Yivi

Yivi is an app for digital identity that allows users in the Netherlands to store digitally signed personal properties (or attributes) from different trust issuers. Their data is stored in the Yivi app (or "wallet") from where users can then choose what attributes to disclose to others, for example when authenticating online.

Yivi gives users the power to chose which attributes to reveal. With the Yivi mobile app, users can verify themselves accordingly, depending on the service they are using. When buying a movie on a streaming service, for example, an end-user can reveal they are older than 16, without having to prove who they are.

Yivi is an digital identity wallet preparing to align with the European Digital Identity (EUDI) Wallet standards to support attribute-based credentials.

Yivi roles​

In the Yivi framework, the following roles exist:

  1. Users: The end-users who have Yivi on their phone, containing cards with personal data. Users identify themselves with Yivi by sharing relevant data from their digital cards.
  2. Verifiers: The organisations that want to know something about users and request that information through Yivi. Users disclose their data to verifiers.
  3. Issuers: The organisations that issue personal or other data types to users, in the form of cards in their Yivi app. Users can then identify themselves to verifiers with the data on those cards.

The verifier can verify that certain attributes were given to the user in the past by validating the issuer's digital signature. They can then confirm that the attributes have not been modified since they were previously authenticated.

Key features​

  • Free and open source.
  • A safe and secure method of authentication for the end-users.
  • End-users choose when they share data from the data cards, and who they share it with.
  • No fixed set of attributes provided. The end-user fills their Yivi wallet with verified attributes from various sources to then be enclosed to a verifier when the user gives consent.
  • End-users can digitally sign documents by disclosing only selected relevant attributes about themselves.

Yivi app​

The Yivi app is a free mobile application that allows users to control the data they want to disclose when they log in, share data and prove who they are online.

The app is created by the Privacy by Design Foundation. You can download the app for free from the Download Yivi page.
