In this paper, we describe a new biometric Identity Based Signature (IBS) scheme based on the Sakai Kasahara Key Construction and prove its security in the framework of a stronger security model compared to exisiting adversarial models. Besides, we present a new type of a denial of service (DoS) attack and evaluate existing biometric IBS schemes in this context. Based on the recently defined privacy notions, we show that our scheme achieves weak signer-attribute privacy and the security is reduced to the k-DHI computational problem in the ROM with an efficient reduction. Finally, our scheme is compared to other error tolerant signature schemes and shown to be much more efficient in terms of its each phase.
