Digital media can be copied very easily resulting in security issues. 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, or documents which is used for identifying the original creator and owner of digital content. In this paper discrete wavelet transform technique is used for embedding and extraction of watermark in original image by using alpha blending. The results show that the DWT technique is robust against various common imageprocessing operations. Key Words: Digital watermarking, Discrete Wavelet transform, Alpha Blending. 1. INTRODUCTION Digital media can be stored efficiently and can be manipulated very easily using computers, resulting in various security issues. The problem of protecting the copyright of digital media can be solved by digital watermark. Digital watermarking is a concept of hiding ownership data into the multimedia data, which can be extracted later on to prove the authenticated owner of the media. Watermarking ensures authenticating ownership, protecting hidden information, prevents unauthorized copying and distribution of images over the internet and ensures that a digital picture has not been altered. There are basically two methodsforwatermarking:spatial domainand frequency domain. Spatial domain watermarking slightly modifies the pixels of randomly selected subsets of image pixels depending upon the image perceptual analysis. Frequency domain selects and modifies some frequencies from their original values according to particular rules. The frequency domain techniques are more popular than spatial domain techniques because it produces more robust and imperceptible watermarking. Based on the extraction technique watermarking algorithmsarebroadlycategorized into two: Blind and Non-blind watermarking. The former does not require original image for extraction whereas the later requires original image for extraction process. In this paper non-blind watermarking is used which requires original image for extraction. The purpose of this paper is to study and implement Discrete Wavelet Transform (DWT) domain image watermarking system for real time image. The paper is organized as follows. Section II contains general watermarking model. Section III contains DWT watermarking scheme, proposed techniques for watermark embedding and extraction and section IV contains experimental results. 2. GENRAL MODEL OF DIGITAL WATERMARKING A generalized watermarking model consists of two processes: watermark embedding and detection as shownin Fig. 1 and Fig. 2. In the embedding process, the watermark may be encoded into the cover image using a specific key. This key is used to encrypt the watermark as an additional protection level. The output of theembeddingprocess,thewatermarked image, is then transmitted to the recipient. In the detection processalsocalled extractionprocessthe watermark is extracted from the attacked signal. During the transmission if the signal is unmodified then the watermark is still present and can be extracted. Fig -1: Watermark Embedding Fig -2: Watermark Detection 3. DISCRETE WAVELET TRANSFORM DiscreteWavelet transform (DWT)isamathematicaltool for hierarchical decomposition of an image. The transformation is based on decomposing a signal into wavelets or small waves, having varying frequency and limited duration. The properties of wavelet decompose an original signal into wavelet transform coefficients which contains the position information. The original signal can be reconstructed completely by performing Inverse Wavelet Transformation on these coefficients.

The bands are LL, LH, HL and HH. Fig. 3 shows the sub bands in DWT. LL contains low frequencies both in horizontal and vertical direction. HH contains high frequencies both in horizontal and vertical direction. HL contains high frequencies in horizontal direction and low frequencies in vertical direction. LH contains low frequencies in horizontal direction and high frequencies in vertical direction. The low frequency part comprises of the coarse information of the signal while high frequency part comprises of the information related to the edge components. The LL bandisthemostsignificantbandas it contains most of the image energy and represents the approximations of the image. Watermarks can be embedded in the high frequency detail bands (LH, HL and HH) as these regions are less sensitive to human vision. Embedding into these bands increases the robustness of the watermark without having additional impact on the quality of theimage. At each level of decomposition, first DWT is performed inthe vertical direction, followed by the DWT in the horizontal direction. The first level of decomposition yields four sub- bands: LL1, LH1, HL1, and HH1. The LL sub band of the previous level is used as the input for every successive level of decomposition. This LL sub-band is further decomposed into four multi resolution sub-bands to acquire next coarser wavelet coefficients. This process is repeated several times based on the application for which it is used. DWT has excellentspatio-frequencylocalizationproperty that has been extensively utilized to identify the image areas where a disturbance can be more easily hidden. Also this technique does not require the original image forwatermark detection. Therefore it is used in various applications associated with signal processing like compression of audio and video, removal of noise. Digital image watermarking consists of two processes first embedding the watermark with the information and second extraction. Fig -3: Sub-bands formed after 1-level DWT 3.1 Watermark Embedding In this process 2D DWT is performed on the cover image that decomposes the image into four sub-bands: low frequency approximation, high frequency diagonal, low frequency horizontal and low frequency vertical sub- bands. Similarly 2D DWT is performed on the watermarkimagethat has to be embedded into the cover image. Here we have used Haar wavelet. The technique used for inserting watermarkis alpha blending. The decomposed componentsofcoverimage and watermark are further multiplied by a particular scaling factor and are added. During the embedding process the size of the watermark should be smaller than the cover imagebut the frame size of both the images should be made equal. The watermark embedded inthispaperisperceptibleorvisiblein nature, so we embedded it in the low frequency approximation component of the cover image. Alpha Blending Technique According to the alpha blendingtechniquethewatermark image is obtained by: WMI= k*(LL1) +q*(WM1) Where WMI=Watermarked image, LL1=low frequency approximationoftheoriginalimage,WM1=Watermarkandk, q = Scaling factors for the original image and watermark respectively. Finally inverse discrete wavelet transform is performed on the watermarked image coefficient to generate the final secure watermarked image. Fig -4: Watermark Embedding Process 3.2 Watermark Extraction In this process thestepsappliedintheembeddingprocess are applied in the reverse manner. First discrete wavelet transform is applied to both cover image and the watermarked image. After this the watermark is recovered from the watermarked image by using alpha blending technique. Alpha Blending Technique The alpha blending formula used for watermark extraction is given by: RW= (WMI - k*LL1) Where RW=Recovered watermark, LL1=Low frequency approximation of the original image, WMI=Watermarked image. Finally inverse discrete wavelet transform is performed on the watermark image coefficient to generate the final watermark extracted image.

EXPERIMENTAL RESULTS In this paper we have used pepper image as the cover image and the fruits image as the watermark which are shown in Fig. 6 (a) and Fig. 6 (b) respectively. Both the images are of equal size of 512×512. The alpha blending technique used here adds the low frequency contents of the two images hence both images of equal size are taken. Fig -6(a): Cover image Fig -6(b): Watermark image to be embedded Fig -7: Watermark embedding process 1-level DWT Fig. 7 shows watermark embedding process.Fig. 8 shows the watermarked image. Watermark embedding is done by varying the value of k from 0.1 to 0.9 keeping q constant at 0.1. Best results are obtained when k is 0.5. With the decreasing value of k below 0.4 watermark image gets brighter and completely destroys the cover image. Fig -8: Watermarked image Fig. 9 shows the watermark extraction process. Fig. 10 shows the extracted watermark image. Recovery of watermark image is done by varying value of k from 0.1 to 0.9. With the decreasing value of k below 0.2 recovered watermark becomes darker and completely invisible. Fig -9: Watermark extraction process 1-level DWT
