Software systems handle more and more sensitive information concerning citizens. It is important that such systems are privacy-friendly by design. In previous work, we proposed a privacy threat analysis methodology, named LINDDUN. The methodology supports requirements engineers and software architects in identifying privacy weaknesses in the system they contribute to developing. As this is a fairly new technique, its results when applied in realistic scenarios are yet unknown. This paper presents a series of three empirical studies that thoroughly evaluate LINDDUN from a multi-faceted perspective. Our assessment characterizes the correctness and completeness of the analysis results produced by LINDDUN, as well as the productivity associated with executing the methodology. We also look into aspects such as the ease of use and reliability of LINDDUN. The results are encouraging, overall. However, some areas for further improvement have been identified as a result of this empirical inquiry.en0164-12122014122138ElsevierEmpirical studyPrivacyThreatsInformatikJournal Article10.1016/j.jss.2014.05.075Other
