生物特征识别只是生物特征识别系统的一个类别，这取决于它作为输入的人类特征的类型。

生物测定学在很大程度上是统计的。可从样本中获得的数据越多，系统就越可能具有独特性和可靠性。它可以在与测量个人的身体和特征以及行为方式有关的各种模式下工作。根据人的生物学特征对模式进行分类。

生物识别方式的类型

人类存在多种特征，可以用作生物特征识别方法。生物识别方式分为以下三种类型-

1.生理学
2.行为上的
3.生理和行为方式的结合

下表收集了区分这三种方式的要点-

Physiological Modality	Behavioral Modality	Combination of Both Modalities
This modality pertains to the shape and size of the body.	This modality is related to change in human behavior over time.	This modality includes both traits, where the traits are depending upon physical as well as behavioral changes.

Physiological Modality

Behavioral Modality

Combination of Both Modalities

This modality pertains to the shape and size of the body.

This modality is related to change in human behavior over time.

This modality includes both traits, where the traits are depending upon physical as well as behavioral changes.

For example −

Fingerprint Recognition
Hand Geometry Recognition system
Facial Recognition System
Iris Recognition System
Hand Geometry Recognition System
Retinal Scanning System
DNA Recognition System

For example −

Gait (the way one walks)
Rhythm of typing keys
Signature

For example −

Voice Recognition

It depends on health, size, and shape of vocal cord, nasal cavities, mouth cavity, shape of lips, etc., and the emotional status, age, illness (behavior) of a person.

在随后的章节中，我们将更详细地讨论每种方式。
