Primary and Secondary Data
• Data are not “Absolute Truth”
• Primary data
– Data closest to “Absolute Truth”
– The most valid and illuminating data
• Secondary data
– Derived from primary data
– The form of data usually used by the researcher
in attempting to discover the truth

• “Absolute Truth” = true identity of person
• Primary data
– Fingerprint image, possibly only partial or distorted
• Secondary data
– Features (minutiae points) taken from the image
– The form of data usually used by the researcher to
discover the truth, in this case the person’s identity
