A Novel High Capacity Data Hiding Algorithm using Salt and Pepper Noise

In recent years, data hiding using images has become a hot topic for research. Steganography is the art of hiding data in a seemingly innocuous cover medium. In this paper, a novel algorithm is proposed by merging two concepts of data hiding and salt-pepper noise removing. Two procedures are involved in the new algorithm, embedding by adding noise, and extracting by removing noise. The input for the first procedure is a cover image and secret data, while the output is a stego image. In the second procedure, the input is the received stego image, and the output is the cover image and the secret data. The experimental results show that the proposed approach has a better performance in terms of the embedding rate compared to that of the other approaches.
