Abstract

Based on the example of activities performed in the Forensic Laboratory of the Police Headquarters in Szczecin in the case of the Central Police Investigation Bureau, the article presents the issue related to the possibility of obtaining investigation material for fingerprint examination in the form of graphic files and video files secured from smartphones with images of fingers and hands. Due to the high quality of a photograph and a single frame from a video, it was possible to positively identify the person, which made it possible to largely substantiate the person’s involvement in the criminal act. The widespread access to smartphones that enable taking and sharing high-quality graphic files, as well as a huge number of photographs and videos shared on the Internet, with increasing frequency, in combination with simple tools for processing video frames and unsophisticated procedures for rescaling traces in AFIS, make a new form of obtaining material for fingerprint identification in the form of a digital fingerprint, and may become more significant.
