治愈隐私:功能加密和隐私保护分析

Heal the Privacy: Functional Encryption and Privacy-Preserving Analytics

Alexandros Bakas, Antonis Michalas

摘要:

安全的云存储是一个至关重要的问题,企业和最终用户在将数据移动到可能不受信任的云之前都应该考虑。将数据迁移到云会引发多个隐私问题,因为它们完全由云提供商控制。因此,不受信任的云提供商可能会侵犯用户的隐私并获得对敏感信息的访问。当云提供商需要存储统计数据库并定期发布分析时,这个问题变得更加突出。在这项工作中,我们首先提出了一个详细的例子,表明使用密码学是不够的,以确保个人的隐私。然后,我们设计了一个基于函数加密和差分隐私的混合协议,该协议允许以隐私保护的方式进行统计计算。

英文摘要:

Secure cloud storage is an issue of paramount importance that both businesses and end-users should take into consideration before moving their data to, potentially, untrusted clouds. Migrating data to the cloud raises multiple privacy issues, as they are completely controlled by a cloud provider. Hence, an untrusted cloud provider can potentially breach users; privacy and gain access to sensitive information. The problem becomes even more pronounced when the could provider is required to store a statistical database and periodically publish analytics. In this work, we first present a detailed example showing that the use of cryptography is not enough to ensure the privacy of individuals. Then, we design a hybrid protocol based on Functional Encryption and Differential Privacy that allows the computations of statistics in a privacy-preserving way.
