Abstract: Adaptive Neuro-Fuzzy Inference System(ANFIS) is a neural network system with one input and several outputs, which is got through achieving one step sugeno fuzzy system by the format of network. It can simulate the connection of the in-out very well, and its constringency is very soon, error is very little and the necessary swatch is little, which are very favourable for blind separation of watermark signals.Based on the upstanding adaptive control ability of ANFIS, a strongly robust audio watermarking algorithm in DCT domain was given in this paper. Experiments show that the performance in watermark detection is high, the time expense is litlle, the resisting to attacks is strong and the imperceptibility is good.
