Abstract

Objective: The objective of this paper is to propose a cloud system which ensures high security for storing and sharing user files in the cloud and efficient utilization of cloud storage space. Methods: The different methods that can be implemented to achieve a stable and efficient system was incorporated from literature review. Details regarding the working of various compression and encryption standards were extracted to build the proposed system. Findings: The internet is growing day by day and can be easily accessed by everyone and everywhere. This increases the need to store and transfer digital data, which would allow users to access data without the hassle of carrying a storage device. The focus of this paper is to propose a technique which ensures the data uploaded in the cloud is secure and also that the storage space is used efficiently. The proposed paper also explains sharing data in a secured format and also how data can be downloaded with minimum bandwidth, which is useful while operating in places where there is minimal internet speed. Applications/Improvement: In today’s cloud era confidential records or documents involving financial and management information can be securely shared in compressed format.
