From YouTube: TrustBloc: Fostering Secure Identity Verification in a Hybrid Solution - Dmitry Barinov

Description

TrustBloc: Fostering Secure Identity Verification in a Hybrid Solution - Dmitry Barinov, SecureKey Technologies Inc.

Verifiable credentials are an essential part of our digital identities. Driver’s licenses, passports and birth certificates are some of the documents used by companies and governments to verify individual identities prior to conducting transactions. Dmitry will speak to SecureKey’s TrustBloc, which will provide interoperability between decentralized solutions, making it easy for organizations to issue and accept verifiable credentials from users. This open-source initiative allows digital wallets to store and deliver information and authorize credentials like credit scores as part of a hybrid model solution. Dmitry will also touch on the Orbs decentralized identifier method, which enables users or entities to create self-certifying decentralized identifiers that are propagated across a decentralized network without reliance on a common blockchain for coordination.

A

So hello, everyone, um my name, is dimitri varanov and I am from a security organization and what I will talk about. I will talk about our project called.

B

A

And how it is related to the hyperledger foundation and on our plans on developing basically interoperable identity and data exchange solutions, so a little bit about security. uh This is just to show that we have we're not new in the industry. I would have been doing identity solutions for a while.

A

uh We are running a number of the running, an identity network based on the decentralized.

A

Solution, decentralized, ledger and hyperledger fabrics in 2019 in canada. We have millions of users on the network right now, so it's quite successful, and uh this year we have deployed a new solution um called trustblock, and I want to talk a little bit about that.

A

So, basically it is very clear to us and it is very clear to the identity community and the day they change community.

A

That interoperability is the key and the main drivers uh for interpretability standards come from w3c from the deep foundation and from ipf, and that the new solutions in the data exchange and identity world would require vendor independence and would require ledger independence as well, so that customers of these solutions are not tied to any particular vendor for any particular piece of technology, uh and uh they can migrate from battle to vendor and uh obviously can make their own operational decisions and trust decisions as well.

A

B

A

um It was very clear working with our partners that um we must enable uh standards in the systems and uh their main standards are verifiable credentials and decentralized identifiers, and obviously it was also very clear for us that commercial.

B

A

A

A number of others community related and community-based standards being implemented in that such as we definitely need to uh take a close look at the implementation of the http issue and verify our apis, because this is actually a very normal way of how uh enterprise organizations communicate uh on the internet.

A

We need to be very careful about using standard.

B

A

Definitions, presentation, request language is very, very important in many floats of the solution and then, of course, the proper security uh associated with cloud index management services, encrypt data roles, management services are very important, and another very important, of course, is ability to rely on the w3c standard for the universal wallet and for standard integration methods such as oedc of now.

A

So what we have done, we have introduced the transport project and the trustworth project basically has several. Very ambitious goals um has a goal of providing digital governance and interoperability for trusted identities, but also to provide interoperable framework that allows issuance and verification of credentials, user management of identity and moderation of the flows. It was very important for us, so, basically we started building the project project is an open source um project. It is uh described, it is only github, it has registered the two registers.

A

Actually I did methods, one is called trustwork, another one is called orb and uh what was very impor? What became very evident to us in the middle of the project that we wanted to have an orb method uh to extend the site revertal, which we rely on uh to ensure that we can offer ledger agnostic deployments.

A

Obviously, we have to support the adapters uh to ease the integrations, and we also wanted to provide options for user chosen database that can also offer different services and where the users can securely store their data.

A

And, of course, these options should include the option of storing the data on device or in the cloud or at the trusted property.

A

uh Another important uh transport characteristic is that we are ensuring um a classic verifiable credential uh data interaction method and where the data is issued to the device recovery credentialization to the device. I shouldn't call it data, of course, and we also support a method which is very important for many use cases where we support just-in-time exchanges.

A

So um obviously we are, we have been involved with hyperledger foundation for a number of years. Our first engagement was um where we started uh using the fabric code and contributing to the fabric code, but for the interoperability uh we contributed significantly to the aries framework goal and we based um our translocative credential services and bullets uh on aries framework goal all right. Another.

