Tao Wang · Yunnan Daxue xuebao. Shehui kexue ban · 2007
A multicast watermarking protocol(PALMWP),based on application layer multicast is presented.The protocol is location dependent protocol,so it has the same advantages as other location dependent protocol,such as easier deployment,better scalability.Furthermore,LDPC code is used as a design element to enhance the capability of copyright protection,traitor tracing and leaker identification.Finally,BAN logic is used to deduct the authentication part of the PALMWP.
