Summary:One of the main problems in image steganography is to achieve higher payload capacity to save bandwidth. To address this challenge, in recent years, put forward a variety of steganography technology. There is always a trade-off between capacity and image quality. This paper proposes a discrete cosine transform based approach to achieve maximum load capacity while maintaining a PSNR higher than 25 db. The maximum capacity obtained in this work is 21.5 B.P. while keeping the image signal-to-noise ratio of 38.24 dB. These results have been compared with existing schemes.
