In this reseacrh so it will be created an algorithm of multilayer data hiding with architecture of data authentication protocol as modification detection code for hidden data. digital certification agreement of multilayer data authentication protocol and digital certificarion agreement for multilayer data protection must be agreed between transmitter and receiver, how to process data. in this reseacrh wo it will be created an algorithm of tree authentication coding to create book authentication, an algorithm of tree authentication decoding which it will be applied on book authentication, how to create multilayer data protection. and finally simulation and theoretical modeling of multilayer data hiding will be created with modeling of data authentication protocol.
