2019-02-13 Wednesday - Homomorphic Encryption

An interesting discussion arose in the last week, which introduced me to the concepts of using Homomorphic Encryption in machine learning solutions.

"Fully  homomorphic  encryption  (FHE)  has  been  called  the  “Swiss  Army  knife  of  cryptog-raphy”,  since  it  provides  a  single  tool  that  can  be  uniformly  applied  to  many  cryptographicapplications.  In this tutorial we study FHE and describe its different properties, relations withother concepts in cryptography, and constructions.  We briefly discuss the three generations ofFHE constructions since Gentry’s breakthrough result in 2009,  and cover in detail the third-generation scheme of Gentry, Sahai, and Waters (GSW)"

2018-08-06 Monday - GDPR and Blockchain Privacy Implications

Some preliminary reading I'm doing...

Blockchain Technology and the GDPR - How to Reconcile Privacy and Distributed Ledgers

Blockchains and Data Protection in the European Union

• Max Planck Institute for Innovation & Competition Research Paper No. 18-01
• https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3080322
• "This paper examines data protection on blockchains and other forms of distributed ledger technology (‘DLT’). Transactional data stored on a blockchain, whether in plain text, encrypted form or after having undergone a hashing process, constitutes personal data for the purposes of the GDPR. Public keys equally qualify as personal data as a matter of EU data protection law. We examine the consequences flowing from that state of affairs and suggest that in interpreting the GDPR with respect to blockchains, fundamental rights protection and the promotion of innovation, two normative objectives of the European legal order, must be reconciled. This is even more so given that, where designed appropriately, distributed ledgers have the potential to further the GDPR’s objective of data sovereignty. "
