Secure Statistical Analysis of Distributed Databases, Emphasizing What We Don't Know

"Secure" Log-Linear and Logistic Regression Analysis of Distributed Databases

The machine learning community has focused on confidentiality problems associated with statistical analyses that “integrate” data stored in multiple, distributed databases where there are barriers to simply integrating the databases. This paper discusses various techniques which can be used to perform statistical analysis for categorical data, especially in the form of log-linear analysis and l...

Secure, Privacy-Preserving Analysis of Distributed Databases

There is clear value, in both industrial and government settings, derived from performing statistical analyses that, in effect, integrate data in multiple, distributed databases. However, the barriers to actually integrating the data can be substantial or even insurmountable. Corporations may be unwilling to share proprietary databases such as chemical databases held by pharmaceutical manufactu...

Computationally secure multiple secret sharing: models, schemes, and formal security analysis

A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. Up to now, existing MSSs either require too long shares for participants to be perfect secur...

Anti-Vascular Endothelial Growth Factor Therapy in Pregnancy: What We Know, What We Don't Know, and What We Don't Know We Don't Know.

Secure Regression on Distributed Databases

This article presents several methods for performing linear regression on the union of distributed databases that preserve, to varying degrees, confidentiality of those databases. Such methods can be used by federal or state statistical agencies to share information from their individual databases, or to make such information available to others. Secure data integration, which provides the lowe...
