Privacy-protection solid-state storage (PP-SSS) system: Automatic lifetime management of internet-data´s right to be forgotten

Recently, a new right, the “Right to be forgotten”, has been defined for privacy protection. One approach to protect personal information is to control the data´s lifetime or expiration. Here, a privacy-protection solid-state storage (PP-SSS) system is proposed, in which personal data is automatically invalidated within the hardware itself. In the proposed data-lifetime management (DLM) scheme, the same physical memory cells can be programmed to have different data lifetimes.
