Automated Fingerprint Identification System (AFIS) Room

The AFIS system helps to identify crime scene fingerprints by comparison to a database of known fingerprints. This room also contains a fingerprint enhancement system.

The AFIS system is a computer software-based system which contains a database of ten-prints and palm-prints of known origin which can be added to at leisure. The system allows for input of images of individual fingerprints or palm-prints, possibly from a crime scene, which are then mapped by the system algorithms. These maps are then compared automatically with the database to produce a list of candidate matches which the fingerprint analyst can evaluate as to whether they match or not, i.e. do the unknown prints belong to someone in the database.

This room also contains a fingerprint enhancement system (digital capture system – DCS5) which consists of a very high-resolution digital camera linked to a specialist software system and various light sources. This allows the operator to image a fingerprint and to visually enhance it using different light sources and filters and by the use of the software, which tracks any changes made to the image.
