NCorr-FP: A Neighbourhood-Based Correlation-Preserving Fingerprinting Scheme for Intellectual Property Protection of Structured Data

NCorr-FP is a data fingerprinting (embedding hidden recipient-specific marks into data to track ownership) technique designed to protect structured tabular data in shared environments. The method preserves the statistical quality of data while embedding fingerprints using local record similarity and density estimation, and can detect these fingerprints even after substantial data modification or deletion attacks.
