Would fingerprint scanners be useful for weapons

Mobile identity verification using fingerprints

The determination of identity in police operations today is largely based on the verification of proof of identity, for example the identity card, passport or residence permit. The use of fingerprints to establish identity takes place mainly in the stationary recognition service. Since the beginning of 2006, fingerprints can also be scanned on patrol duty using the FAST-ID procedure and compared with the AFIS of the BKA. Single fingerprint readers are usually installed in the vehicle and operated from there.




A really mobile, biometric recording of a person, regardless of the availability of a patrol car, was previously not possible or only to a limited extent due to technical limitations. In the meantime, the battery capacity and the processor performance of mobile devices, the availability of intelligent applications and the transmission speeds of the data networks have increased enormously, so that there are no limits on the IT side for the use of mobile devices. With the introduction of 5G technology at the latest, the speed of data transmission using mobile devices will no longer be inferior to a connected network.




As in IT and cellular technology, there have recently been rapid advances in the field of recording technology for fingerprint scanners. Until a few years ago, an external power supply and a bulky suitcase or a patrol car were required for transport and power supply, but today modern fingerprint scanners can be operated using a laptop, tablet or even a mobile phone. The mobile devices basically have two functions:




a) The control of the fingerprint scanner and the recording of the fingerprints


b) Sending the fingerprints to the AFIS and receiving the search results


c) The power supply of the fingerprint scanners




Today's mobile devices are so powerful that they can also be used to carry out more complex work steps and database queries.




However, the interaction between the mobile device and the fingerprint scanner is decisive for practical use. Size, weight and handling play an important role in the daily use of such systems. The latest fingerprint scanners use a technology from the display area to capture fingerprints. This significantly reduces the size and weight of such devices. The extremely compact and light fingerprint scanners are therefore predestined for mobile use.




The LIVETOUCH QUATTRO Compact is an example of the new generation of highly compact fingerprint scanners. Just as light and compact as today's smartphone, the device is in no way inferior to conventional fingerprint scanners in terms of fingerprint quality.




Certified by BSI and FBI




The LIVETOUCH QUATTRO Compact has already been certified by the Federal Office for Information Security (BSI) and the American FBI for recording flat and rolled fingerprints. Despite its small size, the scanner can take four flat fingerprints at the same time.




With this technology, ten fingerprints can be recorded for the first time on the move. In other words: the acquisition of ten fingerprints pressed and rolled allows not only a verification of the identity of a person, but also their acquisition. In connection with a mobile device (mobile phone, tablet or laptop), fingerprints, facial images, tattoos and ID documents of people can be recorded on patrol duty, at major events or raids.




With the option of recording all ten fingers, not only is there a higher probability of hits in the databases, but the recording process is also significantly simplified and the security of the officer is increased.




The practical handling is not only determined by size and weight, but also by the connection to the mobile device. Various options are available here, ranging from a wired solution to various wireless transmission options. If the fingerprint data is transmitted wirelessly, the fingerprint scanner must also be equipped with a battery. The specific application and the legal framework often decide on the appropriate design of the connection for data transmission between the fingerprint scanner and the mobile device.




shows an example of an integrated case solution. Here the LIVETOUCH QUATTRO Compact is integrated in a case and is controlled and supplied with power with the tablet, which is also in the case. The case is extremely compact and the arrangement of the devices enables fingerprint capture in the case; it is therefore not necessary to remove the devices beforehand.




Another possible application for the mobile capture of fingerprints is shown. In this compact solution, the LIVETOUCH QUATTRO Compact is directly connected to the mobile phone. The mobile phone is connected to the fingerprint scanner via an integrated docking station. In this scenario, the fingerprints can be captured with one hand, so that the police officer always has a free hand. It is also advantageous that the person to be identified has no way of viewing the result of the ID check, since the display of the mobile phone is aimed at the police officer. When closed, both devices can be transported safely, and the mobile phone can still be used to take photos of faces or documents.


Of course, these fingerprint scanners can also be operated with any laptop.




For use in robust scenarios, the fingerprint scanner can be provided with a plastic frame (bumper) that protects the device from damage.




Conclusion: With the technological advancement of fingerprint scanners and the constant advances in mobile technologies, identity capture using biometrics is becoming a reality in daily police operations. This important building block fits seamlessly into the concept for better availability of information in police operations and supports the implementation of the “Police 2020” program. Of course, such a mobile registration does not replace the stationary identification service, but it can be used for a secure and time-saving identity check in the field that goes beyond the proof of identity on the basis of documents.
