Digital intrusion and personal data management: cognitive processes, dynamics and evolution over time[Intrusion numérique et gestion des données personnelles : processus cognitifs, dynamiques et évolutions dans le temps]

Over the last few years, connected objects have been invading our daily lives. By greatly facilitating the collection and exploitation of personal data, they are sources of concern for consumers. In this context, a longitudinal qualitative methodology was implemented to study the cognitive processes of participants who were placed in a situation of intrusiveness within an experimental apartment . Results show that, these technologies can promote a sense of physical, financial, social and psychological well-being. But we also observe recurrent (questioning related to the interpretations and uses of the collected data) and punctual sources of stress (negative social influences and technological dysfunctions). In order to be controlled, coping strategies such as a need for reassurance are developed by the participants. Finally, these few fears don't call into question the overall confidence of the participants, but they highlight a real need for explanation and transparency on the insights learned from the data collected.
