Automated Data Anonymisation Framework for Human Resources
Hello Radius is an AI-powered hiring platform that accelerates and secures recruitment by using skill-matching and anonymisation technology to reduce bias and protect candidate data. The company needed a reliable way to anonymise sensitive data in candidate CVs, such as names, addresses, and phone numbers, to ensure compliance with data privacy standards and reduce hiring bias. The challenge was to anonymise this information accurately while preserving key qualifications, skills, and experience essential for fair candidate evaluation.
NCC Cyprus offered consultation services to Hello Radius, which focused on investigating a range of tools for effective data anonymization. Microsoft Presidio and LangChain provided good candidate solutions, due to their strong capabilities in detecting and anonymising sensitive data. The integration of these tools could provide a solution that safeguards personal information while keeping valuable, non-identifying data intact.
“This project strengthened our technical capabilities, enhancing data privacy compliance, reducing risk and supporting our mission to make AI-powered recruitment safer and fairer. The team’s expertise helped us overcome a key AI development challenge with benefits extending beyond our immediate use case.”
