The enciphering method comprises following steps. A plurality of content objects which are divided from a digital content are received. DRM vectors are generated according to tacit information between the DRM enciphering apparatus and the DRM deciphering apparatus. The content objects are respectively enciphered to generate DRM objects base on the DRM vectors. : ():( 2 ) (): 21~23:,:
