Original Abstract

The paper examines the possibilities of exploiting a dynamic biometric signature (hereinafter referred to as “DBS”) by forging a DBS when having knowledge of the signature dynamic. An experiment was carried out on test subjects who are assumed to have adequate expertise and mental qualifications and signing skills on scanning devices and the motivation to achieve the best possible result. The subjects had at their disposal throughout the experiment a static display of the signature and of its dynamic in the form of repeated display of a progressively created signature. Moreover, each subject knew the name of the person providing the signature. Each subject was able to repeat attempts to provide a forgery with no time limit until such time as he/she considered the forged signature to be as similar to the original as possible. The results showed that the level of success among the forgers was very low and was reduced according to the required degree of conformity of signatures for acceptance by audit software. It was shown that DBS is highly resistant to forgery by another person under standard conditions. In addition to having an undoubted ability to forge, this also requires that the conditions be in place in which it is possible to analyse the dynamic of the signature provided. It was also shown that success in forging the DBS of another person does not depend on the number of attempts and is rather a matter of the individual abilities of the forgers.
