Enhanced Data Integrity Auditing and Sharing Scheme with highly confidential data for Secure Cloud Storage.

Cloud Computing provides a user -based data storage and calculation method. We can use cloud computing to maintain privacy and confidentiality of cloud data. We have to pay for use and requires an Internet connection. Due to the lack of data security cloud, it provides an effective way to save data in encrypted form in the cloud. The aim is to prevent the patient’s abuse and strive to require data as the patient requires. Serious safe and protected concerns are too much of the problems that stand in the way of a wide acceptance of the framework. IT application plays an important role in health and care for patients. Cloud users upload personal or confidential data to the cloud data center. In previous electronic health record systems, they cannot handle dynamic changes related to a number of users. Our main motive is to protect data from unauthorized access. In the previous system file, file recording operations are not carried out safely and abused for data due to lack of security. The cloud file may contain some sensitive information, and sensitive information should not be exposed to others when the cloud file is shared and encryption of the entire shared file can make sensitive information.
