How To Match 3 Billion Records Without Revealing Identifiers

A Behind-the-Scenes Look At A Global, High-Speed Data Collaboration; Powered By Protected Data Pipelines

2 billion records matched to 1 billion. 
Results delivered in under 20 hours. 
No PII exchanged. No centralized environment. No delays. 

Just fast, secure, partner-friendly collaboration at scale. 

"The overlap analysis process for evaluating new partners, fraught with big data and compliance challenges, has been streamlined significantly thanks to our collaboration with Karlsgate. This partnership has allowed Eyeota to evaluate potential new data partnerships – without either party having to physically transfer data – more efficiently and bring new data assets to market more quickly."  

                          Jess Saunders, VP, Global Partner Success, Eyeota, a Dun & Bradstreet company

This wasn’t a moonshot. It was a proof point. 
And it’s setting a new bar for how data collaboration can (and should) work. 


The Old Way Would Have Stalled Out

Ask anyone who’s tried to coordinate a large-scale, cross-border data collaboration, and they’ll tell you. It’s rarely fast, and almost never easy. 

Legal friction, privacy concerns, technical mismatches, and trust barriers all slow things down. These issues only get harder when billions of records and multiple jurisdictions are involved. 

Most teams still assume that to get meaningful results, someone must give something up: 

  • Share personal identifiers and accept the exposure risk 
  • Centralize data, which means losing control and increasing your risks 
  • Wait weeks for each new partner, repeating the same legal, security, and technical processes again and again 

That’s what makes this project different. 
None of those compromises were necessary. 


The Breakthrough: Protected Data Pipelines 

What changed? The data stayed protected from start to finish. 

Each side used their own Karlsgate Identity Exchange (KIE) node to locally create cryptonyms, replacing identifiers with one-time-use keys. Nothing left the environment in identifiable form, and no centralized entity ever touched the source data. 

Only the match result, de-identified, permissioned, and encrypted, was shared. 

What KIE enabled: 

  • Ultra-fast execution: Less than 20 hours from start to finish 
  • High-fidelity matching: Accurate, consistent, flexible, and trustworthy 
  • Complete data control: No source files or raw identifiers sent to a third party 
  • Global regulatory compliance: Meets privacy and InfoSec requirements across jurisdictions 

KIE is privacy-preserving, operationally efficient, and cost effective. 


The Future of Collaboration Starts Here 

Data doesn’t need to be visible to be useful, and it doesn’t need to be centralized to be connected. 

When protection is built into your operation workflows, privacy reviews happen once, compliance becomes automated, and partnerships scale without compromise. 

This collaboration proved it. And it’s only the beginning.
