Data fragmentation using the technique NFA to DFA

Abstract

Today's business environment needs to manage large quantities of data which has enabled a need for a distributed database, as it provides efficient data processing. Data security is a major aspect as the benchmark for confidentiality, integrity and availability of data remains relatively high. In this paper we propose a technique for data security of a file where the file is fragmented, clustered together and store on the server using the non-deterministic finite automata To reconstruct a file the deterministic finite automata technique is used to fetch the file fragments, reorganize and download the whole file.
