In this lesson, students will learn how to manipulate images programmatically using JavaScript to perform steganography. Through a series of activities, they will build a program that can encode a secret message within an image and later decrypt it. The lesson covers image loading, encryption using pixel color manipulation, and decryption.
Students will be able to:
- Load and display multiple images using JavaScript.
- Implement an encryption algorithm by modifying pixel values.
- Develop a decryption function to extract hidden messages from images.
- Understand the principles of steganography and its applications.
These are all the activities included in the lesson
