During their browsing, web users transmit, deliberately or not, personal data and usage data.
They can be identified by various actors (GAFAM, institutions, individuals, …), and the users’ private life is no longer private. Even their consumption habits, political or sexual preferences can be known.
Observing the multiplicity of modalities blurring the use of data on the web, I propose to alert the younger users who are not always aware of the potential danger of sharing their personal data. This awareness is part of mediation workshops, based on a fun game incorporating Instagram and its content, to make them more attentive to what they publish or transmit involuntarily on the web.
