Secure Cloud Storage based on integrity Auditing and Data sharing with Sensitive Information Hiding

Now a days cloud storage is used to store big data and provide a storage platform for businesses and individuals and also with cloud storage system user can store and access data remotely. It avoids the commission of a large number of users to manage and purchase software and hardware. In cloud storage, key disclosure is one of the security issues. In a commonly used cloud storage system, Electronic Health Records (EHR), Military information contains sensitive information, and this sensitive information can be exposed when sharing cloud files. Using encryption techniques, file sharing is hidden from other users. To solve this type of problem, we propose remote data integrity auditing techniques; this system can hide sensitive information when sharing data in the cloud. To do this here, we use sanitized to sanitize data blocks that are considered sensitive file information and then convert those block signatures to valid ones for sanitized files. Signatures are used to verify the integrity of the sanitized file in the integrity audit phase. These techniques are able to secure cloud file storage and sharing as well as hide sensitive information. This technique is based on Identity Based Cryptography.
