A Secure Reversible Watermarking Algorithm for Image Authentication

By embedding reversible watermark,the original image can be recovered from the watermarked image when it is deemed to be authentic.To improve watermark security,a high secure reversible watermarking algorithm is proposed which adopts parameterized integer wavelet transform and the features of integer wavelet coefficients in the detail bands. Experimental results demonstrate the proposed scheme has good invisibility,high security and accurate localization for tampered area.
