This service stores 400 million biometric templates and makes them available across several European information systems.

Abstract: Template matching (TM) was proposed in the literature a decade ago to efficiently remove non-local redundancies within an image without transmitting any overhead of displacement vectors.

Here's a small example of usage showing the simplest case, a single string.

See the Gatekeeper policy library for a collection of constraint templates and sample constraints that you can use with Gatekeeper.
