wseltzer: We have taken cards from yesterday into questions/statements and we're going to do dot voting on those... Kaliya will explain what we're doing next.
17:08:14 [manu]
wseltzer: Great agenda of additional talks/breakouts - exploring cultural perspectives, avoiding mistakes/minefields, breakouts discussing ideas, one of our goals it to help W3C figure out what we should do next.
17:08:27 [Mitja]
Mitja has joined #auth-id

17:09:01 [manu]
wseltzer: A key takeaway here becomes the next directions of what we'd like to collectively do next with all of this input.
17:09:39 [manu]
wseltzer: Lots of place for discussion in the roadmap, where we see the future and how to get there. We wrap up at 4pm today so folks can catch flights.
17:10:56 [manu]
wseltzer: I heard lots of great ideas and still lots of tension, concerns from folks focused on authentication that the identity isn't necessarily tied into authentication, concerns on identifiers (work being characterized wrongly, misunderstood) - if we're not looking at the right use cases, people come to different conclusions. We have time to work out differences in understanding, where is the agreement on the components of the stack?
17:11:20 [manu]
wseltzer: One outcome could be that we're trying to solve different problems, perhaps the technologies can coexist... we can offer insights to one another even if we're not working on the same piece of the problem.
17:11:52 [manu]
wseltzer: If we have issues with things others are working on - let's focus on constructive criticism, how can we all help to make the Web work better by building the right components around authentication and identity.
17:12:05 [manu]
Topic: Dot Voting on concerns and potential work items.
17:12:39 [manu]
Kaliya: We took output from conversation yesterday and crystalized them into some statements and put them on these forms.
17:12:59 [manu]
Kaliya: This is what the form looks like -- https://mit.webex.com/wbxmjs/joinservice/mtg/4e2f2c8c6aa2499fa4ff57e9e961581e?siteurl=mit&token=QUhTSwAAAARf3CNiSOA6s0HZ3erSbDBOP66rOlYCkn5W7aVxIveavX38e6v4v69VBCfgpENyvFVQSicO77PRbxUj8ULyazR0saTn9WaL%2BsFLlct6mYbYIKS2tGVk%2B0dpO%2FVA%2FxN5OlqHo05BvR1oGcR9ZJ%2BV9FpYjl96PBCjjqgN%2FXFT8bt4df2qFGns%2FHVmEwxreObvVxc%3D&userName=Manu%20Sporny&userEmail=msporny%40digitalbazaar.com&CSRF=9e99ffe4-85ca-46c2-bd28-17a6b6b8ee10&t

17:14:06 [manu]
achughes: Do we vote on all cards?
17:14:22 [manu]

slide 5
17:57:02 [manu]
Takashi: In ecommerce - in B2C - Amazong is close to Rakuten.
17:59:08 [manu]
Takashi: There are a number of fragmented identity platforms iN Japan.
17:59:25 [manu]
Takashi: Also, differnet payment methods.
18:00:00 [manu]
slide 7
18:00:23 [manu]
Takashi: Big Japanese companies have siloed solutions - six big companies - user has to know timetable... but just redirects to companies website.
18:02:06 [manu]
Takashi: Driving license has a dominant position in Japan... as an identity mechanism.
18:02:30 [wseltzer]
slide 9
18:02:38 [manu]
Takashi: Japanese government want to expand usage of "My Number" card for Japanese Social ID System... but most Japanese people don't use this card - only 10%.
18:05:21 [manu]
Takashi: We have a strong need for loose ID federation in Japanese Market...
18:05:35 [manu]
Slide 10
18:06:13 [manu]
Takashi: Large companies seem to want to take a dominant position on Social ID...
18:06:26 [manu]
Takashi: Governments seem to want Drivers license style approaches.
18:06:44 [manu]
Takashi: To achieve this, we need a scheme for DIDs and Self Sovereign identity especially consent management.
18:07:03 [manu]
Takashi: Thank you for your attention.
18:07:40 [manu]
MikeJones: Mike Jones from Microsoft, I know that Yahoo Japan and KDDI implement OpenID Connect. Are they using that to interoperably login at other Japanese sites, or is it mostly silos even though they are using that federation protocol?
18:08:26 [manu]
Takashi: Interop is not so great, in Japan, every company uses Social ID using Yahoo, ??, Facebook, and NTTDoCoMo...
18:09:00 [manu]
Topic: Automatic Identification Standards
18:09:14 [manu]
Slides -- https://docs.google.com/presentation/d/1hhcDys1nrHtBeAX89RQiWvYWB4bwojVOKH0aIaPXaIM/edit#slide=id.g49d4bd67a0_3_65
18:09:26 [manu]

