Blockchain-enhanced Identities for Secure Interaction

Securing identities in online communities like Facebook and Google requires thinking beyond mobility and cloud as federation methods can be gamed. While use of adaptive authentication and biometrics on mobile devices has become the norm, its security can be bolstered lot more with a distributed ledger like blockchain. This paper presents an augmented security model based on the blockchain distributed ledger, depicting how blockchain can help us build decentralized identity ecosystem.
