핵심 개념
ModelObfuscator proposes a novel technique to obfuscate on-device ML models, enhancing security by hiding key information and preventing attacks.
초록
Edge devices and mobile apps leverage DL capabilities, but on-device models are vulnerable to attacks.
Model obfuscation hides key model information to protect against white-box attacks.
Techniques include renaming, parameter encapsulation, neural structure obfuscation, shortcut injection, and extra layer injection.
ModelObfuscator tool improves model security without increasing latency.
Obfuscated models show no impact on prediction accuracy but increase memory overhead.
Structure obfuscation confuses attackers by changing the model's architecture.
Obfuscation strategies have negligible time overhead but increase TFLite library size.
통계
최근 연구에 따르면 공격자들은 모델의 내부 정보를 추출할 수 있음.
ModelObfuscator는 모델 파일과 구조를 효과적으로 난독화함.
난독화된 모델은 원본 모델의 예측 결과에 영향을 미치지 않음.
