Image watermarking in wavelet domain is a challenging problem as it includes a proper selection of wavelet transforms as well as sub‐bands for accurate embedding and recovery of watermarks. However, selection of a suitable wavelet transform for multiple image watermarking is an area of great interest. Therefore, in this work, a multiple watermarking technique using combination of redundant discrete...
In this paper, a robust image steganography technique based on redundant discrete wavelet transforms has been proposed. Steganography is the process of hiding one medium of communication like text, audio and image within another. The proposed steganography algorithm uses blind recovery approach. We have tested the proposed method on different cover and payload images. Simulated results are analyzed...
