The majority of biometrics vendors today concentrate on law enforcement, surveillance and forensic applications. Is such a vendor the best choice when it comes to authentication applications, such as virtual and physical access control or transaction authorization? To answer that question, we need to understand what these applications have in common and how they differ.
All of these applications share some characteristics. They all need capture of biometric information in order to compare it with information from one or more previously captured samples. They all are typically implemented in large scale with high performance requirements. And they all require a fair degree of accuracy. However, there are some very important differences between the two groups of applications.
