AN IMPROVING MODEL WATERMARKING WITH IRIS BIOMETRIC CODE

INTRODUCTION

We using one algorithm of the discrette wavelet transformation DWT, which sends itself in wise Haar for performing in water sign. The discrette wavelet transformation is relatively new notion, which wants to change the purpose (Or Filler) Broad used discrette transformation of the cosine (DCT) that uses itself in Compression JPEG. The Purpose a method on this in use biometric discriminating line is provided digital scene. The Copyright Protection- digital scene offers the method with use one Bio measured feature,and as follows: iris-play-off owner, who identifies his(its) synonymy Embedding watermark.The Input signal elements are a transport image, which must be protected for this method, watermark has took into consideration include. She standing with compute the rubbish for iris-play-off of the code of the pattern human. The Algorithm,which is elected to be an execution, which lifted contribution uses the obvious wave transformation so it is named transformation Haar, what include the water volumes of the mark in seconds level wavelets(2- two levels DWT), and two levels HL2 and two justify LH2 region. Since the message defines on these level information in less degree on image because of this also change (include the noise) on image and they will less. Here, it is necessary to addiction as is mentionned also in picture-machine and quality on water mark. This dependency solves as information, e.g. volume on water mark, can change without visibility of the garbling the rebel against transport image.The Used watermark in offered models - also digital image, which is elected to be on to grey scale of the format BMP.

The Number water sign must be according to with size transport image, this can be gained program. In undefended event this not carry in checkmore lung completion doubtful displacement to be capable observer changes quality introductions to other frame-transport and other water sign.For embedding the watermark is using setup the generator of whatever worth's uses itself, as he is installed with respect to chosen by us switch e. g. this hash worth had calculated for the concrete iris-code. The used hash function is MD 5 (Algorithm 5 Message Digest), from which we receive 128-BIT code. Each Hash value will be different on the different pictures to irises - but the goal is alone worth for digests is being got here unique worth for Iris code.
