A taxonomy of requirements for the privacy goal transparency

Abstract

Privacy is a growing concern during software development. Transparency–in the sense of increasing user’s privacy-awareness–is a privacy goal that is not as deeply studied in the literature as the properties anonymity and unlinkability. To be compliant with legislation and standards, requirements engineers have to identify the requirements on transparency that are relevant for the software to be developed. To assist the identification process, we provide a taxonomy of transparency requirements derived from legislation and standards. This taxonomy is validated using related research which was identified using a systematic literature review. Our proposed taxonomy can be used by requirements engineers as basis to systematically identify the relevant transparency requirements leading to a more complete and coherent set of requirements.
