These categories are, unlike in the classical biometric case, established and time–proven by humans with the aim of differentiating individuals.
In other words the soft biometric traits instances are created in a natural way, used by humans to distinguish their peers.
He first proposed a personal identification system based on biometric, morphological and anthropometric determinations.
[4] Such soft biometrics are well suited to deployment in surveillance applications [5] and research is ongoing to capitalise on these developments.
[6] An example is visual surveillance, and soft biometric information can help identify people during the inconsistencies when faces are captured poorly on camera.
