An Efficient Secure System for Data Integrity and Replication in Cloud

Abstract

The cloud computing is popular for the virtually storing data because it provides the big storage space and provides the portability and mobility functions. Even if data de duplication is main advantages in security and privacy concern occur as user’s confidential data are liable to both attacks insider and outsider. A convergent encryption method imposes data security while making de duplication possible. Traditional de duplication systems based on convergent encryption even though offer confidentiality but do not maintain the duplicate check on basis of differential rights. The cloud storage service (CSS) reuses total storage traction and maintenance. Hybrid cloud model is new deduplication constructions supporting authorized duplicate check. The proposed security models contain the illustration of security analysis model. as a proof of data contains the implementation framework of proposed authorized duplicate check scheme and conduct experiments using these prototypes the many de duplication methods are implemented in Hybrid Cloud system. Our proposed model is implemented for text file, pdf file, book, and image and video, it also verifies the confidentiality of private cloud
