Desenvolvimento de um software para verificação de autenticidade de documentos por meio de dispositivos móveis

Abstract

The increasing computers popularization and many other electronic devices increases the emission of printed documents and mainly in the digital documents. There is concern of the Instituto Federal do Triangulo Mineiro (IFTM) to create a secure mechanism that can prevent falsification and improper alteration of documents. Looking the creation of an offline tool that is able to validate the documents issued, with the aim of improving the document validation process, a software was developed capable of placing the textual content of the document. Using a reduced character table it is possible to generate a saving of a few bits per character resulting in a form of compression and also of encryption. After treating the text and generating a QR Code (quick response code) for insertion in the document, being a QR Code every 1200 characters, it will be possible through the application that the user can read and compare the textual data contained in the QR Code and verify that the document has not changed, thereby performing a validation as to its authenticity.
