This paper proposes an identity verification system using data hiding and fingerprint recognition. At user's home, the client's account information is encrypted and embedded into the fingerprint image via data hiding method secretly. Then the fingerprint image with embedded data is transferred to the bank over Internet. At bank side, the client's account information is extracted. It is used to retrieve...
This paper presents a novel steganalysis scheme to effectively attack the JPEG steganographic schemes. The proposed method exploits the correlations between block-DCT coefficients in both intra-block and inter-block sense. We use Markov empirical transition matrices to capture these dependencies. The experimental results demonstrate that the proposed scheme is superior to the existing steganalyzers...
In this paper, a new semi-fragile lossless digital watermarking scheme based on integer wavelet transform is presented. The wavelet family applied is the 5/3 filter bank which serves as the default transformation in the JPEG2000 standard for image lossless compression. As a result, the proposed scheme can be integrated into the JPEG2000 standard smoothly. Different from the only existing semi-fragile...
