In steganography, several different types of media have been used as carriers, such as images, audios and video streams, to hide secret data. Nevertheless, various novel media and applications have been developed due to the rapid growth of internet. In this paper, we select maze games as carrier media to conceal secret data. The original idea of embedding data in a maze is proposed by Niwayama et al. Their method has two disadvantages. One is the very small embedding capacity; the other is that the stego maze is not perfect. Here, we propose an improved algorithm for increasing the embedding capacity and preserving the "perfect" property. (C) 2010 Elsevier Inc. All rights reserved.

It is common to use image, audio, video streams as host media in steganography. In this paper, we will select mazes as host media to avoid the problem "robustness" concerned by classic host media. The original idea of embedding data in a maze is proposed by Niwayama et al. Their method has two disadvantages. One is very small embedding capacity; the other is that the embedded maze is not perfect. Here, we present an improved algorithm to increase the embedding capacity. Meanwhile, we can still preserve the property "perfect", that is, we can keep the imperceptible property required in steganography.