shigeya: you know about bar codes (slide: bag of mints -- comes from GS1)
18:10:49 [manu]
shigeya: GS1 - they do the UPC - GS1 has a database...
18:10:57 [tomj]
tomj has joined #auth-id
18:11:01 [manu]
shigeya: GS1 standards - identify, capture, and share - slide 16
18:11:03 [manu]
Slide 16
18:11:52 [manu]
shigeya: There are multiple formats to identify, capture, and share... barcode is only one of them, can be expressed in URLs.
18:12:54 [manu]
shigeya: GS1 has identification keys - domains... trade items (GTIN), logistics (SSCC), Assets (GIAI), and locations (GLNs)

18:14:35 [manu]
shigeya: Companies assign GLNs to locatins like factories... examples of GS1 identifiers.
18:14:57 [manu]
shigeya: These are all expressible as URNs... urn:epc:id:...
18:15:11 [manu]
shigeya: These are not DIDs, but they kind of look the same, different domain.
18:15:35 [manu]
shigeya: There are also physical representations - barcodes, RFID, there are different formats/syntaxes.
18:16:28 [manu]
shigeya: So let's look at applications... GS1 Lightweight Messaging Standard for Verification... RESTful interface to resolve GS1 IDs... use case - US Drug Supply Chain.
18:16:42 [manu]
shigeya: We're interested in using Verifiable Credentials for this.
18:17:09 [manu]
Slide 21
18:17:28 [manu]
shigeya: Here are some difficulties with resolution services - Object Naming System... DNS based pat of GS1 key to server mapping... not used other than for research purposes.
18:17:52 [manu]
shigeya: GS1 Discovery Services - centrlaized - map keys to servers, suspended until well-defined demands from industry.
18:18:14 [manu]
shigeya: but lately, there is renewed interest in mapping between identifiers and associated data, together with verification of identifiers.
18:19:06 [manu]
shigeya: GS1 is the standard on product and business entity identification,DID focuses on digital identity, we need a cyber-physical link other than humans.
18:19:19 [manu]
shigeya: DIDs could be used in the "id" fields in DID related standards.
18:19:28 [manu]
shigeya: There is a good intersection between DIDs and GS1 work.
18:20:00 [manu]
Pam: You talked about resolution and mapping - are those different things in your taxonomy?
18:20:37 [manu]
shigeya: Mapping and discovery is ... different.
18:21:23 [manu]
shigeya: RFID is ... RFID leaks information... but information record is somewhere else, stored on the server, that information may be on a single server or multiple servers... discovery service integrates all these data flows together.
18:22:13 [manu]
Topic: Laws and Borders: Self-Administered Identifiers and NextPats
18:22:17 [manu]

