This study presents a simple method for high-hiding capacity. The basic concept uses a modulus operation. The proposed method has the following advantages: (1) the proposed method outperforms the simple LSB substitution method given the same range (0–m − 1) of data digits in the embedded data; (2) the proposed method achieves good image vision quality without the need for post-processing; (3) t...

Nowadays, the security of images or information is very important. This paper introduces a proposed hybrid watermarking and encryption technique for increasing medical image security. First, secret encrypted using Advanced Encryption Standard (AES) algorithm. Then, report patient embedded into with Least Significant Bit (LSB) After that, concealed in cover image, Kekre’s Median Codebook Generat...

In this paper a new configuration of up converter is presented. In this circuit, the LO and RF (LSB) frequencies are rejected thanks to a distributed and balanced circuit. Eight GaAs PHEMTs with a gate-length of 0.25 μm are used. A conversion gain of -6 dB and a rejection over 6 dB on LO and RF (LSB) are obtained.

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...

IMPORTANCE There are limited data on the use of the supraclavicular artery island flap (SCAIF) for parotid and lateral skull base (LSB) surgery. This flap can be an important reconstructive tool for these procedures. OBJECTIVE To describe the use of the SCAIF for parotid and LSB surgery and its success, as well as important technique modifications for successful use of the flap in this settin...

In edge adaptive image steganography based on LSB matching revisited algorithm (EAMR for short in this paper), the secret message bits are embedded into those consecutive pixel pairs whose absolute difference of grey values are larger than or equal to a threshold T. Tan et al. [1] pointed out that since those adjacent pixel pairs can be located by the potential attackers, the pulse distortion i...

A dual image technique is used as one of the data hiding method. Dual image copies an image to two same images. Through two images to embed or extract secret data, this technique significantly enhances image quality. A dual image technique is good or bad depending on the merits of its algorithm. This paper proposes a method to improve Lu et al. scheme. They use two pixels as a pair and choose t...

This paper deals with the detection of hidden bits in the Least Significant Bit (LSB) plane of a natural image. The mean level and the covariance matrix of the image, considered as a quan tized Gaussian random matrix, are unknown. An adaptive statis tical test is designed such that its probability distribution is always independent of the unknown image parameters, while ensuring a high probabil...

0 . 1 8 ~ CMOS process. The DAC is optimized for circuit calibration in large ASICs and occupies 0.01034 mm’ (1 IOW x 9 4 ~ ) of die area. Creative layout and current mirroring techniques are implemented to minimize area while providing output current with sufficient headroom. The measured DNLfiNL is better than 0.7/0.75 LSB and OH2 LSB for 1.8V and 1.4V power supplies, respectively. The DAC co...
