DATA EMBEDDING INTO THREE - DIMENSIONAL IMAGE ENCRYPTION BASED ON REVERSIBLE DATA HIDING IN CLOUD
Abstract
The growth of technology nowadays have too many service providers are provides a separate storage space in their cloud. Outsourcing database is a very demanding task for safeguarding the confidential data, documents, and privacy images in the cloud. This sensitive information should be encrypted before outsourcing to the trusted third party (TTP), which formulates an effectual information utilization of challenging task. Although, the traditional security system having several encryption algorithms to prevent the database from the unauthorized users or attackers. The existing encryption algorithm has not supported the large factorization of keys on the database. This paper proposes the confidential data to be reversibly embedded data into a cover image with the rotation and shearing of sides on a magic cubes, which is used for validating the authorized users. The cover image is partitioned into a number of cubes and fully homomorphic encryption is applied to gain the encrypted cover image. The predefined pixels are compared and calculated the distance range of pixels to identifying original image spot regions. They were no changes in the pixels, the user has a permission to extract the data from the image otherwise denied the access. The attacker doesn?t know the content of hidden data behind the image even they have a success in the login phase, these secret data extracted completely detachable from the decrypted 3D magic cube image. At last, the confidential data and images are haul-out without an error. The experimental result shows the durability and efficiency of the images in the proposed method.
