Abstract

OWING TO PERSONAL COMPUTERS BEING APPLIED INMANY FIELDS, MOST INFORMATION IS TRANSMITTED WITH DIGITAL FORMAT SUCH AS TEXT DOCUMENTS, AUDIO, IMAGES AND VIDEOS. WITH THE RAPID GROWTH OF THE INTERNET AND THE DEVELOPMENT OF MULTIMEDIA NETWORK SYSTEM , ILLEGAL COPYING, TAMPERING, MODIFYING AND COPYRIGHT PROTECTION HAVE BECOME VERY IMPORTANT ISSUES AND THAT IS A CHALLENGING TASK TO PROTECT COPYRIGHT OF AN INDIVIDUAL IS CREATION. SO, THERE IS GREAT NEED OF PROHIBITING SUCH ILLEGAL COPYRIGHT OF DIGITAL MEDIA. DIGITAL WATERMARKING PROVIDES A VIABLE SOLUTION TO PROTECT COPYRIGHT AND ACKNOWLEDGE THE OWNERSHIP OF AN INTELLECTUAL PROPERTY. IN THIS PAPER, WE PROPOSE A METHOD OF NON-BLIND TRANSFORM DOMAIN WATERMARKING BASED ON DWT-DCT. IT PERFORMS 3 LEVEL DWT OF ORIGINAL (COVER) IMAGE AND THEN WATERMARK IMAGE WOULD BE EMBEDDED IN THE MIDDLE-COEFFICIENTS OF DCT TRANSFORMED OF SUBBANDS( LL3) OF COVER IMAGE. THE PARAMETERS USED TO TEST THE ROBUSTNESS AND TRANSPARENCY OF THE PROPOSED ALGORITHM IS THE PEAK SIGNAL TO NOISE RATIO (PSNR) AND SIMILARITY RATE (SR). EXPERIMENTAL RESULTS SHOW THAT COMBINING THE TWO TRANSFORMS IMPROVED THE PERFORMANCE OF THE WATERMARKING ALGORITHM. MOREOVER, THIS METHOD PROVIDES HIGH IMPERCEPTIBILITY AS WELL AS HIGH ROBUSTNESS AGAINST DIFFERENT ATTACKS SUCH AS JPEG COMPRESSION, GAUSSIAN NOISE, SALT & PEPPER NOISE, ETC. ...
