High hiding capacity steganography method based on pixel indicator technique
Vahid Rahmani, Mostafa Mohammadpour · 2017
Image based steganography utilize the images as cover media to hide secret data. So far several methods have been presented in image steganography. Many of these methods use embedding in least significant bits of pixels. Steganography should be strong enough to hide confidential data and does not cause major changes in the image. The use of least significant bits will not lead to major changes in the image. One of the major challenges of image steganography is the volume of storable data resistant to changes and lack of recognition of hidden data. In this paper a steganography method in a 24-bit color RGB format image is presented to store high-volume text data. The results of the tests show that the proposed method has high storage capacity compared to other methods based on embedding in least significant bits of pixels.
