Blockchain Technology in Digital Certificate Authentication

The paper presents the concept of the association of digital signature technology with the currently trending blockchain technology for providing a mechanism which would detect any dubious data and store it in a place where it could be secure for the long term. The features of blockchain technology perfectly complement the requirements of the educational fields of today's world. The growing trend of digital certificate usage makes it easier for a dubious certificate to existing, among the others hampering the integrity of professional life. Association of hash key and a time stamp with a digital document would ensure that a third person does not corrupt the following certificate. The blockchain ensures that after verification, nobody else misuses the data uploaded and keeps it safe for a long time. The information from the blockchain can be retrieved at any moment by the user using the unique id associated with every user.
