Disclosed is a 3D mesh model watermarking method using a divisional scheme. The method of inserting a watermark into a three-dimensional (3D) mesh model includes: calculating a geometric primitive of the 3D mesh model; dividing the 3D mesh model into a plurality of mesh segments by using the geometric primitive; converting the mesh segments into mesh segments of a vertex distance-based coordinate system; inserting a predetermined watermark into each of the mesh segments of the vertex distance-based coordinate system; and restoring the mesh segments into which the watermark is inserted to a Cartesian coordinate system.
