Specifically, in the Helper problem, an encoder communicates with a legitimate receiver through noise-free rate-limited public and private links; and an external passive eavesdropper intercepts every information that is sent on the public link. We study two classes of this model: i) when a pair of arbitrarily correlated discrete memoryless sources is to be encoded such that one component has to be recovered lossily at the legitimate receiver while the ","authors_text":"Abdellatif Zaidi, Meryem Benammar","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-01-13T10:46:34Z","title":"Secure Lossy Source Coding for Some Classes of Helper and Gray-Wyner Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.03621","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:e7f30fa2d36134e621f073a525a9d8b1fe920a02e6c9cfe6a6e9686eb875858c","target":"record","created_at":"2026-05-18T00:52:54Z","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":"a0b081f606e058f086b00ad2d253b2015d2c3c7e1466fb71c6c7e67148f675b8","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-01-13T10:46:34Z","title_canon_sha256":"fcb4414bdf9e8f7880f3ffb10e96e399abd91f67ef1fa8e63a5c89345eabe3a3"},"schema_version":"1.0","source":{"id":"1701.03621","kind":"arxiv","version":1}},"canonical_sha256":"850649418b5d86f18696def5670b3c5cb473e1728b725e9a46d5e9ca9a3448f7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"850649418b5d86f18696def5670b3c5cb473e1728b725e9a46d5e9ca9a3448f7","first_computed_at":"2026-05-18T00:52:54.341227Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:52:54.341227Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1q3FtvQKuy+ucswQ58NlGjd168s7/DZQcLLRw58g9mCzD/2rtJnERWRv4+eg6Po/CuKceKzPNp5xNx4aWCIlBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:52:54.341920Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.03621","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e7f30fa2d36134e621f073a525a9d8b1fe920a02e6c9cfe6a6e9686eb875858c","sha256:413c51614f745ce5e5463809022a2ec67b5c8a6670e960ff170368197f078065"],"state_sha256":"e337e4ccf0166a795ca89010c482da2e3dd62e491688110e79ab166b6187f68a"}
