Abstract

In Schwarz 1 an amino acid model for printing latent fingerprints to porous surfaces is introduced, motivated by the need for reproducibility tests of different development techniques for forensic investigations. However, this technique also enables the fabrication of artificial traces constituting a possible threat to security, motivating a need for research of appropriate detection techniques. In this paper a new framework for modelling the properties of a generic fingerprint examination process is introduced. Based on the framework, examination properties and detection properties are derived by a subjective evaluation. We suggest a first formalisation of exemplary properties, which can be easily extended to fit different needs. We present a first experimental setup limited to two printers and the Schwarz amino acid model using absorbing and non-absorbing material with first results to show tendencies and underline the necessity for further research.
