Case Study: Health and Safety Executive achieves GDPR-safe anonymisation at scale with Ohalo Data X-Ray

HSE anonymizes 600,000 documents in 1 machine-day with Ohalo

The UK's Health and Safety Executive (HSE) faced the immense challenge of anonymizing 600,000 safety records to enable data sharing without risking GDPR violations. Manually redacting the mixed-format documents would have taken an estimated 12.5 person-years, a task that was untenable in terms of budget and staffing. HSE turned to vendor Ohalo and its Data X-Ray solution to automate this redaction and anonymization process accurately and at scale.

Ohalo's Data X-Ray automated the identification and anonymization of sensitive information, achieving over 99% accuracy. The solution completed the entire job in just one machine-day, a time reduction of 4,500x compared to manual processing, while also delivering a 49x cost saving. This enabled HSE to safely share and analyze data at scale while ensuring GDPR compliance, establishing an efficient and scalable model for future data desensitization.
