File Construction and Reconstruction in Cloud Computing

Now a days cloud computing is a very popular method. Cloud storage means the storage of data online in the cloud. Cloud computing is a model of cloud storage in which data is put in storage on remote servers which is retrieved from the internet. Cloud storage services are very popular. In this survey, two algorithm are studied Ramp Secret Share Algorithm and Chunking Algorithm. Ramp Secret Share Scheme follow the Sharmir polynomial function. In secret share scheme there is distribution to no of server and reconstruction again. Chunking algorithm splits the big data into small part or chunks. Chunking algorithm are very important to Deduplication technique. Chunking algorithm is used to increase efficiency of data deduplication ratio and data deduplication throughput.
