The document discusses using blockchain identity and self-sovereign identity protocols to securely verify credentials in real-world scenarios. It proposes demonstrating this on a Raspberry Pi by creating a single sign-on application that can validate a user's credentials through the Pi and trigger real-world actions. A potential demo case is described for carsharing, accessing locations, or using age-restricted vending machines through verified digital identity.

2. It all begins with a
pretty common
question…
How do we securely verify
credentials in real life?

3. Furthermore, what sort
of real life scenario can
we realise its
demonstration?
●The metro?
●Buying cigarettes?
●Carsharing?

4. The next small thing in
the world of digital
identity!
● Particularly essential in some systems –
especially IoT use cases
● Status quo has them solved via centralised
platforms
● i.e. Government-issued ID
● Individual accounts on a product by
product basis

5. Inherent Problems
● Revealing than is necessary. The classic
passport at the bar scenario.
● Too many applications/accounts
● Tempting honey pots of user data
● Culminates in a poor experience for the
user

6. Self-sovereign ID
protocols
These may solve many of these persisting issues

7. An open-source ID
protocol
● Validated Identity on the
blockchain
● Mobile Wallet
● Intuitive UX
● Support for issuing credentials
to wallets

8. So . . . What did we do??
We wanted to add upon their credential idea by creating a real world use
case
Jolocom’s SSO application now functions on the Raspberry Pi
microprocessor
Validate a user’s credentials with Raspberry Pi, reflect that through
real-world actions

9. Demo

10. Potential use cases
● Vehicular rental / Carsharing
● Location access
● Age-restricted vending
machines
● Probably way more...
