Abstract

Nowadays, there is a problem on the Internet with the overabundance of information controlled by a single entity (e.g. person, organization), which we don’t know at all. Self-sovereign identity is a framework of trust where entities such as people, organizations, and abstract entities, have their own fully autonomous identities. With the help of decentralized identifiers and verifiable credentials, this type of decentralized digital identity enables entities to securely communicate, control their data, and choose what and with whom to share. Data exchange occurs using a blockchain and a distributed ledger technology, which allows for protected and safe transactions. With the help of this new technology and the Cardano blockchain, we have developed an open-source solution to help students in their educational process.
This solution allows us to present the decentralized digital identities’ functionalities in education. Using SWOT analysis, we compared the system to existing solutions, proving that self-sovereign digital identity makes our solution more secure, robust, cheaper, and practical.
