What the report examines
A multidisciplinary analysis of the EU proposal on online child sexual abuse, addressing general monitoring, proportionality, private communications, adolescent sexual exploration, voluntary detection and institutional safeguards.
- Examines whether detection obligations engage the prohibition of general monitoring and how Article 52 of the EU Charter should discipline the proposal’s proportionality analysis.
- Addresses consensual online sexual exploration between adolescents, age verification, end-to-end encryption, voluntary detection and the relationship between the proposed EU Centre and EUROPOL.
- Records areas of common ground on risk assessment, child-friendly reporting, less intrusive measures, independent institutional design, law-enforcement capacity and children’s participation.
Publication context
