Will Blockchain Guarantee Enough Security and Privacy of Internet?
According to the significant technological change that has occurred in the past decade, we can now be sure that the integration of innovative tools including blockchain, distributed ledger technology (DLT), and general data protection regulation (GDPR) standards are somehow sufficient and able to ensure the security and privacy of personal data in future Internet systems. Furthermore, is GDPR fully compliant with the EU-stated principle of "Do people need to maintain control of their personal data generated or processed within the disruptive technologies like blockchain and internet of things"?.
Apart from the initial request for consent, no prior control by the person concerned of the subsequent authorized or unauthorized use of his data is guaranteed and at most can only be verified in retrospect, for example with access to a database of all transactions of data certified by a blockchain technology. Examples of the application of new technologies to some use cases are GDPR compliance, informed consent management or denial and privacy in mobile apps, application to the food chain, energy balancing of electricity supply, mobile games, smart meters, tools for people with special needs, extraction, classification and encryption of document content and blockchain technologies.
