● 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
Self-Sovereign / Decentralized ID systems solve existing challenges
User controlled Distributed SecurityUnified, Private, Portable
Building reputations Device control
Ethereum & Identity
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')

Ethereum, IoT & uPort
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, ...)
