[liberationtech] On Accountability for Resilience with Blockchain

Dear member of the Liberation Tech mailing list,

Regarding acceptable secure data sharing for resilience, please let me briefly introduce a latest journal publication.
“Privacy-Enhancing Trust Infrastructure for Process Mining” proposes an application of cryptography with blockchain and smart contracts
by the example of biometrics and its usage in times of a disaster such as an earthquake.

Threats to a society and its social infrastructure are inevitable and endanger human life and welfare. Resilience is a core concept to cope with such threats in strengthening risk management. A resilient system adapts to an incident in a timely manner before it would result in a failure. This paper discusses the secondary use of personal data as a key element in such conditions and the relevant process mining in order to reduce IT risk on safety. It realizes completeness for such a proof on data breach in an acceptable manner to mitigate the usability problem of soundness for resilience. Acceptable soundness is still required and realized in our scheme for a fundamental privacy-enhancing trust infrastructure. Our proposal achieves an IT baseline protection and properly treats personal data on security as Ground Truth for deriving acceptable statements on data breach. An important role plays reliable broadcast by means of the block chain. This approaches a personal IT risk management with privacy-enhancing cryptographic mechanisms and Open Data without trust as belief in a single-point-of-failure. Instead it strengthens communities of trust.
