5. Conclusions
5.1. Complementary or conflicting rights?
The relationship between privacy and data protection is in many ways symbiotic. Protecting privacy implies the collection of less data, which is in line with data minimisation principles. Conversely, ensuring sufficient data protection protects privacy, as information about the individual is not subject to unauthorised disclosure. Interestingly, sensor systems illustrate a potential for conflict between two competing rights, resulting from the development of data protection as a right separate from privacy in a broader sense. Sensor systems do of course protect additional values beyond data protection, such as the security of public information systems and the integrity of government information resources. However, as this article illustrates, there is a growing momentum of positive data protection obligations acting as a potential driver for the deployment of such systems. In doing so, privacy and data protection may become values that largely need to be balanced against each other.
This further implies a tension within EU-law itself, as the CJEU has proven a watchful guardian of privacy in the face of wide-scale legislative encroachments from the EU through, inter alia, the DRD and the Safe Harbor agreement. Meanwhile, EU policy makers continues to push for improved network security through the NIS-directive, which may call for measures such as sensor system to be deployed as industry standards are developed, while simultaneously the entry into force of the GDPR implies an increased need to demonstrate sufficient technical and organisational measures to ensure protection of sensitive data.
