Personal Identity on Blockchain

Abstract

The problem of fraud identity documents is a fatal problem. This severity is due to the method currently being employed to create and authenticate legitimate documents. Creation of identity document requires an individual to convince appropriate government authority by producing all supporting proofs of identity declaration. This process is vulnerable as it can result in the accumulation of power to the individual issuing the identity document. Also, the authentication process involves sharing the copy of already issued identity proof. Many a time, identity proofs are shared with individuals who cannot be trusted for their integrity. This can result in misuse of the identity documents for socially evil activities. Blockchain provides a decentralized trust-less network which nobody owns, but everyone can use. The proposed system provides solution to the identity management problem by putting personal identifiers on blockchain. Using blockchain technology, a system has been proposed to create, manage and confirm an individual's identity and credentials in a much secure way. Sharing of relevant information would be possible only with the identity owner's will. Hence, creation of false identity documents will be prevented.
