#IPEN event on “Secure Multi-Party Computation”

Today, EDPS organised an IPEN event hosted by Goethe University Frankfurt.

This edition's topic was "Secure Multi-Party Computation (SMPC)" was tackled by our panellists Ivan Damgård, Thomas Schneider, Riivo Talviste, Hossein Yalame, Thomas Loruenser, Idoia Gamiz Ugarte, Christian Rendel, Vincent Dunning, Liina Kamm, Giuseppe D’Acquisto.

Speakers have explored the intersection of legal, technical and ethical imperatives SMPC offers in a compelling framework for trust-by-design collaboration.

@Supervisor Wojciech Wiewiorowski closed the event reminding participants that the purpose of privacy-enhancing technologies goes beyond protecting data: it is about protecting people, enabling collaboration without coercion, innovation without exploitation and progress without surveillance.

A heartfelt thank you to our speakers, moderators, and to Goethe University Frankfurt for hosting this year's event.

One of my students alerted me to this example of SMPC in the real-world, at JPMorgan: "Prime Match is the first secure multiparty computation solution running live in the financial world"

It enables inventory matching - where buyers and sellers match to trade stocks without moving the market - but without revealing either party's buy/sell orders unless a match is found.

En dépit des apparences, #GMPC me semble être un client #MPD bien plus puissant et plus efficace que #Sonata.

#SMPC (#SailfishOS), quoique non maintenu hélas, est excellent aussi.
