Nowadays, personal context is extensively used in personalized mobile services. However, gathering this kind of information may compromise the privacy of the user. Moreover, the number of services that collect and share the personal context with others is growing. Yet, the users are not able to easily control what information is shared and with whom. An important step towards this goal is to understand how and when the user wants to share his personal context. The literature suggests that the willingness to disclose personal information depends on the level of intimacy perceived in given contexts. In this paper we show how the MDC data enabled us to estimate the level of intimacy of the user in a given contexts of his/her daily life.
