Abstract

Deep neural networks (DNNs) for biometrics represent the intellectual property of model owners due to the extensive biometric data and significant computing resources required for training them. However, existing technologies for protecting the intellectual property of DNNs are primarily tailored for general tasks and often fail to account for the unique characteristics of DNNs for biometrics. Consequently, these technologies have limitations as they may increase data costs. This is because they typically require additional data samples to construct pairs that can be used for verifying intellectual property. Given the heightened privacy concerns and the challenging nature of acquiring authorized biometric data, addressing the issue of increased data costs is paramount in biometric model intellectual property protection technology. To address this challenge, we introduce MGIP (Multi-Generator Intellectual Property protection), a novel data-free fingerprinting framework specifically designed for biometric classifiers. Our key technology innovations include: (1) a collaborative multi-generator architecture that creates a variety of fingerprints without external data, (2) an adaptive threshold strategy that dynamically adjusts verification criteria, and (3) a robust fingerprint selection that ensures reliable ownership verification. In our empirical evaluation, we conduct an ablation study using three state-of-the-art technologies and six datasets, including three general datasets and three biometric datasets. Our comparative analysis demonstrates that MGIP consistently outperforms three state-of-the-art technologies in accurately identifying pirated models.
用于生物特征分类器的无数据指纹技术
生物识别的深度神经网络(dnn)代表了模型所有者的知识产权,因为广泛的生物识别数据和训练它们所需的大量计算资源。然而,现有的保护深度神经网络知识产权的技术主要是为一般任务量身定制的,往往不能考虑到生物识别中深度神经网络的独特特征。因此,这些技术具有局限性,因为它们可能增加数据成本。这是因为它们通常需要额外的数据样本来构建可用于验证知识产权的对。鉴于高度的隐私问题和获取授权生物特征数据的挑战性,解决数据成本增加的问题在生物特征模型知识产权保护技术中至关重要。为了应对这一挑战,我们引入了MGIP(多生成器知识产权保护),这是一种专门为生物识别分类器设计的新型无数据指纹框架。我们的关键技术创新包括:(1)无需外部数据即可创建各种指纹的协作多生成器架构,(2)动态调整验证标准的自适应阈值策略,以及(3)确保可靠所有权验证的稳健指纹选择。在我们的实证评估中,我们使用三种最先进的技术和六个数据集进行消融研究,包括三个通用数据集和三个生物特征数据集。我们的比较分析表明,MGIP在准确识别盗版模型方面始终优于三种最先进的技术。
