Description: E-Identity refers to a digital representation of an individual’s identity on the blockchain, allowing users to manage their identity securely and privately. This form of digital identity is based on blockchain technology, which provides an immutable and decentralized record, ensuring the authenticity and integrity of data. E-Identity enables individuals to control their personal information, choosing what data to share and with whom, thereby reducing the risk of identity theft and fraud. Additionally, it facilitates online identity verification, eliminating the need for intermediaries and simplifying processes such as authentication in digital services. E-Identity is particularly relevant in an increasingly digitized world, where privacy protection and data security are paramount concerns. By integrating E-Identity with interoperability systems, solutions can be created that allow users to access multiple services using a single digital identity, enhancing user experience and fostering trust in digital transactions.
