The paper described several major three - dimensional geometric information hidden technology and detection technology. And on this basis the paper discussed the technical principle of information hiding and detection of hidden infor- mation in X_2 algorithm, based on the assumption that the hidden information is subject to uniform distribution. According to the difference of the embedded information before and after the index value, the algorithm can find hidden information. Fi- nally the example proved that the method is effective.
