Abstract: Information security is critical to the development of modern internet technologies. The features of blockchain technology such as distributed approaches, decentralized mechanism, password mechanism and scripted mechanism present a completely new perspective for the development of internet information security technology. Cloud storage, like any other untrusted environment, requires the ability to secure shared information and ensure data privacy and reliability. The traditional solutions such as encryption have not been successful in preventing software bugs and misconfiguration issues. In this study, we present the framework of a blockchain-based public key encryption algorithm to ensure the privacy of user’s data at the infrastructure layer of the cloud platform. This technique encrypts the data to cipher form and then incorporate the Cipher-texts into hash codes as a digital signature on blockchain ledger to guarantee data integrity. The results depict an outbreak in the data security as cloud storage of cloud technologies.
