Blind signature allows a user to obtain signatures from an authority on any document, in such a way that the authority learns nothing about the message that is being signed. The blindness is an important property in blind signature scheme. In this work, we analyze security of the blind signature[1], and show that the scheme hasn't blindness, in other words, the signer is able to link a valid message-signature pair obtained by some user. To overcome the above flaw, we propose an improved scheme and show that the security of the improved scheme is based on the Computational Diffie-Hellman problem.
