This paper presents an adaptive watermarking method based on Fruit Fly Optimization algorithm (FOA)Using the global optimization characteristics, the optimal embedding strength of each group of experiments is adaptively determined by constructing an appropriate fitness function. Using the characteristics of Hessenberg decomposition and singular value decomposition, an image watermarking algorithm in wavelet transform domain is designed. The watermark information is embedded into the frequency domain of the host image to enhance the anti‐attack ability of the algorithm. The robustness of the watermarking scheme is analyzed through various types and different intensity simulation attack experiments. The experimental results show that this method is more robust than similar algorithms on the premise of ensuring good watermark concealment.
