Moodle plugin that adds watermarks to input text fields and the background on quiz attempt pages.
This may help to identify who copied answers from whom.
Important: This plugin is only a prototype/demonstration. We will probably not maintain this repository in the long-term.
This plugin requires Moodle 3.9+ and PHP 7.4+.
Install the plugin by copying the code to
mod/quiz/accessrule/watermark.
You also need to apply the patch questionattempt.patch.
