Data Owner Tools

Tools for Clinical and Community Data Initiative (CODI) Data Owners to extract personally identifiable information (PII) from the CODI Data Model and garble PII to send to the linkage agent for matching. These tools facilitate hashing and Bloom filter creation part of a Privacy-Preserving Record Linkage (PPRL) process.

This software package is specifically for use by CODI "Data Owners" and "Data Partners" to garble their data, which is then sent to a Linkage Agent, a third-party organization that links the hashes (see "PPRL Overivew/CODI Roles" in the wiki for more information). To view the software package used by the CODI Linkage Agent, see Linkage Agent Tools.

For more information about PPRL and CODI, visit the wiki: https://github.com/mitre/data-owner-tools/wiki/PPRL-Overview
