Secure Deduplication For Cloud Storage Using Memory Mapping Technique For Improving Performance And Security

Data deduplication is a crucial technique for packing data and reducing duplication when transferring data. It widely used in the cloud to restrict usage of capacity memory aids transmission sparing. Before redistributing data, an encryption mechanism ensure integrity sensitive during process. The SHA algorithm being save text format. To generate security bits, padding appended text. In de-duplication, it calculates hash, i.e. hexadecimal number, string, integer Hash-based de-duplication implementation whole file hashing entire file. Text data’s hash values are considered as feature properties. contrast traditional solutions, clients that transfer certify inside virtualization, both limiting primary size blockage important bottlenecks. Memory identifies pages with same content merges them into single file, usage, parceling, improving execution. storage, MPT so copies different owners. If any users try replicate will be mapped related archive implying can’t stored away. security, techniques encrypt throughout procedures prior outsourcing
