This study adopts a triangle subdivision scheme to achieve reversible data embedding. The secret message is embedded into the\nnewly added vertices. The topology of added vertex is constructed by connecting it with the vertices of located triangle. For\nfurther raising the total embedding capacity, a recursive subdivision mechanism, terminated by a given criterion, is employed.\nFinally, a principal component analysis can make the stego model against similarity transformation and vertex/triangle reordering\nattacks. Our proposed algorithm can provide a high and adjustable embedding capacity with reversibility.The experimental results\ndemonstrate the feasibility of our proposed algorithm.
