We propose a fractal image generation method for data hiding using chaos theory. Chaos is an unpredictable behavior which arises on the dynamical system in turns explains the non-linearity and randomness. The initial condition acts as a key which is generated by the PRNG. The fractal image generation method is used to generate the fractals; while generating the fractal itself we have to hide the data. It uses the difference equation i.e., Fibonacci series for data hiding. If the initial value is identified wrongly then chaotic behavior arises in the system that may lead to chaos. It is very difficult for the steganalysis to break the data. The generated fractal images are watermarked and it can be used as a digital signature for any online applications.
