Fangwei Li · Journal of Chongqing University of Posts and Telecommunications · 2006
In this paper,the authors introduce three random numbers and the Hash function to the weak blind scheme in order to solve the problem of signature traceable in some known blind signature schemes.Then,the authors propose an untraceable multi-blind signature scheme to keep not only the privacy but also the security in a proper environment which can be put into practice in the application of e-check payment.
