Secure and Efficient Dual Access Control Scheme in Cloud Based Data Storage and File Access with QR Code

Abstract

Cloud-based data storage service has drawn increasing interests from both academic and industry in the recent years due to its efficient and low cost management. Since it provides services in an open network, it is urgent for service providers to make use of secure data storage and sharing mechanism to ensure data confidentiality and service user privacy. To protect sensitive data from being compromised, the most widely used method is encryption.  However to compare present situations users can take more time getting the file accessing. And also user get the key and the key can shows directly, this type of accessing can have possible to attack. So, we are implementing new methodology. Adding email authentication at users’ login, and key forward to mail, in Dual accessing process adding Co-Owner option for an owner uploaded file. This few features can increase security and reducing the time efficiency.
