# Mobile

Faceplugin Face Liveness Detection Mobile SDK. On-premise anti-spoofing for Android and iOS. Passive liveness against photos, screens, 3D masks, and deepfakes.

Standalone presentation-attack detection on Android and iOS. The demo scores whether the face is **real**. It does not enroll people or run 1:N search.

Live camera (VideoWorker plus `faceDetection`). Score **0.5 or higher** is treated as Real / pass.

If you already use Face Recognition Identify on mobile, that flow already includes **passive 2D liveness**. Choose this product when you need anti-spoofing **without** enrollment.

For JPEG-over-HTTP on Windows, Linux, and Docker, use [Server SDK](/products/face-recognition-sdk/liveness-detection-sdk/server-sdk.md).

### FAQ

**Is this active liveness?** No. This product is **passive** anti-spoofing (no smile / turn-head challenge).

**Flutter / React Native?** There is no public Face Liveness Flutter or React Native SDK. Use native Android/iOS, or 2D liveness on Face Recognition Identify.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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 following URL with the `ask` and `goal` query parameters:

```
GET https://doc.faceplugin.com/products/face-recognition-sdk/liveness-detection-sdk/mobile-sdk.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

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.
