The German Federal Ministry of Education and Research (BMBF) announced that “Following the publication of “pattern recognition” of the BMBF * under the program “Research for Civil Security of the Federal Government funded project Digi-Dak (digital fingerprints, digital fingerprint) are pattern recognition techniques for fingerprints, which are covered with non-contact optical 3D surface sensing, explored. General aim is to improve and support the criminal forensics (fingerprinting).

The project was on the reproducibility of the experiments of Schwarz (2009) presented amino acid model for the printing of latent fingerprints on porous surfaces used. This is motivated by the need for reproducible testing of various developing technologies for forensic investigations. However, this technique can also use it to deliberately leave fingerprints at the scene by bystanders with printed art welding. One potential threat both for the person themselves and for the general safety dar. The project Digi-Dak hence the need has been about the exploration of suitable detection techniques derived from art welding and identify important features for recognition of printed fingerprints.

The results to date have been at the SPIE Conference: Image Quality and System Performance presented VIII in San Francisco in January 2011. The FRT-sensor technology [3], the latent fingerprints collected and analyzed for particular characteristics of the printing process. The researchers have presented a generic fingerprint examination process as a framework to study and recognition properties of artificially printed fingerprints compared to real fingerprints to the subjective examination to provide and support the work in the forensic laboratory.

Initial tests with two printers for absorbent and non-absorbent materials are already showing a high recognition performance, but also motivate the need for further research. These works have a considerable novelty value and are a basis for expansion.”
