We build an analysis of contemporary identity devices (including social network sites) on several levels: computer (conceptual model ending social representations and sociability), microsocial (negotiating subjective singularities and anchoring social norms), economics (hegemonic strategies and partnerships with cultural industries), socio-political (experimenting individual postures based on emotional experiences in a « private club model » and making it possible to engage in deliberative processes constituting common sense). To understand these issues, we have implemented an immersive and multi-situated methodology located in a population composed of contemporary subject's figures: young apprentices in the Tertiary, subject to complex constraints, and committed personal level, social and professional identity in various devices. It is clear from these analyzes several theoretical proposals, including the « privatory framework » presented as a set of identity constraints defined or negotiated by interactants and situating in Computer Science (engineering publicized privacy), the micro (mutual insight), economic (socioeconomic model of the « private club »), socio-political (anecdotical sphere) and methodological (immersion to users).
