Build Your Own Image Steganography Tool in C — 3 Techniques Explained 🖼️

In this video, I walk you through three different image steganography techniques - from the simple and fast LSB method to more advanced FFT and DCT embedding. You'll see visual demos of how each works, plus a quick look at Hamming error correction for making hidden data more resilient to real-world changes like compression or resizing.