18:23:04 [manu]
Pindar: What about NETizen eXpatriates -- people that want to transact across borders.
18:23:13 [manu]
Slide 2
18:23:25 [manu]
Pindar: There are more people on this circle than the rest of the planet... lots of people
18:23:35 [manu]
Pindar: 50 billion machines coming down the pipeline.
18:23:47 [manu]
Pindar: The Right to Work Online -- cannot be done w/o this technologies...
18:24:07 [manu]
Pindar: I work w/ displaced people - there are more people displaced today than after WW2... 70M
18:24:08 [manu]
Slide 3
18:24:40 [manu]
Pindar: These people are away from their home countries... global climate change makes it worse... legal certainty - do they have it... these people are going to grow to 700M in the future
18:25:13 [manu]
Pindar: There is a potential billion person market here covering ... what about the lawful approach (there are non-lawful approaches to solve these problems)
18:25:44 [wseltzer]
"We're all migrants, we just don't know it yet"
18:25:46 [manu]
Pindar: Examples of this, after WWI, if your country no longer existed, passports doesn't work. How can we create a "Right to Work Online"? It's not a Sovereign view, it's not about borders, it's about topology.
18:25:58 [manu]
Pindar: How many people are in My Number? 10% of Japan.
18:26:22 [manu]
Pindar: Aadhaar is over 1 billion users... great stats, interesting ruling on constitutionality.
18:26:40 [manu]
Pindar: Aadhaar has issues, but it's deployed.
18:26:53 [manu]
Pindar: 50B devices online - we need to be concerned about scale.
18:27:29 [manu]
Pindar: There are other mechanisms in China - Social Credit System, Real Name Electronic ID, Fintech, Common CLOUD.... identities issued by governments to citizens.
18:28:49 [manu]
Pindar: There is the Belt and Road Initiative - when you cross borders, law is defined by borders - when you cross 65-68 legal jurisdiction... Hong Kong is looking at digital roots.
18:29:08 [manu]
Pindar: We have 3-5 times more internet capacity into Hong Kong than all of China combined - how is this leveraged?
18:29:30 [manu]
Pindar: What is the competitive landscale, market structure, business models... what are the fundamental tensions between geography and topology?
18:30:21 [manu]
Pindar: We are mixing fire and ice - government issued - year 1648... in Hong Kong year 2047 -- self administered
18:30:35 [manu]
Pindar: No nation below mathematics... physical border in borderless world... self-administered IDs...
18:31:17 [manu]
Pindar: Here's the belt and road blockchain - only deals w/ corporate identifiers, legal in switzerland, identifier system for corporates, self administered IDs, the most important thing is Self-Administered IDs, why do you need them?
18:31:26 [manu]
Pindar: Companies don't have a right to anonymity - they have to be registered, they have to pay tax.
18:31:53 [manu]
Pindar: We need a golden source of data, we need to know where law applies, that's one of the things that Hong Kong is famous for...
18:32:51 [manu]
Pindar: As a technical community - consistency - Hong Kong - golden copies, grounded by government institutions, use it, assign copies of data, have less legal responsibility and liability.
18:33:03 [manu]
Pindar: to scale cloud services, need identifiers system to allow different cloud systems to scale.
18:33:25 [manu]
Pindar: This is why we call them Self-Administered Identifiers - corporates/individuals... Sovrerign states - Fire... dynamic violence.
18:33:51 [manu]
Pindar: in our Internet view - borderless... ice... cryptographically strong static violence...
18:34:19 [manu]
Pindar: We need to understand consent - freeze, not move - different property that does not require rule of law -
18:35:02 [manu]
Pindar: legal certainty - many of us that do contracts don't see the light of day - computing engine of court system - interpret run legal code... computational code - cryptographic consistency - we can have a different type of discussion.
18:35:21 [wseltzer]
[slide 16]
18:35:24 [manu]
Pindar: Fundamental assumptions - distance != cost, centralized != trusted, time != money
18:35:47 [manu]
Pindar: What are assumptions implicit in our discussions... - digital trade and digital work online is different.
18:35:59 [wseltzer]
[slide 18]
18:36:03 [manu]
Pindar: We've had Cyber Monday / Black Friday - different by an order of magnitude.
18:36:18 [manu]
Pindar: Singles day is way bigger.
18:37:18 [manu]
Topic: Trusted ID
18:37:30 [manu]
Tom: We've been doing work in Kantara - a Trusted Identity
18:37:38 [wseltzer]
