# Overview

## What is Digital Identification?

Digital Identification is a means of identifying 'who you are' through some kind of digital medium. The digital medium could be any device such as a mobile phone or a computer or anything that has a digital means of identifying 'who you are' in both offline and online mode with your consent irrespective of your religion, caste, creed, gender, country and ethnicity. The Internet is only an enabler but is not the mandatory requirement for digital identification. While identifying 'who you are', the user bearing the identity must have absolute control of revealing a controlled set of information that they wish to reveal and not everything in order to become eligible for getting a service rendered.

## What is a foundational ID system?

Governments are exploring the development of multipurpose foundational ID systems, in which individuals receive a unique identifier from the government that they can use for identity assertion and verification. It can then be used to access a wide variety of government and private services.

Functional IDs are the IDs that are used in specific use cases. By design, they are created having the final usecase in mind such as healthcare, finance, banking, insurance, social and civil registry etc. The Functional ID systems can leverage the Foundational ID system.

## Building a national ID system using MOSIP

National ID systems can leverage MOSIP as the base platform and configure, customize, and extend it to build systems just the way needed. The image below depicts how MOSIP provides the base layer to build a national ID platform.

## 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.mosip.io/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/overview.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.
