This article proposes a General Data Protection Regulation (GDPR)-compliant Internet of Things (IoT) Recommender (IoTRec) system, developed in the framework of H2020 EU-KR WISE-IoT (Worldwide Interoperability for Semantic IoT) project, which provides the recommendations of parking spots and routes while protecting users’ privacy. It provides recommendations by exploiting the IoT technology (parking and traffic sensors). The IoTRec provides four-fold functions. First, it helps the user to find a free parking spot based on different metrics (such as the nearest or nearest trusted parking spot). Second, it recommends a route (the least crowded or the shortest route) leading to the recommended parking spot from the user’s current location. Third, it provides the real-time provision of expected availability of parking areas (comprised of parking spots organized into groups) in a user-friendly manner. Finally, it provides a GDPR-compliant implementation for operating in a privacy-aware environment. The IoTRec is integrated into the smart parking use case of the WISE-IoT project and is evaluated by the citizens of Santander, Spain through a prototype, but it can be applied to any IoT-enabled locality. The evaluation results show the citizen’s satisfaction with the quality, functionalities, ease of use and reliability of the recommendations/services offered by the IoTRec.

IoTRec：智能停车系统的物联网推荐器

本文提出了一个符合通用数据保护条例 (GDPR) 的物联网 (IoT) 推荐器 (IoTRec) 系统，该系统是在 H2020 EU-KR WISE-IoT (Worldwide Interoperability for Semantic IoT) 项目的框架下开发的，它提供了建议停车位和路线，同时保护用户隐私。它通过利用物联网技术（停车和交通传感器）提供建议。IoTRec 提供四重功能。首先，它帮助用户根据不同的指标（例如最近或最近的可信停车位）找到一个免费停车位。其次，它推荐一条从用户当前位置到推荐停车位的路线（最不拥挤或最短的路线）。第三，它以用户友好的方式实时提供停车位的预期可用性（由分组的停车位组成）。最后，它提供了一个符合 GDPR 的实现，用于在隐私感知环境中运行。IoTRec 已集成到 WISE-IoT 项目的智能停车用例中，并由西班牙桑坦德市民通过原型进行评估，但它可以应用于任何支持物联网的地区。评估结果表明公民对 IoTRec 提供的建议/服务的质量、功能、易用性和可靠性感到满意。IoTRec 已集成到 WISE-IoT 项目的智能停车用例中，并由西班牙桑坦德市民通过原型进行评估，但它可以应用于任何支持物联网的地区。评估结果表明公民对 IoTRec 提供的建议/服务的质量、功能、易用性和可靠性感到满意。IoTRec 已集成到 WISE-IoT 项目的智能停车用例中，并由西班牙桑坦德市民通过原型进行评估，但它可以应用于任何支持物联网的地区。评估结果表明公民对 IoTRec 提供的建议/服务的质量、功能、易用性和可靠性感到满意。
