{"data":{"id":"520453dd-b7d5-4990-b54d-1ee546b820be","title":"SeVoAuth: Secure Voiceprint Authentication With Hash-Based Feature Transformation","summary":"SeVoAuth is a cloud-based voiceprint authentication system (a security method that recognizes users by their unique voice characteristics) designed to protect user privacy while defending against replay attacks (replaying a recorded voice), spoofing (faking a voice), and adversarial attacks (manipulating input to fool the system). The system stores a synthesized version of a user's voice in the cloud and uses hash functions (mathematical functions that transform data into fixed-size codes) to continuously change the verification targets during each login, making it difficult for attackers to reuse old voice recordings or tricks.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11425839","publishedAt":"2026-03-09T13:17:52.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_evasion"],"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":"2026-03-09T13:17:52.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality","integrity"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.75,"researchCategory":"peer_reviewed","atlasIds":null}}
