%X According to grey relation theory and the characteristic of information hiding,a new calculation method for grey relation coefficient was defined.Furthermore, and a new information hiding algorithm based on color image was proposed.This algorithm justified LH and HL frequency band coefficients in DWT(Discrete Wavelet Transform) of original carrier image and hid the secret data in LH and HL frequency band coefficients of color carrier image's every color weight.The secret data was extracted according to grey relation coefficient and the cover image was not needed.The experimental results show that the algorithm is not only invisible,but also robust against various signal processing such as noise adding,cropping,JPEG compression,and filtering.
