The trend of digital information transformation has become a topic of interest. Many data are threatening; thus, protecting such data from attackers is considered an essential process. Recently, a new methodology for data concealing has been suggested by researchers called coverless steganography. Coverless steganography can be accomplished either by building an image database to match its image subblocks with the secret message to obtain the stego image or by generating an image. This paper proposes a coverless image steganography system based on pure image generation using secret message bits with a capacity higher than the other traditional systems. The system uses the secret message to generate the stego image in the form of one of the Intelligence Quotient (IQ) games, themaze. Firstly, a full grid is generatedwith several specific rows and columns determined fromthe number of bits of the secretmessage. Then, these bits are fed to the full grid to formthemaze game stego image. Finally, the generatedmaze game stego image is sent to the recipient. The experimental results, using the Bit Error Rate (BER), were conducted, and confirmed the strength of this system represented by a high capacity, perfect performance, robustness, and stronger hiding system compared with existing coverless steganography systems.
