Coding theorems for biometric systems

Ignatenko and Willems (2009) proved coding theorems for a biometric secret generation model and a biometric secret transmission model. But, they treated only the case of perfect secrecy and they did not consider the coding rate of a public channel. In this paper, we derive general coding theorems including the coding rate of a public channel in the case of general security levels for secret information and biometric information.
