Blaž Podgorelec: @James - Daniel_Du_Seuil Daniel Du Seuil: Want more standardized interactions through VCs, VPs - slide 15 Daniel Du Seuil: Will need shared infrastructure, e.g., ledgers Daniel Du Seuil: Working on version 2, working with market to ensure right focus Kim Hamilton Duffy: https://drive.google.com/file/d/1qyK6IZKjklWFPx0oZyR_qk1um6TeRwze/view Erik's nickname? Lluís Alfons Ariño: Erik Van Zuuren Kim Hamilton Duffy: James -- he's not in irc now. Just call him Erik Erik Van Zuuren: overview of legal requirements with electronic identities - slide 17 Erik Anderson: Description of ESSIF VC Erik Anderson: Slide 18 Daniel Du Seuil: Overview of ESSIF vs eIDAS Daniel Du Seuil: Slide 19 Daniel Du Seuil: Overview of cross border interactions Daniel Du Seuil: The complete legal report on link ssi-eidas can be found at https://joinup.ec.europa.eu/collection/ssi-eidas-bridge Lluís Alfons Ariño: Slide 20 Daniel Du Seuil: Slide 20 - feature roadmap Daniel Du Seuil: For ESSIF under eIDAS Daniel Du Seuil: Slide 21 Daniel Du Seuil: We can provide more elaborate legal report Daniel Du Seuil: We will be sharing in the next month Lluís Alfons Ariño: Open for questions Kim Hamilton Duffy: Question about slide 16 Kim Hamilton Duffy: Verifiable credential hashes - how do they work with right to erasure, permanence. is a hash sufficiently de-identified. what tradeoffs did you make. what determinations did you make re: GDPR Daniel Du Seuil: Will share GDPR study. want to limit what can be traced back to individual. We don't put VC on ledger, just the hash, maybe with start and end date. doesn't show VC itself, just like a fingerprint Erik Anderson: Ongoing discussions re GDPR Erik Anderson: Looking at legal implications. might put pseudonyms for certain cases on ledger Erik Anderson: GDPR is a concern. bottom line we do put things on ledger but minimize correlation Nate Otto: Question about VC and DIDs on slide 17. what DID method is used and how id for individual is provisioned for individual Erik Anderson: Not cast in stone yet. we will allow users to create their own DIDs, and own wallets, but will put minimal requirements for DIDs. DIDs need to be unique and you must be able to show control. Will be used for authentication and we have minimal standards Erik Anderson: To meet legal requirements Erik Anderson: Exact format of DIDs are being fine tuned. Kim Hamilton Duffy: Anthony asked about VCs in XML to satisfy legal binding signatures. How can we help - can CCG express XML serialization to help you? Kim Hamilton Duffy: Maybe jsonLD sigs would be acceptable. what do you think we can do to help you. Erik Anderson: Yes, we can align work. Kim Hamilton Duffy: With PESC XML transcripts we may have use cases that need XML VC support. we've had discussions on mailing list. starting to understand it is all doable. wondering about overall priorities Erik Anderson: Would be great to collaborate. will have initial study available next week Kim Hamilton Duffy: In slide 17, W3C peer did is mentioned. is that a work in progress? are peer kids something you looked into and how will you use? Daniel Du Seuil: Peer dis are very interesting - less tracking, more secure, more privacy. following interactions. valuable concept to follow. Kim Hamilton Duffy: Reference on peer dids: https://www.slideshare.net/SSIMeetup/peer-dids-a-secure-and-scalable-method-for-dids-thats-entirely-offledger-daniel-hardman Kim Hamilton Duffy: @Blazp I will read it Blaž Podgorelec: @Kimhd thank you! Dominik Beron: Everything boils down to privacy. legal entities are less problematic than actual persons. peer dids aren Dominik Beron: Aren't necessarily stable. We are looking at it. Erik Anderson: Much easier to implement anywise DID but might have GDPR issues - don't want to allow correlations. if we correlate to a single number we will not get a good GDPR report. Erik Anderson: We think we might have to go to peer dids Erik Anderson: A single European number is dangerous. a verifiable id can be used with legal effect