-> https://docs.google.com/document/d/1taCE6I8tcx5zLQ9PYcDfk6ThB3WlcISIMBfIhKKC_Bg/edit Tom Jones and Mary Hodder's slides
18:38:17 [manu]
Tom: What you see when you look at this, Authentication of a User has to be different ... Decentralized Identity on steroids - pieces of identity are spread throughout space.
18:38:42 [manu]
Tom: How to bring things back together again... talks to strong enough idea that we're trying to present to this group.
18:38:52 [manu]
Tom: Authentication and Authorization - separate and needs to stay separate.
18:39:06 [manu]
Tom: WebAuthn comes up more like Authorization...
18:39:25 [manu]
Tom: The idea is that in this use case, pretty high assurance that someone is over 21 if they need to buy some alcohol or some other restricted element online.
18:40:05 [manu]
Tom: We're going to talk about these 4 actors - consumer that wants restricted resource, supplier that has resource, verifier of claim of majority (sort of like Verifiable Credentials meaning), this verifier can validate binding between user and claim.
18:40:23 [manu]
Tom: I'll try to use validate when I say that and verified when I say verified claim.
18:40:30 [manu]
Tom: What about the right of a regulator agency?
18:40:53 [manu]
Tom: One of the most interesting cases is DEA position on drugs...
18:41:08 [manu]
Kaliya: When you say regulatory agency, do you mean provider of claim?
18:41:19 [manu]
s/Kaliya/@@@/
18:41:24 [manu]
JohnB: What requirements are there?
18:42:13 [manu]
MaryHodder: For state of California, board of brewery, had to do a deep identity verification for brewing... tap room, physical location, sell things through website and people can come in and pick up... brewing operations, they spot check, they don't look at our records for every single sale.
18:42:37 [manu]
MaryHodder: Often people flash a license... employees ar edoing that check, there is no recording except through website purchases... no one is even providing this.
18:43:12 [manu]
MaryHodder: They are literally clicking a button, which is not good, flashing license... but there is no real recording/requirement that feds and state of california require for alcohol purchases.
18:43:37 [manu]
Tom: If you are buying alcohol, you can have different requirements for different types of purchases.
18:43:53 [manu]
Tom: The specific rules differ by state - online use case, they will try to find rules that will work for all states.
18:44:08 [manu]
Tom: Last part - provider of late binding tokens and client-side code.
18:44:13 [craigspi_]
craigspi_ has joined #auth-id
18:44:41 [manu]
Tom: Smart card, TPM, etc. precondition is that you have a consumer that has a late binding token that has it, they have an over 21 claim, and finally they have a consumer that already established an ID with some supplier.
18:45:11 [manu]
Tom: They are already online... that's where we are ... two different use cases to look at this - supplier sends request through user asking for a claim... user has a claim... user sends it back.
18:45:51 [manu]
Tom: It's not verified - typically, supplier ... use late binding token to be attached to claim, late binding token is attached.
18:46:20 [manu]
Tom: If you are an OpenID person, this is just front-channel authentication... at this point, we have provided a service to supplier, we expect supplier to receive validated claim.
18:46:35 [manu]
Tom: This is small, 5-10 cents - standard practice - fraud detection circuit.
18:46:55 [manu]
Tom: Second scenario, something that looks like a back channel - consumer himself has to go and get validated claim.
18:47:03 [manu]
Tom: Gets validation, gets claim, supplier gets it.
18:47:25 [manu]
Tom: This is traditional advertising model... bound to session.
18:47:41 [oliver-terbu]
oliver-terbu has joined #auth-id
18:47:49 [manu]
Tom: Fail paths - fairly obvious, user doesn't get verified, or fails validation at supplier
18:48:11 [oliver-terbu]
could you please again share the link to the google slides?
18:48:27 [oliver-terbu]
thx
18:48:35 [manu]
s/could you please again share the link to the google slides?//
18:48:39 [manu]
s/thx//
18:49:02 [manu]
Tom: The real point is that the user gets to decide what attributes he sends based on what he's doing at the current moment.
18:49:40 [manu]
Tom: Examples of what could be used, client side code
18:50:16 [manu]
Tom: users shouldn't expose stuff to websites ... so we need a way for websites to identify themselves... trust federations apply to what we're talking about... alcohol... drugs, different rules, different conditions.

