uPort: Self-Sovereign Identity & Key Management
uPort is a self-sovereign identity and key management system that allows users to control their own identities and data. It uses blockchain and cryptography to give users ownership over their digital identity.
What is UPort?
uPort is a self-sovereign digital identity system built on the Ethereum blockchain. It allows users to completely control their own identities and personal data without relying on central authorities.
Some key features of uPort include:
- Decentralized identifiers (DIDs) - Users generate their own blockchain-based decentralized identifiers that serve as their digital identities.
- Selective disclosure - Users decide what personal data to share and with whom through cryptographic verification.
- Reusable know-your-customer (KYC) data - Users can complete a KYC process once and reuse that credential to onboard with other uPort-compatible services.
- Cryptographic signing - uPort uses public-key cryptography to sign claims and prove identity or verify attributes.
- Mobile-centric - The uPort app serves as a user's identity wallet and signing device for cryptographic functions.
By giving users control over their digital identities and data, uPort aims to solve problems related to centralization, privacy violations, and exclusion that plague traditional identity systems. It has the potential to facilitate identity ownership, interoperability, and financial inclusion.
