  The use of physical documents is inconvenient and inefficient in today's
world, which motivates us to move towards the use of digital documents. Digital
documents can solve many problems of inefficiency of data management but
proving their authenticity and verifying them is still a problem. This paper
presents a solution for this problem using text extraction, digital signatures
and a correlation score for a set of documents. The paper discusses the impacts
and advantages of the proposed technologies against other possible technologies
that could serve the same purpose.
