摘要:

机器学习即服务(MLaaS),如Microsoft Azure、Amazon AWS,为受限于缺乏数据和计算能力的小型企业和个人提供了有效的DNN模型来完成机器学习任务。然而,这里有一个问题,即用户隐私暴露给MLaaS服务器,因为用户需要将其敏感数据上传到MLaaS服务器。为了保护他们的隐私,用户可以在上传之前加密他们的数据。这使得DNN模型很难运行,因为它不是为在密文域中运行而设计的。在本文中,使用Paillier同态密码系统,我们提出了一个新的隐私保护深度神经网络模型,我们称之为2 P-DNN。该模型可以完成密文域的机器学习任务。通过使用2 P-DNN,MLaaS能够为用户提供隐私保护机器学习服务。我们基于LeNet-5构建了我们的2 P-DNN模型,并使用加密的MNIST数据集对其进行了测试。分类准确率超过97%,接近MNIST数据集运行的LeNet-5的准确率,高于其他现有的隐私保护机器学习模型

英文摘要:

Machine Learning as a Service (MLaaS), such as Microsoft Azure, Amazon AWS, offers an effective DNN model to complete the machine learning task for small businesses and individuals who are restricted to the lacking data and computing power. However, here comes an issue that user privacy is ex-posed to the MLaaS server, since users need to upload their sensitive data to the MLaaS server. In order to preserve their privacy, users can encrypt their data before uploading it. This makes it difficult to run the DNN model because it is not designed for running in ciphertext domain. In this paper, using the Paillier homomorphic cryptosystem we present a new Privacy-Preserving Deep Neural Network model that we called 2P-DNN. This model can fulfill the machine leaning task in ciphertext domain. By using 2P-DNN, MLaaS is able to provide a Privacy-Preserving machine learning ser-vice for users. We build our 2P-DNN model based on LeNet-5, and test it with the encrypted MNIST dataset. The classification accuracy is more than 97%, which is close to the accuracy of LeNet-5 running with the MNIST dataset and higher than that of other existing Privacy-Preserving machine learning models
