The existing randomized response for this purpose uses the Kronecker product to perturb each attribute information in turn according to the respective privacy level but achieves only a weak privacy level for the entire dataset. Therefore, we first describe a privacy-optimized randomized response that guarantees the strongest privacy in sharing multi-attribute data.
