Paper Abstract

The elliptic curve cryptographic random sequences as watermark are embedded in wavelet transform domain of the cover image. This algorithm takes advantages of the multiresolution feature of wavelet transform and non-relevant feature of the cryptographic random signal. The cryptographic random sequences are generated by the elliptic curve group and Galois Field function selected. The experimental results demonstrate that the scheme proposed is security, invisible and robust against commonly image processing techniques.
