Soft Biometrics

Soft Biometrics is the science of soft biometric characteristics that describe human behavior or physical characteristics. Further accessories that can be used to describe a person to be counted. In contrast to the classic biometrics, the soft biometric features are classifiable in human compliant and established categories that were traditionally the distinction of individuals.

Formation

The beginnings of soft biometrics Alphonse Bertillon presented when he developed a human identification system that was based on biometric, morphological and anthropometric characteristics in the 19th century. This system included features such as the color of eyes, hair, beard and skin; the shape and size of the head; but also the body size or weight and, further, birthmarks, scars or tattoos. The vast majority of these descriptors fall at the present time in the category of soft biometrics.

Recently discovered Jain soft biometric features as a set of properties that provide information about a person, but that person can not completely authenticate because they are of low discrimination power and durability.

Soft Biometric features

Characteristics that accept the above definition, but not be limited to:

• Physical: skin color, eye color, hair color, presence of beard and mustache, head shape, facial features, body size and weight.
• Behavior: Gang keystroke.
• Accessories: clothing color, presence of headgear, bags.

Soft Biometric characteristics inherit a majority of the advantages of the classic biometrics, but have quite beyond their own strengths. Some of the new benefits are the unobtrusive detection, it does not require the consent or cooperation of the observed. Furthermore, the detection and evaluation of the characteristics is effort and time efficiency and requires no learning phase ( enrollment). Finally, they are human Compliant, so you can do a search using human descriptions initiate.
