Abstract

Applications of blockchain might be related to healthcare and commercial sector. Need of such application is growing in smart cities. It has been observed that its implication are quite complex. The goal of the blockchain technology is to make it possible to store and distribute digital data without the risk of it being altered in transit. A blockchain provides the basis for immutable ledgers or transaction records that cannot be edited, erased, or destroyed. The term “blockchain” is often used to refer to DLT. Hashing is a sophisticated procedure that cannot be modified or reversed. When it comes to data security, it's all about safeguarding your information against unwanted access and corruption at every stage of its lifespan. Encryption, hashing, tokenization, and key management methods are all part of the data security process. The term “identity and access management” refers to all of the methods and technologies used inside a business to identify, authenticate, and authorize users to access services and systems within that business or other associated businesses.
