Abstract: The traditional information hiding method is hiding secret image into vector image，hidden depth is not deep，the method is single and easy analyzed，the hidden information capacity is small.This paper proposes an information hiding method through image mix and wavelet transform double information hiding methods，it hides color secret image into color vector image.In the simulation results，this method has very good hidden feature，the large hidden information capacity and resisting statistical analysis feature，the method is complex and difficultly analyzed.
