Essentials
Re-identification risk in business data
By SourceX Editorial · Updated
Short answer
Re-identification happens when removed details can be pieced back together. It's lowered by removing indirect identifiers, generalizing rare facts, reviewing samples and banning re-identification in the license.
Indirect identifiers#
Job titles, dates, locations and rare events can identify people in combination.
Controls#
Generalize, exclude, review and contract.
How SourceX handles it#
SourceX starts with a short fit check that shares no data. If it fits, rights are reviewed, a copy is prepared with personal and confidential details removed, and your company approves exactly what leaves before anything is delivered under a signed license.
Frequently asked questions
Who is liable if someone re-identifies data?
The license puts that responsibility on the buyer; counsel confirms the details.
Is this legal advice?
No. It is general information; your counsel should review any specific deal.
