Based on the improved Brands’ e-cash scheme, it is expanded by adding two roles, government and judges. The user can keep unconditionally anonymous in normal transactions. Authorized by the judges, the government can remove the identity of an illegal user with the help of the bank. So such misuse as blackmailing or money laundering can be prevented. Therefore, this scheme is more efficient, more suitable for adopting pre-processing and post-processing and more practical. In the paper, the details of the scheme are described, its security is proved, and its efficiency is analyzed.展开更多

Previous studies show that pay for performance sensitivity of Japanese executive compensation is positive and almost the same as in a market-oriented system like that of the United States of America (USA). However, previous studies do not investigate how Japanese corporate governance mechanisms like financial keiretsu ties and bank-appointed directors affect pay for performance sensitivity. This paper finds that the disciplinary mechanism of keiretsu memberships and bank-appointed monitors did not function well in Japan in the 1990s.展开更多
文摘In this paper, an efficient fair e-cash system is presented. Based on the improved Brands’ e-cash scheme, it is expanded by adding two roles, government and judges. The user can keep unconditionally anonymous in normal transactions. Authorized by the judges, the government can remove the identity of an illegal user with the help of the bank. So such misuse as blackmailing or money laundering can be prevented. Therefore, this scheme is more efficient, more suitable for adopting pre-processing and post-processing and more practical. In the paper, the details of the scheme are described, its security is proved, and its efficiency is analyzed.
