Self-Sovereign Identity:
Your data under your control

SSI has been developed to support interoperable digital environments for efficiency, trust, and protection of user rights. With the preservation of privacy as the greatest good.

It starts with three main players

A Self-Sovereign Identity ecosystem is built around three primary participants. Three players who form a triangle of trust.

1. Holder

The owner of the identity and the holder of the personal data or credentials. This, a student or employee, shares data with others.


Trusted party that provides certificates to the holder in a secure manner and digitally signed. An issuer is a educational college or a training institute.

3. Verifier

The party that wants to validate the authenticity of the holder's shared credentials. These can be employers, authorities, or educational institutions.

What is a Self-Sovereign Identity?

SSI gives identity holders control over their own data. Current systems, such as an email service provider, can act as identity providers. Data is then stored in the provider's databases and shared with other parties. A Self-Sovereign Identity, on the other hand, is kept by the holder on their own device. This can be a mobile phone, computer, or smart card.

The identity holder creates their own unique identifier (referred to as a decentralized identifier - or DID). This DID is then connected to trusted providers, such as (local) governments, banks, and social services, who are able to issue cryptographic credentials, that the identity holder can then store, securely in an encrypted identity wallet.

The full control over the connection with their own identity, with whom and when it is shared, lies with the identity holder. To break this connection, the holder simply removes this authorization to connect to the identity wallet.

A student name Sienna.

Let us take a student, we'll call her Sienna, as an example. Sienna completes a course at a college. This college issues a certificate upon completion of the course. Sienna, as the holder, can now share this certificate with a potential employer. They can verify its authenticity and trust that the issuer has issued it via cryptographic verification.

The added value

There is so much to gain from such exchanges in the world of Self-Sovereign Identity. Not only privacy and control for the holder, but also validation and verification for the issuers and the verifying party.

Sienna has control and autonomy over who gets access to her data and when. She has full ownership over the portability of credentials.
By creating a more efficient issuance system, the issuer complies with privacy guidelines in managing learner information.
Verification is simple: verify the authenticity of credentials directly without additional tools, time, or third-party assistance.
