The MediaModeration extension is for detecting possible child exploitation content.
The purpose of the extension is to improve the Foundation’s existing workflows for child protection content.
Prior to deployment of this extension, when the Foundation receives a report of images that depict child sexual abuse, the images are deleted from the projects and reported to law enforcement according to legal requirements. This setup requires volunteers, who unlike staff have no professional training or mental health support, to initially deal with this very emotionally taxing content.
This extension aims to protect the community from being exposed to such content in nearly all cases and get it off the platform a lot faster. It would check images against a database of hashed, known images of child sexual abuse and notify Foundation staff of hash matches to allow Foundation staff to remove the images and report their existence to law enforcement.
This extension does not automatically remove any content without human review by Foundation staff.
MediaModeration provides the following:
- Check uploaded image against PhotoDNA
- Send email to pre-configured recipients if suspicious content found
Before installation, the PhotoDNA subscription key should be obtained from Microsoft.

|Configuration Variable||Default Value||Description|

||Key for access to PhotoDNA service endpoint, obtained from Microsoft. Must be given a value. Which is available from wmaint server:yourName@mwmaint1002:~$ mwscript shell.php --wiki=commonswiki Psy Shell v0.11.10 (PHP 7.4.33 — cli) by Justin Hileman|
||List of emails to be notified a hash match occurs. Must be an array. Must be given a value.|
