For the instantaneity of real-time applications such as voice over Internet protocol (VoIP), the processing delay and efficiency need to be carefully considered. Matrix coding is a widely used coding scheme for steganography to improve the embedding efficiency which means the average hiding bits per covering bit change. In order to take full advantage of it, a classifying least-significant-bits...

This research paper proposes a secured, robust approach of information security using steganography. It presents two component based LSB (Least Significant Bit) steganography methods for embedding secret data in the least significant bits of blue components and partial green components of random pixel locations in the edges of images. An adaptive LSB based steganography is proposed for embeddin...

Steganography is the branch of information hiding for secret communication. The simplest and widely used steganography is the LSB based approach due to its visual quality with high embedding capacity. However, LSB based steganography techniques are not secure against statistical steganalysis mainly χ2 attack and Regular Singular (RS) attack. These two staganalysis can easily estimate the hidden...

Steganalytic techniques are used to detect whether an image contains a hidden message. By analyzing different image features between stego-images (the image within which information is hidden) and cover-images (the Image in which information is to be hidden), a steganalytic system is able to detect stego-images. In this paper, we present a new method in LSB embedding by avoiding the change of s...

Steganography is the process of embedding data into a media form such as image, voice, and video. The major methods used for data hiding are the frequency domain and the spatial domain. In the frequency domain, the secret data bits are inserted into the coefficients of the image pixel's frequency representation such as Discrete Cosine Transform (DCT) , Discrete Fourier Transform (DFT) and Discr...

JSteg is a steganographic method for JPEG images that can be viewed as LSB steganography. Recently, we proposed a new principle to detect the use of LSB steganography in digitized vector signals and showed how to apply it to gray-scale images. In this paper, we discuss how to apply it to JPEG images and show some experimental results for the JSteg-like algorithm. Introduction: JSteg-like algori...

We present a steganalysis scheme for LSB matching steganography based on feature vectors extracted from integer wavelet transform (IWT). In integer wavelet decomposition of an image, the coefficients will be integer, so we can calculate co-occurrence matrix of them without rounding the coefficients. Before calculation of co-occurrence matrices, we clip some of the most significant bitplanes of ...

In this paper, we present a novel high bit rate LSB audio watermarking method that reduces embedding distortion of the host audio. Using the proposed two-step algorithm, watermark bits are embedded into higher LSB layers, resulting in increased robustness against noise addition. In addition, listening tests showed that perceptual quality of watermarked audio is higher in the case of the propose...

LSB steganography is one of the popular ways of message embedding in different multimedia cover objects. A number of commercial steganography software tools use LSB insertion as a method of message packing. In the present work the detailed study has been made regarding the stochastic properties of the embedded message and LSB pattern in colour and gray scale images. The influence of the initial...

A novel adaptive steganographic scheme for spatial image is proposed. A noisy function is used to measure texture complexity of 2 × 2 pixel blocks, which keeps monotonic increasing after ±1 modifications. Therefore, the message is embedded into the noisiest areas and the recipient can identify the embedding region. The ‘double-layered embedding’ is exploited to reduce the number of ±1 modificat...
