Difference expansion and histogram shifting methods are two popular hiding strategies that have been widely used in many researches. For example, Hong and Chen developed a reversible hiding method based on interpolation and histogram shifting. The image quality of their scheme is exceptional; however, their scheme needs to keep and transmit two peak points(More)
Lee and Huang proposed a dual-image reversible data hiding method to protect the confidential data in 2011. The image quality obtained by the method is good because each pixel in the cover image is modified by only adding or subtracting one to generate the stego image. However, in their method, each set of four cover pixels can only embed five confidential(More)
In 2010, Shiu et al. proposed three DNA-based reversible data hiding schemes with high embedding capacity. However, their schemes were not focused on DNA modification rate or the expansion problem. Therefore, we propose a novel reversible data hiding scheme based on histogram technique to solve the weaknesses of Shiu et al.’s schemes. The proposed scheme(More)
One of the major challenges in assessing the potential metal stress to aquatic organisms is explicitly predicting the internal dose in target organs. We aimed to understand the main sources of copper (Cu) accumulation in target organs of tilapia (Oreochromis mossambicus) and to investigate how the fish alter the process of Cu uptake, depuration, and(More)
Purpose. To investigate the mechanisms underlying the regional variations in drug transport into human stratum corneum (SC) of two model compounds of different lipophilicity and molecular size, 4-cyanophenol (CP) and cimetidine (CM), in vivo by non-invasive, quantitative attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy.(More)
Stromal cell-derived factor-1 (SDF-1) (CXCL12) has been observed to promote laryngeal and hypopharyngeal squamous cell carcinomas (LHSCCs) invasion through cooperation with its receptor CXCR4. Here, we further explore the angiogenesis mechanism induced by SDF-1/CXCR4 interaction in LHSCCs. Immunohistochemistry (IHC) reveals the significant correlation(More)
The reversible information hiding technique is to embed secret information in multi-media. Through extraction algorithm, the concealed information can be extracted and the original host media can be totally recovered. Coltuc et al. developed a simple and efficient reversible hiding scheme based on reversible contrast mapping (RCM), which does not need(More)
This paper presents two secret hiding schemes based on absolute moment block truncation coding (AMBTC). One is for embedding secrets into complex blocks and the other one is for smooth blocks. As for the smooth blocks, the small variation of the block is adopted to define the embedding rule to minimize the distortion after data embedding. As for the complex(More)
