Digital Watermark Scheme for Joint Ownership Based on the LUC Cryptography
He Ying · Journal of Kunming University · 2011
A novel digital watermark scheme for joint ownership based on the LUC cryptography is designed.In the scheme,with LUC public-key cryptography,each participant computes the watermark embedding block to embed watermark information,and the identity of each participant is verified,so the scheme can prevent participants from cheating in the watermark embedding and extraction process.Moreover,the scheme can achieve blind extraction.The experimental results show that the proposed scheme is robust against some attacks such as JPEG compression,Gaussian noise,salt and pepper noise.
