GDPR:当访问个人数据的权利成为威胁时

GDPR: When the Right to Access Personal Data Becomes a Threat

Luca Bufalieri, Massimo La Morgia, Alessandro Mei, Julinda Stefa

摘要:

自GDPR生效一年后,所有网站和数据控制器都更新了存储用户数据的程序。GDPR不仅涵盖了服务提供商应该如何保存数据以及应该保存哪些数据,而且还保证了一种简单的方法来了解收集了哪些数据以及可以自由导出这些数据。在本文中,我们对GDPR第15条提供的数据访问权进行了全面的研究。我们调查了300多名数据控制者,为他们每个人执行访问个人数据的请求。我们发现,几乎每个数据控制器都有一个稍微不同的过程来满足请求,并有几种方法将数据返回给用户,从CSV等结构化文件到监视器的屏幕截图。我们衡量完成访问数据请求所需的时间以及所提供信息的完整性。在这个数据收集阶段之后,我们分析数据控制者建立请求者身份所遵循的身份验证过程。我们发现,50.4%的处理请求的数据控制者,即使他们按照GDPR存储数据,在识别用户的过程中或在发送数据的阶段存在缺陷,使用户面临新的威胁。令人惊讶的是,GDPR在目前的部署中实际上降低了Web服务用户的隐私。

英文摘要:

After one year since the entry into force of the GDPR, all web sites and data controllers have updated their procedures to store users' data. The GDPR does not only cover how and what data should be saved by the service providers, but it also guarantees an easy way to know what data are collected and the freedom to export them. In this paper, we carry out a comprehensive study on the right to access data provided by Article 15 of the GDPR. We examined more than 300 data controllers, performing for each of them a request to access personal data. We found that almost each data controller has a slightly different procedure to fulfill the request and several ways to provide data back to the user, from a structured file like CSV to a screenshot of the monitor. We measure the time needed to complete the access data request and the completeness of the information provided. After this phase of data gathering, we analyze the authentication process followed by the data controllers to establish the identity of the requester. We find that 50.4\% of the data controllers that handled the request, even if they store the data in compliance with the GDPR, have flaws in the procedure of identifying the users or in the phase of sending the data, exposing the users to new threats. With the undesired and surprising result that the GDPR, in its present deployment, has actually decreased the privacy of the users of web services.
