Abstract

The use of electronic documents by many companies and institutions is expected to increase in the coming years. The greater the use of electronic documents, the greater the risk of forgery and alteration of electronic documents. Electronic documents appear to be combined with tools that visually convert 0 and 1, but do not exist, and they exist in file form, so the document editor alone can falsify and falsify electronic documents. Currently, there are two ways to prevent forgery and alteration of electronic documents, either by using the authorized electronic document center to guarantee the contents and transmission of documents, or by using the point-in-time verification solution (TSA) at the time of electronic document generation. However, both measures have central problems and cost issues. To improve this problem, a distributed electronic document forgery and tampering prevention system was implemented by utilizing the technology of hyperleisure fabric, an open source private block chain.
