Sedas: A Self Destructive Active Storage Framework for Data Privacy
R C Dharmik Hemlata · International Journal of Scientific Engineering and Research · 2014
Personal data that we store in the Cloud may contain account numbers, passwords, notes, and other important information that could be used and misused by a miscreant, a competitor, or a court of law.These data are cached and copied by Cloud Service Providers, often without users' authorization and control.Self-destructing data mainly aims at protecting the user data's privacy.All the data and their copies become destructed or unreadable after a user-specified time, without any information to user.In addition, the decryption key is destructed after the user-specified time.In this paper, we present a system that meets this challenge through a novel integration of cryptographic techniques with active storage techniques.We implemented a proof-of-concept self destructive prototype.Through functionality and security properties evaluations of this prototype, the results demonstrate that the system is practical to use and meets all the privacy-preserving goals described.Compared to the system without self-destructing data mechanism, throughput for uploading and downloading with the proposed system acceptably decreases, while latency for upload/download operations with selfdestructing data mechanism increases.
