ENCRYPTED DATA DEDUPLICATION IN CLOUD STORAGE

摘要

There is provided a method of storing data in a cloud storage system, the method including: generating a file identifier for a data file desired to be stored in the cloud storage system; encrypting the file identifier of the data file using a homomorphic encryption technique to produce an encrypted file identifier of the data file; and transmitting the encrypted file identifier to the cloud storage system for performing data deduplication in relation to the cloud storage system with respect to the data file. There is also provided an associated client device and cloud storage system.
