Hiding Secret Data in an Image Using Codeword Imitation
This paper proposes a novel reversible data hiding scheme based on a Vector Quantization (VQ) codebook. The proposed scheme uses the principle component analysis (PCA) algorithm to...

Texture generation over the marker area
In this paper, we present a method for generating a texture for hiding a marker in augmented reality applications. The texture is generated by interpolating the neighbourhood of t...

Optimal strategies for spread-spectrum and quantized-projection image data hiding games with BER payoffs
We analyze spread-spectrum and quantization projection data hiding methods from a game-theoretic point of view, using the bit error rate (BER) as the payoff, and assuming that the...

Secure data hiding in binary document images for authentication
In this paper, we present a data hiding algorithm for binary document images. This algorithm is based on the DistanceReciprocal Distortion Measure [1] that is used to evaluate the...

Image dependent log-likelihood ratio allocation for repeat accumulate code-based decoding in data hiding channels
Error correction codes of suitable redundancy are used for ensuring perfect data recovery in noisy channels. For iterative decoding based methods, the decoder needs to be initiali...