ChristopherA: The VC and DID community has been using the "Over 21" story over the last couple of years.
18:51:19 [manu]
ChristopherA: There are major differences in some places - for example item 6 - we're not trusting that the user makes the choice, the absolute minimum inormation should be given.
18:51:35 [manu]
ChristopherA: Data Minimization story there.
18:51:51 [manu]
ChristopherA: There is a separate selective disclosure story - there shouldn't be a backchannel where the bar can correlate information.
18:52:35 [manu]
ChristopherA: This is in our whitepaper on data minimization an dselective disclosure and how they're different... in the VC group, and DID group, we've decided to drop this story... over 21 is too complicated, doesn't always apply, it's problematic. We've gone to university alumni and university degree.
18:52:54 [manu]
Tom: I understand that this is a broader scope - take the claim, moves to higher plain,
18:53:02 [manu]
ChristopherA: We would be happy to share with you on this stuff.

... In implementing this ina RDMS, we threw out the X.500 idea that DN's are real names. We jammed UUIDs in the DN for people entries. and never revealed it.
19:19:44 [weiler]
... so when users entered a name in a form, we did not map that to a DN and do the lookup - we did searches instead.

... i do no t believe we should talk about DID resolution or universal resolving becasuse i think that's going to be up to the marketplace
20:13:05 [aaronpk]
... we already demonstrate that works now, there will be market realities to push people together
20:13:05 [wseltzer]
q+ re sequential standards
20:13:36 [aaronpk]
... definining a minimum viable proof of control will help verifiable claims a bunch, it will demonstrate the DID spec does what we promise, then we will talk with people who will do three party and more complex structures on the back of that as separate future working groups

daniel: in terms of the technical piece, i was curious when you bring up resolution it infers other things
20:14:11 [wseltzer]
ack Dan
20:14:25 [aaronpk]
... resolutions infer other things, we're working on batching that sticks things in bitcoin. other schemes don't do that
20:14:55 [aaronpk]
.. the idea that we standardize resolution, we'll run a plugin that resolves each one, you can't really standardize the resolution steps because they are inherently different just like you can't standardize tthe math in a cryptographic scheme
20:15:08 [aaronpk]
... so that's how you should in your mind associate a DID method's logic and what we can standardize

20:15:36 [daniel]
You're next
20:15:41 [aaronpk]
... you're mentioning some criteria of what i've heard before
20:15:57 [aaronpk]
... christopjher said we need to have a focused data model and syntax. we've been incubating a lot of these standards, we have a roadmap.
20:16:15 [aaronpk]
... one thing that mjight be helpful is to push for some clarity on what we need for working group formation so we dont' feel like we're reacting to what feel like arbitrary rule changes

zakim, please give manu the last word
20:16:54 [Zakim]
ok, weiler, the speaker queue is closed and cleared
20:16:55 [Zakim]
manu, you wanted to say JWTs are a data format, that's it -- how is that any different?
20:17:02 [aaronpk]
mike: that's a step in the right direction, i don't have preconceived boundaries on what the particulars are
20:17:18 [aaronpk]
... the particulares may be different for all of them but you have to write down one or two of them to have interoperable implementations
20:17:41 [aaronpk]
manu: i'm slightly frustrated with the direction that some of the JWT folks are taking
20:17:46 [aaronpk]
... JWTs are a data model full stop
20:17:55 [aaronpk]
... in that sense, it's strange to me that doing a data model is not enough for a WG
20:18:00 [aaronpk]
... it's a very strange argument
20:18:13 [aaronpk]
... the second thing is there are a number of companies that are building and deploying verifiable creds to real customers today
20:18:25 [craigspi_]
craigspi_ has joined #auth-id
20:18:35 [aaronpk]
... this is not a theoretical exercise, there are organizations involved i nthis work, and i'll note that those taking exception to the WG are not building these systems
20:19:00 [aaronpk]
... so as someone who is leading a company writing this code that having a DID spec in place even if only a data model is going to help greatly that ensuring this market as it's growing has something to build off of
20:19:11 [aaronpk]

21:44:23 [brentz]

21:55:57 [brentz]
ChristopherA: Yes the claim would be issued to the DID. There are correlation issues with using an identifier this way.
21:56:48 [brentz]
... the process of a verifier getting the information they need during presentation might be iterative, leading to trust between two parties.
21:57:29 [brentz]

21:57:40 [JoeAndrieu]

... an attacker who presents a facsimile should not succeed.
22:37:36 [brentz]
... the context of the biometric authentication is important.
22:37:57 [brentz]
... using different factors: time, common movement, etc.
22:38:28 [brentz]
... [IEEE 2410-2017 slide]
22:39:32 [brentz]
... what we discovered in the marketplace, mobile to mobile mode needed to be updated to support server-side.
22:40:15 [brentz]
... m2m is good for authentication, basically equivalent to FIDO.
22:40:41 [brentz]
... will be FIDO certified in the future.
22:41:34 [brentz]
... In other cases, for account recovery, using Shamir secret sharing with one piece on the device and another on the server, allows server-side protocols to avoid storing the biometric fully on the server.

