Digital watermarking is the method of altering a piece of data in order to incorporate data-related information. In some cases, the watermarks may be visible so unauthorized persons can easily access the data. In order to protect the information from being copied and used without authorization, a unique technique is proposed. In this research a Fibonacci transform based image scrambling technique is proposed to enhance the security by applying scrambling algorithm to watermark before embedding them with input images. The proposed work is compared with another scrambling technique called Random Shuffling method and the sample size for each group is 30. The performance of image scrambling algorithm is measured using Structural similarity index measure (SSIM) and Universal index quality measure (UIQI) parameters. Low values of SSIM and UIQI indicates better scrambling. Fibonacci transform provides mean SSIM values of 15.8723%, mean UIQI of 66.8050% and Random shuffling method provides mean SSIM values of 23.0210% and UIQI of 76.2750%. Based on experimental results and statistical analysis using Independent sample T test, the Fibonacci transform based image scrambling method performs significantly better than Random Shuffling method with SSIM (P=0.007) and UIQI (P=0.008).
