Online-Submitting System Based on a Safe and Anonymous Protocol

In today´s society, there are more and more Onlinesubmitting Systems recently. For example, the system of submitting the excessive amount of exhaust which can regulate the misconducts set up by Department of Environmental Protection. Though the system seems like very convenient, there are some hiding problems like anonymity, verifiability, non-repudiation, and lying problem. Here we propose a protocol that is safe and anonymous. By using public key cryptosystem, partially blind signature and multi-authority structure, this proposed scheme can not only protect the reporter´s privacy well but also help the institution and the reporter to reduce the cost and the human resource.
