Le grand écart? 
La vie privée sur internet vue par les adolescents et leurs parents
The rising popularity of social media platforms among teenagers and the role they are taking as an integrated part of their daily communication has and will continue to raise a number of questions around the concept of security, and more precisely, about online privacy. This research paper aims to explore and compare the perceptions about online privacy in the digital era, first from the point of view of teenagers between 14 and 15 years of age, and then from the point of view of their respective parents. The first step in the data collection process was to ask the students to complete a survey about their online habits and the type of content they publish and share online.  In the second part of the research, face-to-face interviews were conducted, first with the teenager alone, then with the parents. The objective was to get a better understanding of the household’s dynamics and to observe the differences in the perception of online privacy. To begin, the data collected has shown significant discrepancies in the online behaviour of teenage girls versus boys. However, the results did not provide any statistical significance in online behaviour in respect to household regulations regarding the use of online communication tools. Furthermore, though widely influenced by personal experience, the interviews with different family members brought up fairly similar definitions of online privacy. The notion of gradation of values has also been approached in their definitions.
