The most common method for achieving 4-secret image steganography is .
Here's a step-by-step overview:
At its core, this method relies on the fact that humans cannot perceive very small changes in color intensity. 9.1 4 secret image steganography
While digital screens use RGB, printing uses CMYK—a 4-channel model.
As digital forensics advances, so too must the sophistication of these embedding techniques, ensuring that the "invisible" truly remains invisible. The most common method for achieving 4-secret image
: To retrieve the secret, a program checks if the cover pixel's value is even (LSB is 0) or odd (LSB is 1) and reconstructs the hidden image accordingly. Key Programming Concepts
