A Watermarking Algorithm for Fingerprinting Intelligence Images
نویسندگان
چکیده
The rapid growth of digital multimedia technologies brings tremendous attention to the field of digital watermarking. One application for digital watermarking is fingerprinting. The owner or the distributor of the multimedia data can insert unique watermarks into copies for different customers or receivers, which will be helpful to identify the source of illegal copies. Fingerprinting can be used in an intelligence agency to trace the source of the leak. In this paper, we first identify the requirements for fingerprinting algorithms of intelligence images. Then, we present an algorithm that meets the requirements.

متن کاملA Novel Blind Watermarking of ECG Signals on Medical Images Using EZW Algorithm
Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...
متن کاملSimple Collusion-Secure Fingerprinting Schemes for Images
This paper describes a robust watermarking algorithm and a collusion-secure fingerprinting scheme based on it. Watermarking robustness is obtained by using the JPEG algorithm to decide mark location and magnitude; the proposed algorithm supports multiple marking. The properties of dual binary Hamming codes are exploited to obtain a fingerprinting scheme secure against collusion of two buyers. T...
متن کاملContent adaptive watermarking for multimedia fingerprinting
This paper presents a feasible system for multimedia fingerprinting. One of the important problems of fingerprinting is watermarking strategies for the fingerprints, in other words, where to embed and how to embed. We address these two major problems of fingerprint-watermarking for multimedia in the proposed content-adaptive watermarking scheme. First, the fingerprint codes are often very long ...
