We present a new model for undeniable signatures: fair-anonymous undeniable signatures. This protocol can not only preserve the privacy of the signer (i.e. anonymity) but also track the illegal utilization of the valid signatures. In addition, our model prevents the trusted centre from forging a valid signature for any signer. Keywords--Cryptography, Fair Anonymity, Information Security, RSA Signatures, Undeniable Signatures.
