Abstract

Cloud computing is a method for delivering information technology (IT) services in which resources are retrieved from the Internet through web-based tools and applications, as opposed to a direct connection to a server. Rather than keeping files on a proprietary hard drive or local storage device, cloud-based storage makes it possible to save them to a remote database. In the proposed project we are going to deal with data security in cloud .The key feature of our project is to create a system which work with data security, access control and Group Management. For this we examine the number of algorithms and techniques to implement our system and now we are going to use some of them to implement our system.

Introduction

Cloud storage is a simple and scalable way to store, access, and share data over the Internet. Cloud storage is a service model in which data is maintained, managed, backed up remotely and made available to users over a network .In this data can be shared in secured manner, in cloud it can be achieve secure data sharing in dynamic groups. Cloud computing offers an infinite storage space. In our scheme, secured data sharing can be protected from collusion attack [1]. The key aim of the proposed work is to include the four factors in the proposed approach of the system

Conclusion

In this, we design a secure anti-collusion sharing of the data for dynamic groups in the cloud. Private key of the group member not need to be updated or recomputed when the user joins or leaves the group. Revoked user are unable to get their original data from the cloud after their revocation. This scheme can achieve secure user revocation.In this paper there is no need for Certificate Authority that is no need of group manager, which reduces the overhead of system.
