Authentication and tamper detection in images using dual watermarking approach

Watermarking of multimedia content is important to authenticate, copy-control and ownership detection. In this paper, multimedia authentication and tamper detection scheme is proposed with the security of AES(Advanced Encryption Standard) ciphered watermarking and hash function. The algorithm embeds two watermarks in the host image for authentication and tamper detection. We first used Unique Identification Code (UIC) as first robust watermark which is then embedded using the 2-level discrete wavelet transform. Hash code of host image is calculated and used as secondary watermark for tamper detection. This method is blind in nature. The PSNR, SSIM values are used as a metric to test the efficiency of the enhanced watermarking technique. The results show that the imperceptibility of method is high as compared to the existing.
