A new adaptive method for hiding data in images
LSB method is one of the well-known steganography methods which hides the message bits into the least significant bit of pixel values. This method changes the statistical information of images, which causes to have an unsecured channel. To increase the security of this method against the steganalysis methods, in this paper an adaptive method for hiding data into images will be proposed. So, the...
متن کاملA Robust Method for Data Hiding in Color Images
In this paper, we propose a methodology for embedding watermark image data into color images. At the transmitter, the signature image is encoded by a multiple description encoder. The information of the two descriptions are embedded in the host image in the spatial domain in the red and blue components. Furthermore, this scheme requires no knowledge of the original image for the recovery of the...
متن کاملData Hiding in Medical Images
This paper presents an efficient technique to hide text information in 3D medical images such as MRI and PET. It embeds text information only in the non-anatomical pixels. It ensures that no anatomical part of the 3D medical image gets contaminated. It makes the retrieval of 100% data. The technique has been tested on several MRI and PET images.
متن کاملHiding Data in Halftone Images
Most recent papers about visual cryptography for halftone images are dedicated to get a higher contrast decoded image. However, the hidden visual pattern often blends into the background image and leads to a confused image. In this paper, we propose an improved method for halftone image hiding. By using the proposed method, the background image can be eliminated and the hidden visual pattern ca...
متن کاملData Hiding Method with Quality Control for Binary Images
Secret data hiding in binary images is more difficult than other formats since binary images require only one bit representation to indicate black and white. This study proposes a new method for data hiding in binary images using optimized bit position to replace a secret bit. This method manipulates blocks, which are sub-divided. The parity bit for a specified block decides whether to change o...
