      The usage of online signatures is more and more common, and it is an important expectation to be able to identify which signatures are genuine and which are forgeries. To capture an online signature, we need some special electronic devices. Many of them can capture the pen movements even when it is slightly lifted. Online signatures practically consist of a series of data points. Some approaches do not use all captured points, only some selected ones. This paper studies the relevance of the usage of pen-up points. For that, we compared three different cases of gap handling. First, the verifier uses the signatures in their original form as they were acquired, so there is captured information for the gaps. Besides, this paper studies two preprocessing algorithms, first, the removal of the gap points, and second, their removal and regeneration. The experimental results show that the effects of the usage of pen-up points depend on the quality of the verification systems.
