So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...

In this paper a novel approach towards LSB substituted data hiding in images has been proposed based on random bit substitution which not only improves the robustness and security of the watermarking scheme but also significantly improves the stego image quality which is visually indistinguishable from the original cover image. The the watermarked image shows marked improvement and greater resi...

Steganography is an art of hiding the secret message in a cover object without leaving a remarkable track on the original message. It is used to increase the security of message sent over the internet. In contrast to cryptography, it is not used to scramble the data but it is used to conceal the data in digital media. This review paper will deal with video steganography, cryptography, hash-LSB ...

In this paper, we propose a new algorithm of steganography to allow simultaneous hiding secret message and small-size image into an large-size image. To hide the secret message in small image we use the Least Significant Bit (LSB) substitution, and the method for hiding the image in the image cover use Discrete Wavelet Transformation (DWT). The proposed method results in increasing the secret m...

This paper presents a combined DWT and LSB based biometric watermarking algorithm that securely embeds a face template in a fingerprint image. The proposed algorithm is robust to geometric and frequency attacks and protects the integrity of both the face template and the fingerprint image. Experimental results performed on a database of 750 face and 750 fingerprint images show that the algorith...

A 10b multibit-per-stage pipelined ADC incorporating merged-capacitor switching (MCS) technique achieves better than 53 dB SNDR at 120 MSample/s and 54 dB SNDR and 68 dB SFDR for input frequencies up to Nyquist at 100 MSample/s. The measured DNL and INL are f0.40 LSB and f0.48 LSB, respectively. The ADC fabricated in a 0.25 pm CMOS occupies 3.6 mm2 active die area and consumes 208 mW under a 2....

We obtain a static spherically symmetric wormhole solution due to the vacuum expectation value (vev) of Kalb–Ramond field. The is background tensor field which produces local Lorentz symmetry breaking (LSB) spacetime. Considering non-minimal coupling between and Ricci tensor, we found an exact traversable sustained by matter sources with negative isotropic pressure. source satisfies energy cond...

I study the VLA HI survey of HII galaxies by Taylor et al. (1995, ApJS, 99, 427; 1996, ApJS, 102, 189) and the VLA HI survey of low surface brightness (LSB) dwarf galaxies by Taylor et al. (1996, in press) to investigate the role of galaxy interactions in triggering the bursts of massive star formation seen in HII galaxies. Comparing the two surveys, I find that HII galaxies have companions mor...

Human pluripotent stem cells (PSCs) are a promising source of cells for applications in regenerativemedicine.Directed differentiation of PSCs into specialized cells such as spinal motoneurons or midbrain dopamine (DA) neurons has been achieved. However, the effective use of PSCs for cell therapy has lagged behind.Whereasmouse PSCderived DA neurons have shown efficacy in models of Parkinson’s di...
