Abstract: This paper investigates the capacity of a special kind of information hiding models based on the nested lattice in coding theory, introduces the formula of the capacity, and presents the methods of the information embedding and extracting to achieve the capacity. The information embedding and extracting methods based on lattice theory are explained by a simple example.

Key words: Information hiding, Hiding capacity, Gauss distribution, Nested lattice theory
