Probe-Me-Not: Protecting Pre-Trained Encoders From Malicious Probing
Adapting pre-trained deep learning models to customized tasks has become a popular choice for developers to cope with limited computational resources and data volume. More specifically, probing--training a classifier on a pre-trained encoder--has been widely adopted in transfer learning, which helps to prevent overfitting and catastrophic forgetting. However, such generalizability of pre-trained encoders raises concerns about the potential misuse of probing for harmful applications, such as discriminatory speculation and warfare applications. In this work, we introduce EncoderLock, a novel applicability authorization method designed to protect pre-trained encoders from malicious probing, i.e., yielding poor performance on specified prohibited domains while maintaining their utility in authorized ones. Achieving this balance is challenging because of the opposite optimization objectives and the variety of downstream heads that adversaries can utilize adaptively. To address these challenges, EncoderLock employs two techniques: domain-aware weight selection and updating to restrict applications on prohibited domains/tasks, and self-challenging training scheme that iteratively strengthens resistance against any potential downstream classifiers that adversaries may apply. Moreover, recognizing the potential lack of data from prohibited domains in practical scenarios, we introduce three EncoderLock variants with different levels of data accessibility: supervised (prohibited domain data with labels), unsupervised (prohibited domain data without labels), and zero-shot (no data or labels available). Extensive experiments across fifteen domains and three model architectures demonstrate EncoderLock's effectiveness over baseline methods using non-transferable learning. Additionally, we verify EncoderLock's effectiveness and practicality with a real-world pre-trained Vision Transformer (ViT) encoder from Facebook. These results underscore the valuable contributions EncoderLock brings to the development of responsible AI.

PAPER
A New PPML Paradigm For Quantized Models
Model quantization has become a common practice in machine learning (ML) to improve efficiency and reduce computational/communicational overhead. However, adopting quantization in privacy-preserving machine learning (PPML) remains challenging due to the complex internal structure of quantized operators, which leads to inefficient protocols under the existing PPML frameworks. In this work, we propose a new PPML paradigm that is tailor-made for and can benefit from quantized models. Our main observation is that look-up tables can ignore the complex internal constructs of any functions which can be used to simplify the quantized operator evaluation. We view the model inference process as a sequence of quantized operators, and each operator is implemented by a look-up table. We then develop an efficient private look-up table evaluation protocol, and its online communication cost is only log n, where $n$ is the size of the look-up table. On a single CPU core, our protocol can evaluate 2^{26} tables with 8-bit input and 8-bit output per second. The resulting PPML framework for quantized models offers extremely fast online performance. The experimental results demonstrate that our quantization strategy achieves substantial speedups over SOTA PPML solutions, improving the online performance by 40sim 60 times w.r.t. convolutional neural network (CNN) models, such as AlexNet, VGG16, and ResNet18, and by 10sim 25 times w.r.t. large language models (LLMs), such as GPT-2, GPT-Neo, and Llama2.

PAPER
DLBox: New Model Training Framework For Protecting Training Data
Sharing training data for deep learning raises critical concerns about data leakage, as third-party AI developers take full control over the data once it is handed over to them. The problem becomes even worse if the model trained using the data should be returned to the third-party AI developers - e.g., healthcare startup training its own model using the medical data rented from a hospital. In this case, the malicious developers can easily leak the training data through the model as he can construct an arbitrary data flow between them - e.g., directly encoding raw training data into the model, or stealthily biasing the model to resemble the training data. However, current model training frameworks do not provide any protection to prevent such training data leakage, allowing the untrusted AI developers to leak the data without any restriction. This paper proposes DLBox, a new model training framework to minimize the attack vectors raised by untrusted AI developers. Since it is infeasible to completely prevent data leakage through the model, the goal of DLBox is to allow only a benign model training such that the data leakage through invalid paths are minimized. The key insight of DLBox is that the model training is a statistical process of learning common patterns from a dataset. Based on it, DLBox defines DGM-Rules, which determine whether a model training code from a developer is benign or not. Then, DLBox leverages confidential computing to redesign current model training framework, enforcing only DGM-Rules-based training. Therefore, untrusted AI developers are strictly limited to obtain only the benignly trained model, prohibited from intentionally leaking the data. We implemented the prototype of DLBox on PyTorch with AMD SEV-SNP, and demonstrated that DLBox eliminates large attack vectors by preventing previous attacks (e.g., data encoding, and gradient inversion) while imposing minimal performance overhead.
