ConclusionDigital watermarking technology represents a data hiding techniques that is used to embed useful information in multimedia object.The proposed technique is classified on different criteria mainly on the domain to spatial domain watermarks, frequency domain watermarks and wavelet domain watermarks.Recently many proposed algorithms searches the use of watermarking for 3D object.The experimental result show that the proposed method is robust against approximately 70 % of attacks.
