Ling Lin · China Information Security · 2007
Information hiding technology is very important for copyright protection and secret communication. In this paper,based on the concept of information hiding,we proposed a secure voice communication system. By introducing echo into voice signal,secret information can be hidden in exoteric information. The scheme is simulated and analyzed on its performance. The details of the scheme are also discussed from the point of the sensitivity of hominine hearing.
