Signature Systems on Smart Card with Keys Generated by Fingerprint
2006
Fingerprint has usually been used for verification function in order to resist illegal access to secret keys. In this paper, we first propose two signature systems based on smart card where the private key is stored in the smart card and is only accessible when the signer's finger-print matches his template. Later, we present another new signature system where the private key is generated by signer's fingerprint and a small integer, and there is no matching process and no private key is stored on the smart card. The private key recurs whenever the signer's live-fingerprint and a rememberable key are inputted, and the private key can not be illegally leaked.
