Privacy score: Making privacy aspects of surveillance systems comparable

When authorities are faced with a security problem and decide to install surveillance technology they have to decide on a multitude of questions. Which technology to use? Which different implementations of that technology exist on the market? What is the potential privacy impact of the different solutions? What are the costs (financial and privacy) relative to the benefits? Without expert knowledge it is hard to detect where privacy risks emerge and what can be done to prevent or mitigate them. To aid the authorities in this process and guarantee that privacy protection is a relevant part of the decision privacy score was created. Privacy score rates data protection of surveillance systems. To rate an implementation an auditor has to answer nine different questions in three categories: ""Data collection"", ""Data access and use"" and ""Technical data protection"". The result is a privacy score between 0 and 21 points that can be used as basis for further analysis.
