Identifying the Problem: Why Pseudonymization is Important for Data Privacy

Businesses want to run tests and statistical analysis on existing Google Sheets containing sensitive customer data. That sensitive data needs to be replaced with fake data (aka format-preserving pseudonyms) for the following reasons:

  • Productivity: Manually generating pseudonyms is time consuming work and is prone to typos or semantic errors that make the generated data unusable.
  • Compliance: GDPR, HIPAA, CCPA and many other privacy laws enforce all customer sensitive data to be accessed on a need-to-know basis. Removing data access for testing and analytic workload reduces compliance risk.
  • Security: Sharing updated sheets allow recipients to still access sensitive customer data because Google Sheets maintain a version history that tracks all changes. Also, insider attacks are common where employees who have access to customer's sensitive data lead to data exfiltration.

The Solution: Step-by-Step Guide on Pseudonymizing Data in Excel or Google Sheets or CSV with Strac
