Fragile watermarking is one of the effective techniques for authentication of digital documents and images. However, recovering the content of the tampered region in a watermarked image is a challenging task while considering conflicting criteria of imperceptibility and watermark embedding capacity. In this paper we propose a Chinese remainder theorem(More)
We propose a Chinese remainder theorem (CRT)-based computationally efficient self-recovery watermarking technique for multimedia applications. Taking few examples of digital images we have shown that the proposed technique can recover the tampered region in the watermarked image quite effectively. Using an optimal quantizing technique we generate a 21-bit(More)
