A Novel approach for Secure Digital Signature using Blockchain Technology

Abstract

The certificates that are granted by authorization are insecure because of lack of authentication. We use block chain technology, which, like digital signatures, verifies users' identities and access authorizations, to combat certificate forgery. The open distributed ledger known as a block chain guarantees that no transaction can ever be altered and contains unchallengeable information in a highly protected and encrypted manner. In accordance with a high requirement for the method that can guarantee that the information in such a certificate is genuine, the document must originate from a reliable source and not be counterfeit. Interplanetary record framework utilizes the substance address to only personality each individual document in an in general namespace including all processing gadget. A two-dimensional barcode known as a quick response (qr) code stores data in the form of black and white dots. On a white background, the system consists of black squares that can be captured by an imaging device like a camera and are arranged in a square framework.
