Abstract

Watermarking is the most smart and appropriate technique for copyright protection and security of multimedia data. Watermarking has been recommended for the civilizing security of biometric systems. Conversely Iris recognition is regard as the most trustworthy and exact biometric identification system accessible. This paper extracted iris feature using a novel grid based approach a Canny Edge Detection (CED) algorithm. The grid based watermarking algorithm uses a hybrid Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT) and method. This method provides a scalable, secure, strong and undetectable form of watermarking. This proposed scheme minimizing fault acceptance rate and the fault error rate in very efficient manner.

基于小波变换的网格虹膜生物特征水印
水印技术是实现多媒体数据版权保护和安全的最智能、最合适的技术。水印已被推荐用于生物识别系统的文明安全性。相反,虹膜识别被认为是目前最可靠、最准确的生物识别系统。本文采用一种新颖的基于网格的方法——Canny边缘检测(CED)算法提取虹膜特征。基于网格的水印算法采用了奇异值分解(SVD)和离散小波变换(DWT)的混合方法。这种方法提供了一种可扩展、安全、强大和不可检测的水印形式。该方案有效地降低了故障接受率和故障错误率。
