Statistical Data Uniqueness

Meaning

Statistical Data Uniqueness is a quantitative measure that describes the degree to which a specific combination of non-identifying data attributes within a dataset is unique to a single individual. In the context of hormonal health data, this means that even after direct identifiers are removed, a highly specific combination of clinical biomarkers, age, and geographic location may be rare enough to statistically pinpoint one person. This metric is a crucial risk factor in data privacy, as high uniqueness indicates a greater vulnerability to re-identification attacks and a potential for data anonymization failure.
