实用程序感知的隐私保护数据发布

Utility-aware Privacy-preserving Data Releasing

University of South Florida(南佛罗里达大学)

Di Zhuang, J. Morris Chang

摘要:

在大数据时代,越来越多的基于云的数据驱动应用程序被开发出来,这些应用程序利用个人数据来提供某些有价值的服务(实用程序)。另一方面,由于可以利用同一组个人数据来推断个人的某些敏感信息,因此它创建了窥探个人隐私的新渠道。因此,开发使数据所有者能够发布私有化数据的技术非常重要,这些数据仍然可以用于某些特定的预期目的。然而,现有的数据发布方法要么是强调隐私(不考虑效用),要么是效用驱动(不保证隐私)。在这项工作中,我们提出了一个两步扰动为基础的效用感知的隐私保护数据发布框架。首先,从公共领域数据(背景知识)中学习某些预定义的隐私和效用问题。之后,我们的方法利用学习到的知识来精确地将数据所有者的数据扰动成私有化数据,这些数据可以成功地用于某些预期目的(学习成功),而不会危及某些预定义的隐私(训练失败)。在人类活动识别、人口普查收入和银行营销数据集上进行了广泛的实验,以证明我们的框架的有效性和实用性。

英文摘要:

In the big data era, more and more cloud-based data-driven applications are developed that leverage individual data to provide certain valuable services (the utilities). On the other hand, since the same set of individual data could be utilized to infer the individual's certain sensitive information, it creates new channels to snoop the individual's privacy. Hence it is of great importance to develop techniques that enable the data owners to release privatized data, that can still be utilized for certain premised intended purpose. Existing data releasing approaches, however, are either privacy-emphasized (no consideration on utility) or utility-driven (no guarantees on privacy). In this work, we propose a two-step perturbation-based utility-aware privacy-preserving data releasing framework. First, certain predefined privacy and utility problems are learned from the public domain data (background knowledge). Later, our approach leverages the learned knowledge to precisely perturb the data owners' data into privatized data that can be successfully utilized for certain intended purpose (learning to succeed), without jeopardizing certain predefined privacy (training to fail). Extensive experiments have been conducted on Human Activity Recognition, Census Income and Bank Marketing datasets to demonstrate the effectiveness and practicality of our framework.
