# Automatically reject files containing copyright

This demo showcases how to reject any files containing copyright, this is achieved by checking our files meta description and only allowing files containing no copyright metadata to be passed through.

Now we know what we will be creating, let's break down what's happening.

Using [🤖/file/filter](/docs/robots/file-filter.md) we can setup various meta data conditions ourRobot can follow. By using the [Job Variable](/docs/robots/file-filter.md#job-variables) `file.meta.*` we specify that any file containing no value in the copyright meta data field can be passed, this will ensure no file you use in your templates contain copyright.

For this demo, we had to add copyright metadata to a file. If you want to do that, please see the following [demo](/demos/media-cataloging/write-metadata-to-an-image.md).

Step 1

### Handle uploads

We can handle uploads of your users directly. [Learn more ›](/services/handling-uploads.md)

```
":original": {
  "robot": "/upload/handle"
}
```

🤖 [/upload/handle](/docs/robots/upload-handle.md)

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2

### Filter files

We let you reject, or direct files against different encoding Steps. [Learn more ›](/services/file-filtering.md)

This bot directs files to different encoding Steps based on your conditions

Step 3

### Export files to Amazon S3

We export to the storage platform of your choice. [Learn more ›](/services/file-exporting.md)

Loading Uppy demo…

This live demo is powered by [Uppy⁠](https://uppy.io/docs/guides/uppy-transloadit/), our open source file uploader that you can also use without Transloadit, and [tus⁠](https://tus.io), our open protocol for resumable file uploads that is making uploading more reliable across the world.

## So many ways to integrate

Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.

#### Bulk imports

Add one of our [import Robots](/services/file-importing.md) to acquire and transcode massive media libraries.

#### Handling uploads

We are *the* experts at reliably [handling uploads](/services/handling-uploads.md). We wrote the [protocol⁠](https://tus.io/) for it.

#### Front-end integration

We integrate with web browsers via our next-gen file uploader [Uppy⁠](https://uppy.io/docs/guides/uppy-transloadit/) and SDKs for Android and iOS.

#### Back-end integration

Send us batch jobs in any server language using one of our [SDKs](/docs/sdks.md) or directly interfacing with our [REST API](/docs/api.md).

#### Pingbacks

Configure a [notify\_url](/services/content-delivery.md) to let your server receive transcoding results JSON in the `transloadit` POST field.

#### On-demand

Use our [Smart CDN](/services/file-importing.md) to adapt files on-demand and stream them directly to your users.
