Data Integrity Proofs on Cloud Computing Using Blockchain

Cloud data deduplication can save cloud storage resources and network communication bandwidth, and improve cloud storage efficiency. In our project we develop the series of deduplication technologies that are proposed to achieve cloud data deduplication. In past, the traditional duplication technologies and scheme mainly implements data deduplication without providing data integrity verification, so it cannot be verified whether the cloud service provider correct stores user data. In our project we proposes a data integrity verification scheme of deduplication for cloud ciphertexts, including cloud ciphertext deduplication and cloud data integrity verification. In our project Data Integrity Proofs on Cloud Computing using Blockchain we adopted the signature method. In addition, our project ensures the privacy of cloud data, and satisfies the user data is secure and our result shows the higher efficiency.
