Biometrical Imaging

Biometry or biometrics is currently in the limelight, largely because this technology is likely to be used in the near future for passports and many other applications related to security and identification. However, biometry has not reached the end of development yet. The performance for many applications is not yet good enough and a lot of research is required to obtain the necessary improvements. In this article we provide some insight into the technology used and we not only discuss how and why biometry works but also why the systems sometimes fail.
