Demonstration for LSB Data Hiding Technique Using (a) Classical Binary, (b) Generalized
Fibonacci Sequence, (c) Prime and (d) Natural Number System decompositions.
Number of Bitplanes available to embed data for (a), (b), (c) and (d) are 8, 12, 15, 23 resp.
The distortion in the stego image after embedding stego-text (message to be hidden) in
cover image is in the order (a) > (b) > (c) > (d), i.e., distortion decreases with change in
Number System, s.t. higher bit planes can also be used for Prime and Natural
decompostion techniques.
NOTE: Since the algorithms apply transformation functions that operate on each pixels
and converts to a different number system (Fibonacci or prime), then hides stego (secret)
message bit in a specific bitplane and finally converts it back to classical binary number system,
it may take a few seconds to apply the image transformation function and generate the
stego-images, so please be patient.
