Abstract
Biometric authorization and registration systems and methods are disclosed. In one embodiment, the system preferably comprises a firearm that includes a biometric authorization system, a plurality of training computers, and a server. In the preferred embodiment, the server and the training computer interact to train the biometric authorization system in the firearm to accurately and reliably discriminate between the authorized user and unauthorized users. The server utilizes a training algorithm that takes into account biometric information of not only the authorized user of firearm, but also those of a large number of unauthorized users. Such biometric information is utilized to compute one or more discriminants and thresholds for such discriminant(s), which are then transmitted to the biometric authorization system in the firearm. If the user is allowed to operate the firearm a predetermined percentage of the time, the discriminant thresholds are fixed. If not, the server adjusts the thresholds, and the process is repeated. In another aspect of the present invention, the system may be utilized to uniquely register the firearm with the authorized user. Similar training algorithms are also disclosed for training biometric authorization systems in devices other than firearms.
