Abstract
The goal of this article is to investigate an alternative capacity for steganographic systems. We will define steganographic capacity as the maximum number of embeddable bit within a digital signal while maintaining imperceptible requirements. This capacity makes it somewhat possible to solve two fundamental steganographic problems: first, how to choose the best cover image among classes of images and second which embedding method may be employed to reduce the detection of hidden information within the embedded areas. In addition, the new capacity may be used for 1) the separation of an analyzed image into embeddable areas, 2) the identification of maximum embedding capacities within a cover digital image, and 3) estimating the length in bits used for embedding information within the identified regions.
