In order to detect latent fingerprints on a particular surface, fingerprint technicians must employ an appropriate sequence of physical or chemical techniques, and a computer program based on expert system technology has been developed to facilitate the choice of a particular fingerprint detection sequence.
Abstract
The application of a logical and proven sequence of fingerprint detection techniques optimizes the chance of latent fingerprint detection on a given object. Certain steps are involved in elaborating an appropriate sequence of fingerprint detection techniques: determine the nature and state of the surface under investigation; select the relevant techniques for the surface; and construct a logical sequence from the chosen techniques. Known as Goldfinger, a computer program has been developed to help fingerprint technicians develop the best sequence of techniques for latent fingerprint detection. The program uses Microsoft Windows and requires at least a 386-based computer. It requires about 5 seconds to calculate detection sequences for a particular set of conditions and groups techniques into three categories: high-priority (recommended), medium- priority, and low-priority (techniques with major disadvantages). Goldfinger serves as a valuable store of information on operating conditions, reagent formulations, and precautions. Experienced fingerprint technicians may not require such a system for routine casework, but Goldfinger may be a useful aid in difficult cases and in technician training. 6 references and 6 figures
