数据保留法制定了旨在保护隐私的规则。这些定义了保留期限（数据必须保留多长时间）和清除期限（数据必须在存储中销毁时）。为了遵守法律并尽可能减少责任，公司应该销毁必须清除或不再需要的数据。然而，数据库备份通常不能被编辑以清除“过期”数据，并且擦除整个备份是不切实际的。为了保持合规性，数据管理者需要一种机制来支持有针对性地销毁备份中的数据。在本文中，我们提出了一个加密擦除框架，可以从所有数据库备份中清除数据。我们的方法可以透明地集成到现有的数据库备份过程中。我们演示了如何通过视图定义不同的清除策略，并在不违反数据库约束的情况下通过触发器强制执行。
Data retention laws establish rules intended to protect privacy. These define both retention durations (how long data must be kept) and purging deadlines (when the data must be destroyed in storage). To comply with the laws and to minimize liability, companies should destroy data that must be purged or is no longer needed. However, database backups generally cannot be edited to purge “expired” data and erasing the entire backup is impractical. To maintain compliance, data curators need a mechanism to support targeted destruction of data in backups.In this paper, we present a cryptographic erasure framework that can purge data from all database backups. Our approach can be transparently integrated into existing database backup processes. We demonstrate how different purge policies can be defined through views and enforced by triggers without violating database constraints.
