New Biometrics Device Helps Marines Determine Friend or Foe (Forensic Magazine)
The BESD system is an ultra lightweight, ruggedized, handheld portable device that collects and stores biometrics information. It compares and matches fingerprints, iris images and facial photos against an internal biometric database to identify individuals encountered on the battlefield. It is an enabler in the areas of detainee management and questioning, base access, counterintelligence screening, border control and law enforcement.
Interesting approach, having the database on the device. On the plus side, storing the data locally takes connectivity issues out of the equation. There are, however costs. To stay current, the device has to be synched with a central data repository from time to time. There are limits to the amount of data that can be stored on a handheld device. Also, since the data is on the device, there needs to be really good data security in the device itself.
