The information embedding based on the embedding using the lifting principle (LPE) that a quality embedding image can be made by performing high, order embedding [5]. In our previous work [3]. the Linking Number (LN) to the plane in the RGB color space of the watermark image by LPE was defined [2]. And it was shown that this LN could serve as an index for alteration detection of a watermark image. In this paper, the following things are showed by the experiment using the standard image, i) M dimension color space has 2M over three dimensional plane structure, ii) LN to this plane is used as an index for alteration detection of an embedding image, iii) LN for this detection is obtained by choosing suitably the three dimensional space in M dimension space, iv) This selection can have the application possibility to verification that can adjust the degree of detection according to quality of image.
