Yarovenko V.V., Kitaev N.N. On the issues of development of dactyloscopy

Abstract: This work was motivated by the constant attention of the scientists and practicians to improvements in dactyloscopy due to development of scientific and technical means and scientific milestones in criminology and forensic science on identification. The authors examine the problems of reasonableness of implementation into law enforcement of delta index, symbol dactyloscopic formula as a combination of ridge patterns of the palm and fingertips, as well as other dermatoglyphical traits of the ridge patterns. A special attention is given to the argument that the symbol dactyloscopic formula can serve as biological marker of adaptive phenotype, allowing forecasting emergence of criminally significant events by the ridge patterns of the individual. Analysis was conducted on the research of ridge patterns by other authors from previous years, as well as ridge patterns of persons who committee violent crimes in a number of Russian regions. The results and comparison with the proposed prospects of development in dactyloscopy and dermatoglyphics by other authors reveal that neither the numerical nor symbol formula is sufficient for identification of a specific individual. The research needs to be conducted on the morphological images of the ridge patterns of fingertips, which will allow avoiding mistakes.
