Using Hybird Genetic Algorithm In Audio Steganography

In this paper, a proposed method for hiding secret data in audiofile (.WAV) is introduced. Genetic algorithm has been hybridized withconjugate gradient algorithm which is one of the methods for solvingnonlinear unconstrained minimization problem, the hybrid geneticalgorithm is used to determine the optimum positions for Leastsignificant bit (LSB) by substituting the least significant bit of eachsampling point with a binary message.Numerical results for the proposed hybrid genetic algorithm onthree test function were reported and compared with the results ofgenetic algorithm, also two measures were used such as BER (Bit ErrorRate) and MSE (Mean Square Error) in order to access the performanceof the proposed steganography method.
