Blockchain Data Authentication for Efficient Secure Document Cluster Validation

Abstract

The key issues in document authentication for banks and other businesses are in storage, retrieval and access to data. Hence came block chain technology to solve these problems in storing and accessing of data. Block chain technology provides a common shared platform from where to store, retrieve and access documents. The very nature of the technology is in the distributed, shared, open ledgers, verifiable by all. In today’s world, fake documents are epidemic and as most of you know there is no trouble in getting fake documents. Document authentication on block chain technology eliminates the third party thus limiting the cost of transaction on the network. Under blockchain, the documents are securely placed that only authorized person can access using their private keys. Block chain technology stores data in a form that cannot be altered. When a user presents a document, the technology converts or encodes the document into a cryptographic digest or cryptographic hash. This is done through cryptography which involves SHA-256 encryption of data using a hash function. So data becomes unalterable. It is practically impossible to hack. There will be no scalability issue anymore as transaction time taken could be as quick as few seconds. Today, the document authentication is no more strenuous and also immune to faulty representations via blockchain technology. Under blockchain technology, the documents to be verified are set on a distributed ledger. It is not the digital copy rather a cryptographic copy that is stored on the blockchain network.
