What if the quality of the captured signature data is not good enough for forensic analysis?
Generally, the quality of the data from signature capturing devices is very good. Nevertheless, signature capturing devices can also be used within thin client environments, such as Citrix, RDP, or VMWare.
In that case, you require a local software component running on the thin client device that receives the data packets from the USB signature pad; otherwise you will lose some of the biometrical data packets due to latency issues. The reason is that signature pads send the data they record with file-and-forget, which is not an issue if the receiving software runs locally. However, in a thin client environment, the buffer that stores the received biometrical data packets may not be read in-time, because access from the receiving software is delayed by the network’s latency. Thus, a simple pass-through that uses USB redirection does not work for signature tablets. Therefore SIGNificant provides a local software component that runs directly on the thin client in the background to read the data packets from the data buffer without any delay, as required for a flawless operation.
