A Secure Internet-Based Personal Identity Verification System Using Lossless Watermarking and Fingere client side, the SHA-256 hash of the original fingerprint image and sensitive personal information are encrypted and embedded into the fingerprint image using an advanced lossless data hiding scheme. At the service provider side, after the hidden data are extracted out, the fingerprint image can b

Better Use of Human Visual Model in Watermarking Based on Linear Prediction Synthesis Filterter, whose parameters are derived from a set of just noticeable differences estimated by HVM. After being filtered by such a filter, the watermark can be adapted to characteristics of human visual system. As a result, the watermark visibility is noticeably decreased, while at the same time enhancing

Weighted Segmented Digital Watermarking author and where each author is considered to be of different importance relative to the other authors. We specifically examine weighted segmented watermarking for still images and generalise previous work on performance measurement of watermark embedding patterns in the presence of cropping attack

CLAIM

Robust Estimation of Amplitude Modification for Scalar Costa Scheme Based Audio Watermark Detectionhese kinds of watermarking algorithms do not need an original host signal for watermark detection and the host signal does not affect the performance of watermark detection. For practical implementation, they mostly use uniform scalar quantizers, which are very vulnerable against amplitude modificat

Reversible Data Hiding Using Integer Wavelet Transform and Companding Techniquetakes advantage of the Laplacian-like distribution of integer wavelet coefficients in high frequency subbands, which facilitates the selection of compression and expansion functions and keeps the distortion small between the marked image and the original one. Experimental results show that this sche

Alteration-Locating Authentication Watermarking for Binary Images quite a small number of cryptography-based secure authentication methods are available for binary images. This paper proposes a new authentication watermarking method for binary images. It can detect any visually significant alteration while maintaining good visual quality for virtually all types o

Steganographic Scheme Using a Block Ciphertection method, so-called RS steganalysis. In this paper we propose a steganographic scheme using a block cipher, which minimizes the embedding changes of a cover object utilizing not only the LSBs of the cover object’s strings but also the whole bits of the cover object. The proposed scheme is a ki
