Abstract

In this paper, a simple watermarking scheme for digital image authentication is proposed. The insertion of a binary watermark is accomplished by adding to the lower frequency subband of discrete wavelet transform (DWT) decomposition of host image with a random binary image obtained by random permutations. The proposed scheme is secure, fast, and is immune of the well-known quantization attack. Especially the watermark extracting process has no need of the original image.
