Novel Iris Biometric Watermarking Based on Singular Value Decomposition and Discrete Cosine Transform

Abstract

A novel iris biometric watermarking scheme is proposed focusing on iris recognition instead of the traditional watermark for increasing the security of the digital products. The preprocess of iris image is to be done firstly, which generates the iris biometric template from person's eye images. And then the templates are to be on discrete cosine transform; the value of the discrete cosine is encoded to BCH error control coding. The host image is divided into four areas equally correspondingly. The BCH codes are embedded in the singular values of each host image's coefficients which are obtained through discrete cosine transform (DCT). Numerical results reveal that proposed method can extract the watermark effectively and illustrate its security and robustness.

Sayısal Görüntülerin Telif Hakkının Korunması İçin İris Tabanlı Biyometrik Damgalama Yaklaşımı

“…Çalışmada kör olmayan damgalama yöntemi kullanıldığı için, şemanın algısal kalitesi yüksektir, ancak dayanıklılığı test edilmemiştir. Bir başka iris tabanlı çalışmada göz görüntüsünden AKD yardımıyla elde edilen ikili iris kodu, AKD-TDA tabanlı yöntemle orijinal görüntüye gömülür [14]. Bu çalışma algısal kalite ya da dayanıklılık sonuçlarını rapor etmemiştir.…”

Integrated Discrete Wavelet Transform and Singular Value Decomposition based Biometric Watermarking for Authentication using Iris Images

“…Innovative iris biometric watermarking arrangement was suggested by Lu et al (2014) [19] concentrating on iris identification rather than conservative watermark approach to enhance protection. Pre-analysis of iris image was carried out initially to produce iris biometric pattern with respect to individuals.…”

Digital Image Watermarking Techniques and Biometrics Data Security: A Review

“…Lu et al [35] proposed a scheme that in order to increase the security focuses more on iris identification rather than on the digital watermarking. DCT is applied on the iris pattern and the obtained value is then encrypted into the Bose-Chaudhuri-Hocquenghem (BCH) code for error control.…”
