【Abstract】 In this paper, after explaining the concept of information hiding, we proposed a secure (and convert) voice communication scheme, which can be used in digital communication systems. By introducing echo into voice signal, secret information can be hidden in exoteric information. The performance of this scheme is simulated and analyzed. The detail of the scheme is also discussed from the point of view of the sensitivity of hominine hearing.更多还原
