The principle of transparency in data protection law is no longer explicitly mentioned in the revised DSG; however, according to Art. 6 para. 3 FADP, data may only be collected for a purpose that is recognizable to the affected person. Moreover, the principle of transparency corresponds to the principle of good faith (Art. 2 CC), which applies to all areas of Swiss law. Data collection and processing must generally be carried out in a way that is known to the affected person. If this is not the case, the affected person cannot assert their rights. This also includes that the affected person is informed about the purpose of data collection. This may not be changed without the affected person’s renewed consent (s. below principle of purpose limitation).
