Facebook在欧洲使用敏感数据做广告

Facebook Use of Sensitive Data for Advertising in Europe

José González Cabañas, Ángel Cuevas, Rubén Cuevas

摘要:

即将出台的《欧洲通用数据保护条例》(GDPR)禁止处理和利用某些类别的个人数据(健康、政治取向、性偏好、宗教信仰、民族血统等)。这是由于恶意使用此类信息可能导致明显的隐私风险。这些类别被称为敏感个人数据。Facebook最近在西班牙被罚款120万欧元,原因是出于广告目的收集、存储和处理敏感个人数据。本文量化了欧盟(EU)中被贴上与敏感个人数据相关的兴趣标签的Facebook用户的比例。我们的研究结果显示,Facebook将73%的欧盟用户标记为敏感兴趣。这相当于欧盟总人口的40%。我们还估计,恶意第三方可能会以每个用户0.015欧元的低成本揭露被分配敏感兴趣的Facebook用户的身份。最后,我们提出并实现了一个Web浏览器扩展,以通知Facebook用户的敏感利益Facebook已经分配给他们。

英文摘要:

The upcoming European General Data Protection Regulation (GDPR) prohibits the processing and exploitation of some categories of personal data (health, political orientation, sexual preferences, religious beliefs, ethnic origin, etc.) due to the obvious privacy risks that may be derived from a malicious use of such type of information. These categories are referred to as sensitive personal data. Facebook has been recently fined EUR 1.2M in Spain for collecting, storing and processing sensitive personal data for advertising purposes. This paper quantifies the portion of Facebook users in the European Union (EU) who are labeled with interests linked to sensitive personal data. The results of our study reveal that Facebook labels 73% EU users with sensitive interests. This corresponds to 40% of the overall EU population. We also estimate that a malicious third-party could unveil the identity of Facebook users that have been assigned a sensitive interest at a cost as low as EUR 0.015 per user. Finally, we propose and implement a web browser extension to inform Facebook users of the sensitive interests Facebook has assigned them.
