What We Proudly Share About Our Children — and Who Else Is Watching…
Why the things children and families share online reveal more than many realize — and how parents can better protect themselves and their children.
When parents think about dangers on the internet, they often imagine strangers in chat rooms, harmful content, or too much screen time. What is frequently overlooked is that the real risk often starts much earlier — with the information we and our children share every day.
- A photo from a birthday party.
- A gaming username.
- An email address for a school platform.
All of it seems harmless. But for others, it can be the beginning of a much bigger story.
The Invisible Puzzle
There is a discipline that describes exactly this process: Open Source Intelligence (OSINT).
Originally rooted in military and intelligence work, OSINT is now widely used by companies, journalists, and security agencies - but also by criminals.
The idea is simple: publicly available information is systematically analyzed to generate insights.
Or more simply put: data becomes knowledge.
And that knowledge can be used for good - or against us.
How Small Clues Become a Full Picture
In digital investigations, it becomes clear again and again how quickly isolated pieces of information can turn into a complete profile. A single starting point - such as an email address, phone number, or username - is often enough.
Within minutes, additional details can emerge:
- linked accounts across multiple platforms
- previous usernames
- publicly visible interests and hobbies
- possible locations
- and even connections to family members
What matters most: these details are usually not “hacked.” They are publicly accessible - simply connected together.
This is exactly what OSINT is about: systematically collecting and analyzing openly available data.
These methods are valuable and necessary in security, investigations, and background checks. But the same techniques are also used by attackers — and with artificial intelligence, this analysis now happens in seconds.
That changes the conversation entirely. It is no longer just about what we share, but about what others can do with it.
And if this works for adults, it works for children too.
When Information Creates False Trust
For children, this is especially difficult to recognize. If someone appears to share the same interests, knows their favorite sports club, or mentions the name of their school, it feels familiar - almost like coincidence.
In reality, it may simply be the result of targeted research.
A child might receive a message like:
“Hey, don’t you go to the same school as my cousin? I saw your profile 😊”
To a child, this can feel friendly and trustworthy.
To adults, it is often clear that someone may be intentionally using information to build trust. And that is where the real danger begins.
Why Families Are Especially Exposed
Families are particularly easy to analyze online because their digital traces form networks rather than isolated profiles.
Parents follow their children, like posts, comment on photos, and share moments from family life. Schools, sports clubs, and friend groups create additional connections.
As a result, individual accounts become a connected relationship map.
Publicly visible information can easily be combined:
- first day of school photos
- sports club posts
- comments on friends’ profiles
- vacation pictures
The issue is often not a single post - but the relationships between all the information.
Step by step, outsiders can build a surprisingly accurate picture:
- the child’s approximate age
- school, clubs, and social circles
- family relationships and routines
- recurring locations and habits
Not because one piece of information is highly sensitive on its own - but because all the details confirm and strengthen each other.
When Trust Is Exploited
These connected digital profiles create risks that are still discussed far too rarely:
- Grooming: adults intentionally building trust with children
- Sextortion: children being manipulated, pressured, or blackmailed
- Social engineering: parents themselves becoming targets of manipulation
The dangerous part is that these interactions often do not feel suspicious. The people behind them appear friendly, relatable, and familiar.
Artificial intelligence makes this even more convincing.
Profiles can be generated automatically. Messages sound more personal. Images and voices can be faked realistically. For children - and even adults - it becomes increasingly difficult to distinguish genuine contacts from fake ones.
That is why “Don’t talk to strangers online” is no longer enough. Many strangers no longer appear strange at all.
What Parents Can Do
Share More Carefully
Not everything needs to be public. Before posting photos, ask: What is visible? A school? A location? A club logo?
Involve Children
Instead of only setting rules, encourage awareness:
“What could someone learn about you from this?”
Reduce Digital Traces
- avoid combining real names with birth years
- use different usernames across platforms
- review location and photo settings
Keep Communication Open
Children should know that not everything online is harmless - and that they can always talk to their parents if something feels wrong.
Conclusion
We share because we are proud.
Because we want to preserve moments.
Because we want to stay connected.
But in a world where information can be analyzed within seconds, even one small detail can contribute to a much larger picture.
Not everything visible online is harmless. And not everyone who seems interested has good intentions.
When parents understand how complex profiles can be built from individual pieces of information, they can make more conscious decisions about what to share — and what is better kept private.
Because online safety does not begin with internet rules. It begins with a simple question:
What are we revealing about ourselves - and who is watching?
Note on Workshops
To make these topics more understandable and practical, Stephanie Böhm (CEO of Norphluchs GmbH, specializing in Open Source Intelligence) and Simon Degenkolb (CEO of INTRA Investigations AG, specializing in digital investigations and analysis) offer hands-on workshops for families.
The workshops explain how publicly available information is analyzed, how digital profiles are created, and what practical protective measures families can take in everyday life - with real-world examples and room for discussion.
