# User Data User Data encapsulates a spectrum of sensitive and confidential attributes, ranging from governmental identification forms like driver's licenses and passports to financial credentials like bank account details. In the zkPass model, this data is owned by the Data Holder (User) but provisioned by an entity known as the Data Issuer. Notably, the zkPass framework accommodates a high degree of data schematization flexibility. It is engineered to be agnostic to any particular data schema, seamlessly interfacing with JSON objects or any other structured format specified by the Data Issuer. The eventual consumer of the data user is the zkPass Service. For a complete definition of the user data, please follow this [link](/zkpass/getting-started/key-concepts/user-data.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
