It is a widely popular notion of privacy since it captures the natural privacy semantics for many applications (such as, for location data) and results in better utility than standard DP. However, prior work in metric DP has primarily focused on the item-level setting where every user only reports a single data item. A more realistic setting is that of user-level DP where each user contributes multiple items and privacy is then desired at the granularity of the user's enti","authors_text":"Amrita Roy Chowdhury, Jacob Imola, Kamalika Chaudhuri","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CR","submitted_at":"2024-05-04T13:29:11Z","title":"Metric Differential Privacy at the User-Level Via the Earth Mover's Distance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.02665","kind":"arxiv","version":2},"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:e9225ec9a560480423b9386d9e3b66c894c5584952cb7ed120d1abc58a8dcd96","target":"record","created_at":"2026-07-05T09:17:41Z","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":"bf9ae2d81284862dde7c420b4582ced6368c26cec8da06a69b8607c4b4329340","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CR","submitted_at":"2024-05-04T13:29:11Z","title_canon_sha256":"476b29f0f135297598a4a4535e59dbfccecb37fb67ef3c965260daf4c3a59780"},"schema_version":"1.0","source":{"id":"2405.02665","kind":"arxiv","version":2}},"canonical_sha256":"b52ee8c216c6a66f21e42984951f11dcaf9cb94f6fc13004fc3a034460733470","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b52ee8c216c6a66f21e42984951f11dcaf9cb94f6fc13004fc3a034460733470","first_computed_at":"2026-07-05T09:17:41.184609Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:17:41.184609Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wKV4GKXhi3dMtnrczp3qgV/Wqe0Kc79l/5JEmvT3zMLxRoITC1P+fyZ5GtanTYV8Genp/SI2D4z94R6qmomWCw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:17:41.185090Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.02665","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9225ec9a560480423b9386d9e3b66c894c5584952cb7ed120d1abc58a8dcd96","sha256:61b506562fd8a273d230c11cf9140820835440b16b335341e48a4ff69ea4db59"],"state_sha256":"d260bef5d51316ce47616e8e18558d9d5a6c3b636ae679c82afc967a349c35a4"}
