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...

Exploiting error control in matrix coding-based data hiding over lossy channel
A steganographic scheme, matrix coding-based data hiding (MCDH), is constructed from covering function to enhance embedding efficiency, and, meanwhile, decrease the required changed bits. However, the MCDH may...

Reversible data hiding scheme with edge-direction predictor and modulo operation
Since the first histogram shifting technique was proposed by Ni et al., many histogram based data hiding methods were proposed to improve their scheme. One of the methods is using difference value between cove...

A real-time secret image sharing with fairness
When traditional secret image sharing techniques reconstructed the secret, they input the shares over t. While less than t shares can know nothing about the secret, the problem arises when there are more than t s...

Lossless data hiding for absolute moment block truncation coding using histogram modification
This paper presents a lossless data hiding method for an absolute moment block truncation coding (AMBTC) images, which is a compressed grayscale image. It is not easy to hide secret data in an AMBTC-compresse...

Article
Adaptive real-time reversible data hiding for JPEG images
Data hiding used to embed data, such as copyright information, into various forms of media such as image, audio, or text with a minimum amount of perceivable degradation to the “host” signal. Therefore, in man...

Secure medical images based on data hiding using a hybrid scheme with the Hamming code, LSB, and OPAP
Some medical accidents in hospitals are related to mismanagement of medical images X-ray and computer tomography (CT). A counterfeit medical image leads to medical accidents. Thus, security of medical images i...

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 ...

Design a new visual cryptography for human-verifiable authentication in accessing a database
Visual cryptographic scheme (VCS) has an attractive property of decoding that can be performed directly by the human visual system without any computation. This novel stacking-to-see property of VCS can be sec...

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 ...

New ID-Based Proxy Signature Scheme with Message Recovery
In 2012, Singh-Verma proposed an ID-based proxy signature scheme with message recovery. Unfortunately, by giving two concrete attacks, Tian et al. showed that Singh-Verma’s scheme is not secure. This paper pro...

Data Hiding Based on Palette Images Using Weak Bases of Z2-Modules
Many steganography schemes were invented for the purpose of safe communication. Such previous schemes often show good and reasonable performance, however, few have been based on paletted images; it is not easy...