B

A

Point is um that we're using basically a ledger as a root of trust for the dids, uh but we also wanted to ensure in truss block that organizations have a choice, and this is actually again why we introduce this orb method, uh an orb functionality uh where um implementations can be uh ledger, independent.

A

Another important point is the trustwork is using bitcoin implementation to allow data exchanges uh with governance and mediation and did come, of course, is based on aries rfp and if work and right now we're working on basically allowing communication between w3c compliant systems and indeed based systems, um ensuring that we can add privacy, mediation working on integration between areas, framework go in hyperledger areas, cloud asian, python or akapai, as it's known right, we're obviously very much interested in extending the support uh to the privacy based on the bbs plus and so on so forth.

A

um So the demo that I wanted to show before we get into the any questions uh period and the demo is actually very important. I wanted to talk a little bit about them, so all our demo, practical demos they are based uh on the artifacts that are developed through the department of homeland security svap project, where we are working in partnership with a number of companies, including denuclear digital bazaar, metal, maintenance, severity, transmute industries and where we demonstrate that uh interpretability based on w3c test suite.

A

uh So the example that we're going to show our show we're going to show this interpretability based on that includes an example where we selected disclosure of some attributes on the network uh that leverages dbs plus, and we also obviously development, but we're also using the technology which is uh based on the development draft standards. So we do include decentralized identifiers, universal resolver, credential, handler apis uh and verifiable.

A

Verifiable presentation, request, specifications and dc-htcp apis. So maybe now we can, if we can show the demo now and see, um are there any questions or follow-ups to this.

A

Video, hopefully you can see it well.

B

Hi, my name is mike browntown security. Our goal of security is to ensure that people can efficiently prove their identity to access the services they need. Our digital identity network allows people to verify their identity by leveraging existing credentials to access the services they want. With this, we are putting people in control of their data.

B

Verifiable credentials play a critical role in our digital identities as documents such as passports driver's licenses, birth certificates are regularly used to verify identities. As part of this, we are thrilled to be working with the united states department of homeland security and their svip program.

B

This demonstration will show a multi-credential presentation with selective disclosure featuring a permanent resident card and a vaccination certificate credential using our trustworthiness so we're all set it's time to fly, decides to go on a little vacation he's gone through and completed his reservation, and this particular small airline is taking advantage of the fact that there are digital wallets out there and issuing a digital booking reference so that they don't have to manage their own airline.

B

He's linking his wallet and collecting is.

B

Bookings, that's it he's all set to go.

B

Time passes and it's time to check in there are two options for taylor charter flights. You can do a digital case. You'll need check-in, compatible wallet, your booking credential, a real gsa, real id vaccination group. There is a manual option, but because it has to check some back-end databases, they're going to charge 25.

B

B

This is a final information check. Do you have your working preference? Do you have a tsa real id for which the us qualifies and do you have a vaccination from a qualified issue? They don't need their whole vaccination group. They only need to know that you have that advancement.

B

There are two options you can perceive in the browser or if you have a mobile wallet, the scanning qr code, to use your mobile app. We know how to browse your wallet so we'll proceed with this.

B

Here's the wallet review screen booking reference will be passed over permanent president carter passed over and incredibly passed over, but only these fields, the issuing country as the limited disclosure capability of that pbs plus credential.

B

All of these have been now verified and now go on to his get his voice.

B

What's next for trust, blog we'll be working on a cleaner ui, we'll be working on in-person and offline use cases and we'll be working on a native wallet experience to learn more go check out our github pages. Thank you very much.

A

Oh okay, so uh that was the demo and in the demo we were showing basically their uh web wallet, uh implementation uh on the transloc system and once again the system is completely interoperable and uh based on the wcc credentials and has been tested uh against other vendor implementations of the technology. So it's not the same. I use case kit. Obviously there is a trustbox channel.

A

You can see more videos if you're interested of this interoperability testing and there are more videos on the capabilities on the system as well, and uh if you uh have any questions or would like to follow up, I would be more than happy to be in the please contact me directly uh dividend security.com uh with that the session is over. If there are any questions, I would be more than happy to answer them. If not, uh please feel free to follow up again.

B

I don't see any questions in the q, a I'd like to thank everybody for for coming over.

A

Thank you very much, bye-bye.
