Providing statistical disclosure risk assessments to protect privacy
Large data breaches have occurred. These breaches cause growing concern about the mosaic effect in which disparate pieces of information become significant when combined with other types of information on individual privacy.
This escalates disclosure risk by putting personally identifiable information (PII) into the public realm, which makes the mosaic effect very real.
The National Center for Science and Engineering Statistics (NCSES) asked Westat to review its data dissemination products to evaluate their risks.
