    Abstract: Partially blind signature is an important cryptographic primitive in privacy oriented e-commerce applications. In INDOCRYPT 2003, Zhang <I>et al</I>. proposed a new partially blind signature scheme more efficient than previous schemes. It was later showed linkable by Chow <I>et al</I>. and then respectively improved by both Chow <I>et al</I>. and Zhang <I>et al</I>. at the cost of poorer efficiency. However, in this short study we show that the cryptanalysis of Chow <I>et al</I>. is wrong. So the original partially blind signature scheme remains secure and the corresponding  improvements are needless.
