AB  - Digital image watermarking is a technique for include secret information to the digital data to prove the authenticity. A digital watermarking is perceptually invisible to prevent obstruction of the original image. It is also used for tamper proofing, broadcast monitoring, covert communication etc. In this study a Fibonacci transform based watermarking approach for thrashing watermark image in host images is proposed. The host image is renewed into LL3 sub band of the host image. For increase the security level, apply Fibonacci Transform into the host image and then find SVD values for that. Apply DWT and SVD to that covert image. Finally covert image is embedded into the host image. This proposed methodology overcomes the drawback of the existing approaches and enhances the security by applying Fibonacci transform for embedding the resultant pattern in the host image. The watermark embedding process does not degrade the visual quality of the image.
