A New Scheme for Storage and Retrieval of Shared Text Files

Hussein Shirvani, Hamed Vahdat-Nejad

Abstract


Recently, there has been an increasing need for storage spaces in the cloud centers. Efficient techniques for storing files can slow down this trend. In this paper, we investigate the problem of storing replicated text files that have been changed by different users, individually. Each user could annotate their document by providing shapes and artworks, each of which may include text. The proposed scheme is based on storing the changes made by each user in a separate file for that user. Experimental results demonstrate the efficiency of the proposed scheme in terms of reducing the utilized storage space. Particularly, the proposed scheme is more efficient when the number of users or file size increases.
