Streszczenie
In the Electronic Confirmation of Receipt (Elektroniczne Potwierdzenie Odbioru – EPO) program implemented by the Polish Ministry of Justice since 2014, the addressee signs a confirmation of delivery with a digitally captured signature (DCS; also known as a dynamic signature, biometric signature, etc.). In the course of this action, the writing movement is being sampled and saved as a sequence of biometric data in files called EPO cards. In the presented research, 150 such files were examined in order to verify if the biometric data are suitable for calculating and visualising the features that are indicated in the literature as the most important in forensic identification of DCS. Three types of EPO cards differing in data encoding were distinguished and all of them were assessed as suitable for forensic identification. Difficulties resulting from comparing biometric data from different types of EPO cards were highlighted and measures to improve their mutual compatibility were proposed.
