# Features

## What can you do with All.id?

With the All.id network it is possible to quickly configure your applications and start using the following functionalities:

* **Facial biometrics (1:N analysis):** For onboarding or first authentication. By comparing a selfie and CPF with existing data within the All.id network, the recognition process is simple and efficient.
* **Facial authentication (1:1 analysis):** Ideal for situations where the identity has already been validated previously. Facial authentication allows quick and low-cost access by comparing a selfie with a reference image previously validated by the facial biometrics process.
* **Facial recognition (1:N comparison):** It has multiple applications within biometrics-based solutions. Allows the comparison of a selfie without having to inform a unique identifier and compare it with all (hashes of) images of the peer stored in the peer itself or with a restricted list, of suspects for example, maintained within the network. There are several uses for facial recognition on the platform, the main ones are: profile comparison (on-peer) and blocklist.

## 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.caf.io/caf-docs/user-guide/resolution-6/facial-biometrics/features.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.
