The TNO SSI Lab is a cross-project initiative that develops and validates technologies and standards for self-sovereign identity (SSI). Businesses can use this very easily for negotiation and execution of (business) transactions with other organizations and individuals alike.

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.
