To answer this question: we describe the design, implementation, and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy guarantees for users, a privacy bound tighter than the state-of-the-art differential privacy; (ii) Utility: an interface for data analysts to systematically explore the trade-offs between the output accuracy (with error-estimation) and query execution budget;","authors_text":"Christof Fetzer, Do Le Quoc, Martin Beck, Pramod Bhatotia, Ruichuan Chen, Thorsten Strufe","cross_cats":["cs.CR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2017-01-19T13:16:27Z","title":"Privacy Preserving Stream Analytics: The Marriage of Randomized Response and Approximate Computing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.05403","kind":"arxiv","version":5},"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":"sha256:80f2f751c6c89d8c89ab8ab16062f36b8d4b6ac821b81af32b3cc3f0c60f81ac","target":"record","created_at":"2026-05-18T00:43:08Z","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":"ca3689b8b8cf9abe11695b47216e6fdf34d2ecf16dcb2e7f0e2e6e0196818d47","cross_cats_sorted":["cs.CR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2017-01-19T13:16:27Z","title_canon_sha256":"7c4b46c103ab089c60b2277c6ed480e2ebbf9130418408f380f59d216455a0e9"},"schema_version":"1.0","source":{"id":"1701.05403","kind":"arxiv","version":5}},"canonical_sha256":"0b050c0ebed039b1e77ef8fabbbe48f26170d183de99458498b67f82a4f356b2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0b050c0ebed039b1e77ef8fabbbe48f26170d183de99458498b67f82a4f356b2","first_computed_at":"2026-05-18T00:43:08.808811Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:43:08.808811Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"szbq14M0390g1xE0qMAR/MT1ABmATfGlCsjiOmFwJ2tQgpDaA3E/0ZYrX9r099+JDY5178v4obh1EwiKfqO3BA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:43:08.809458Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.05403","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:80f2f751c6c89d8c89ab8ab16062f36b8d4b6ac821b81af32b3cc3f0c60f81ac","sha256:8e1d2c7c417655a41ef63770fa3ff53d258ef5237316bc10fa2675dcfc05da15"],"state_sha256":"37a19c35ac2e066bb269e29848730afa537120d65558531d265fda26178ee15d"}
