Online services are used for all kinds of activities, like news, entertainment, publishing content or connecting with others. But information technology enables new threats to privacy by means of global mass surveillance, vast databases and fast distribution networks. Current news are full of misuses and data leakages. In most cases, users are powerless in such situations and develop an attitude of neglect for their online behaviour. On the other hand, the GDPR (General Data Protection Regulation) gives users the right to request a copy of all their personal data stored by a particular service, but the received data is hard to understand or analyze by the common internet user. This paper presents TransparencyVis - a web-based interface to support the visual and interactive exploration of data exports from different online services. With this approach, we aim at increasing the awareness of personal data stored by such online services and the effects of online behaviour. This design study provides an online accessible prototype and a best practice to unify data exports from different sources.

翻译：在线服务用于各种活动,如新闻、娱乐、出版内容或与他人连接等。但信息技术通过全球大规模监控、庞大的数据库和快速传播网络,对隐私造成新的威胁。当前新闻充斥着滥用和数据泄漏。在大多数情况下,用户在这种情况下无能为力,对其在线行为形成一种忽视态度。另一方面,GNSR(一般数据保护条例)赋予用户要求由特定服务储存的所有个人数据副本的权利,但普通互联网用户很难理解或分析收到的数据。本文介绍透明Vision(透明Vision)——一个基于网络的界面,用以支持对不同在线服务的数据出口进行视觉和互动探索。我们这样做的目的是提高对这类在线服务所储存的个人数据的认识以及在线行为的影响。这一设计研究提供了一种在线可访问的原型和统一不同来源数据出口的最佳做法。
