Secure Blockchain Banking Cloud with Error Recovery Processes

Cloud computing technology is an excellent source for increasing data management capacity and providing a variety of services. Clients can access a variety of services via the internet using this technology. This Cloud technology provides several advantages to banks, including lower costs, more data processing capability, and better competence in financial services. Financial firms would use cloud services with greater efficiency and flexibility as needed. However, many firms are hesitating to employ this technology because of security concerns. Keeping data safe in the cloud is becoming more and more important. The paper aims to propose a solution to the aforementioned problem using blockchain and biometrics. Biometrics is a digitalized method for recognizing people based on physiological characteristics. Biometrics and cryptography might be used to make the cloud server extra secure. The cloud-based protected data is secured using bio-cryptography concealment. The method secures the protection and deciphering of data in the cloud by using biometrics as the primary component. We discuss how to make the biometric system safer by utilizing cloud computing, as well as how to improve its performance so that criminals cannot access your data. Biometric authentication is a viable solution for cloud services. We will explore how to construct a cryptographic technique within a blockchain to overcome these concerns. Blockchain technology will improve data security by utilizing cryptographic keys. The system also manages error recovery, which leads to the failing cloud instance being immediately identified and corrected.
