Data protection by means of fragmentation in various different distributed storage systems - a survey
It provides a systematic review for researchers and practitioners in data security, but is incremental as it organizes existing solutions without introducing new methods.
This paper surveys distributed storage systems that use data fragmentation and dispersal for data protection, categorizing them into bitwise and structurewise approaches based on data structure and environment.
This paper analyzes various distributed storage systems that use data fragmentation and dispersal as a way of protection.Existing solutions have been organized into two categories: bitwise and structurewise. Systems from the bitwise category are operating on unstructured data and in a uniform environment. Those having structured input data with predefined confidentiality level and disposing of a heterogeneous environment in terms of machine trustworthiness were classified as structurewise. Furthermore, we outline high-level requirements and desirable architecture traits of an eficient data fragmentation system, which will address performance (including latency), availability, resilience and scalability.
