In the common signature system, the signed document can be verified illimitably, anyone can verifies its validity with the group key. but in some special setting, large numbers of verifier are not appropriate, sometimes document can only be verified by some designated people. this paper proposes the designated - verifier group signature scheme with the udvs on acjt. at last this paper implements the multi - bank system with above schemes, remedies the limitation of forgoing schemes, and resolves the par value problem. the par value is designated by the bank, and it is binding with the signature, thus the problem of user cheating can be avoided
