To prepare the training data, vFL needs to identify the common data entities shared by all parties. It is usually achieved by Private Set Intersection (PSI) which identifies the intersection of training samples from all parties by using personal identifiable information (e.g. email) as sample IDs to align data instances. As a result, PSI would make sample IDs of the intersection visible to all parties, and therefore","authors_text":"Aonan Zhang, Chong Wang, Jiankai Sun, Junyuan Xie, Weihao Gao, Xin Yang, Yuanshun Yao","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-06-10T05:26:50Z","title":"Vertical Federated Learning without Revealing Intersection Membership"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2106.05508","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":"sha256:4ace923c4a92f736687ca9da7910c409d92a9752ea73dc118c7d43ca2e39ac54","target":"record","created_at":"2026-07-05T02:48:02Z","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":"f725b7b75845d1344e30697d0631ae239ed12733ba44162df376d083f81e5775","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-06-10T05:26:50Z","title_canon_sha256":"6d4719d2c43650ff69dbde8ce11e3b6f6878fa820b314b381d6ee160494c3d1e"},"schema_version":"1.0","source":{"id":"2106.05508","kind":"arxiv","version":1}},"canonical_sha256":"144a23804c852569717683da35a011fa998da10f95e486658638cbc49eddbdc2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"144a23804c852569717683da35a011fa998da10f95e486658638cbc49eddbdc2","first_computed_at":"2026-07-05T02:48:02.557786Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:48:02.557786Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UxkCJlq4Y1IOzxNQZqirinLsFTQ8M9LIpLnr2W6evh/zi2l7S4CiUTW5tNev/QEQBZwfcLAeDA9m6vnICGMNDA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:48:02.558306Z","signed_message":"canonical_sha256_bytes"},"source_id":"2106.05508","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4ace923c4a92f736687ca9da7910c409d92a9752ea73dc118c7d43ca2e39ac54","sha256:f4e0ddec25a69f6a1f9b58c155964c633156474c50dc892cf76e0cd91697ce34"],"state_sha256":"b317eb695c22b28945a9434f8fcbc89e3f1dd71f05ff1cf7568aa1d0172be193"}
