Abstract Blind digital signature indeed protects interests of the participants to some extent, but the anonymity of blind digital signature present exploit opportunities to attackers. Aiming at problems of current fairness blind digital signature schemes can not simultaneously guarantee completely fairness and can not recover message, the paper proposed a kind of message-recoverable fairness blind signature scheme and analyzed its correctness, security and fairness. The analysis results show that the just can authorize user's identity and correspond it to original signature message with this scheme, and the user can not forge fairness information of just.
