Biometrics and information hiding, as two different yet promising techniques for individual identification and digital media protection, have been extensively studied in the latest decade. Recently, hybrid approaches that combine these two techniques (i.e., biometric information hiding) for advanced information security have obtained increasing research interest. The principle idea is applying information...
In this paper we propose a watermarking based two-stage authentication framework to enhance biometric system security. The face feature of one individual is embedded into his/her fingerprint image as credibility token. During authentication, the watermark is first extracted to establish data authenticity. If legitimate, the face pattern can further serve as supplemental trait in biometric authentication...
Compared with traditional personal identification techniques such as passwords and PIN codes, automated biometrics authentication provides a convenient and reliable method in diverse applications, but their validity must be guaranteed. Watermarking technique may be a solution to ensure the validity of biometrics. In this paper, a novel scheme of protecting hidden transmission of biometrics using authentication...
This paper proposes a novel robust watermarking scheme to embed fingerprint minutiae into face images for multimodal biometric authentication. First, a block pyramid is layered according to the block-wise face region distinctiveness estimated by Adaboost; upper level indicates informative spacial regions. Then, we adopt a first-order statics QIM method to perform watermark embedding in each pyramid...
In this paper, a Novel PCA-based authentication watermarking scheme with superior localization and security is proposed. The input image is partitioned into non-overlapping 8 ?? 8 image blocks. An alternate representation of these image blocks is obtained based on principal component analysis (PCA). The authentication watermark bits are generated from the first m coefficients among these blocks. In...
In this paper, a novel scheme to protect biometric templates using LBP-based authentication watermarking is proposed. Firstly, the m-LSB (a generalization of LSB) of biometric templates is set to zeros. Then, the modified biometric templates are partitioned into non-overlapping n X n image blocks. The LBP feature of these image blocks can be obtained, and the authentication watermark bits are generated...
