Abstract
Based on wavelet transform, an image fusion algorithm was developed to increase the volume of hidden information. The algorithm was able to fuse 16 or 64 watermark images into one cover image. Taking advantage of Haar wavelet transform, the algorithm could recover all hidden images. Simulation tests showed that the proposed algorithm was capable of hiding a large volume of information effectively and securely. It could be used to transmit encrypted military information over the network.
