The proposed scheme has an advantage that after a signature was converted, the converted signature is indistinguishable from normal partially blind signatures.
This paper introduces a new concept of convertible user designating confirmer partially blind signature, in which only the designated confirmer (designated ...
However, Chien, Jan and Tseng presented a cryptanalysis of Wu's scheme to show that it is not secure. Moreover, they proposed a modified version of Wu's scheme.

Abstract: Any one who knows the signer's public key can verify the validity of a given signature in partially blind signature schemes.
A directed signature scheme allows a designated verifier to directly verify a signature issued to him, and a third party to check the signature validity with ...
