Práctica PT: Esteganografía
Description

En este proyecto, los estudiantes implementarán una forma de criptografía conocida como esteganografía.

La esteganografía es el arte y la ciencia de ocultar mensajes secretos de tal manera que nadie aparte del receptor previsto sabe sobre la existencia del mensaje. En información digital, la esteganografía es la práctica de ocultar un archivo, mensaje, imagen o video dentro de otro archivo, mensaje, imagen o video.

Objective

Students will be able to…

  • Explain the connection between cryptography and encoding information digitally
  • Create a program that encodes secret information in the binary pixel data of an image

Enduring Understandings

This lesson builds toward the following Enduring Understandings (EUs) and Learning Objectives (LOs). Students should understand that…

  • EU 1.1 Creative development can be an essential process for creating computational artifacts. (LO 1.1.1)
  • EU 1.2 Computing enables people to use creative development processes to create computational artifacts for creative expression or to solve a problem. (LOs 1.2.1, 1.2.4, 1.2.5)
  • EU 2.1 A variety of abstractions built on binary sequences can be used to represent all digital data. (LO 2.1.2)
  • EU 2.2 Multiple levels of abstraction are used to write programs or create other computational artifacts. (LO 2.2.1)
  • EU 3.1 People use computer programs to process information to gain insight and knowledge. (LO 3.1.2)
  • EU 5.4 Programs are developed, maintained, and used by people for different purposes. (LO 5.4.1)
