As children across Sussex return to school after the summer holidays, police have issued a stark warning to parents about the risks of posting back-to-school pictures online.

Sussex Police released an awareness video cautioning that a seemingly harmless photograph taken outside the family home can unintentionally reveal a wealth of private information. The footage demonstrates how details such as house numbers, street signs, school crests on uniforms, chalkboard messages, vehicle registration plates, name tags, and even wedding rings can be misused.

Officers warned that this data can be harvested and exploited using artificial intelligence tools to create illegal child abuse imagery or track a family's exact routine and location.

"Everyday family photos can be misused by AI tools to create illegal child abuse imagery," a Sussex Police spokesperson said. "There are steps you can take, many you may already be doing, to protect your family and friends."

The force urged parents to carefully review what is visible in the background of images before sharing them online.

The Instagram post containing the warning attracted hundreds of comments and thousands of shares. Some commenters expressed concern about the force's use of AI in the video. Responding to one comment, Sussex Police explained: "That's correct. We've used an AI-generated image for this post. We chose not to use photographs of real children because the post discusses online image safety and how emerging technologies can use images shared online. Using AI allowed us to illustrate the message while protecting the identity and privacy of real children."

The Internet Watch Foundation, a UK charity dedicated to eliminating child sexual abuse imagery online, has offered practical advice for parents. Recommended steps include:

  • Blur or crop identifiers: Remove house numbers, street signs, school logos, and car number plates before uploading photos online.
  • Keep details off display: Avoid using personalised name tags or chalkboards that state your child's age, teacher, or exact school name.
  • Check privacy settings: Ensure your social media accounts are strictly set to private.
  • Turn off location tagging: Disable automatic geotagging on your phone's camera app.
