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.

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.

Understanding Data Importance in Machine Learning Attacks: Does Valuable Data Pose Greater Harm?
Machine learning has revolutionized numerous domains, playing a crucial role in driving advancements and enabling data-centric processes. The significance of data in training models and shaping their performance cannot be overstated. Recent research has highlighted the heterogeneous impact of individual data samples, particularly the presence of valuable data that significantly contributes to the utility and effectiveness of machine learning models. However, a critical question remains unanswered: are these valuable data samples more vulnerable to machine learning attacks? In this work, we investigate the relationship between data importance and machine learning attacks by analyzing five distinct attack types. Our findings reveal notable insights. For example, we observe that high importance data samples exhibit increased vulnerability in certain attacks, such as membership inference and model stealing. These findings also carry practical implications, inspiring researchers to design more efficient attacks. By analyzing the linkage between membership inference vulnerability and data importance, we demonstrate that sample characteristics can be integrated into membership metrics by introducing sample-specific criteria, therefore enhancing the membership inference performance. These findings emphasize the urgent need for innovative defense mechanisms that strike a balance between maximizing utility and safeguarding valuable data against potential exploitation.

AlphaDog: No-Box Camouflage Attacks via Alpha Channel Oversight
Traditional black-box adversarial attacks on computer vision models face significant limitations, including intensive querying requirements, time-consuming iterative processes, a lack of universality, and low attack success rates (ASR) and confidence levels (CL) due to subtle perturbations. This paper introduces AlphaDog, an Alpha channel attack, the first universally efficient targeted no-box attack, exploiting the often overlooked Alpha channel in RGBA images to create visual disparities between human perception and machine interpretation, efficiently deceiving both. Specifically, AlphaDog maliciously sets the RGB channels to represent the desired object for AI recognition, while crafting the Alpha channel to create a different perception for humans when blended with a standard or default background color of digital media (thumbnail or image viewer apps). Leveraging differences in how AI models and human vision process transparency, AlphaDog outperforms existing adversarial attacks in four key ways: (i) as a no-box attack, it requires zero queries; (ii) it achieves highly efficient generation, taking milliseconds to produce arbitrary attack images; (iii) AlphaDog can be universally applied, compromising most AI models with a single attack image; (iv) it guarantees 100% ASR and CL. The assessment of 6,500 AlphaDog attack examples across 100 state-of-the-art image recognition systems demonstrates AlphaDog's effectiveness, and an IRB-approved experiment involving 20 college-age participants validates AlphaDog's stealthiness. AlphaDog can be applied in data poisoning, evasion attacks, and content moderation. Additionally, a novel pixel-intensity histogram-based detection method is introduced to identify AlphaDog, achieving 100% effectiveness in detecting and protecting computer vision models against AlphaDog. Demos are available on the AlphaDog website
