Privacy is a relevant concern in the intelligent systems environment, Internet of Things and Ubiquitous Computing, because of indiscriminate data collection and sharing practices, and the distancing of mental models between users and software designers. This paper articulates challenges for the establishment of privacy and proposes a method for eliciting privacy requirements in ubiquitous systems in order to think about privacy in the early stages of design, being a practice that cross through technology projects as a concern to be evolved along with the software artifacts. A use example of the method was performed, deriving privacy requirements for a travel-sharing application. Software artifacts were constructed from the requirements and were utilized in a participatory design session to project elements of privacy. At the end of the process, we obtained prototypes of medium fidelity focused from the beginning in privacy, articulating elements for its protection, configuration and comprehension by users.
