We focus on the important machine learning task of classification. This leads us to propose a provably secure four-round protocol that computes the value of the data to be traded without revealing the data to the potential acquirer. The theoretical results demonstrate a number of important properties of the proposed protocol. In particular, we prove the security of the proposed protocol in the honest-but-curious adversary model.","authors_text":"Frank Torres, Hoda Eldardiry, Ryan Rossi, Shantanu Rane, Vanishree Rao, Yunhui Long","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2019-01-03T18:01:33Z","title":"Secure Two-Party Feature Selection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1901.00832","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:a8be471095aa8fb39152750b12079dcb25974ecc4f49621ebd421f5aa2810040","target":"record","created_at":"2026-05-17T23:57:01Z","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":"264a714d39f69c29fc5f79782d75a3595942087a2ab2ea78260dfbd927dc4b26","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2019-01-03T18:01:33Z","title_canon_sha256":"6ad4c147b937de4b55b530b9f2b1f21baf204329522312aaf74e8a9c9262f50a"},"schema_version":"1.0","source":{"id":"1901.00832","kind":"arxiv","version":1}},"canonical_sha256":"603ae36ff400d28f8eb55d78021db7c5d1748c26aa78eb9a99835f66580ffbc8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"603ae36ff400d28f8eb55d78021db7c5d1748c26aa78eb9a99835f66580ffbc8","first_computed_at":"2026-05-17T23:57:01.128907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:01.128907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YcS86LC7z5KHAOJBjrJZmbOTiD7JV8RndhCMRCrEHfeAdAtAXo9vKEg2UY+9qsWHWj6dPexrUMoFH7O3UZizAQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:01.129672Z","signed_message":"canonical_sha256_bytes"},"source_id":"1901.00832","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a8be471095aa8fb39152750b12079dcb25974ecc4f49621ebd421f5aa2810040","sha256:69330c564d09c03d9a28da1eb6644c336a876a5f6542917c94d048d660b7dce0"],"state_sha256":"db89e7b0db3bf823dafcc249f996699295794b46af4c3cdc2e560d4cd9a5ff32"}
