    Abstract: We present an efficient information hiding algorithm for
    polygonal models. The decision to referencing neighbors
    for each embeddable vertex is based on a modified breadth
    first search, starting from the initial polygon determining
    by principal component analysis. The surface complexity is
    then estimated by the distance between the embedding
    vertex and the center of its referencing neighbors. Different
    amounts of secret messages are adaptively embedded
    according to the surface properties of each vertex. A
    constant threshold is employed to control the maximum
    embedding capacity for each vertex and decrease the model
    distortion simultaneously. The experimental results show
    the proposed algorithm is efficient and can provide higher
    robustness, higher embedding capacity, and lower model
    distortion than previous work, with acceptable estimation
    accuracy. The proposed technique is feasible in 3D
    adaptive information hiding.
