Blockchain Digital Identification

By taking advantage of the blockchain's distributed ledger, which allows hosting and unlimited transactions of valued assets, legal and digital identities could be verified, and thus be less prone to fraud. This service automatically verifies a person’s past documentation records by linking them to their birth certificate, social security number, passport, and other official papers through Smart Contracts. Authentication takes place using one or more approachess such as: data that the person knows (a password, for instance), something that the person owns (such as a mobile phone or a blockchain wallet), or something that the person is (biometric data).

Individuals that enter the blockchain database, therefore, could be provided with rights such as opening bank accounts, signing contracts, or applying to university. In addition, this solution offers data and identity security and accessibility to immigrants and refugees who might have lost documents and proof of existence. However, from governments to organizations, a set of standards should be established to consolidate the implementation of this type of digital identity.
