However, most of existing works only consider the federated learning scenario where data are partitioned by samples. The feature-partitioned learning can be another important scenario since in many real world applications, features are often distributed across different parties. Attacks and defenses in such scenario are especially challenging when the attackers have no labels and the defenders are not able to access the data and mo","authors_text":"Tianjian Chen, Yang Liu, Zhihao Yi","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2020-07-07T16:45:20Z","title":"Backdoor attacks and defenses in feature-partitioned collaborative learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2007.03608","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":"sha256:4770c874bd81dad91f3943c5b9f73edde17614dc07b6f2d1e6c489210fc33d8c","target":"record","created_at":"2026-07-05T01:17:04Z","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":"2aa9fae7e7bd8fc89911be370552b4abf16b69e083a1f777c7d709e9e00163e3","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2020-07-07T16:45:20Z","title_canon_sha256":"f8e2187ef058aff9267b83788ef6e9890ca68a164d2e7d2fe796952e5612ef38"},"schema_version":"1.0","source":{"id":"2007.03608","kind":"arxiv","version":1}},"canonical_sha256":"168b2ccb144626c2a4d7554c6d37ec1ce87230f1ded0937ecbbb24c575d3025d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"168b2ccb144626c2a4d7554c6d37ec1ce87230f1ded0937ecbbb24c575d3025d","first_computed_at":"2026-07-05T01:17:04.708485Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:17:04.708485Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IyTLB50C978c1jI7zrFACy4gLZx2PcgVZWemqj7u5WUm+cMg8CnLCOctXuB9dwl/446YZk32oytlegHdt+liCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:17:04.708932Z","signed_message":"canonical_sha256_bytes"},"source_id":"2007.03608","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4770c874bd81dad91f3943c5b9f73edde17614dc07b6f2d1e6c489210fc33d8c","sha256:bf40582bfece5db8d5c6f2576d00c54f36889d899e1ec40185f1d8851ffedd36"],"state_sha256":"16c663c05ab68e7c54ad2d96c418c3b0b2c800ee5fe4aa567d8f20925eb048de"}
