In this paper, we propose a new approach using both the Citizen Digital Certificate and anonymous identification to fulfill the back-end real-name and front-end anonymous verification requirements in an online transaction. Anonymous identification is a simple design to establish the link between the real name and the pseudonym (account ID) selected by the user during the registration, in which the reverse-lookup is not allowed so that the anonymous verification is achieved. The back-end real-name mechanism in this model plays an important role which requires total fairness and trust. Thus, we use the government MOICA as the trust back-end platform, which issues the Citizen Digital Certificate and thus will have the user’s real-name. The main purpose of the front-end anonymity mechanism is that, the online shopping store does not know the real identities of its customers but pseudonyms. The customer is able to conduct a transaction anonymously in a normal circumstance, in which his/her privacy is preserved. The back-end real-name mechanism will be activated only when crime events occur. In such cases, anonymity will be removed through legal means to trace the real identity.
