摘要:

为了从边缘设备收集的大量数据中提取知识,由于通信带宽限制以及最终用户的隐私和安全问题,需要数据上传的传统基于云的方法可能不可行。为了解决这些问题,本文提出了一种新的隐私保护边缘计算框架的图像分类。具体来说,自动编码器将在每个边缘设备上单独进行无监督训练,然后将获得的潜在向量传输到边缘服务器用于训练分类器。该框架将减少通信开销并保护最终用户的数据。与联邦学习相比,该框架中分类器的训练不受边缘设备的约束,自动编码器可以在每个边缘设备上独立训练,无需任何服务器参与。此外,通过传输潜在向量来保护最终用户数据的隐私,而无需额外的加密成本。实验结果提供了关于图像分类性能与各种设计参数(例如自动编码器的数据压缩比和模型复杂度)的关系的见解。

英文摘要:

In order to extract knowledge from the large data collected by edge devices, traditional cloud based approach that requires data upload may not be feasible due to communication bandwidth limitation as well as privacy and security concerns of end users. To address these challenges, a novel privacy preserving edge computing framework is proposed in this paper for image classification. Specifically, autoencoder will be trained unsupervised at each edge device individually, then the obtained latent vectors will be transmitted to the edge server for the training of a classifier. This framework would reduce the communications overhead and protect the data of the end users. Comparing to federated learning, the training of the classifier in the proposed framework does not subject to the constraints of the edge devices, and the autoencoder can be trained independently at each edge device without any server involvement. Furthermore, the privacy of the end users' data is protected by transmitting latent vectors without additional cost of encryption. Experimental results provide insights on the image classification performance vs. various design parameters such as the data compression ratio of the autoencoder and the model complexity.
