Filtering Images

Available since 3.28.0

1. Filtering Images

Filtering images is easy with the new media filter

1.1. Prerequisites

  • You have contacted CleanSpeak to have the MediaFilter enabled for your license

1.2. Considerations

  • You will be billed per operation

    • An operation on an image is simply the number of enabled filters

    • Animated GIFs are billed using operations := number of filters enabled × number of frames in the GIF

1.3. How to configure CleanSpeak to use this feature

1.3.1. Setup the image filter

  1. Navigate to your application configuration

  2. Enable store content

  3. Click the media tab

  4. Enable the image filter (if the image filter is missing then your license does not have the media filter feature enabled and you will need to contact sales)

  5. Enable at least one filter type [Nudity, Scam, Offensive, Weapon/Alcohol/Drugs]

  6. Select at least one filter action for the enabled filter (if everything is allow then it will treat the filter as disabled)

  7. Click save

1.3.2. Moderate some content

You can now submit content to this application via the moderate endpoint.

Image moderation works exactly the same as text moderation so you will get a filter response when the filter process is complete.

1.4. Example usage of the filter

URI

POST /content/item/moderate

For persistent content you will need to provide a unique identifier (UUID) on the API request. When using this API with persistent content you’ll need to first ensure your Application configuration is set to Persistent Content Type. If you have not done this the API request will fail with an error message indicating you have not yet configured your Application.

URI

POST /content/item/moderate/{contentItemId}

Table 1. Request Parameters

contentItemId [UUID] Required

The Id of the Content Item.

Table 2. Request Body

content [Object] Required

The piece of content being moderated.

content.applicationId [UUID] Required

The Id of the application that corresponds to the content source.

content.createInstant [Long] Required

The instant that the content was generated.

content.location [String] Optional

Specifies the location within the application that the content was generated. For example, you might use a chat room name, area Id for a game, or a thread Id for a forum. This parameter is used by CleanSpeak to display conversational views of content with the [Context View] feature.

content.parts [Array] Required

An array that contains one to many content parts. If your content only has a single part, such as a chat message, the array will only contain a single text entry. The reason you would send in multiple content parts within a single request is to ensure the moderation decision affects each part.

For example, you may send in an image for moderation, the image has a title and a description field. You would send this to CleanSpeak with three content parts, the image and two text parts. If the content of the image title is rejected the entire content needs to be rejected wholesale, the title, description and the image. In this case it would make sense to treat all three parts as an atomic unit of content.

If individual content parts are not related and can be rejected or approved separately then you should send them to CleanSpeak as separate requests.

content.parts[x].content [String] Required

The content to be filtered. This is a publicly reachable url to the content.

content.parts[x].name [String] Optional

The name of the content part. This value is optional an intended to better identify the context when you have more than one content part. For example this could be Title, Message Body or Image.

content.parts[x].type [String] Required

The type of this content part. Use image for this filter.

Other possible values:

  • text

content.receiverDisplayName [String] Optional

The display name of the user that received the content. This parameter should only be set if this piece of content was a private message between two users.

content.receiverId [UUID] Optional

The Id of the user that received of the content. This parameter should only be set if this piece of content was a private message between two users.

content.senderDisplayName [String] Optional

The display name (username or whatever is displayed to other users in the game/forum) that generated the content.

content.senderId [UUID] Required

The Id of the user that generated the content. This parameter is required so that CleanSpeak can analyze and associate the content with the user that generated it.

moderation [String] Optional

Tells CleanSpeak to forcibly put the content into a queue (Approval, User Alert or Content Alert). This overrides the configuration you have setup for the Application in the Management Interface.

  • requiresApproval
