Secure Digital Image Watermarking using Fibonacci Scrambling and Rotational Embedding

Present age is the age of technology where we are all flooded with digital data. As the use of data is increasing day by day, the techniques and algorithms for data manipulation are also increasing at a rapid rate. The advancement in technology has brought about a revolution which has led to identification of various ways and techniques for modification and enhancement of images. On the other hand it also brings various challenges with respect to the prevention of tampering, forging or misuse of electronic data in form of image, audio or video. Digital watermarking can prove to be a very useful technique in prevention of any such scenario. Verifying the integrity of delicate images, such as medical photos, is crucial since even the smallest distortion or alteration might lead to a wrong diagnosis. Especially in digital images, watermarking techniques give protection from any such attack to a large extent. This research paper proposes a novel approach to digital image watermarking using a combination of Fibonacci scrambling, rotational embedding, and the Discrete Cosine Transform (DCT). The objective of the proposed algorithm is to bolster the security and resilience of the watermarking process through the incorporation of supplementary encryption and obfuscation mechanisms. We have implemented the code for this algorithm in Python
