Senate Matching is the name of Data Republic’s privacy-preserving matching technology which allows organizations to match datasets without exposing personally identifiable information (PII). 

Senate Matching is a SaaS offering which is fully integrated with the Senate platform. Data owners do not pay an additional fee to utilize Senate Matching as part of a Senate Project. 

How it works

Senate Matching software called a Contributor Node is installed behind your organization’s firewall. 

Data Custodians prepare data by uploading it into the Contributor Node which strips personal information fields and replaces identifiers with randomly generated tokens. 

These randomly generated tokens then undergo a process of non-reversible hashing, salting and slicing before being distributed to nodes on the Senate Matching Network for future match requests.

Matching activities are governed as part of projects on the Senate platform and require both the consent of the Data Custodian as well as an approved license. Matches are performed through a series of calls across the matching network where the hashed, token slices are verified.  

Using this technology, customer personal information never leaves the data owner organization in its complete form. Analysts in workspaces never receive PII, only tables which indicate where a match has occurred against one of their own tokens. The decentralized matching methodology also makes it virtually impossible to re-identify a customer. 

Senate Matching allows Data Republic users to realize the true potential of collaborative customer analytics while protecting customer PII and privacy.
