For quite a few years the biometric recognition techniques have been developed. Here, the authors briefly review some of the known attacks that can be encountered by a biometric system and some corresponding protection techniques. They explicitly focus on threats designed to extract information about the original biometric data of an individual from the stored data as well as the entire authentication system. In order to address security and privacy concerns, they present a biometric authentication scheme that uses two separate biometric features combined by watermark embedding with hidden password encryption to obtain a non-unique identifier of the personage.
