Abstract:

Sending encrypted messages would always attract third parties' attention, i.e. crackers and hackers, likely triggering attempts to break and expose the original messages. Steganography is applied in a digital environment to mask the presence of contact by concealing a hidden message within another. The goal of this paper is to develop a suggested method for providing a high-level safety system by implementing and developing a steganography system to hide data in an image cover. This is a more complicated system. It implemented the system at two embedding levels, and this is a high level of security problem since two extraction levels were needed to extract the hidden data. In the frequency domain, the framework is implemented using wavelet domain transformation. The principle of using transformation in the proposed method is due to the results of previous published works that showed that hiding in the frequency domain is more efficient than hiding in the time domain, due to the compactness and robustness of such transformations. In this proposed method, a Haar Wavelets Transformation (WT)
