BANKING CLOUD WITH BLOCKCHAIN SECURITY AND ERROR RECOVERY PROCESS

In the cloud, single or distributed databases can store data in a variety of ways, but individual database clients can only store data on one server. Security, consistency, availability, and bottlenecks still remain problems with a single database, regardless of how easy it is to manage data. Distributed databases address these issues by storing data on several servers simultaneously so that clients may access it concurrently. The data is dispersed widely and accessible from everywhere at any time. AES (Advanced Encryption Standard) and 3DES (Triple Data Encryption Standard) are two encryption algorithms that user can use to protect the data (Triple Data Encryption Standard), since several copies of the data are stored on other servers, so clients can easily access replicas even if the original is destroyed due to concurrent access. Different encryption techniques can be used on different types of data to increase the security of highly sensitive data. A recovery process is also launched if it is found that the data has also been altered. Whenever a cloud instance fails, it is automatically fixed as a result. This architecture provides data security and eliminates single points of failure by eliminating single points of failure. It is possible that clients in this architecture are unaware of the encryption method that protects data and the cloud server instance which delivers it. As a result, a single cloud database design offers better security, consistency, and availability.
