Image and Video Blurring overview

Updated

Image and Video Blurring uses AI to detect and obscure inappropriate or harmful visual content, helping safeguard students from exposure to gore, pornography and intimate apparel.

Key benefits

  • Supports compliance: Meets KCSIE guidelines, Online Safety Act and DfE standards for preventing access to obscene visual depictions.
  • Filters in real-time: Checks every image and video, no matter how recently it went live and regardless of any previous categorisation, leaving no gaps in which children can be exposed.
  • Customisable control: Lets you adjust sensitivity per category, plus automatic page-wide blurring and an allow list.
  • Prevent over-blocking: If a single image or video clip on an otherwise educational page is flagged as inappropriate, students can still access the rest of the content without blocking the entire URL.

Features

Content Categories

Turn detection and Image and Video Blurring on or off for these content categories:

  • Gore: Graphically violent content, including:
    • Beatings, mutilations, and decapitations
    • Victims of accidents and shootings
    • Self-harm and suicide
    • Blood and guts
    • War violence
    • Dead bodies
  • Pornography: Explicit and adult content, including Anime and cartoons.
  • Intimate Apparel: Content that objectifies people wearing specific types of clothing, including:
    • Swimwear and beachwear
    • Lingerie and underwear

Sensitivity level

Adjust the Sensitivity level to customise how confident Image and Video Blurring needs to be that the content fits into one of the Categories, in order to blur it. Select between Low, Medium or High.

  Note

At a higher Sensitivity level, there’s a higher chance of false positives, so appropriate images may be blurred.

Create allow lists of Excluded Domains or YouTube Channels

Allow access to approved exclusion lists to support curriculum needs (for example, content for Science, Art, or History). You can exclude as many domains and YouTube Channels as required with no limit, but you can’t upload a bulk list.

Automatic video block

When this setting is on, and a video plays five seconds of inappropriate content, the video and audio are stopped, the player is blurred, and the buttons and options are removed.

Guilt by Association

Guilt by Association automatically blocks visual content once the majority of images or video frames are identified as inappropriate.

Images:

  • If more than half of the first few images on the page are inappropriate, all images on the page will be blurred.
  • If fewer than half are inappropriate, Image Blurring will blur only those images and continue checking the next set of images on the page.

Videos:

  • If more than half of the first few frames of a video are inappropriate, the entire video will be blurred. Audio will still play.
  • If fewer than half of the frames are inappropriate, Video Blurring will blur only those frames and continue checking the next set of video frames.
