{"data":{"id":"1f9cbf07-def9-4c7c-afc4-82d6f418a40d","title":"Analysis of Collaborative Data Privacy Leakage: A Macro-Level Perspective","summary":"This research paper examines macro-level collaborative leakage, which occurs when individually harmless data pieces reveal sensitive information when combined together. The authors conducted mathematical analyses to understand why this happens and found that the problem stems from how risk data (data that don't directly expose private information) correlate with sensitive information. While Gaussian distribution (a common bell-curve statistical pattern) can help prevent this type of leakage, the paper concludes that this protection is limited and more comprehensive security mechanisms are needed.","solution":"N/A -- no mitigation discussed in source.","labels":["privacy","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11483233","publishedAt":"2026-04-17T13:18:38.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["data_extraction"],"issueType":"research","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-04-17T13:18:38.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality"],"aiComponentTargeted":"training_data","llmSpecific":false,"classifierConfidence":0.75,"researchCategory":"peer_reviewed","atlasIds":null}}
