Abstract: For the uncertainty decision-making problem of privacy risk, based on the theories of intuitionistic fuzzy and set pair analysis, a set pair relationship of information weights is established for privacy certainty & uncertainty. The intuitionistic fuzzy set pair operator is provided, and the relevant concepts, operations, properties, expected values, size ranking, and several intuitionistic fuzzy set pair information aggregation operators are defined, including Intuitionistic fuzzy set pair analysis operators, intuitionistic fuzzy set pair analysis weighted average operators, intuitionistic fuzzy set pair analysis weighted geometric operators, intuitionistic fuzzy set pair analysis ordered weighted average operators, intuitionistic fuzzy set pair analysis ordered weighted geometric operators, intuitionistic fuzzy set pair analysis hybrid aggregation operators, intuitionistic fuzzy set pair analysis hybrid geometric operators and their related properties. On this basis, the intuitionistic fuzzy set pair information aggregation method for privacy risk multi-attribute decision-making is analyzed, and it shows that the proposed method has feasibility and rationality.
