also share blockchain patterns that may help you discover opportunities in the context of your business needs and provide educational guidance.
