As the primary concern in conventional steganography techniques is to make the algorithm immune to steganalysis, their primary focus is on imperceptibility. This paper discusses Zero-steganography, an imperceptible and un-detectable data hiding technique that does not require any steganalysis. The proposed algorithm hides the data based on a relationship between characteristic matrix of the cover image, chaotic sequence and payload; however, no change is made to the cover image. The proposed algorithm is analyzed for robustness against three attacks — low-pass filtering, noise and JPEG compression. Our results show that the proposed algorithm is robust against these attacks with Bit Error Rate (BER) below 20% even for the highest attack intensities.
