  Pervasive use of software applications continues to challenge user privacy
when users interact with software systems. Even though privacy practices such
as Privacy by Design (PbD), have clear in- structions for software developers
to embed privacy into software designs, those practices are yet to become a
common practice among software developers. The difficulty of developing privacy
preserv- ing software systems highlights the importance of investigating
software developers and the problems they face when they are asked to embed
privacy into application designs. Software devel- opers are the community who
can put practices such as PbD into action. Therefore, identifying problems they
face when embed- ding privacy into software applications and providing
solutions to those problems are important to enable the development of privacy
preserving software systems. This study investigates 36 software developers in
a software design task with instructions to embed privacy in order to identify
the problems they face. We derive rec- ommendation guidelines to address the
problems to enable the development of privacy preserving software systems.
