Our criterion measured privacy risk as a divergence between the user's and the population's query distribution, and contemplated the entropy of the user's distribution as a particular case. In this work, we make a twofold contribution. First, we thoroughly interpret and justify the privacy metric proposed in our previous work, elaborating on the intimate connection between the celebrated method of entropy maximization and the use of entropies and divergences ","authors_text":"David Rebollo-Monedero, Javier Parra-Arnau, Jordi Forn\\'e","cross_cats":["cs.CR","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2011-11-17T10:06:49Z","title":"An Information-Theoretic Privacy Criterion for Query Forgery in Information Retrieval"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.4045","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5c507ad3230605e209978452d83545fac4d1833f311a8d0e9eaac4a4a298485c","target":"record","created_at":"2026-05-18T02:21:29Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"e3861e8e3e2b0ad021d6659493808c6145a6f600786eff6cadca4de973531adc","cross_cats_sorted":["cs.CR","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2011-11-17T10:06:49Z","title_canon_sha256":"83459403fe004545606df159f357c5ac599309562d8c4074f20e5083a83ed321"},"schema_version":"1.0","source":{"id":"1111.4045","kind":"arxiv","version":1}},"canonical_sha256":"7af489061aa159669fb5ebeed8d0b7e48c86435841b318ddc6984d7786e84cee","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7af489061aa159669fb5ebeed8d0b7e48c86435841b318ddc6984d7786e84cee","first_computed_at":"2026-05-18T02:21:29.176672Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:21:29.176672Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U3P2SgPr+gRD3LfnzU3pcrVhxlyuSh3rjKPTT+q//HXIVQlpm1RKVk7Zjc0G2jFp7Wz/S10r9lZEXE0/d8dCDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:21:29.177127Z","signed_message":"canonical_sha256_bytes"},"source_id":"1111.4045","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c507ad3230605e209978452d83545fac4d1833f311a8d0e9eaac4a4a298485c","sha256:519ffb2a50f9e700ae0277133e73dfde671ee302bfa8b98b3a31463638c352d8"],"state_sha256":"86d6688eb0b7d4e7cb1fa5ff2a5fb072ac40aaa229c8a6c1aa6c9544aeb62e00"}
