Self-sovereign identity Lab TNO

The lab develops open-source tooling for SSI-wallet interoperability TNO EASSI, as well as open-source terminology tooling

The purpose of the lab is to provide tooling and hands-on knowledge for governmental and business projects that aim to implement SSI technology to further rationalise and automate and rationalise decision processes.

What is SSI?

SSI (Self-sovereign identity) is a set of cybersecurity technologies that support the exchange and processing of personal information (passport, diploma, driver’s license, bank, insurance, chamber-of-commerce, ...) in a privacy-by-design manner.

It enables counterparties to obtain sufficient assurances to enter a transaction, whether it is a car rental, a webshop purchase, a mortgage, a new employment, or other.

For example, by sharing a diploma via SSI, the prospect employer can automatically verify the authenticity of the diploma and the graduate, without needing to inform and check with their university.

Protecting Sensitive Parts of Credentials with Cryptographically Enforceable Policies

The Self-Sovereign Identity paradigm gives users control over their own data. This control does not mean that they should always be able to see that data.

The Myth Of Control in Self-Sovereign Identity

The term `Self-Sovereign Identity` (SSI) starts from the principle "Users should control their identity". Read how we distinguish reality from wishful thinking.
