Proyecto nuevas tecnologías para transmisión de video sobre IP y transmisión de IP sobre DVB: desarrollo de una herramienta esteganográfica de uso didáctico para envío de texto oculto y cifrado en archivos de video mp4.

Abstract

Nowadays, digital tools help in multiple activities that are carried out on a daily, like education, which is seen with better results if these tools are applied as a complement to theory. The present work focuses on a steganographic didactic tool for the subject of Network Security, with the purpose of showing that the information can be hidden; This application uses algorithms that allow access to the bits of an MP4 video file and with the use of steganographic techniques, secretly place the information in such a way that it is unreadable and at the same time undetectable to the naked eye.In the first chapter, each of the concepts to be used is detailed in depth and fundamental issues are addressed to understand the use, operation of steganography and with which algorithms these actions can be carried out. This also details the video formats and their containers such as MP4, which we will use to hide that information
