This study introduces a remote analysis server to enable research on private data while minimizing disclosure risk. This approach allows statistical analysis without releasing sensitive individual information, balancing data utility and privacy protection.

Area of Science:

  • Computer Science
  • Statistics
  • Data Privacy

Background:

  • Research and policy analysis often require sensitive data, posing challenges for confidentiality and privacy.
  • Traditional methods like data de-identification or modification can limit data utility.
  • Protecting individual privacy while enabling data analysis is a critical challenge.

Purpose of the Study:

  • To present a novel approach for analyzing confidential data remotely.
  • To reduce the risk of sensitive information disclosure during data analysis.
  • To enable a wide range of statistical analyses on private datasets.

Main Methods:

  • Utilizing a remote analysis server that does not release data.
  • Implementing techniques to lower the risk of inferring individual record attributes.

  • Developing a software demonstrator, Privacy-Preserving Analytics (PPA), with a web-based R interface.

    • Main Results:

    • The remote server delivers useful results from user-specified statistical analyses with low disclosure risk.
    • The system supports various analytical methods including exploratory data analysis, regression, and survival analysis.
    • Demonstrated effectiveness using biostatistics examples with publicly available data.

    Conclusions:

    • The remote analysis server offers a viable solution for balancing data utility and privacy.
    • The Privacy-Preserving Analytics (PPA) system provides an effective tool for secure data analysis.
    • This method reduces disclosure risk, enabling broader use of sensitive data for research and policy.
