Abstract：In order to protect medical image information,this paper presents a new algorithm of medical volume data digital watermarking based on Legendre chaotic neural network.It integrates Legendre chaotic neural network,three-dimensional discrete Fourier transformation and zero-watermarking.On the one hand, a novel Legendre chaotic neural network is used to generate a chaotic sequence with a pseudo-random sequenc for scrambling the original watermark image.On the other hand,zero-watermarking is constructed in the three-dimensional discrete Fourier transforming domain of medical volume data.The simulation results show that the digital watermarking algorithm not only has good robustness,but also good security and confidentiality.
