This chapter discusses lessons that can be learned in biometrics from the field of the forensic sciences. It acknowledges the fact that biometrics and forensics are both very old research disciplines which have a very different perspective in life: While work in biometrics is mostly focused on application issues, like achieving certain error levels, forensics need a very thorough backing to achieve the ultimate goal in this field, admissability in court. This automatically results in high standards for methods that exceed simple performance issues by far. One aspect that is used in this chapter as the focus of the discussions is the matter of privacy. In the first half of the chapter it is illustrated by example how current research work in one digitized forensics field, here digitised dactyloscopy (i.e. the science of forensic analysis of fingerprint traces), influences the current view on fingerprint biometrics and which lessons in regards to privacy can be derived. In the second half, the ever popular field of face biometrics is addressed as an example of an widely used biometric modality in desperate need of not only digital image forensics but also guidelines for privacy preserving methods.
