-This paper introduces a new, principled approach to least significant bit (LSB) steganography in digital signals such as images. It is shown that privacy protection of medical images with information using histogram shifting based reversible data hiding.First of all, the patient’s privacies need to be preserved.Therefore, embedding secret data into the medical images would be one of the useful...

In this paper, proposed an advance approach for dynamic data protection using LSB and hybrid approach. Steganography is the art of communicating a message by embedding it into multimedia data. The proposed method for replacing one or two or three LSB of each pixel in video frame and apply Advance encryption standard (AES). It becomes very difficult for intruder to guess that an image is hidden ...

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...

This paper proposes a new histogram shifting-based reversible watermarking method. In contrast to other almost methods that need to use simultaneously the watermarked image and some image-dependent side information to restore the watermark and the original image, our method can do above restorations without any auxiliary information. Such methods are called free from side information. Our solut...

Steganography is the act of hiding a message inside a container in such a way that can only be detected by its intended recipient. The container can be of different types text, image, audio and video. With the explosion of Internet and reach multimedia content, use of video as a container has become topic of interest for the research fraternity. Though, with the use of internet it has become mo...

Digital images are increasingly being used as steganographic covers for secret communication. The Least Significant Bit (LSB) encoding is one of the most widely used methods for embedding a message in a digital image. However, the direct application of LSB encoding is vulnerable to steganalysis. For example, RS steganalysis is very efficient in detecting the presence of a message in a digital i...

Steganography is an ancient art of conveying message in a secret way that only the receiver knows the existence of message. Steganalysis is the art of detecting the message's existence and blockading the covert communication. The least-significant bit (LSB) insertion method, which uses fixed k LSBs in each pixel to embed secret message, is the most common and easy one to hide message in an imag...

In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image. This new algorithm is using LSB by inversing the binary values of the watermark text and shifting the watermark according to the odd or even number of pixel coordinates of image before embedding the watermark. The proposed algorithm is flexib...

This paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image. This new algorithm is using the third and the fourth least significant bits (LSB) technique and shifting the watermark of pixel coordinates of image before embedding the watermark. The proposed algorithm is flexible depending on the length of th...

To provide higher embedding capacity without sacrificing the imperceptibility, a novel steganographic technique based on nine-pixel differencing with modified Least Significant Bit (LSB) substitution is proposed. The image is divided into 3×3 non-overlapping blocks. In each block the average difference value is calculated. Based on this value the block is classified to fall into one of the four...
