Abstract:
Deep learning has achieved many big innovations in all industries and significantly impacted our daily lives. However, deep learning can also result in severe security and privacy risks to users and service providers. In this talk, I will present our recent works on trustworthy deep learning systems. First, we design and implement the first black-box attack framework that generates universal 3-dimensional (U3D) perturbations to subvert a wide variety of video understanding deep learning systems. The new U3D attack is easy-to-launch, universal, transferable, and human-imperceptible. It can also bypass the state-of-the-art defense methods. Such novel attack motivates the video recognition systems to build and integrate more robust deep learning models. Second, we design and implement the first cryptographic system (Crypto3D) for private and efficient deep learning based on spatial-temporal features extracted from videos. Crypto3D significantly outperforms existing systems (extensible to inferences on 3D features) on execution time: 186.89x vs. CryptoDL (3D), 63.75x vs. HEANN (3D), 61.52x vs. MP-SPDZ (3D), 45x vs. E2DM (3D), 3.74x vs. Intel SGX (3D), and 3x vs. Gazelle (3D); and on accuracy: 82.3% vs. below 56% for all of them.
