This paper proposes a partially blind signature scheme based on discrete logarithm and analyzes its security and performance.This scheme is partially blind,untraceable and unforgeable.It prevents user abusing signature and ensures that the identity privacy of message provider can not be infringed by the signer.The scheme is more efficient than the two others based on Schnorr signature algorithm and DSA changed signature algorithm respectively.
