A Novel Watermarking of Images Based on Wavelet Based Contourlet Transform Energized by Biometrics
Authors: , ,
Abstract: The progress and the substantial procreation of web technologies have created an environment in which some crucial issues for digital media have become very easy. The phenomenon has led to an increasing need for developing some standard solutions to prevent these issues. One of the technical solutions is to provide law enforcement and copyright protection for digital media which can be achieved practically by Digital Watermarking. The proposed method contains following phases (i) Pre-processing of biometric image, (ii) Obtaining keys from the biometrics of the owner/user and Speeded-Up Robust Features (SURF) is used as the scale- and rotation-invariant detector for biometric images, (iii) Wavelet-Based Contourlet Transform (WBCT) is applied on the host image, (iv) Singular Value Decomposition (SVD) is enforced over the watermark image, (v) Embedding of the host image with the Watermark Image and (vi) Watermark Extraction and Attack Analysis. The implemented proposed system SURF provides execution time of 98% over SIFT. The comparative analysis confirms the efficiency and robustness of the proposed system.
