{"data":{"id":"a26d40ad-4dc0-469a-8fbb-ed7d89ee2016","title":"Vec2Null: Structured Identity Vectorization and Nulling for One-Shot Face Unlearning","summary":"Vec2Null is a geometry-guided framework for one-shot personal identity unlearning on face-analytics models, where a user supplies a single new face image to request erasure. It first maps the image to a stable identity-level direction through UnoFace, a representation network trained with an asymmetric One-Shot Proxy objective, then applies a projection-based nulling update that steers changes away from retain-sensitive subspaces. The authors report state-of-the-art one-shot face unlearning results across multiple benchmarks, with code promised at github.com/CV-AC/Vec2Null.","solution":"N/A -- no mitigation discussed in source.","labels":["privacy","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11695252","publishedAt":"2026-09-17T13:32:35.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-09-17T13:32:35.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":"peer_reviewed","atlasIds":null}}
