The management of private keys is a main problem in traditional threshold digital signature system. Combining a method of generating keys from biometric information and a modified RSA signature scheme, a novel biometric based (k, l) threshold signature scheme is proposed in this paper. The signer can sign a message only by his biometric information, and if the number of signers is equal to or more than k in a group of l members, the group signature can be generated. The security analysis results show that the scheme is secure and easy to implement.
