An enhanced AMBTC for color image compression using color palette
Digital image has been used in various fields as an essential carrier. Many color images have been constantly produced since their more realistic description, which takes up much storage space and network band...

Enhanced stego-image quality and embedding capacity for the partial reversible data hiding scheme
Recently, Jana et al. proposed the partial reversible data hiding (PRDH) based on (7, 4) Hamming code, which deals with three images: the original image (OI), the cover image (CI), and the stego image (SI). Th...

Generalizing Hamming+k data hiding by overlapped pixels
Matrix coding based data hiding (MCDH) using linear codes (syndrome coding) is an efficient coding method for steganographic schemes to improve their embedding efficiency. Hamming code data hiding (HDH) is a w...

Dual-source discrimination power analysis for multi-instance contactless palmprint recognition
Due to the benefits of palmprint recognition and the advantages of biometric fusion systems, it is necessary to study multi-source palmprint fusion systems. Unfortunately, the research on multi-instance palmpr...

Data hiding based on overlapped pixels using hamming code
Most data hiding schemes change the least significant bits to conceal messages in the cover images. Matrix encoding scheme is a well known scheme in this field. The matrix encoding proposed by Crandall can be ...

Open AccessWatermark with DSA signature using predictive coding
This paper presents a predictor-based watermark scheme that embeds secret bit streams and a DSA signature into an image. For the copyrighting of digital media, a DSA signature is appropriate as a watermarking ...

Data hiding by an improved exploiting modification direction
This paper represents an improved data hiding scheme, CIE, which uses a codebook to improve the Exploiting Modification Direction (EMD) embedding scheme. In our scheme, one secret (2 n + x ...

Steganography Based on Low Density Parity Check(LDPC)
We propose a data hiding scheme based on Low Density Parity Check(LDPC) codes. Our proposed theoretical point of view, the blind watermarking can be transmitted through a noisy channel. Matrix encoding propose...

Data Hiding Based on Compressed Dithering Images
In this paper, we proposed data hiding method for halftone compressed images based on Ordered dither BTC(block truncation coding) [7]. BTC[9] is a simple and efficient image compression technique. However, it ...
