With the help of the wallet, the user can limit the disclosure of his data to those attributes that are necessary for the provision of the service, e.g., a user's legal age or a successfully completed university degree.

This selective disclosure enables an individual to share parts of a larger data set.

In the event of a data leak at the company, no personal user data, such as date of birth, can be leaked because, in this model, the company never had that data.

Thanks to ZKPs, the use of personal identity data can be significantly restricted.

As a result, the model goes far beyond the principle of data minimization, which has often been difficult to adhere to in practice - or is deliberately not adhered to by individual companies so they can keep the generated data sets as large and extensive as possible for marketing purposes.

Thanks to selective disclosure functions, the user regains control over their digital life, personal data and the dissemination of this data.
