The communication industry is service to the user information transfer of industrial structure,and the speech information is the main carrier communication technology.Due to the communication safety consciousness enhancement,the user of the information transmission process security seriously more,especially on some secret information needed to ensure its security.The operator uses the traditional protection method is the way of information encryption,in using a process actually has exposed many defects.This paper analyzes the information hiding technology and commonly used method,wavelet transform was proposed on the basis of the information hiding algorithm.
