Enhanced Image Security Using Fingerprint Based Watermarking System

In multimedia technologies has simplified the ways for the transmission, reproduction and manipulation of data. The digital content can be protected against counterfeiting, piracy and any unauthorized access by digital watermarking. Digital watermarking is an essential technique to add copyright notice, secret messages or verification messages to digital image signals, audio, video which is used for identifying the original creator of digital content. The image watermarking algorithm is developed where fingerprint biometric identification image is inserted to it. Discrete wavelet transform technique is used for embedding and extraction of watermark in original image by using LSB which as fingerprint biometric image as watermark. Among all the biometric identities, the fingerprint is most reliable identification system. The fingerprint trait is chosen because of its higher accuracy and reliability. The results show that the DWT technique is robust against various common image processing operations. Performance of method for different value of scaling factor is analyzed by using statistical parameters such as peak signal-to-noise-ratio (PSNR) and mean square error (MSE).
