Blockchain and Data Integrity Authentication Technique for Secure Cloud Environment

Nowadays, numerous applications are associated with cloud and user data gets collected globally stored in units. In addition to shared storage, computing technique offers multiple advantages for the through different distribution designs like hybrid cloud, public community private cloud. Though cloud-based solutions highly convenient users, it also brings a challenge i.e., security of shared. Hence, current research paper, blockchain integrity authentication is developed an efficient secure operation process. Blockchain technology utilized this study enable which not only empowers but avoids threats attacks. Additionally, limit unwanted access storage unit. The major objective projected empower environment. To improve proposed process, cuckoo filter Merkle Hash Tree (MHT) utilized. methodology was validated using few performance metrics such as processing time, uploading downloading consensus waiting initialization overhead. method compared conventional techniques outcomes establish supremacy method.
