Design of Protection in Iris Biometric Recognition Using Watermarking Technology

Abstract

In order to handle this problem, researches have proposed dissimilar algorithms to be challenged by security of biometric systems. Two major ways are, (1) Encryption, and (2) watermarking by securing biometric images and templates. In this project, we utilize a watermarking technology to improve the template security in biometric authentication. According to, two modalities such as, iris and hand vein is taken to preserve the characteristics of liveliness and permanency. The existing technique of embedding of iris data to hand vein images using watermarking technology consist of following steps, i) preprocessing of iris and hand vein images, ii) iris template extraction, iii) Vein extraction, iv) Embedding of iris pattern to vein images based on region of interest, v) Storing embedded images. After this the extracted iris template was embedded in to the hand vein and stored in the database. Subsequently in recognition phase the iris template and hand vein features were extracted from the watermarked image. Finally the extracted features were matched with input query image.
