An Improved End to End System for Sharing and Managing Data in Cloud Storage

Cloud Computing is one of the emerging area in modern times. It is providing excellent facilities due to its adaptable infrastructure and features, but the issues related to trust management and security are key challenges in various applications. Whenever data or information is shared or transmitted from one host to another in cloud storage there is a need for security and trust assurances to prevent data from unauthorized hosts. In this article we present a survey which addresses the various challenges of cloud storage along with the different trust computation models to identify important research issues in the hotfoot growing area of computer technology. In order to resolve those issues the proposed methodology incorporates the trust evaluation and Digital Envelope techniques for preserving data against the un-trusted hosts and networks.
