Ankit Shrivastava, Abhigyan Tiwary · 2018
Big data deduplication is one of the most challenging task in the cloud world. There are two major issue generated in the cyber world first is the data preservation on cloud and second one is big duplication. In this research proposed a new model to solve both problems. In this paper proposed modified hash value concept, with the help of this avoid big data problem and for secure data protection use HECC algorithm for data encryption and decryption. SHA2 algorithm consume less time as compare to SHA-1 for hash value generation and HECC shows better encryption as compare to other methods. In this research also analysed the different methods such AES, DSA and ECC for data encryption on the basic of time complexity. The proposed system shows better result as compare to other previous data duplication methods for the basis of time and security.
