Bounded-Retrieval Model with Keys Derived from Private Data

The Bounded Retrieval Model (BRM) was proposed at TCC 2006 (independently by Dziembowski and Di Crescenzo et al.). Essentially, the main idea of this model is to design cryptographic schemes with secret keys that are so large that it is infeasible for the adversary to steal them. One of the main technical problems of this idea is that it by definition requires the users to store large amounts o...

ABACUS: A Distributed Middleware for Privacy Preserving Data Sharing Across Private Data Warehouses

Recent trends in the global economy force competitive enterprises to collaborate with each other to analyze markets in a better way and make decisions based on that. Therefore, they might want to share their data with each other to run data mining algorithms over the union of their data to get more accurate and representative results. During this process they do not want to reveal their data to...

Securing Data Warehouses from Web-Based Intrusions

Decision support for 24/7 enterprises requires 24/7 available Data Warehouses (DWs). In this context, web-based connections to DWs are used by business management applications demanding continuous availability. Given that DWs store highly sensitive business data, a web-based connection provides a door for outside attackers and thus, creates a main security issue. Database Intrusion Detection Sy...

Private Multi-File Retrieval From Distributed Databases

Suppose there are N distributed databases each storing a full set of M independent files. A user wants to retrieve r out of the M files without revealing the identity of the r files. When r = 1 it is the classic problem of private information retrieval (PIR). In this paper we study the problem of private multi-file retrieval (PMFR) which covers the case of general r. We first prove an upper bou...

Solutions for improving data extraction from virtual data warehouses

The data warehousing project’s team is always confronted with low performance in data extraction. In a Business Intelligence environment this problem can be critical because the data displayed are no longer available for taking decisions, so the project can be compromised. In this case there are several techniques that can be applied to reduce queries’ execution time and to improve the performa...
