In the enrollment stage, an individual provides a biometric signal that is mapped into a secret key and a helper message, the former being prepared to become available to the system at a later time (for authentication), and the latter is stored in a public database. When an authorized user requests authentication, claiming his/her identity as one of the subscribers, s/he has to provide a biometric signal again, and then the system, which retrieves also the helper messag","authors_text":"Neri Merhav","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-07-28T05:22:50Z","title":"Ensemble Performance of Biometric Authentication Systems Based on Secret Key Generation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.09108","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":"sha256:9b22000477eaf2c4e9f825959b3135e1424f7bbf969dba99238680bad93304f0","target":"record","created_at":"2026-05-18T00:39:17Z","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":"ac9e83df114da4c4307d0e720a7003d2a2cf4bd0305dc0d781b2a02c9f3733a3","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-07-28T05:22:50Z","title_canon_sha256":"1ca2267926bdf6ebd111f82a831e30e9eb3cafb46d1d1d1600c35e07ca1bbb70"},"schema_version":"1.0","source":{"id":"1707.09108","kind":"arxiv","version":1}},"canonical_sha256":"e02338eff06c9d01682bc2f17969d548674c90b8fe82949e51f5237024fc4bf8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e02338eff06c9d01682bc2f17969d548674c90b8fe82949e51f5237024fc4bf8","first_computed_at":"2026-05-18T00:39:17.075280Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:39:17.075280Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3jApNQoOzz3hlcWsJ4vvMaj8HP48uPRhmVI2W281iLOjLHzJPR8Mg7aM7ZavfeXQNebRf0WKC2jhpx/15Ca2DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:39:17.075938Z","signed_message":"canonical_sha256_bytes"},"source_id":"1707.09108","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9b22000477eaf2c4e9f825959b3135e1424f7bbf969dba99238680bad93304f0","sha256:71aa431fc804eb02cc1b6fa78f9258ee2d921c75eefc8d7aa04de6f60c6f1814"],"state_sha256":"712952bc488ec87429e5b62b9f5a4cfb77827404995f32b257fd0ccda344b3aa"}
