| Abstract | Most information hiding methods present in the literature have one general principle in common: they hide the secret message within an insignificant component, such as noise, of the cover or carrier. Most of these methods do not pay attention to the statistical properties of the noise components and change the statistical profile of the cover significantly hence leading to the simplicity of breaking the system by a passive attacker. In this paper an adaptive steganography algorithm is proposed that encrypts the secret message and spreads it in highly noisy image regions of a carrier image using spread spectrum and discrete cosine transform methods. A modified message embedding method is also introduced that is based on comparative blocks, transform and Bit Plane Complexity Segmentation (BPCS) embedding techniques to increase the data hiding capacity. Traditional techniques have limited data hiding capacities of up to 18% of the data amount of a carrier image. The integration of these techniques increased the hiding capacity to approximately 62%. |
