Dear sir/madam,

I need a source code for the Bio-metric project.

Bio-metrics refers to metrics related to human characteristics. Bio-metrics authentication (or real authentication) is used in computer science as a form of identification and access control.  It is also used to identify individuals in groups who are under surveillance.

Bio-metric identifiers are then distinct, measurable characteristics used to label and describe individuals. Bio-metric identifiers are often categorized as physiological versus behavioral characteristics.  Physiological characteristics are related to the shape of the body. Examples include, but are not limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina and odor / scent. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythm, gait,  and voice. Some researchers have coined the term behaviors to describe the latter class of bio-metrics. 

 Since bio-metric identifiers are unique to individuals, they are more reliable in verifying identity than token and knowledge-based methods; However, the collection of bio-metric identifiers raises privacy concerns about the ultimate use of this information.
