One-sided Differential Privacy

Doudalis, Stelios, Kotsogiannis, Ios, Haney, Samuel et al.

Understand

In this paper, we study the problem of privacy-preserving data sharing, wherein only a subset of the records in a database are sensitive, possibly based on predefined privacy policies.

  • Existing solutions, viz, differential privacy (DP), are over-pessimistic and treat all information as sensitive.
  • Alternatively, techniques, like access control and personalized differential privacy, reveal all non-sensitive records truthfully, and they indirectly leak information about sensitive records through exclusion attacks.
  • Motivated by the limitations of prior work, we introduce the notion of one-sided differential privacy (OSDP).
