Key Phases in the Evolution of Digital Identity
In the process of developing a digital identity, there are four stages:
- Password and username: It’s the initial stage of digital identity, usernames, and passwords were used for verification.
- Centralized Identity Management: During the second phase, methods for managing personal information through centralized identity management began to appear.
- Federated Identity Management: The third phase featured the development of federation identity management systems, in which several organizations could trust each other to handle identity information.
- Self-Sovereign identification: The present stage of digital identification is in its fourth phase, which involves the development of decentralized identity management systems in which individuals control and own their data.
Blockchain, Self-sovereign Identity and Digital Credentials
A decentralized, secure ledger that is open to many parties is blockchain. It keeps track of all computer network transactions, and once data has been stored, it cannot be altered or removed. Consensus methods and cryptographic techniques—which call for agreement among network users—are used to accomplish this security. The network keeps the ledger up to date and uses consensus to confirm transactions, preserving the accuracy of the data.
In this article, we will discuss What is SSI, Digital credentials, and how they used blockchain technology extensively.
