The application of asymmetric digital watermarking in commercial model
Fengying Wang · Journal of Shandong University of Technology · 2007
In view of the insufficiencies of conventional symmetric watermarking,the asymmetric digital watermarking plan were proposed by the use of public-key cryptosystems.However,most plan concentrated on digital products' copyright before transaction,didn't involve tracing pirate after transaction or the legitimate rights of customers.This paper proposes a kind of asymmetric digital watermarking plan which is relative integral in the commercial model.The plan may effectively protect the merchants' interests,trace pirate,and permit customers to identify the piracy by browsing watermarking information.At the same time,it can also prevent merchant from bring a false charge against customers.In a word,it ensures the legitimate rights of merchant and customers.
