The commercial reuse of 3D motion capture (Mocap) data in animation and life sciences raises issues with respect to its copyright. In order to improvise content protection of Mocap data, we devise a substitutive blind watermarking technique. This technique visualizes 3D Mocap data as a series of non-intersecting cluster of triangles. Bits are encoded inside the triangles by using an extended substitutive bit encoder in spatial domain. The encoding supports watermark imperceptibility and develops robustness against affine transforms (rotation, translation, scaling), noise addition, reordering and sample loss attacks. Security of the scheme can be enhanced by adding secret embedding distances between clusters, which are based on a secret key used for watermarking purpose.
