| Abstract(in English) | We have proposed a digital contents circulation system on Blockchain. The system can protect user’s privacy from both contents providers and agencies that assure user’s attributes. While authorized contents provider and user can trace their transactions, an unrelated person also can trace them. We propose an improved system to solve this problem. In this paper, we discuss the improved digital contents circulation system on Blockchain. |
