What is Digital Identity?

A digital identity is data that is used to represent an individual, organization, or device. For individuals, digital identities can be digital versions of government documents that verify one's date of birth (DOB), nationality, sex, and other important information. It also refers to an individual's social media profiles, email, and internet usage history. The concerns with digital identity — particularly for individuals — typically revolve around security and personal privacy. Often in blockchain, a digital identity is directly linked to a Decentralized Identity (DID), which once established, allows for a blockchain-based ID that can be verified through key-pair cryptography.
