EU Parliament publishes study on Blockchain and GDPR

In recent times, there has been much discussion in policy circles, academia and the private sector regarding the tension between blockchains and the European Union’s General Data Protection Regulation (‘GDPR’).

Whereas, the GDPR is based on an underlying assumption that in relation to each personal data point there is at least one the data controller, blockchains make the allocation of responsibility and accountability burdensome.

Further, although the GDPR is based on the assumption that data can be modified or erased where necessary to comply with legal requirements, blockchains, however, render the unilateral modification of data purposefully onerous in order to ensure data integrity and to increase trust in the network.

Blockchain startup JEDTrade launches privacy-protected data exchange platform

Singapore-based blockchain startup JEDTrade has launched Jupiter Chain – a consent-able data exchange platform that enables the use of data analytics without compromising on privacy.

Jupiter Chain allows blockchain technology to be put in the healthcare services ecosystem, where data privacy and security is crucial. It does so by encrypting users’ data and requiring consent before other parties can access the necessary information to conduct big data analytics projects.

How Microsoft Plan to Empower Users to Own and Control Personal Data

Microsoft presented a vast blockchain-related plan: a decentralized identity (DID) network built atop of the bitcoin network, which can potentially empower users all over the internet to take control over their personal data and content.

Titled the Identity Overlay Network (ION), the infrastructure lets users obtain control over their own data via the management of their Public Key Infrastructure (PKI).

DID allows users to control their own data and content — including login details and photos, which is not currently possible on most social media platforms that store such data on their private, centralized servers.

Once hailed as unhackable, blockchains are now getting hacked

We’ve long known that just as blockchains have unique security features, they have unique vulnerabilities. Marketing slogans and headlines that called the technology “unhackable” were dead wrong.

More and more security holes are appearing in cryptocurrency and smart contract platforms, and some are fundamental to the way they were built.

Together we can thwart the big-tech data grab. Here’s how.

Our lives, online and off, depend upon decentralising power on the internet, says the Guardian columnist John Harris.

As the year unfolds, pay attention to the people who are talking about a new, decentralised internet – AKA Web 3.0 – and the possibility of data being returned to the control of the people who generate it.

In Boston, the worldwide web’s founder, Tim Berners-Lee, is working on a new way of using the internet, called Solid. Then there are the possibilities bound up with the blockchain, the system of verification that sits under so-called cryptocurrencies. Startup called Fetch is developing what it calls decentralised artificial intelligence.

MEPs call for business GDPR ‘guarantee’ on using blockchain

Businesses should not begin using blockchain technology to process personal data until they can “guarantee compliance” with EU data protection laws, a committee of MEPs has said.

The Committee on Civil Liberties, Justice and Home Affairs (LIBE) said that businesses using blockchain must, in particular, be able to respect the rights of data subjects under the General Data Protection Regulation (GDPR) to the rectification and erasure of their data.

Private Blockchains Could Be Compatible with EU Privacy Rules

A joint study between Queen Mary University of London and the University of Cambridge concluded that, whilst challenging, it is theoretically possible for organizations to design blockchain applications that fully comply with recently implemented EU ‘General Data Protection Regulation’.

Due to innate aspects of blockchain technology, like the immutability and inability to retrospectively remove customer data recorded as such, the problems become obvious when it comes to creating a solution compatible with this European regulation.
