Privacy Issues for K-Anonymity Model
K-anonymity is the approach used for preventing identity disclosure. Identity disclosure means an individual is linked to a particular record in the published data and individual's sensitive data is accessed. Some important information such as Name, Income details, Medical Status and Property details are considered as a sensitive data(or Attribute) because these data have to be kept secure from unauthorized access. Generally these details are stored in private tables of any organization or committees. Some released attributes called as quasi identifiers (Zip code, Sex, marital status, Age, Date of Birth, Bank details) when linked with private table cause the Identity disclosure.
