WITDOM Data Masking

WITDOM’s data masking component is responsible for masking sensitive data classified as direct identifiers. The masking process creates service-and-user-specific tokens that can be updated over time, satisfying two main security requirements: irreversibility and unlinkability.

(Note: WITDOM is part of TRUSTEE (daTa pRivacy and cloUd SecuriTy clustEr Europe), a network of 11 research projects funded by the European Union which are all performing cutting-edge research and innovation in different domains of cloud security and privacy, ranging from secure and privacy-friendly authentication over encrypted and distributed solutions for data sharing and cloud storage to data integrity, authenticity, and availability.)
