Copyright protection scheme for determining scope of tamper person
Jinglei Guo · Computer Engineering and Applications Journal · 2011
In real life,people want to know the tamper person position after the digital work is tampered.This paper proposes a copyright protection scheme for determining the scope of tamper person using fragile watermark and multiple robust zero watermark,which is combined with timestamp and digital signature technology.The experiment results show that the proposed scheme has high validity and robustness.In general,the scope is very small.