22:42:22 [manu]
q- oh...
22:42:26 [manu]
q- it
22:42:34 [brentz]
... the idea is we want to cover global needs
22:42:57 [brentz]
... instead of going through a KYC process (which may involve biometrics)
22:43:20 [brentz]
... you can do different things [slide: initial onboarding]
22:43:40 [brentz]
... doesn't require subsequent biometric enrollment
22:43:56 [brentz]
... reduce friction but support KYC/AML
22:44:50 [brentz]
... there are places this is required. Once biometric check is done, it can be thrown away.
22:45:09 [brentz]
... there are only a limited number of cases that require central storage.
22:45:31 [brentz]
... SSI Biometrics would allow for roaming KYC.
22:45:49 [brentz]

22:47:11 [brentz]
jzcallahan: how could we do biometric authentication in a Web Authn context.
22:47:32 [brentz]
... [slide: Biometric DID Auth]
22:49:22 [brentz]
... this is a proof of conecpt for how these things could be tied together.
22:49:27 [wseltzer]
jbradley: that's easily phishable
22:49:40 [wseltzer]
... it fails at the QR code
22:49:45 [brentz]
... failed at the QR code
22:50:07 [brentz]
jzcallahan: you have a cloud agent acting on your behalf
22:50:26 [brentz]
... Sovrin and uport could be used on the back end.
22:50:45 [brentz]
... allows KYC vendors to monetize their process.

Jill: can your system account for simple dynamic things?
22:51:46 [brentz]
jzcallahan: We don't want to handle the whole VC thing, we want to stay in our lane and provide biometric credentials.
22:52:13 [brentz]
... KYC is the gate, the ongoing AML is where the costs lie.
22:52:26 [burn]
s/whole VC thing/whole KYC thing/
22:52:27 [brentz]
... we are paying close attention to the VC work.
22:53:04 [brentz]
Jill: client onboarding happens first, but you need to update who your customer is, that's what KYC means.
22:53:40 [brentz]
jzcallahan: we don't want to do our own transaciton monitoring, we want to provide the biometric claim that exists as part of the rest of the ecosystem.

... PSD2 regulation discussion
22:55:25 [brentz]
... [slide 1] two objectives.
22:55:38 [brentz]
... banks are very protective of their customers and the data
22:56:00 [brentz]
... this is not currently optimally done.
22:56:43 [brentz]
... lots of data breaches and account takeover. goal is to reach same level of assurity with e-commerce as with chip cards.
22:57:15 [brentz]
... [slide 2] European banking organization created SCA
22:57:34 [brentz]
... essentially 2FA
22:57:52 [wseltzer]
Marie: PSD2 takes effect Sept 2019 for any banks or retailers in Europe or doing business in Europe
22:57:53 [brentz]
... but also requires dynamically linked data
22:58:48 [brentz]
... [slide 3] shop authenticates user out of band
22:59:07 [brentz]
... issuer decides everything in this model
22:59:18 [wseltzer]
[slide 4]
22:59:25 [brentz]
... not in line with what retailers need
22:59:37 [brentz]
... retailers want control
23:00:08 [brentz]
... this will affect the bottom line
23:00:09 [wseltzer]
[slide 5]
23:00:18 [brentz]
... they are looking for alternatives
23:00:26 [wseltzer]
[slide 6]
23:00:49 [brentz]
... merchant will authenticate the user.

23:01:46 [brentz]
... credit cards are determining the framework.
23:02:15 [brentz]
... FIDO and Web Authn seem like a good solution.

23:10:43 [brentz]
Marie: it is connected to the directory server.
23:11:21 [brentz]
tomj: should a relying party be required to accept authorizarions from unrelated parties?
23:11:29 [brentz]
... this could create a real problem for this group.
23:11:50 [weiler]
tonj: banks need to be fiduciaries for the customer, not the merchant
23:12:11 [brentz]
Greg: I was in Paris with Visa, just talking about this. banks need to be fiduciaries for their customers.
23:12:25 [brentz]
... in Europe this is different than in the US.
23:12:52 [brentz]
... with PSD2, privacy rights are treated like human rights, in US they are contract rights.
23:14:14 [brentz]
... the contract orientation and the elevation of terms of use means it is very difficult for self sovereign identity to triumph.
23:14:52 [brentz]
