PARTICIPATION IN THE DIGITAL WORLD
Professional networks
Web services
Commerce
Marketplaces
Identity is central to nearly every interaction ...
Social communities
ACCESS TO TRADITIONAL SERVICES

Today’s identity silos are inaccessible, ineffective & insecure...
Government records
Hospital(s)
Tax authority
Car registration authority

● Traditional forms of identity still unavailable to many
● Requires repeated use of physical identity proofs
● Digital literacy may preclude access to digital identities
INACCESSIBLE
1.1B individuals cannot prove
their identity today
● Vulnerable to hacking and theft and leave users’ data unprotected
● Consolidation & correlation of data decreases privacy
● Control sits with central orgs who often behave irresponsibly
INSECURE

● Limited information sharing prevents collaboration, interoperability & efficiency
● Repetitive account creation; inconvenience of remembering passwords
● Cannot be extended to reputation, zero-knowledge verifications, etc.

Self-Sovereign Identities as next step in the evolution of identity...
Decentralized IDs2017
Users’ credentials stored by federated identity services that
provide authentication
Widespread adoption of national IDs and passports after
WWI/WWII
National IDs 1900s
Access to digital services with 'online accounts' for
each service
‘Digital’ identity1990s
Federated Identities2010s
Self-sovereign identity via blockchain allows more private, more secure and more useful
identity, centered around users
Verifiably credible identities, individually secured access yet globally persistent experience
Nationality as the basis for credible identification
Individual account log-ins and identities to access various
digital services
Single Sign-On (SSO) and more persistent experiences by
entrusting accounts to a few large players

Ethereum & Identity
![Page 7: 【Blockchain EXE NY】Self Sovereign Identity - Smart homes & Smart contracts](https://reader031.fdocuments.net/reader031/viewer/2022020411/5a64785a7f8b9a27568b45b3/html5/thumbnails/7.jpg)
Intersection of two related challenges ...
Blockchain for Identity
Self-sovereign identity can be realized with blockchain and smart contracts
Identity for Blockchain
Identities with private keys are required to interact with blockchains
Challenges today:● Identity Ownership● Data Ownership● Reputation Fragmentation● Password Management
Challenges today:● Key Management ● Persistent Identity ● Authenticating the User (link to ‘real-world')

Introducing uPort
A complete self-sovereign identity solution: secure mobile app and dev platform, for both decentralized (web 3.0) and server-based (web 2.0) apps
Identity rooted in Ethereum blockchain
Passwordless, Single Sign-On
Simplified user centric key management
Browser to mobile app communication
User credentials & reputation foundation
Identity verification / KYC
Private chain support
uPort features
Binding digital signatures

Ethereum & IoT
![Page 11: 【Blockchain EXE NY】Self Sovereign Identity - Smart homes & Smart contracts](https://reader031.fdocuments.net/reader031/viewer/2022020411/5a64785a7f8b9a27568b45b3/html5/thumbnails/11.jpg)
Ethereum & IoT - a powerful combination
● Independent registration
● Permissions / access rights
● Smart Contract based actions
● Programmable payment integration

Ethereum, IoT & uPort
![Page 13: 【Blockchain EXE NY】Self Sovereign Identity - Smart homes & Smart contracts](https://reader031.fdocuments.net/reader031/viewer/2022020411/5a64785a7f8b9a27568b45b3/html5/thumbnails/13.jpg)
Ethereum, IoT & uPort - ideal combination… ?
● Things need identity too
● Ownership associate to (human) identity
● User centric; delegation to people
● Cross industry / ecosystem
● Privacy / Security / User data (e.g. history, preferences, ...)

Example - 'Airbnb' scenario of the future
● Find a place
● Check the mutual reputations
● Confirm the agreement
● Escrow money
● Automated access (e.g. smart lock) & payment
