智能物联网系统能够整合来自周围环境的知识，并且是下一代互联网的关键组成部分。这类系统通常通过众多设备从各个维度收集数据，且收集到的数据通常是可关联的。这意味着它们可以被组合以得出大量有价值的知识。然而，收集到的数据也可能被恶意的第三方获取，从而泄露敏感信息。在本文中，我们研究智能物联网系统中可关联数据的隐私问题，这在以往的研究中尚未得到充分探讨。我们首先讨论智能物联网系统中可用的数据源及其关联性。然后我们介绍一些可能访问和利用可关联数据的第三方。针对智能物联网系统中的个人和群体，全面阐述了潜在的威胁。最后，我们强调了智能物联网系统中可关联数据隐私保护的一些挑战和未解决的问题。
Smart IoT systems can integrate knowledge from the surrounding environment, and they are critical components of the next-generation Internet. Such systems usually collect data from various dimensions via numerous devices, and the collected data are usually linkable. This means that they can be combined to derive abundant valuable knowledge. However, the collected data may also be accessed by malicious third parties to reveal sensitive information. In this article, we investigate the privacy issues of linkable data in smart IoT systems, which have not been thoroughly studied in previous works. We first discuss the available data sources in smart IoT systems and their linkage. Then we introduce some third parties who may access and utilize the linkable data. The potential threats are comprehensively elaborated for both individuals and crowds in smart IoT systems. Finally, we highlight some challenges and open problems for privacy preservation of linkable data in smart IoT systems.
