# Secure ID Verification

The **Secure ID Verification SDK** allows you to verify your users' legal identities. This is essential to comply with regulatory requirements, such as know-your-customer (KYC). Secure ID verification is required to unlock certain Sudo Platform features, such as [Virtual Cards](/guides/virtual-cards.md). Secure ID verification also offers you peace-of-mind that your application isn't being misused.

Your users will be asked to verify their identity by providing proofs that can be verified against trusted data sources.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sudoplatform.com/guides/identity-verification.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
