Application of digital technologies in fingerprinting (transition to creation, storage and research of materials in electronic format)

Abstract

The subject of the study is the fixation of traces and impressions of papillary patterns of fingers and palms of hands with digital devices and scanners. The research methodology is based on the analysis of modern scientific provisions and expert practice on digital technologies used in fingerprinting. Attention is paid to private scientific methods of cognition: description, comparison of signs of papillary patterns obtained electronically. The empirical component of the study confirms the need to obtain fingerprint information by the traditional method - by using printing ink to stain papillary patterns of fingers and palms of hands, which makes it suitable not only for fingerprinting, but also for poro- and ejeoscopic examination. В The main conclusions of the study conducted by the authors on the use of digital technologies in fingerprinting in electronic format is that when fixing and scanning a papillary pattern, proper image quality is not provided, small details (hook, peephole, fragment) are distorted, and private features are lost. When processing fingerprint information by scanners, errors are made, technical failures occur in the operation of the ADIS. Illustrative materials of poor quality cast doubt on the reliability and evidentiary power of fingerprint examination. Comparative study of handprints and fingerprints of the persons being checked with the help of ADIS "Papilon" can be used only as an auxiliary method.
