Prototype of E-Document Application Based on Digital Signatures to Support Digital Document Authentication

Abstract

Abstract The purpose of this research is to develop a prototype of a web-based application that can be used to provide digital signatures on files or digital documents. This prototype uses a digital signature mechanism issued by the Ministry of Communication and Information of the Republic of Indonesia (KOMINFO). The results of the research conducted by using the alpha test showed that all functionalities in the application have been able to run well. While the authentication test shows that any changes made to a document that has a digital signature will invalidate the digital signature, which means that there are attempts to falsify documents and their authenticity can be identified. This is because in documents that have the digital signature will have a certain hash value which if the document is changed or modified, then the hash value will change. This is what determines whether a document is still original or has been modified its contents, namely by comparing the hash value contained in the document.
