PRISMS - European research project on privacy, security and public trust
PRISMS was a European research project focused on the relationship between privacy, security, surveillance technologies and public trust. The project examined whether security and privacy should be treated as a simple trade-off, or whether a more integrated and evidence-based approach is needed when evaluating security technologies.
The full project title was The PRIvacy and Security MirrorS: Towards a European framework for integrated decision making. PRISMS brought together perspectives from technology assessment, law, social science, criminology, policy research and public opinion studies.

Project overview
| Project acronym | PRISMS |
|---|---|
| Full title | The PRIvacy and Security MirrorS: Towards a European framework for integrated decision making |
| Main research area | Privacy, security, surveillance technologies, public trust and fundamental rights |
| Research context | European security research |
| Key idea | Studying how security technologies can be assessed together with privacy, legality, proportionality and social acceptance |
What was PRISMS about?
PRISMS addressed one of the most important questions in modern digital society: how should democratic societies balance security needs with the protection of privacy and fundamental rights? The project questioned the simplified idea that more security automatically requires less privacy.
Instead of treating privacy and security as opposing values, PRISMS explored a more complex relationship. A security measure may be effective or ineffective, proportionate or excessive, transparent or opaque, trusted or rejected. The project therefore examined not only technologies themselves, but also the social, legal and political conditions under which they are introduced.
Research focus
The project considered several types of security and surveillance-related technologies, including systems used for monitoring, identification, risk assessment, public security and data analysis. It asked how such technologies affect citizens and how citizens perceive them.
PRISMS also analysed the role of trust. A system introduced by a trusted institution, with clear safeguards and transparent rules, may be perceived differently from a similar system introduced without explanation or oversight. Public acceptance depends not only on technical performance, but also on governance, proportionality and accountability.
Main themes
- Privacy - protection of personal data, autonomy and private life.
- Security - measures intended to protect people, infrastructure and institutions.
- Surveillance - technologies that observe, identify, track or classify individuals or groups.
- Trust - public confidence in institutions, technologies and decision-making processes.
- Integrated decision making - assessing technical, legal, social and ethical aspects together.
Why does PRISMS still matter?
The questions studied by PRISMS are even more relevant today. Biometric identification, artificial intelligence, predictive analytics, smart city systems, digital identity, online monitoring and cybersecurity tools all raise questions about the relationship between security and privacy.
Modern information systems can collect and process large amounts of data. They may improve safety and efficiency, but they can also create risks for privacy, autonomy, fairness and democratic oversight. PRISMS remains a useful reference point for thinking about these issues in a structured way.
Historical relevance
PRISMS belongs to a period in which European research increasingly recognised that security technologies cannot be evaluated only by technical effectiveness. A system that is technically capable may still be problematic if it lacks legal safeguards, transparency, proportionality or public trust.
The project is therefore relevant not only for researchers, but also for policymakers, system architects, cybersecurity specialists, data protection professionals and anyone interested in the social consequences of digital security technologies.
